5V0-35.21 VMware vRealize Operations Specialist Questions and Answers

 The vRealize Operations sizing tool is a web-based tool that helps you estimate the resources required for deploying and running vRealize Operations in your environment. The tool has two modes: Basic and Advanced. In the basic mode, you only need to enter information about vCenter objects, such as the number of clusters, hosts, virtual machines, and datastores. The tool also asks for the projected growth rate and data retention period for your environment. Based on these inputs, the tool provides recommendations for the node size, cluster size, and disk space for vRealize Operations. The tool also shows the maximum number of objects and metrics that can be collected by the recommendedconfiguration123. Therefore, the attribute that is required for using the vROps sizing tool in basic mode is the number of clusters. The other attributes, such as the number of virtual machine disks, vSwitches, and port groups, are not required in the basic mode. However, they can be entered in the advanced mode, along with other data sources, such as management packs, vRealize Automation, vRealize Log Insight, etc., to get a more accurate and customized sizing recommendation123. References: 1: Introducing the vRealize Operations Sizing Tool 2: vRealize Operations 8.6.0, 8.6.1, and 8.6.2 Sizing Guidelines 3: Everything You Need To Know About vRealize Operations Manager Sizing Tool

According to the VMware vRealize Operations User Guide1, tags are labels that can be assigned to objects in vRealize Operations to group them based on common attributes or criteria. Tags can be used to filter, search, and organize objects in vRealize Operations, as well as to define policies, alerts, dashboards, and reports. Tags can also be used to configure tiers, which are logical groups of objects that represent different levels of service or performance in the environment. For example, the administrator can create tiers such as Gold, Silver, and Bronze, and assign tags to the objects that belong to each tier. Then, the administrator can use the tags to apply different policies, alerts, or dashboards to each tier.

One of the grouping options in vRealize Operations that allows the configuration of tiers is Tags. This option allows the administrator to create custom groups based on the tags assigned to the objects. The administrator can select one or more tags to define the membership criteria for the custom group. The administrator can also specify the object type and the adapter type for the custom group. The custom group can then be used to configure tiers in vRealize Operations.

Therefore, the correct answer is A. Tags, as this is the grouping option in vRealize Operations that allows the configuration of tiers. References:

To enable east/west firewall in VMware Cloud Director Tenant Portal, you need to perform the following steps:

• Login to Customer Organization and go to Networking Section of Tenant Portal. This is where you can access the networking capabilities provided by NSX Data Center for vSphere in your VMware Cloud Director organization virtual data center.
• Go to Edge Gateways and enable firewall on one of the Edge Gateways. This will allow you to configure the edge gateway firewall rules for north/south traffic enforcement and perimeter security functionality. You can also enable other services such as NAT, VPN, load balancing, etc. on the edge gateway.
• Go to Networking and enable Distributed Firewall for one of the Network inside the Network section. This will allow you to configure the distributed firewall rules for east/west traffic isolation and access control. You can also apply security policies and groups to the network and the virtual machines within it.

To monitor VMware Site Recovery Manager with vRealize Operations, the administrator must download and install the vRealize Operations Management Pack for VMware Site Recovery Manager, which is a software package that extends the functionality of vRealize Operations and provides dashboards, alerts, and metrics for Site Recovery Manager objects and services1. The management pack can be downloaded from the VMware Marketplace2 or the Site Recovery Manager download page3. After downloading the management pack, the administrator must install it by using the vRealize Operations interface and upload the PAK file4. Then, the administrator must configure the Site Recovery Manager appliance account in Integrations, which is the section where the administrator can add, edit, or delete accounts for various data sources and adapters5. The administrator must provide the Site Recovery Manager appliance IP address or FQDN, the username and password, and the SSL certificate thumbprint. After configuring the account, the administrator can view the Site Recovery Manager dashboards, alerts, and metrics in vRealize Operations. References: 1: vRealize Operations Management Pack for Site Recovery Manager - VMware 2: VMware Marketplace - View Solution 3: VMware Site Recovery Manager Downloads 4: Installing the Management Pack 5: [Integrations] : [Configuring the Site Recovery Manager Adapter Instance]

According to the VMware vRealize Operations Install and Configure Guide1, when upgrading the vRealize Operations cluster via the Administration UI, the cluster status should change from offline to online after the upgrade process is completed. However, if the cluster status remains offline or fails during the upgrade, the administrator can use the Finish Installation option to resume the upgrade process. The Finish Installation option attempts to bring the cluster online and complete the upgrade. The administrator can monitor the progress of the upgrade from the Administration UI or the Cluster Management page.

The other options are not suitable for managing this problem and continuing the installation process. The Rollback Installation option is used to revert the cluster to the previous version of vRealize Operations, not to resume the upgrade process. The Rollback Installation option is only available if the cluster is online and the upgrade has failed. The administrator should not manually take the cluster offline, as this would interrupt the upgrade process and cause data loss or corruption. References:

• 1: VMware vRealize Operations Install and Configure Guide, https://docs.vmware.com/en/vRealize-Operations/8.5/vrealize-operations-manager-85-installation-and-configuration-guide.pdf, page 54-55, 58-59

Data nodes are the type of node in a vRealize Operations (vROps) design that allow an administrator to scale out vROps to monitor very large environments. Data nodes are additional nodes that have all the vROps services installed, such as UI, Controller, Analytics, Collector, and Persistence. Data nodes perform data collection and analysis, and increase the capacity and performance of the vROps cluster. Data nodes can be added or removed as needed to adjust to the changing workload and environment size. Remote collectors are not a type of node in a vROps design, but a separate component that can be deployed to collect data from remote sources and send it to the vROps cluster. Remote collectors do not store data or perform analysis, and do not increase the capacity or performance of the vROps cluster. Replica Primary nodes and Primary nodes are not the type of node that allow an administrator to scale out vROps to monitor very large environments, but the type of node that provide high availability and continuous availability for the vROps cluster. Replica Primary nodes and Primary nodes contain critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. Replica Primary nodes and Primary nodes do not perform data collection and analysis, and do not increase the capacity or performance of the vROps cluster. References: About vRealize Operations Cluster Nodes, section “About vRealize Operations Cluster Nodes”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

The configuration that was sized using the vROps sizing tool is High Availability. High Availability is a feature of vRealize Operations that allows the cluster to tolerate the failure of one or more nodes, and to ensure the continuity and availability of the vRealize Operations services1. High Availability can be enabled or disabled in the Admin UI of vRealize Operations, and it requires at least two nodes in the cluster2. The vROps sizing tool is a web-based tool that helps the administrator to estimate the size and the resources needed for a vRealize Operations deployment, based on the number and the type of the objects to be monitored3. The vROps sizing tool provides different sizing options, such as Extra Large, Large, Medium, Small, and Extra Small, and shows the specifications and the costs for each option. The vROps sizing tool also allows the administrator to select the configuration mode, such as High Availability, Continuous Availability, Stretched Cluster, or Fault Tolerance, and shows the impact of the mode on the sizing and the resources4. The image that was sent with the question shows the output of the vROps sizing tool, with the configuration mode set to High Availability. The image shows the recommended size as Medium, with 2 nodes, 5564 metrics, and 980812 properties. The image also shows the other sizing options, such as Extra Large, Large, Small, and Extra Small, with their respective specifications and costs. Therefore, the configuration that was sized using the vROps sizing tool is High Availability. Continuous Availability (option B) is not the correct answer, as it is a different configuration mode that allows the cluster to tolerate the failure of an entire site, and to ensure the zero data loss and the near-zero downtime of the vRealize Operations services5. Continuous Availability requires at least four nodes in the cluster, and it uses synchronous replication between the sites. The image does not show the configuration mode as Continuous Availability, nor the number of nodes as four. Stretched Cluster (option C) is not the correct answer, as it is a different configuration mode that allows the cluster to span across two sites, and to ensure the load balancing and the disaster recovery of the vRealize Operations services. Stretched Cluster requires at least four nodes in the cluster, and it uses asynchronous replication between the sites. The image does not show the configuration mode as Stretched Cluster, nor the number of nodes as four. Fault Tolerance (option D) is not the correct answer, as it is not a configuration mode that is supported by vRealize Operations. Fault Tolerance is a feature of vSphere that provides continuous availability for a virtual machine by creating and maintaining a secondary virtual machine that is identical to the primary virtual machine. Fault Tolerance is not applicable to vRealize Operations, as it does not support the clustering and the scalability of the vRealize Operations nodes. References:

 These two methods will meet the goal of creating a trust relationship between the cluster and each of these new nodes. Generating passphrases in the administration User Interface of an existing node, and entering them when prompted in each new node is a method that allows the administrator to securely authenticate the new nodes to the cluster. The passphrase is a one-time password that is valid for 24 hours and can be used to add multiple nodes to the cluster. Clicking the Add New Nodes button on the System Status page in the administration User Interface of an existing node is another method that allows the administrator to initiate the process of adding new nodes to the cluster. The administrator can enter the FQDN or IP address of the new node, and then validate the certificate and accept the trust relationship. Clicking the Add New Nodes button on the Cluster Management page in the product User Interface of an existing node is not a valid option, as this button does not exist on that page. Using any local or directory user with the Administrator role in vRealize Operations when prompted in each new node is not afeasible option, as the new node does not have any local or directory users configured yet. Using the vRealize Operations root user name and password when prompted in each new node is not a reliable option, as the root user name and password may not be the same for all the nodes, and may not be known by the administrator. References: Expand an Existing Installation to Add a Data Node, section “Expand an Existing Installation to Add a Data Node”. Add a Node to a vRealize Operations Analytics Cluster, section “Add a Node to a vRealize Operations Analytics Cluster”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

 The vSphere Solution’s Default Policy is a policy that is automatically created when you add a vCenter Cloud Account to vROps. This policy applies to all the objects that are discovered and collected by the vSphere adapter. The origin of the settings in this policy is the base settings that are provided by the data adapters and solutions installed in vROps. The base settings are a collective group of rules that apply to all objects, regardless of their type or source. The vSphere Solution’s Default Policy inherits all the base settings by default, and you can modify them to suit your specific needs. The default policy setting is not defined by another administrator, nor is it added during the installation of the vROps management pack for vSphere. The settings of this policy are also not defined during the vROps OVF deployment, as they are determined by the data adapters and solutions. References: Default Policy in vRealize Operations, Configure VMware SDDC Benchmarks

A metric configuration in vRealize Operations is a collection of metrics that you can apply to one or more widgets in a dashboard. A metric configuration allows you to customize the metrics that you want to display on the widgets, and also to define the color, label, unit, and aggregation type for each metric. You can create, edit, or delete metric configurations from the Metric Configuration page in the Administration menu1. A metric configuration is not the same as a metric group, which is a predefined set of metrics that you can select from the widget configuration panel2. A dashboard navigation is a feature that allows you to link one or more widgets or views in a dashboard to another dashboard, and pass the selected object as a filter to the destination dashboard. When a dashboard navigation is created, the destination widgets or views are filtered by the selected object from the source dashboard3. An alert can be created from the Alert list widget, which displays the alerts for the selected object or group of objects in a dashboard. You can create an alert by clicking the Add Alert icon on the widget toolbar, and then selecting the alert definition, the object, and the alert properties4. Dashboards can be added by installing management packs, which are extensions that provide additional monitoring and management capabilities for various solutions and platforms. However, dashboards can also be added by creating custom dashboards, importing dashboards from the VMware Marketplace, or cloning existing dashboards. References: 1: Manage Metric Configurations 2: Select Metrics for Widgets 3: Create Dashboard Navigation 4: Create an Alert from the Alert List Widget : [Create and Configure Dashboards]

The generate passphrase option allows the vRealize Operations administrator to create a one-time passphrase that can be used instead of the administrator credentials to add a node to the cluster. This option is useful when the administrator wants to delegate the task of adding a node to another user without exposing the administrator password. The passphrase is valid for 24 hours and can be used only once. The trainee administrator can use the passphrase to authenticate into the vRealize Operations Manager administration interface and then select the Expand an Existing Installation option to add a new node intothe cluster1. References: 1: Expand an Existing Installation to Add a Data Node

The regulatory, standards-based compliance pack that is available in vRealize Operations is the CIS Security Standards. The CIS Security Standards are a set of best practices and recommendations for securing IT systems and data against cyberattacks. The CIS Security Standards are developed and maintained by the Center for Internet Security (CIS), a nonprofit organization that provides cybersecurity resources and guidance to organizations and individuals1. The vRealize Operations Compliance Pack for CIS provides alerts, policies,and reports to validate the vSphere resources against the CIS hardening guide. The following resources are being validated using this content: ESXi Host, Virtual Machine, vCenter Server, Distributed Switch, Distributed Port Group, and Distributed Firewall2. The vRealize Operations Compliance Pack for CIS can be downloaded and installed from the VMware Marketplace3. The Sarbanes-Oxley Act (SOX) (option A) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. SOX is a federal law that regulates the financial reporting and auditing of public companies in the United States. SOX does not provide specific technical guidelines or benchmarks for securing IT systems and data4. The Common Vulnerabilities and Exposures (CVE) (option B) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. CVE is a list of publicly known cybersecurity vulnerabilities and exposures that are assigned unique identifiers and descriptions. CVE does not provide specific security standards or recommendations for securing IT systems and data5. The General Data Protection Regulation (GDPR) (option D) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. GDPR is a legal framework that regulates the collection, processing, and transfer of personal data of individuals in the European Union and the European Economic Area. GDPR does not provide specific technical guidelines or benchmarks for securing IT systems and data. References:

 A published catalog is a catalog that is made available for access by organizations outside the VMware Cloud Director installation. A published catalog can be consumed by a different VMware Cloud Director instance in a different country, as long as the system administrator has enabled external catalog publishing for the organization that owns the catalog,and the remote organization has subscribed to the catalog1. A published catalog can contain vApp templates and media files that are synchronized between the publisher and the subscriber, and can be used to deploy vApps and VMs in the remote organization2.

The other options are not correct. A subscribed catalog is a catalog that is created by subscribing to a published catalog from another organization. A subscribed catalog cannot be shared across VMware Cloud Director instances, as it is dependent on the published catalog1. A content library catalog is a catalog that is synchronized with a vSphere content library, which is a container for VM templates, vApp templates, and other types of files. A content library catalog cannot be shared across VMware Cloud Director instances, as it is specific to a vCenter Server instance3. A shared catalog is a catalog that is shared with other users or organizations within the same VMware Cloud Director installation. A shared catalog cannot be shared across VMware Cloud Director instances, as it is limited to the local installation.

According to the VMware vRealize Operations Install and Configure Guide1, the sizing tool is a web-based application that helps to estimate the required resources and configuration for a vRealize Operations cluster. The sizing tool takes into account various parameters,such as the number and type of objects to be monitored, the number of metrics and properties to be collected, the number of alerts and dashboards to be displayed, the number of users and concurrent sessions, and the desired availability and performance of the cluster.

Two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool are:

• Time Series Data Retention: This parameter specifies the duration for which the collected metrics and properties are stored in the vRealize Operations database. The longer the retention period, the more disk space is required for the cluster nodes. The sizing tool allows the user to select the retention period from 1 month to 12 months, or to enter a custom value.
• Projected Growth: This parameter specifies the expected increase in the number and type of objects to be monitored over time. The higher the projected growth, the more resources are required for the cluster nodes. The sizing tool allows the user to select the projected growth from 0% to 100%, or to enter a custom value.

Therefore, the correct answers are A. Time Series Data Retention and C. Projected Growth, as these are two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool. References:

• 1: VMware vRealize Operations Install and Configure Guide, https://docs.vmware.com/en/vRealize-Operations/8.5/vrealize-operations-manager-85-installation-and-configuration-guide.pdf, page 11-13

In an out-of-box vRealize Operations (vROps) deployment, the internal components' health status can be checked through the Product UI. Specifically, by navigating to the Dashboards section and accessing the vRealize Operations dashboards, an administrator can view various metrics and statuses related to the health and performance of the vROps components. These dashboards are designed to provide a comprehensive overview of the system's health and are a key feature of vROps for monitoring and managing the VMware environment efficiently.

To discover custom application services running on virtual machines, the administrator needs to install the vRealize Operations Service Discovery Management Pack1. This management pack enables service and application discovery using the Service Discovery adapter, which leverages the Telegraf agent to collect data from the end point VMs2. The administrator can configure the Service Discovery adapter to discover predefined and custom applications and services, and view their relationships and metrics in vRealize Operations3. The administrator can also create custom application definitions based on object names, tags, or properties, and import them as XML files. Configuring a white list is not a valid option, as it is used to filter out unwanted services from discovery. References: 1: vRealize Operations Service Discovery Management Pack - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.6/com.vmware.vcom.core.doc/GUID-B9095E9B-7F10-4B2F-95A9-3D54CF5038FF.html)  2: Service and Application Discovery - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.10/com.vmware.vcom.core.doc/GUID-CC683117-D936-432C-B30B-CCCA08E863FB.html)  3: Configure Service and Application Discovery - VMware Docs(https://developer.vmware.com/apis/579/vra-advanced-designer/) : Create Application Definition - VMware Docs : Configure White List - VMware Docs

 The action that would help achieve the goal of excluding alerts triggered by the test/development VMs, but not other VMs, is to create a policy inherited from the current active policy, set the alert definition state to “Disabled”, and then assign to test/development VMs. A policy is a set of configuration settings that define the behavior and appearance of vRealize Operations for the objects to which it is applied1. A policy can be inherited from another policy, and it can override or customize the settings of the parent policy2. An alert definition is a configuration that defines the conditions and actions for generating analert3. An alert definition can be enabled or disabled in a policy, and it can be assigned to specific object types or groups4. By creating a policy inherited from the current active policy, the administrator can preserve the existing settings for the other VMs, and only modify the alert definition state for the test/development VMs. By setting the alert definition state to “Disabled”, the administrator can prevent the alert from being triggered by the test/development VMs, and avoid the unnecessary noise and notifications. By assigning the policy to the test/development VMs, the administrator can apply the customized settings to the desired objects, and ensure the policy precedence and inheritance. Under Alerts, select Alerts Definitions, and then remove the Symptoms Definition (option B) is not a correct action, as it would affect the alert definition for all the VMs, not just the test/development VMs, and it would also remove the ability to detect the CPU usage issue for the other VMs. On the Environment tab, select all test/development VMs, and then unassign the active policy that is currently assigned to the test/development VM (option C) is not a correct action, as it would not disable the alert definition for the test/development VMs, but rather assign them the default policy, which may have different settings and alert definitions than the current active policy. Under Alerts, select Alerts Definitions, and then set the alert definition to “Disabled” for test/development VMs (option D) is not a correct action, as it would not create a separate policy for the test/development VMs, but rather modify the current active policy, which may affect the other VMs that are using the same policy. References:

• Workload Management is a feature of VMware vRealize Operations that enables self-driving operations management for hybrid and multi-cloud environments. It uses artificial intelligence and machine learning to monitor, analyze, and automate the performance, capacity, cost, and configuration of applications, infrastructure, and services12.
• Workload Management allows administrators to set a goal for workload optimization, which defines how vRealize Operations balances the resource utilization across clusters and data centers. The goal can be one of the following options34:
• Workload Management relies on VMware Distributed Resource Scheduler (DRS) and VMware Storage DRS to perform the workload optimization actions. DRS is a feature that automatically balances the compute resources and power consumption across the hosts in a cluster. Storage DRS is a feature that automatically balances the storage resources and I/O load across the datastores in a datastore cluster .
• To enable Workload Management to move a storage resource, such as a virtual disk or a virtual machine, Storage DRS must be enabled for the cluster that contains the storage resource. Storage DRS can be enabled or disabled at the cluster level, and can be configured with different automation levels, such as manual, fully automated, or partially automated .
• If Storage DRS is not enabled for the cluster, Workload Management cannot move the storage resource, as it does not have the permission or the mechanism to do so. This is the underlying reason for the problem. The other options are not relevant for moving a storage resource. DRS is only responsible for moving the compute resources, such as CPU and memory, not the storage resources. Storage DRS can be configured for both intra-datacenter and cross-datacenter migrations, not only for cross-datacenter migrations. The automation level of DRS does not affect the ability of Workload Management to move the storage resource, as long as Storage DRS is enabled.

 To share the custom dashboard with the database admin group and meet the requirements, the administrator can use the options for sharing dashboards in vRealize Operations. The administrator can generate a custom URL of the dashboard, which will allow the database admin group to view the dashboard without authentication. The administrator can also set the expiry period for the link to one week, so that the access to the dashboard will be available only during the mentioned time period. The administrator can then send the database admin team an e-mail that includes the custom URL, so that they can access the dashboard from the e-mail. Alternatively, the administrator can copy the custom URL and share it with the database admin group through other means1. References: 1: Options for Sharing Dashboards - VMware Docs

The cause of this issue is that changes made to scope, time, or potential evidence are not saved after logging out of the vRealize Operations user interface. The troubleshooting workbench feature allows the administrator to perform advanced troubleshooting tasks on an alert or an object by looking for potential evidences of a problem within a specific scope and time range. The administrator can modify the scope, time, or potential evidence in the active session, but these changes are not persistent and are lost when the administrator logs out or closes the browser1. The administrator can see the virtual machine context as a recent search because the recent searches are stored in the browser’s local storage, but the changes made to the troubleshooting workbench are not2.

The other options are not the cause of this issue. Option A is incorrect because the troubleshooting workbench feature is available in all editions of vRealize Operations, and the license edition does not affect the saving of the changes3. Option C is incorrect because there is no Save option when using the troubleshooting workbench, and the administrator cannot save the changes manually1. Option D is incorrect because restoring the vRealize Operations instance from an earlier backup would not affect the changes made to the troubleshooting workbench, as they are not stored in the vRealize Operations database or file system1.

 To estimate the monthly cost of running workloads in IBM Cloud, the administrator can use the What-If Analysis feature of vRealize Operations, which allows forecasting the impact of migrating a workload to a public cloud instance such as AWS, IBM Cloud, Microsoft Azure, Google Cloud or to VMware Cloud on AWS1. The administrator can select the Migration Planning option and choose IBM Cloud as the target cloud provider. Then, the administrator can import the existing VMs that support the business-critical applicationfrom the custom group in vRealize Operations and select all machines to be included in the scenario. Finally, the administrator can run the scenario and get the vRealize Operations analysis and assessment of the plan, which includes the cost and capacity information for the IBM Cloud region2. References: 1: What-If Analysis - Migration Planning: Public Cloud 2: Migration Planning

Continuous Availability (CA) is a feature of vROps that separates the analytics cluster into two fault domains, stretching across vSphere clusters, and protects the analytics cluster against the loss of an entire fault domain. CA requires a witness node to be deployed in the cluster, which acts as a tiebreaker in case of a network partition between the two fault domains. CA ensures that the data stored in the primary node and data nodes in one fault domain is always 100% synced to the replica node and data nodes in the other fault domain. CA is not a disaster recovery solution, but it provides a higher level of availability and data protection than High Availability (HA), which only protects against the loss of a single node. HA creates a replica for the primary node, but does not replicate the data nodes. Therefore, if a whole rack fails, HA may not be able to prevent data loss. Deploying an additional vROps deployment as a standby or configuring remote collector groups are not options that address the requirement of ensuring no monitoring data is lost in the event of a whole rack failure. These options may provide some redundancy or scalability, but they do not guarantee data consistency or availability across fault domains. References: 1: About vRealize Operations Continuous Availability 2: Continuous Availability Considerations 3: About vRealize Operations High Availability 4: High Availability Considerations

 Cost drivers are the expense types used by vRealize Operations to calculate the cost of your private cloud. The total private cloud cost is the sum of cost drivers. Changes that are made to cost drivers are reflected only after the next run of the cost engine1. Cost drivers cover server hardware, storage, licenses, application, maintenance, labor, network, facilities, and additional costs configured within vRealize Operations2. When calculating the monthly cluster costs, vRealize Operations considers the following two types of cost drivers:

• VMware software per socket: This is the cost of VMware licenses based on the number of sockets in the cluster. You can assign different license costs to different clusters depending on the edition and features you use3.
• Storage maintenance as a percentage of hardware costs: This is the cost of maintaining the storage hardware used by the cluster. You can specify the percentage of the storage hardware cost that goes into maintenance. For example, if the storage hardware cost is $10,000 and the maintenance percentage is 10%, the storage maintenance cost is $1,0004. References: 1: Overview of Cost Drivers 2: VM Pricing with vRealize Automation 8.1 and vRealize Operations 8.1 3: License Cost Driver 4: Storage Cost Driver

According to the vRealize Operations User Guide1, Business Intent is a feature that allows the administrator to define the performance, efficiency, and consolidation goals for the clusters and hosts in the SDDC, and to specify the maximum amount of cluster resources to be reserved for burst capacity. Business Intent is applied to objects in vRealize Operations using vCenter Server tags, which are key:value labels that allow operators to add meta-data to vCenter Server objects. By tagging VMs, hosts, and/or clusters with specific tags, the administrator can create business-related placement constraints, such as VMs can only be placed on hosts/clusters with matching tags. For example, the tag OS: Linux can indicate a cluster or VM that is assigned to the category OS with a tag name of Linux. vRealize Operations then uses these tags to optimize the placement and balance of the workloads, and to perform automated remediation actions in the event of an issue. The other options are not correct because:

• Groups are not used to apply Business Intent to objects in vRealize Operations. Groups are collections of objects that share common characteristics, such as type, name, location, or relationship. Groups are used to organize objects for monitoring, analysis, alerting, or policy assignment, but not for workload placement or balance1.
• Policies are not used to apply Business Intent to objects in vRealize Operations. Policies are sets of configuration settings that define how vRealize Operations monitors and manages the objects in the SDDC. Policies are used to enable or disable alerts, metrics, properties, symptoms, recommendations, or actions for different types of objects, but not for workload placement or balance1.
• Roles are not used to apply Business Intent to objects in vRealize Operations. Roles are collections of permissions that define what actions a user can perform on the objects in the SDDC. Roles are used to control the access and visibility of the objects for different users, but not for workload placement or balance1. References: 1: vRealize Operations User Guide, pages 57-59, 62-63, 66-67, 70-71.

 The reason why vRealize Operations reports that the cluster has 0 days remaining when the actual CPU overcommit ratio is less than the 4:1 configured value is that the CPU demand in the cluster is greater than the total CPU capacity. The allocation model is a method of calculating the capacity and utilization of resources based on the amount of resources that are allocated to the objects, such as virtual machines, clusters, or datastores. The allocation model allows the administrator to set the overcommit ratio for CPU, memory, or disk space, which is the ratio of the allocated resources to the available resources. The overcommit ratio determines how much the resources can be overcommitted without affecting the performance or availability of the objects1.

When the administrator enables the allocation model in a policy and sets the CPU overcommit ratio to 4:1 for all vSphere clusters in a vSphere datacenter, it means that the administrator allows the CPU resources to be allocated four times more than the availableCPU resources in the clusters. For example, if a cluster has 100 GHz of CPU capacity, the administrator can allocate up to 400 GHz of CPU resources to the virtual machines in the cluster. However, this does not mean that the virtual machines can consume up to 400 GHz of CPU resources without any impact. The actual CPU consumption of the virtual machines depends on the CPU demand, which is the amount of CPU resources that the virtual machines require to run their workloads. The CPU demand can vary depending on the workload type, intensity, and pattern2.

If the CPU demand in the cluster is greater than the total CPU capacity, it means that the virtual machines are requesting more CPU resources than the cluster can provide. This can result in CPU contention, performance degradation, and SLA violations. In this case, vRealize Operations reports that the cluster has 0 days remaining, which means that the cluster has reached its maximum capacity and cannot accommodate any more CPU demand. The cluster has 0 days remaining even if the actual CPU overcommit ratio is less than the 4:1 configured value, because the overcommit ratio only reflects the allocated resources, not the consumed resources. The overcommit ratio does not guarantee that the cluster can support the CPU demand of the virtual machines, but only indicates the potential capacity of the cluster based on the allocation model1.

The three main categories for reclamation that are available to the administrator in the Reclaim view on the Home Screen navigation are orphaned disks, snapshots, and powered off VMs. The Reclaim view is a feature of vRealize Operations that allows the administrator to identify and reclaim the wasted or unused resources in the environment, such as storage, CPU, and memory1. The Reclaim view shows the potential savings and the actions that can be taken to reclaim the resources for each category. The orphaned disks category shows the virtual disks that are not associated with any virtual machine, and that can be deleted to free up storage space2. The snapshots category shows the snapshots that are older than a specified age, and that can be deleted to free up storage space and improve performance3. The powered off VMs category shows the virtual machines that are powered off for more than a specified period, and that can be deleted or archived to free up storage, CPU, and memory resources4. The unused datastores category (option A) is not a main category for reclamation that is available in the Reclaim view, as it is not a source of wasted or unused resources. The unused datastores are datastores that are not used by any virtual machine or host, and that can be removed from the inventory or assigned to other objects5. The VM disks utilized %10 or less category (option E) is not a main category for reclamation that is available in the Reclaim view, as it is not a source of wasted or unused resources. The VM disks utilized %10 or less are virtual disks that have low utilization, and that can be resized to reduce the allocated storage space6. The unused hosts category (option F) is not a main category for reclamation that is available in the Reclaim view, as it is not a source of wasted or unused resources. The unused hosts are hosts that are not used by any virtual machine or cluster, and that can be removed from the inventory or assigned to other objects. References:

 vRealize Operations provides out-of-the-box compliance packs for various regulatory and standards-based benchmarks, such as PCI, HIPAA, DISA, CIS, and more1. These compliance packs help you assess and report the compliance status of your environment against the best practices and requirements defined by these benchmarks. You can also customize the compliance packs to suit your specific needs or create your own compliance packs2. Among the options given, PCI and HIPAA are the valid out-of-the-box compliance packs available in vRealize Operations. PCI is a compliance pack that helps you ensure the security of cardholder data in your environment3. HIPAA is a compliance pack that helps you protect the privacy and security of health information in your environment. The other options, GDPR, ISO 27017, and FedRAMP, are not out-of-the-box compliance packs in vRealize Operations, although you can create your own compliance packs for them ifneeded. References: 1: Compliance Overview - VMware Docs(https://docs.vmware.com/en/Management-Packs-for-vRealize-Operations/index.html)  2: Compliance Pack Management - VMware Docs(https://docs.vmware.com/en/Management-Packs-for-vRealize-Operations/1.0/Compliance-Pack-for-VMware-Sovereign-Cloud/GUID-3DF17387-8399-444F-BD4B-0F2EA9161532.html)  3: PCI Compliance Pack - VMware Docs(https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/vmware-vrealize-operations-8.2-datasheet.pdf) : HIPAA Compliance Pack - VMware Docs

To enable High Availability (HA) on a vRealize Operations cluster, the following two options are requirements:

• The cluster must have at least one Primary node: The primary node is the first node that is deployed in the cluster and it is responsible for managing the cluster configuration, user interface, and administration functions. The primary node also stores data and performs analytics like any other data node. Without a primary node, the cluster cannot function properly1.
• The cluster must have at least one Data node: A data node is a node that collects data from various sources, stores data in its local file system, and performs analytics and alerting functions. A data node also participates in the cluster load balancing and data replication. To activate HA, you must have at least one data node deployed, in addition to the primary node. This allows the creation of a replica node that can take over the primary node functions in case of a failure2. References: 1: About vRealize Operations High Availability 2: High Availability (HA)

According to the vRealize Operations User Guide1, the two statements that accurately characterize reports in vRealize Operations are:

• A report layout can contain table of contents, cover page, and footer. The report layout defines the appearance and structure of the report, and can include these optional elements to enhance the readability and presentation of the report1.
• Scheduling of reports can be done hourly, daily, weekly, and monthly. The report schedule defines the frequency and time of the report generation, and can be set to run at regular intervals, such as hourly, daily, weekly, or monthly, or at a specific date and time1.

The other statements are not accurate because:

• Views and Dashboards are not the only data types available for a report. A report can also include other data types, such as alerts, events, metrics, properties, and super metrics1.
• Only PDF type reports cannot be used to schedule a report generation. A report can be generated in different formats, such as PDF, CSV, or XML, and any of these formats can be used to schedule a report generation1.
• Reports scheduled for generation can be shared out via email or FTP. A report can be configured to send the generated output to one or more email recipients, or to upload the output to an FTP server1.

vRealize Operations continuous availability (CA) separates the vRealize Operations cluster into two fault domains, stretching across vSphere clusters, and protects the analytics cluster against the loss of an entire fault domain. A fault domain consists of one or more analytics nodes grouped according to their physical location in the data center. To activate CA, you must have at least one data node deployed, in addition to the primary node and the witness node. The primary node and the data node must reside in different fault domains, and the witness node must reside in a third location. Therefore, the minimum number of fault domains required to achieve vRealize Operations continuous availability with a primary node, data node, and witness node is two. References: About vRealize Operations Continuous Availability; Continuous Availability Considerations

According to the VMware vRealize Operations User Guide1, an automated action is a predefined or custom action that can be executed automatically when an alert is triggered. An automated action can help to resolve or prevent the problem that caused the alert, or to notify the relevant stakeholders. To allow an automated action to be triggered from an alert, two conditions must be met:

• Within the active policy, the alert definition’s automated setting must be set to enabled. This allows the alert definition to trigger automated actions when the alert criteria are met. By default, the automated setting is disabled for all alert definitions, and must be manually enabled by the administrator.
• The alert must have a recommendation attached to it. A recommendation is a suggested action that can help to resolve or prevent the problem that triggered the alert. A recommendation can include a link to a related topic in the documentation or an external URL. A recommendation can also be associated with an automated action, which can be executedby the system or by the user. An alert definition can have one or more recommendations, but only one of them can be associated with an automated action.

Therefore, the correct answers are B. Within the active policy, the alert definition’s automated setting must be set to enabled. and E. The alert must have a recommendation attached to it, as these are the two conditions that must be met to allow an automated action to be triggered from an alert. References:

• 1: VMware vRealize Operations User Guide, https://docs.vmware.com/en/vRealize-Operations/8.5/vrealize-operations-manager-85-user-guide.pdf, page 21-22, 25-26, 29-30

 According to the vRealize Operations User Guide1, one of the best ways to quickly identify the underlying problem of slow application VMs is to use the out-of-the-box Performance dashboards that display contention on both VMs and ESXi hosts. These dashboards show the key performance indicators (KPIs) of CPU, memory, disk, and network for the selected objects, and highlight any contention or saturation issues that may affect the performance. The administrator can use these dashboards to drill down into the details of the metrics, alerts, events, and properties of the objects, and isolate the root cause of the problem. The other options are not correct because:

• Under Inventory, selecting Manage Agent, then selecting the VMs, and running Remote Checks on ICMP, HTTP checks is not a helpful action, as it only verifies the connectivity and availability of the VMs, but does not provide any information about the performance or contention of the VMs or the ESXi hosts2.
• Under Report, using Configuration Report - Virtual Machines to list down possible changes that have occurred is not a helpful action, as it only shows the configuration details of the VMs, such as name, UUID, power state, guest OS, CPU, memory, disk, and network, but does not show any performance or contention metrics or alerts of the VMs or the ESXi hosts3.
• Under Administration, choosing Configuration, selecting Object Relationships, and then identifying the VMs and ESXi hosts relationship to generate a correlation of the metric, and finally, isolate the issue is not a helpful action, as it only shows the hierarchical and logical relationships between the objects, such as parent, child, sibling, and peer, but does not show any performance or contention metrics or alerts of the objects4. References: 1: vRealize Operations User Guide, pages 57-59, 62-632: vRealize Operations User Guide, pages 69-703: vRealize Operations User Guide, pages 81-824: vRealize Operations User Guide, pages 84-85.

To achieve the lowest cost in Workload Optimization, the administrator should select the Consolidate option, which will place VMs into as few clusters as possible, but allows for less responsive capacity. This is good for populations with steady demand and may reduce licensing and hardware costs, such as power and cooling1. The Consolidate option is one of the three operational intents that can be selected for Workload Optimization, along with Balance and Moderate2. The Balance option will spread VMs evenly over the available resources, but may move VMs more often. The Moderate option will minimize VM contention, but will not attempt to move VMs to achieve better balance or consolidation1. References: 1: Optimize Performance with VMware vRealize Operations 2: Self-Driving Operations by VMware vRealize Operations Datasheet

• A vRealize Operations support bundle is a collection of log and configuration files that help troubleshoot a vRealize Operations issue. You can create a support bundle from the vRealize Operations UI or from the command line interface (CLI) of the vRealize Operations nodes12.
• If the vRealize Operations UI is inaccessible, you cannot create a support bundle from the UI. Therefore, option C is not a valid process. You need to use the CLI method to create a support bundle from an on-premises deployment3 .
• To create a support bundle from the CLI, you need to log in to the vRealize Operations nodes using SSH and run the generateSupportBundle.py script. This script collects the log and configuration files from the nodes and creates a support bundle in ZIP format. You can then download the support bundle from the /storage/vcops/support directory of the nodes .
• However, you do not need to log in to each vRealize Operations node and run the script separately. You only need to log in to the Primary node and run the script once. The script will automatically collect the files from all the nodes in the cluster and create a single support bundle. Therefore, option A is not a necessary process. You only need to log in to the Primary node and run the script .
• Option B is not a correct process, as it does not use the generateSupportBundle.py script. The /var/log/messages file is not sufficient to gather the correct information for troubleshooting a vRealize Operations issue. You need to use the script to collect all the relevant log and configuration files from the nodes .
• Therefore, the process that will gather the correct information successfully is to log in to the vRealize Operations Primary node using SSH, and then run the generateSupportBundle.py script.This is option D.

The administrator needs the Active Directory domain administrator account and password to configure service discovery to identify which virtual machines are running Active Directory services. Service discovery is a feature of vRealize Operations that allows the administrator to discover and monitor the applications and services running on the virtual machines in the environment1. Service discovery can be performed using two methods: credential-less and credential-based. Credential-less service discovery uses VMware Tools to query the guest operating system for the list of running processes, and then matches them with a predefined set of signatures to identify the applications and services2. Credential-based service discovery uses the credentials provided by the administrator to log in to theguest operating system and run commands or scripts to discover the applications and services3. Credential-less service discovery can be used for most common applications and services, such as web servers, database servers, or file servers, but it has some limitations, such as not being able to discover clustered or distributed applications, or applications that run on non-standard ports4. Credential-based service discovery can be used for more complex and customized applications and services, such as Active Directory, Exchange, or SharePoint, but it requires the administrator to provide the appropriate credentials for each guest operating system. For Windows operating systems, the credentials must be either a local administrator account or a domain administrator account. For Active Directory services, the domain administrator account is preferred, as it has the necessary permissions to access the Active Directory information and configuration. Therefore, the administrator needs the Active Directory domain administrator account and password to configure service discovery to identify which virtual machines are running Active Directory services. No credentials are needed since credential-less service discovery can be used (option A) is not a correct answer, as credential-less service discovery cannot discover Active Directory services, which require credential-based service discovery. Local Windows administrator account and password (option B) is not a correct answer, as the local administrator account may not have the sufficient permissions to access the Active Directory information and configuration, which require the domain administrator account. Active Directory domain user account and password (option D) is not a correct answer, as the domain user account may not have the necessary permissions to access the Active Directory information and configuration, which require the domain administrator account. References:

According to the VMware vRealize Operations Reference Materials, the reason for seeing zero prices for the VMs in the new environment after creating and attaching a pricing card is that the cost calculation has not run yet. The cost calculation is a process that runs every 24 hours by default, and it updates the cost information for all the objects in the inventory based on the assigned pricing cards. Therefore, the administrator needs to wait for the next cost calculation cycle to see the updated prices for the VMs in the new environment. The other options are incorrect because they are either false or irrelevant. The prices are not only available for ESXi hosts, but for any object that has a pricing card attached. A cost-based pricing card can be used to calculate the cost of an object based on its actual resource consumption, and it does not result in zero prices. The pricing card was attached to the VM resource, otherwise the administrator would not see the pricing card name in the cost dashboard. References: Pricing Overview; Cost Calculation; Create a Pricing Card

The type of node that should be deployed to monitor a remote datacenter using an existing vRealize Operations Manager cluster is a Remote Collector node. A Remote Collector node is a node that is deployed in a remote datacenter location across a firewall, and collects data from the remote objects without performing analysis or storing data. A Remote Collector node can reduce the bandwidth consumption and the load on the vRealize Operations analytics cluster, and can also navigate firewalls and interface with remote data sources12. A Remote Collector node can be deployed on a different operating system than the rest of the cluster, and can support a round-trip time (RTT) of up to 200 ms3.

The other options are not correct, because they are not suitable for monitoring a remote datacenter with a high RTT. A Replica node is a node that is converted from a Data node to provide high availability (HA) or continuous availability (CA) for the vRealize Operations cluster. A Replica node is a copy of the Primary node, and must be deployed in the same datacenter as the Primary node1. A Data node is a node that performs data collection and analysis for the vRealize Operations cluster, and can be added to scale out the cluster capacity and performance. A Data node must be deployed in the same datacenter as the Primary node, and can support a RTT of up to 10 ms1. A Witness node is a node that is required for continuous availability (CA) of the vRealize Operations cluster, and acts as a decision maker in case of a network partition between two fault domains. A Witness node must be deployed in a third datacenter that is separate from the two fault domains, and can support a RTT of up to 100 ms1.

A cloud account in vRealize Operations is a configuration that enables data collection from a cloud platform or service. vRealize Operations supports various cloud account types, such as vCenter Server, AWS, Azure, Google Cloud Platform, VMware Cloud on AWS, and VMware Cloud on Dell EMC1. VMware Cloud on AWS is a cloud account type that allows you to monitor and manage your VMware Cloud on AWS SDDC resources, such as hosts, clusters, datastores, and virtual machines2. NSX-T and NSX-V are not cloud account types, but network and security solutions that can be integrated with vRealize Operations3 . References: 1: Cloud Accounts in vRealize Operations 2: Configure a VMware Cloud on AWS Cloud Account in vRealize Operations 3: Configure an NSX-T Cloud Account in vRealize Operations : [Configure an NSX-V Cloud Account in vRealize Operations]

Removing the corrupted node, and then disabling and re-enabling vRealize Operations Manager High Availability to reassign the primary replica role to another existing node in the cluster is the correct way to resolve the availability issue within vRealize Operations Manager. This method ensures that the cluster can continue to operate with high availability and continuous availability, as the primary replica node is responsible for providing critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. By removing the corrupted node, the administrator can prevent any further issues or conflicts with the cluster configuration. By disabling and re-enabling vRealize Operations Manager High Availability, the administrator can trigger the cluster to select a new primary replica node from the existing data nodes, and synchronize the data and services with the primary node. Deploying a new vRealize Operations Manager node, and then adding it to the existing cluster is not a valid option, as it does not address the primary replica role assignment, and may cause additional problems with the cluster configuration. Cloning an existing primary vRealize Operations Manager node, and then adding it into the vRealize Operations Manager cluster is not a feasible option, as it may result in duplicate node IDs, IP addresses, and hostnames, and may cause conflicts with the cluster configuration. Asking the backup administrator to restore the corrupted primary replica node, and then refreshing the nodes from thevRealize Operations Manager administrator interface is not a reliable option, as it may take a long time to restore the node, and may not guarantee the consistency and integrity of the data and services on the node. References: Remove a Node from a Cluster, section “Remove a Node from a Cluster”. About vRealize Operations Cluster Nodes, section “About vRealize Operations Cluster Nodes”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

According to the VMware vRealize Operations Reference Materials, Workload Optimization is a feature that allows you to automatically balance and optimize workloads across your virtualized infrastructure. Workload Optimization has four settings that determine how aggressively it moves workloads between clusters: Moderate, Balance, Consolidate, and Buffer. Each setting has a different impact on the number of vMotion operations, the cluster headroom, and the workload contention.

The Consolidate setting is the most aggressive setting that aims to minimize the workload contention across clusters by reducing the number of clusters used and maximizing the utilization of each cluster. The Consolidate setting performs the most vMotion operations, leaves the least cluster headroom, and has the lowest workload contention. The Consolidate setting is suitable for environments that have overprovisioned clusters and want to free up some clusters for other purposes or reduce the infrastructure costs. Therefore, option C is correct.

The other options are not correct because they do not meet the goal of minimizing the workload contention across clusters by reducing vMotion operations. Option A is not correct because the Moderate setting is the least aggressive setting that aims to maintain the current state of the clusters and avoid unnecessary vMotion operations. The Moderate setting performs the least vMotion operations, leaves the most cluster headroom, and has the highest workload contention. The Moderate setting is suitable for environments that have stable clusters and do not want to disrupt the existing workload placement. Option B is not correct because the Balance setting is a moderate setting that aims to balance the workload distribution across clusters and improve the performance of the clusters. The Balance setting performs a moderate number of vMotion operations, leaves a moderate cluster headroom, and has a moderate workload contention. The Balance setting is suitable for environments that have some imbalanced clusters and want to optimize the workload placement. Option D is not correct because the Buffer setting is a conservative setting that aims to create more cluster headroom and reduce the risk of resource shortage. The Buffer setting performs a low number of vMotion operations, leaves a high cluster headroom, and has a low workload contention. The Buffer setting is suitable for environments that have unpredictable or bursty workloads and want to ensure enough capacity for future demand. References:

Expected Utilization is the workload option that should be included in the scenario to simulate 25% utilization of the resources. Expected Utilization is a percentage value that indicates how much of the allocated resources (CPU, memory, and storage) are expected to be used by the workload. By setting the Expected Utilization to 25%, the administrator can model the impact of adding or removing a workload that consumes 25% of the resources in the datacenter. Memory, Annual Projected Growth, and CPU are not workload options, but workload attributes. Memory and CPU are the amount of resources allocated to the workload, and Annual Projected Growth is the percentage by which the workload is expected to grow each year. These attributes do not directly specify the utilization of the resources by the workload. References: What-If Analysis - Workload Planning: Traditional, section “How What-If Analysis - Workload Planning: Traditional Works”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

According to the vRealize Operations User Guide1, the Business Intent option allows the administrator to configure vRealize Operations to ensure that workload performanceacross the VMware SDDC is the main priority. The Business Intent option enables the administrator to define the performance, efficiency, and consolidation goals for the clusters and hosts in the SDDC, and to specify the maximum amount of cluster resources to be reserved for burst capacity. The vRealize Operations then uses these goals to optimize the placement and balance of the workloads, and to perform automated remediation actions in the event of an issue. The other options are not correct because:

• The Reclamation option allows the administrator to configure vRealize Operations to identify and reclaim unused or overprovisioned resources in the SDDC, such as CPU, memory, disk space, and snapshots. This option does not directly affect the workload performance or remediation activities1.
• The Operational Intent option allows the administrator to configure vRealize Operations to monitor and alert on the operational health and risk of the SDDC components, such as clusters, hosts, datastores, and virtual machines. This option does not directly affect the workload placement, balance, or remediation activities1.
• The Rightsizing option allows the administrator to configure vRealize Operations to analyze and recommend the optimal CPU, memory, and disk size for the virtual machines in the SDDC, based on their actual utilization and demand. This option does not directly affect the workload performance or remediation activities1. References: 1: vRealize Operations User Guide, pages 63-66.
