NCP-MCA Nutanix Certified Professional - Multicloud Automation (NCP-MCA) v6.5 Exam Questions and Answers

An X-Play Trigger is a condition that initiates a Playbook. There are four types of X-Play Triggers: Alert, Audit, Event, and Time1. An Alert Trigger is based on a Prism alert, such as a VM power state change or a disk failure. An Audit Trigger is based on a Prism audit entry, such as a user login or a cluster operation. An Event Trigger is based on a Prism event, such as a VM creation or deletion. A Time Trigger is based on a schedule, such as daily, weekly, or monthly2. In this scenario, the administrator needs to create a Playbook to be notified when VMs are deleted. Therefore, the appropriate X-Play Trigger would be an Event Trigger, since VM deletion is a Prism event. References: 1: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 42: Getting Started with Nutanix X-Play – Nutanix.dev

To update the running configuration for a multi-VM application in AWS using the Manage tab for the application in Calm, the administrator needs to provide the provider information for the AWS account. This includes the access key, secret key, region, and VPC ID. If the provider information is missing, the administrator will not be able to perform any actions on theapplication from Calm. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 16, section 4.1.1. 

 The easiest way to satisfy the request is to add an Email action to the end of the existing playbook and use the {{action[index] .stdout}} parameter in the Message field. This way, the administrator does not need to modify the script or create a file to store the output. The {{action[index] .stdout}} parameter will capture the standard output of the previous action, which is the VM SSH action that executes the script. The Email action will then send the output as the message body to the specified recipients. References: You can find more information about this topic in the following sources:

Autopilot is a feature of Nutanix Calm that allows the administrator to automate the execution of playbooks based on predefined conditions or triggers. Autopilot can optimizethe performance, availability, and cost of applications by applying the appropriate actions in response to events or metrics. Before configuring autopilot, the administrator must be aware of the following limitations12:

• Autopilot never waits for approvals. This means that the administrator must ensure that the playbooks are tested and verified before enabling autopilot. Autopilot will execute the playbooks without any human intervention or confirmation.
• Autopilot feature only applies to metric-based alerts as triggers. This means that the administrator can only use metrics from the Nutanix Prism Central or the Nutanix Karbon clusters as the conditions for triggering the playbooks. Autopilot does not support other types of triggers such as schedules, webhooks, or manual triggers. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 10; Nutanix Calm SaaS User Guide, section 4.3.

To automate the creation of a new user in GitLab for every new development environment, the administrator should perform the following tasks within a Calm blueprint:

• Create an HTTP pre-create task to create the user in GitLab via REST API. This task will send an HTTP request to the GitLab server with the user information and credentials, and receive a response with the user ID and status. The administrator can use the response to verify the user creation and store the user ID as a variable for later use.
• Create runtime-editable variables for user and password in the blueprint. These variables will allow the administrator to specify the user name and password for the new GitLab user at the time of launching the blueprint. The variables can be passed as parameters to the HTTP pre-create task and used in the REST API call.
• The other two options are not correct because:

The PagerDuty Integration service allows you to create and manage incidents in PagerDuty based on events in Nutanix X-Play. To configure the PagerDuty Integration service, you need to provide the following information:

• Service Name: The name of the PagerDuty service that you want to integrate with X-Play.
• API Key: The API key generated from the PagerDuty service settings.
• Plays: The plays that you want to trigger incidents in PagerDuty. You can select one or more plays from the list of available plays in X-Play. You can also specify the incident priority, escalation policy, and alert details for each play.
• Alert Grouping: (Optional) The alert grouping strategy that you want to use for the PagerDuty incidents. You can choose from the following options:

A Developer permission level grants access to create, update, delete, and duplicate blueprints in Nutanix Calm12. A Developer can also launch, manage, and delete applications from blueprints, as well as create, update, delete, and duplicate runbooks2. A Consumer can only launch and manage applications from blueprints, but cannot modify them2. An Operator can launch, manage, and delete applications from blueprints, as well as run and manage runbooks, but cannot create or modify them2. A Domain Admin can perform all the actions of a Developer and an Operator, as well as manage projects, categories, and endpoints2. References:

• Nutanix Multicloud Automation Administration (NMCAA)

The Restart Action of a Service allows the developer to define custom tasks that will be executed when the service is restarted. An Execute Task can run any script or command on the target VM, such as restarting the IIS service. This way, the Operator can use the Self-Service Portal to restart the service without logging into the VM or using another tool.

A Branch Condition is a type of action in X-Play that allows you to create conditional logic based on the output of a previous action or a custom expression. A Branch Condition can have multiple branches, each with a different condition and a different set of actions to execute if the condition is met. The minimum number of actions required in a Branch Condition is two: one for the condition itself, and one for the action to perform if the condition is true. If the condition is false, the Branch Condition will skip to the next action in the Playbook. You can add more branches to a Branch Condition, but you cannot have less than two. References: Nutanix Calm: Playbooks - Read the Docs and Nutanix Calm: Branch Condition - Read the Docs.

The administrator should modify the alert by adding the correct category and assign the category Environment:Development to development VMs. By doing this, they can filter out alerts for development VMs that are expected to have memory constrained alertsand focus on those that are critical, such as production VMs. This is based on the general practices in managing alerts in a multicloud environment, as well as the specific features and requirements of Nutanix Calm and Prism Central. References:

A Playbook action has a default memory limit of 256 MB, which can be increased up to 1024 MB in the advanced settings of the action. If the action requires more memory than the limit, it will fail with the error message “Internal Error, Maximum Memory size limit reached”. To resolve this issue, the administrator can edit the action and increase the memory limit to a suitable value, depending on the complexity and requirements of the action.

Substrates are the components of a blueprint that define the cloud resources and configurations for deploying VMs or applications. Substrates can be associated with different cloud accounts, such as AWS, Azure, GCP, or Nutanix, to enable multicloud deployments. By using substrates, an administrator can create a blueprint that can deploy VMs to multiple clouds, depending on the availability, cost, or performance requirements.

• Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, Section 2.1: Create a blueprint to deploy infrastructure and applications using Nutanix Calm2

Scaling VM replica settings allow you to specify the minimum, maximum, and default number of VMs that can be created from a blueprint service. The minimum and default values must be equal to or greater than the number of VMs needed at any time and at time of deployment, which is 2 in this case. The maximum value must be equal to or less than the project quota divided by the VM resources, which is 100/12 = 8 for vCPUs and 300/24 = 12 for memory. The lowest of these two values is the limit for the maximum value, which is 8. Therefore, the only option that meets all the requirements is B. MIN: 2, MAX: 7, Default: 2.

The Calm Marketplace acts as an application store, providing end users with a catalog of available applications. By default, Calm comes pre-seeded with validated Blueprints for multiple open source and enterprise applications. These are the set of pre-seeded application Blueprints. Additionally, Marketplace Manager acts as a staging area for publishing default and user-created Blueprints to your local Marketplace. These are the published and versioned Blueprints. The other two options, library of executable tasks and store of all Blueprints created in Calm, are not features of the Calm Marketplace. References: Calm: Marketplace - Read the Docs and Calm: Marketplace - Read the Docs

To effectively automate the scaling of the environment, the administrator needs to know the steady state resource utilization and the expected resource utilization under load of the application, database, and web VMs. These two pieces of information will help the administrator to define the scaling policies, thresholds, and actions for the blueprint service that deploys the infrastructure. The administrator can use the Self-Service feature of Nutanix Multicloud Automation to create a blueprint service that can scale up or down based on the resource utilization metrics. The administrator can also use the Runbook feature to automate the scaling actions using scripts or APIs.

The other options are incorrect because:

• SLA uptime of the application: This is not a piece of information that is needed to automate the scaling of the environment. The SLA uptime of the application is a performance indicator that measures the availability and reliability of the application. The administrator can use the X-Play feature of Nutanix Multicloud Automation to create event-driven playbooks that can trigger actions based on alerts or schedules to ensure the SLA uptime of the application.
• If the application needs to be highly available: This is not a piece of information that is needed to automate the scaling of the environment. The high availability of the application is a design consideration that affects the architecture and configuration of the infrastructure and the application. The administrator can use the Projects feature of Nutanix Multicloud Automation to create projects that can define the availability domains, networks, and storage for the infrastructure and the application.

Nutanix provides a documented process to seed Github based scripts into the Calm Task Library, which allows users to import and use custom tasks from the Nutanix public Github repository or any other Github repository. This process is described in the Nutanix Calm DSL User Guide and the Nutanix Calm DSL Tutorial.

Nutanix also publishes official vetted blueprints and tasks to Nutanix’s public Github Calm repository, which is located at https://github.com/nutanix/blueprints . These blueprints and tasks are created and maintained by Nutanix engineers and can be used as reference or templates for building Calm applications. Some examples of these blueprints and tasks are:

• Kubernetes Cluster: A blueprint that deploys a Kubernetes cluster on Nutanix AHV using Calm.
• MySQL HA: A blueprint that deploys a MySQL cluster with high availability on Nutanix AHV using Calm.
• Windows Server: A blueprint that deploys a Windows Server 2019 VM on Nutanix AHV using Calm.
• [Install Python]: A task that installs Python on a Linux VM using Calm.

Calm’s public repository does not contain Nutanix-vetted custom scripts created and published by community members. These scripts are hosted in a separate repository called [Automation], which is a centralized repo for community driven Nutanix automation. These scripts are not officially supported or endorsed by Nutanix and may not be compatible with the latest versions of Calm or Nutanix products.

Nutanix does not provide documented processes to seed scripts from any source repository. Users can only import scripts from Github repositories using the Calm Task Library. Other source repositories are not supported by Calm.

According to the Nutanix Prism Central Guide1, categories are key-value pairs that can be assigned to entities such as VMs, images, blueprints, etc. Categories can be used tofilter, group, and manage entities based on their attributes. To review and clean up all existing categories within the Nutanix environment, the administrator should filter on the name, value, entities, and policies of the categories. The name and value of the categories identify the category type and the category value respectively. The entities show how many and which entities are assigned to the category. The policies show how many and which policies are associated with the category. By filtering on these information, the administrator can organize the findings and eliminate unused categories. References:

• 1 Nutanix Prism Central Guide: Categories2

The Task Library is a centralized repository of tasks that can be reused across multiple blueprints. The administrator can publish a task to the Task Library by clicking on the Publish icon in the task editor. The task will then be available in the Task Library tab under the Tasks section in the Calm UI. The administrator can select the task from the TaskLibrary and drag and drop it into another blueprint. This way, the administrator can reuse the task with the least amount of effort.

According to the Nutanix Calm Administration Guide1, the minimum system requirements for Prism Central are 32 GB of RAM and 8 vCPUs. If the production Prism Central has less than the minimum RAM, it may affect the performance of Calm and other services running on Prism Cen

The administrator should use a trigger based on an event when creating a playbook to automate the scaling of the VDI solution. An event trigger is a type of trigger that executes a playbook when a specific event occurs in the Nutanix environment or in a third-party system. An event trigger can be configured to listen to events from various sources, such as Prism alerts, Calm actions, or external webhooks. In this scenario, the administrator can use an event trigger to listen to the webhook from the third-party monitoring tool and execute a playbook that creates additional resources and adds them to the VDI solution.

A trigger based on a REST API is not the best option, because it requires the administrator to manually invoke the playbook using an API call. This is not as efficient or reliable as using an event trigger that automatically executes the playbook when the capacity threshold is reached.

A trigger based on an email is also not the best option, because it requires the administrator to configure an email server and a mailbox to receive the notification from the third-party tool. This adds complexity and overhead to the automation process and may not be as secure or timely as using an event trigger.

A trigger based on an alert is a valid option, but it depends on the availability and compatibility of the Prism alert system with the third-party tool. If the third-party tool can send alerts to Prism, then the administrator can use an alert trigger to execute the playbook. However, if the third-party tool does not integrate with Prism, then the administrator cannot use an alert trigger and has to use an event trigger instead.

According to the Nutanix Multicloud Automation Administration (NMCAA) course1, one of the prerequisites for using X-Play to automate tasks on VMs is to have SSH enabled and configured on the target VMs. This allows X-Play to connect to the VMs and execute commands or scripts remotely. If the SSH service is not running on the VMs, then X-Play will fail to connect and perform the actions, resulting in the error message shown in the exhibit. The other options are not likely to cause this error, as they are either unrelated to X-Play (A and B) or not required for X-Play to work ©. References: Nutanix Multicloud Automation Administration (NMCAA) course

A Playbook is a feature of Nutanix Calm that allows you to automate tasks based on certain triggers or events. You can use a Playbook to create a workflow that monitors the storage capacity of the cluster and sends an email notification to the IT Director when the capacity reaches a certain threshold. You can also use the Playbook to generate a forecast report that shows the projected storage usage and availability based on historical data and trends.

Test Script is a feature of Nutanix Cloud Manager (NCM) Self-Service that allows users to test or validate scripts before deployment. Test Script enables users to run scripts on a VM without creating a blueprint or a runbook. Users can select a VM, choose a script type, enter the script content, and execute the script. The output of the script is displayed in the Test Script window. Test Script can be used to troubleshoot errors, verify functionality, or preview the results of a script before using it in a blueprint or a runbook. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 14, section 3.1. Nutanix Multicloud Automation Administration (NMCAA) course, module 3, lesson 4. Validate Your Nutanix Cloud Manager Self-Service Skills + Access Special Offer.

The image is unavailable for deployment on the cluster because the cluster and the image do not have the proper categories assigned for the placement policy. A placement policy is a set of rules that determines which clusters and images are available for VM deployment based on the categories and values assigned to them. If the cluster and the image do not match the placement policy criteria, they will not be shown as options for VM deployment. Therefore, the administrator needs to assign the appropriate categories and values to the cluster and the image to make them compatible with the placement policy. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 12; Nutanix NCP-MCA Questions, question 111.

 The alert in Prism Central indicates that Calm showback is not able to reach the beam service. This could be due to network connectivity issues or incorrect configurations. The administrator should check the DNS configuration in Prism Central (Option A) to ensure that it is correctly configured to allow communication with the Beam service. Additionally, checking if Prism Element is configured with Proxy settings (Option C) is essential as it can also affect the communication between Calm and Beam. Pulse (Option B) and Flow (Option D) are not related to the Calm showback feature and do not impact its functionality.

An event trigger is a type of trigger that can be used to execute a playbook when a specific event occurs in the Nutanix platform. An event trigger can be configured with various parameters, such as the event type, the target VM, the target VM category, the target project, and the target user. In this scenario, the administrator wants to be notified when a subset of VMs within the Environment:Dev category is restored from snapshot. Therefore, the event trigger should have the following parameters:

• Event type: Snapshot Restoration. This is the event that indicates a VM has been restored from a snapshot.
• Target VM: VMS in Environment: Dev. This is the filter that specifies which VMs are relevant for the trigger. By selecting VMS in Environment: Dev, the trigger will only apply to the VMs that belong to the Environment:Dev category.
• Other parameters: These can be left as default or customized as needed.

The Plays dashboard in Prism Central provides a centralized view of all the Playbooks that have been executed across the clusters registered with Prism Central. It shows the status, duration, and output of each Playbook run, as well as the details of the triggers, targets, and actions involved. An administrator can use the Plays dashboard to troubleshoot why a Playbook failed to grow the memory of a VM by checking the error messages, logs, and output of the Playbook run. The other options are not the correct places to check for Playbook failures, as they do not provide the same level of information and visibility as the Plays dashboard. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) v6.5, Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6 Exam, Nutanix Exam NCP-MCA Topic 4 Question 20 Discussion

The error message indicates that the script failed to authenticate to the remote server using CredSSP. CredSSP is a security mechanism that allows a client to delegate its credentials to a remote server for authentication. To use CredSSP, both the client and the server need to enable it and configure the role and the trusted hosts. The command Enable-WSManCredSSP -Role Client enables CredSSP on the client side and specifies the remote server as a trusted host. This command should be added to the script before invoking the Invoke-Command cmdlet that runs the script block on the remote server. The other commands are either irrelevant or incorrect for this scenario. References: Nutanix Calm: PowerShell Scripts - Read the Docs and Enable-WSManCredSSP (Microsoft.PowerShell.Management) - PowerShell | Microsoft Docs.

To enable scaling for a blueprint, the developer needs to add scaling actions to the application profile. Scaling actions are scripts that define how to scale out (add more instances) or scale in(remove instances) of an application tier. The developer can also specify the minimum and maximum number of instances allowed for each tier, and the scaling policy (manual or automatic) based on metrics or schedules. The developer can access the application profile from the Blueprint Editor by clicking on the application name and then selecting the Actions tab. References: Nutanix Multicloud Automation Administration (NMCAA) course, Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Guide, [Nutanix Calm User Guide]

You can upgrade Nutanix Calm or Epsilon (the orchestration engine used by Nutanix Calm) by using the Life Cycle Manager (LCM) from the Prism Central. LCM allows you to upgrade Calm or Epsilon independently or simultaneously. You can also select the version that you want to upgrade to and perform the update from the Options list. For more information, see the Nutanix Calm Upgrades section in the Nutanix Calm Admin and Operations Guide1 and the Performing Inventory and Upgrading Calm with Life Cycle Manager article2. References:

The administrator needs to add AWS as a provider in Calm. A provider is a cloud platform or infrastructure that hosts the application VMs or services. Calm supports various providers such as Nutanix, AWS, Azure, GCP, VMware, and Kubernetes. To add a provider, the administrator needs to go to the Providers page in the Calm UI and click on the +Create Provider button. Then, the administrator needs to select the AWS provider type and enter the required information such as name, access key, secret key, and regions. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) Exam Blueprint Guide, page 11; Nutanix Calm User Guide, section 3.1.

The most optimal way to correct the failed deployment is to retry the failed deployment. This option allows the administrator to resume the deployment from the point of failure, without having to redeploy the entire application or create a new runbook. Retrying the failed deployment also preserves the application state and configuration, and avoids creating duplicate resources or conflicts.

Redeploying the application is not the best option, because it requires the administrator to delete the existing application and launch a new one from scratch. This option wastes time and resources, and may result in data loss or inconsistency.

Creating a runbook to retry is also not the best option, because it requires the administrator to write a custom script or workflow to handle the retry logic. This option adds complexity and overhead to the automation process, and may not be compatible with the original blueprint or application.

Rewriting the blueprint to have error handling is a valid option, but it is not the most optimal one. This option requires the administrator to modify the blueprint code and add logic to handle different types of errors and exceptions. This option improves the robustness and reliability of the blueprint, but it does not correct the failed deployment itself. The administrator still has to redeploy the application or retry the failed deployment after rewriting the blueprint.

A playbook REST API action allows the administrator to send an HTTP request to a specified endpoint, such as the Prism Central API, to perform an operation, such as deleting a VM. A playbook webhook action allows the administrator to send a payload to a specified URL, such as a ServiceNow webhook, to trigger an event, such as an approval flow. Both of these actions can be used to automate the deletion of VMs from a ServiceNow approval flow, where the developers can request and confirm the removal of their environments. A playbook webhook trigger and a playbook REST API trigger are not valid options, as they are used to initiate a playbook based on an external event, not to perform an action within a playbook. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Blueprint Guide, page 10; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 4; NCP-MCA Exam Dumps - Nutanix Certified Professional - Multicloud …, question 70.

 The Developer role is the most appropriate role for the end user who needs to modify the blueprints for the project. The Developer role allows the user to create, edit, and delete blueprints and runbooks within the project, as well as launch and manage applications from the Marketplace. The Developer role does not have the privileges to create or manage projects, users, roles, or categories, which are reserved for the Project Admin role. The Consumer role only allows the user to launch and manage applications from the Marketplace, but not to modify the blueprints or runbooks. The Operator role allows the user to monitor and manage the infrastructure and applications within the project, but not to create or edit the blueprints or runbooks.
