2V0-16.25 VMware vSphere Foundation 9.0 Administrator Free Practice Exam Questions (2025 Updated)

To deploy theVCF Operations for Logs OVA appliance:

ThevSphere Clientis used to deploy.ovaand.ovftemplates directly into a vCenter environment.

After deployment, the appliance can be configured and integrated with VCF.

Other options:

A. VCF Fleet Management→ Used for multi-instance management, not OVA deployment.

C. VCF Automation→ Provides automation workflows, not appliance deployment.

D. VCF Operations→ Monitoring and analytics platform, not used for OVA installs.

Theprimary purpose of vSphere Lifecycle Manager (vLCM)is to:

Update, patch, and upgrade ESXi hosts, firmware, and drivers.

Manage host consistency across clusters withimage-based lifecycle management.

Other options are unrelated:

A. Configure network settings→ Done through vCenter or host client, not vLCM.

B. Monitor performance→ Done in vCenter/VCF Operations, not vLCM.

C. Create/manage VMs→ Managed through vCenter, not vLCM.

The scenario describes anautomated, repeatable workflow:

Create an AD computer object.

Deploy a VM from a template.

Power on the VM and join domain.

The correct tool isVCF Operations Orchestrator(formerly vRealize Orchestrator), which:

Provides automation and integration withActive DirectoryandvCenter APIs.

Can execute workflows for VM provisioning and domain joining.

Other options:

A. vSphere Supervisor→ Kubernetes workload management, not AD/VM automation.

B. VCF Operations→ Monitoring and analytics, not workflow automation.

C. VCF CLI→ Useful for manual scripting but not suited for automated workflows.

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.

The security team requiresvisibility into vCenter configurationsbut must not make changes.

Best practice is tocreate an Active Directory or vCenter group, add the security users, and assign them theRead-Only roleat thedatacenter/cluster/networklevel.

This ensures each user logs in with unique credentials, maintaining accountability.

Why others are incorrect:

A. Share administrator@vsphere.local password→ Violates security best practices.

B. Create a single user and share credentials→ Still insecure, lacks unique audit trails.

C. Assign Network Administrator role→ Grants configuration permissions, not allowed.

The capability inVMware Cloud Foundation (VCF) Operationsthat directly enablesmonitoring and optimizationof aVMware vSphere Foundation (VVF) environmentisCapacity Analytics.

Capacity Analyticsprovides real-time and predictive insights intoresource utilization, capacity forecasting, and optimization.

It analyzeshistorical and real-time utilization datato predict future workload demands, enabling administrators to proactively plan expansions or right-size workloads.

This includeswhat-if scenario modeling,workload optimization, andresource reclamationto ensure workloads are efficiently placed, avoiding bottlenecks and waste.

Why not the other options?

A. Intelligent Alerts→ Provides proactive alerts and recommendations but is more focused onissue detection and notification, not optimization.

C. Log Insight Integration→ Enables log analysis and troubleshooting, not capacity optimization.

D. Infrastructure Visibility→ Provides monitoring and observability but does not performpredictive optimization.

The requirements:

QA must not lose performance during contention→ QA must haveguaranteed resources, soFixedis correct.

Marketing can use leftover resources when QA is idle→ Marketing must beScalable, so it can borrow resources from QA’s allocation when available.

Other options:

A. Both Fixed→ Marketing would not be able to use QA’s unused resources.

C. QA Scalable, MKT Fixed→ QA would lose guaranteed resources, violating requirements.

D. Not possible→ Incorrect; VMware supports this configuration.

When usingvSphere Lifecycle Manager (vLCM)withParallel Remediationenabled, the following rules apply:

Parallel remediation only applies to ESXi hosts that are already in Maintenance Mode.

vLCM doesnotput hosts into Maintenance Mode automatically in this mode.

Similarly, it does not exit Maintenance Mode automatically after remediation.

Hosts not in Maintenance Mode are skipped.

If Parallel Remediation is activated, vLCM remediates only those hosts that are already in Maintenance Mode.

Any hosts that are not in Maintenance Mode remain untouched.

Remediation happens in parallel for all eligible hosts.

In this case, two of the six hosts are in Maintenance Mode. Those two hosts will be remediated in parallel.

The remaining four hosts (not in Maintenance Mode) willnotbe remediated at all.

Why the other options are incorrect:

A. Four hosts not in maintenance mode are remediated in parallel→❌Incorrect. Hosts must already be in Maintenance Mode to be remediated.

B. Hosts in maintenance mode first, then non-maintenance hosts→❌Incorrect. Non-maintenance mode hosts are skipped, not remediated after.

C. Four hosts remediated sequentially, others skipped→❌Incorrect. Parallel Remediation does not touch non-maintenance mode hosts.

D. Hosts in maintenance mode remediated in parallel; others skipped→✅Correct and matches VMware documentation.

The requirement is for acentralized platformto monitorperformance, health, and capacityacross theentire VMware vSphere Foundation (VVF) environment.

VCF Operations

Providesend-to-end performance monitoring, capacity management, and health analyticsacross vCenter, ESXi, vSAN, and NSX.

IncludesFinOps and Capacity Planning,performance diagnostics, andAI-driven troubleshootingfor faster remediation.

This is the primary component for monitoring theentire VCF environment.

VCF Operations for Networks

Extends observability tonetwork operationsby monitoring NSX health, VPCs, and network flows.

Providestraffic summaries, alerts, and network capacity metrics.

Integrated with VCF Operations to ensure acomplete platform-wide viewof health and performance.

Why not the others?

VCF Operations for Logs→ Focused onlog management, troubleshooting, and diagnostics(not holistic performance/capacity monitoring).

vSphere Supervisor→ ProvidesKubernetes namespace and workload management, not centralized performance/capacity monitoring.

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.

When enabling aSupervisor Cluster in vSphere with Tanzuusing vSphere networking and the Foundation Load Balancer:

You must provide astatic IP rangefor the Supervisor control plane VMs so they can be deployed with dedicated addresses. (B)

You must assign avSphere Distributed Switch (VDS)with an appropriateport groupfor Supervisor networking. (E)

Other options:

A. Namespace template→ Optional after Supervisor is enabled, not required at setup.

C. Tier-0 Gateway→ Applies to NSX networking, not vSphere networking.

D. VM Service→ Enabled after Supervisor, not a prerequisite.

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.

VMware Toolsis a suite of services and drivers installed in a VM. It provides:

Guest OS heartbeat service (B):Used by vCenter to monitor VM health.

Device drivers (C):Optimized drivers for network, storage, graphics, and mouse/keyboard integration.

Other options:

A. Journaling of file system metadata→ Provided by the guest OS filesystem, not VMware Tools.

D. Stores VM configuration files→ Handled by vCenter/ESXi, not VMware Tools.

E. Manages VM hardware configuration→ Done via vSphere Client, not VMware Tools.

When deploying VMware vSphere Foundation using theVCF Installer wizard, host onboarding requires consistent access credentials.

If ESX hosts havedifferent root passwords, the wizard cannot proceed using a single credential.

In this case, administrators must use aJSON specification fileto defineper-host credentials, ensuring each host can be onboarded successfully.

The JSON specification allows defining host-specific parameters (IP, hostname, root password, networking, etc.).

Other options are incorrect:

A. Proceed with wizard and override host credentials during staging→ Not supported.

B. Use deployment wizard and enter credentials per host manually→ Wizard requires uniform credentials.

C. Set password to expire on all ESX hosts→ Irrelevant to deployment and would cause failures.

ThevSphere Foundation 9.0 licensing modelusesper-core licensing.

Current license covers1024 cores.

Existing hosts =960 cores, leaving64 cores licensed.

Adding a96-core host→ 32 cores exceed the license.

Result:

The new host runs inevaluation mode.

If not licensed after the evaluation period, the host isdisconnected from vCenter.

Other options:

A. Limited to 64 cores→ Not how VMware licensing enforcement works.

B. Limited to 64 cores until license upgrade→ Incorrect; VMware does not partially disable cores.

D. No issue→ Incorrect; licensing compliance will cause issues.

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).

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.
