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

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.

For an8-node vSAN OSA cluster, the administrator needs a storage policy that:

Tolerates2 host failures, and

Providesmaximum usable capacity.

RAID-5/6 (erasure coding)is more capacity-efficient than RAID-1 mirroring.

To tolerate2 failures, the correct policy isRAID-5 with FTT=2.

RAID-1 (mirroring) would consume far more capacity, reducing usable space.

Other options:

A. 1 failure - RAID-1→ Only tolerates one failure.

C. 3 failures - RAID-1→ Provides higher resilience but uses much more capacity, not maximum efficiency.

D. 1 failure - RAID-5→ Tolerates only one failure.

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.

Aport groupon avSphere Distributed Switch (VDS)provides:

Logical grouping of virtual ports.

Definesnetwork policiessuch as VLAN IDs, traffic shaping, security policies, and teaming.

Used for segmenting traffic types (vMotion, vSAN, management, VM traffic).

Other options:

A. Enable vSAN connectivity→ Achieved by assigning vSAN traffic to a port group, but not the main definition.

B. Allocate CPU/memory resources→ Done via resource pools, not port groups.

D. Manage storage I/O performance→ Done with Storage I/O Control, not port groups.

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.

In avSAN Original Storage Architecture (OSA)cluster, the choice of storage policy directly impacts storage efficiency and resilience:

Current Setup:

Eight-node cluster, 1 disk group per node.

VMs are usingFTT=1 RAID-1 (mirroring)policy.

Storage utilization is already at70%.

RAID-1 (Mirroring):

Each piece of data is mirrored, requiring2x storage capacity.

Space efficiency ~50%.

RAID-6 (Erasure Coding, FTT=2):

Requires a minimum of6 hosts, satisfied here with 8.

Uses erasure coding instead of full mirroring, giving ~67% space efficiency.

Provides resilience against2 host failureswhile using less space than RAID-1.

Thus, switching fromRAID-1 FTT=1toRAID-6 FTT=2reduces overall storage utilization while still improving resilience.

Why not the other options?

A. Enable Deduplication and Compression→❌In OSA, enabling this requires acluster-wide disk group reformat, which is disruptive and not the minimal impact choice.

B. Change policy to 3 failure - RAID-1→❌Increases redundancy but consumesmuch more capacity, worsening utilization.

C. Enable Compression only→❌Not available in OSA (only in ESA). OSA supportsdeduplication + compression together, not compression-only.

D. Change to 2 failure - RAID-6→✅Meets resilience requirements,reduces storage usage, and is supported on 8-node OSA clusters.

InVCF Operations for Logs, administrators can analyze logs using queries, fields, and charts. A key feature is the ability toview the value range of a specific field.

When a log query is executed, results appear in theEvents table.

Each field shown in the Events table is interactive.

Byclicking on a field in the Events table, administrators can drill down into the data tovisualize its value distribution (range), typically in the form of a histogram or grouped data set.

This provides insight intowhat values are present and how frequently they occur, which is useful for troubleshooting, anomaly detection, and refining queries.

Why not the other options?

A. Click the pencil in the Manage Fields pane→ Used toedit or extract fields, not visualize ranges.

C. Click on the field in Manage Fields→ Displays field definitions and settings, not real-time value ranges.

D. Click on the field in the Field Table→ The Field Table lists defined fields but does not provide value range visualization.

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.

ForvSAN ESA (Express Storage Architecture), minimum requirements differ from OSA:

25GbE NICsare required to handle high-performance traffic. (C)

NVMe PCIe flash devicesmust be used for storage. (D)

128GB Memory minimumper host is required. (F)

Other options:

A. 10GbE→ Only supported in vSAN OSA, not ESA.

B. 256GB Memory→ Recommended for large workloads, not minimum.

E. SAS SSDs→ Not supported in ESA; NVMe required.

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.

To satisfy both IT and executive requirements:

IT team→ Needsdetailed technical metrics, which are available throughOut-of-the-Box dashboards in VCF Operations. (A)

Executives→ Need acustom KPI-focused dashboard, with summaries and high-level visibility. This can be shared via aURL linkthat always shows the latest data. (B)

Why others are incorrect:

C. Custom dashboard in VCF Operations for Logs→ Logs are not KPI-focused performance metrics.

D. Out-of-the-Box dashboards in VCF Automation→ VCF Automation is not designed for KPI reporting.

To allowActive Directory domain users(corp.local) to authenticate in vCenter with domain credentials:

The correct method is configuringActive Directory over LDAP as an identity source. (D)

This uses thedefault AD protocol (LDAP/Kerberos)without requiring SAML or OIDC federation.

Other options:

A. Adding domain controller certificate→ Needed for LDAPS but not the main step.

B. Identity Federation with SAML→ Requires federation, not allowed per requirements.

C. OpenID Connect (OIDC)→ Used for external IdPs, not traditional AD auth.

VCF Operations requires that custom SSL certificates meet these requirements:

Certificates and private key must be inPEM format. (A)

Theserver certificate must be listed firstin the file. (D)

The file must include theserver certificate, private key, and full certificate chain(issuing/intermediate/root CA). (E)

Why others are wrong:

B. Server certificate last→ Incorrect, it must be first.

C. Cannot use SAN extension→ Incorrect, SAN is supported and recommended.

F. PFX format→ Not supported for VCF Operations.

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 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.
