2V0-16.25 VMware vSphere Foundation 9.0 Administrator Questions and Answers

VMware vSphere Foundation (VVF) integrates VMware Aria Operations (vRealize Operations) for intelligent operations management, enabling automated reporting to minimize operational overhead. To meet the requirements for a weekly health status overview including cluster health, storage usage, and VM growth trends, an administrator must first create a custom View in Aria Operations to define the specific KPIs (e.g., cluster availability, datastore capacity, and VM count trends over time). This View is then added to a new Report Template, which compiles the data into a structured report format like PDF or CSV. Next, the scheduler in Aria Operations is configured to generate and email the report every Monday morning, ensuring delivery without manual intervention. This approach leverages built-in automation for recurring tasks, reducing effort compared to ad-hoc exports or manual configurations.

Other options do not fully satisfy the requirements: Option A creates a dashboard for interactive visualization but not a scheduled report; Option C uses a built-in report with limited customization and no direct FTP export or scheduling; Option E involves manual CSV exports from Metrics Explorer, increasing overhead and lacking automation.

InVCF Operations, alerts can be configured withnotification settings. To ensure onlyrelevant stakeholdersreceive alerts:

You assignspecific recipientsto notifications.

This avoids alert fatigue and ensures teams only see alerts they are responsible for.

Other options:

A. Write to file→ Not for stakeholder notifications.

B. Only critical alerts→ Reduces volume, but still not targeted to relevant recipients.

D. Generic contact info→ Sends to broad groups, not selective.

To ensurecompromised users cannot access vCenter resources:

Assign theNo Accessrole at the vCenter level.

Enable propagationso this restriction applies to all child objects.

This guaranteeszero permissionsfor SUSPECT_USERS.

Other options:

B. Administrator with uncheck propagate→ Still gives dangerous access at root level.

C. Disconnect Active Directory→ Disrupts all AD users, not just suspect ones.

D. Read-only role→ Still grants access, not acceptable during investigation.

TheVM Storage Policy rulethat controlsdata redundancy in vSANisFailures to Tolerate (FTT).

Defines the number of hardware failures (host, disk, network) that vSAN can tolerate while maintaining data availability.

Configurations includeRAID-1 (mirroring),RAID-5/6 (erasure coding).

Other options:

B. Disk Stripes Per Object→ Defines performance striping, not redundancy.

C. Stripe Width→ Same as above, not redundancy.

D. Flash Read Cache Reservation→ Relates to caching performance, not redundancy.

To supportcontainerized workloads within VMware vSphere Foundation (VVF), the essential component isvSphere Kubernetes Service (vSphere with Tanzu).

Provides nativeKubernetes integrationwith vSphere clusters.

Enables runningPods, Tanzu Kubernetes clusters, and containerized workloadson vSphere infrastructure.

Other options:

VCF Automation (A):Automates VCF lifecycle but not containers.

VCF Fleet Manager (B):Manages multi-instance environments, not workload containers.

VCF Operations (C):Provides monitoring/analytics but not container runtime.

The workload requirements specify:

High-performance application

Latency-dependent workloads

Compute and storage must reside in the vSAN cluster

The correct option isvSAN Express Storage Architecture (ESA)because:

ESA is designed forhigh-performance, low-latency applications.

It leveragesNVMe-based storage devicesand25GbE networking, delivering better IOPS and reduced latency compared to OSA.

OSA(Original Storage Architecture) is older and less efficient.

OSA Stretched Cluster(A) is for resilience across sites, not specifically performance.

vSAN Storage Cluster (B)is a generic term and not specific.

Thet-shirt sizing model(Small, Medium, Large) forvCPU allocationis an example ofslab-based pricing.

Base rate slabsallow administrators to define different ranges (slabs) of resource usage with associated rates.

In this case, vCPUs are grouped into ranges (1–2, 3–4, 5–8), and charges are applied per slab.

Other options:

A. Base rate storage per GB→ Applies to storage, not CPU.

C. Base rate CPU per GHz→ Charges by GHz usage, not vCPU count.

D. Base rate CPU per vCPU→ Flat per vCPU, no slab/tier-based flexibility.

In this scenario, anetwork failureoccurred on a host, and VMs on that host didnot restart on other hosts, even thoughHA and DRS were enabled.

This indicates thatvSphere HA detected an isolation event(the host lost network connectivity) but tookno action, because theHost Isolation Response was disabled.

Normally, with Host Isolation Response set to "Power Off and Restart VMs," HA restarts affected VMs on surviving hosts.

Since powering off a host manually triggers a restart correctly, the failure here was specific toisolation behavior.

Other options:

B. Affinity rule "should run on"→ Would still allow HA restart elsewhere if isolation occurred.

C. DRS not enabled→ DRS only balances load; HA is responsible for restarts.

D. HA not enabled→ Contradicts the scenario (HA was enabled).

After successfully deploying theVCF Installer appliance, and ensuring ESXi hosts are powered on and meet prerequisites, thenext stepis to:

Launch the VCF Installer deployment wizard, which guides administrators through host onboarding, vCenter deployment, and cluster setup forvSphere Foundation.

Other options:

A. Enable SSH on all ESX hosts→ Not required unless troubleshooting.

C. Install SDDC Manager using VCF Installer→ Only applies to full Cloud Foundation, not vSphere Foundation deployment.

D. Manually deploy vCenter Server Appliance→ The Installer wizard automates this.

To move a VM to another cluster:

Requirement: Zero downtime→ RequiresvMotion.

Challenge: Datastore not shared→ RequiresStorage vMotion.

The combined operation,Cross-Cluster vMotion with Storage vMotion, allows moving compute and storage at the same time, with no downtime.

Other options:

A. vMotion only→ Requires shared datastore, not available here.

B. Backup/restore→ Causes downtime, not acceptable.

D. Cannot be moved→ Incorrect; vMotion + Storage vMotion supports this.

InVCF Operations for Logs(formerly vRealize Log Insight):

ThePrimary Nodeis responsible forcoordinating the overall functioning of the cluster, including configuration management and directing traffic.

Worker/Data Nodeshandle log ingestion and query execution.

Replica Nodeprovides HA for the Primary Node but does not act as the main coordinator.

ForiSCSI multipathing with ALUAandhigh performancein ESXi:

1 vSwitch with 2 Uplinks→ Standard design for redundancy and multipathing. (B)

Add iSCSI software adapter→ Required to connect to storage. (E)

Configure two bound VMkernel ports→ Ensures multipathing (one per uplink). (G)

Set PSP to Round Robin (RR)→ Optimizes I/O balancing across multiple paths. (F)

Other options:

A. 2 vSwitches with 1 Uplink each→ Not recommended, complicates multipathing.

C. NVMe over TCP→ Not relevant, storage is iSCSI.

D. MRU policy→ Legacy, not high performance.

H. Unbound VMkernel ports→ Used for software iSCSI port binding, but "bound" VMkernel ports are required for multipathing.

TheVCF Operations for Logs capabilitymost useful forroot cause analysis and troubleshootingisLog Querying.

Allows searching, filtering, and correlating log events to diagnose issues.

Log Forwarding (A)→ Sends logs elsewhere, not analysis.

Alerting (B)→ Notifies about issues but does not provide investigation details.

Dashboarding (C)→ Provides visualization, but root cause analysis requiresqueries.

The administrator wants toproactively manage performance degradationduring peak times without overwhelming the IT team.

The correct method is tocreate a custom alert with specific metric, threshold, and duration(A).

This ensures alerts are triggered only when sustained performance issues occur, reducing noise.

B. Default alert settings→ Too generic, may cause alert storms.

C. Custom dashboard→ Useful for visualization but not proactive alerting.

D. Notify during off-peak hours→ Defers the issue, not proactive.

The scenario:

Remote sitewith 2 ESXi servers, 1GbE networking only.

Storage system supports both network (NAS/iSCSI/NFS) and Fiber Channel.

Fiber Channel is not feasible (no FC switches/HBAs).

vSAN requires more than 2 nodes (minimum 3 for standard vSAN, 2+Witness for 2-node), not mentioned here.

The most suitable solution:

UseNFS storage over 1GbE. (D)

Provides shared storage accessible to both ESXi hosts.

Other options:

A. vSAN→ Needs 3+ nodes or a witness, not supported in this config.

B. Local storage→ Not shared, fails HA/DRS requirements.

C. Fiber Channel→ Requires HBAs and FC switch, not available.
