Pass the VMware VCP-VVF Admin 2V0-16.25 Questions and answers with ExamsMirror

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.

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.

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 requirement is to followleast privilegewhile granting specific VM operations:

Power on/off virtual machines

Open consoles

Create snapshots

TheVirtual Machine Power Userrole is the correct out-of-the-box role, as it includes all these privileges without granting unnecessary administrative access.

Other roles:

Administrator (A):Grants full environment control → too broad.

Virtual Machine Console User (B):Limited to console access, cannot power on/off or snapshot.

Virtual Machine User (C):Can interact with VMs but lacks snapshot privileges.

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.

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.

In avSAN Original Storage Architecture (OSA) cluster, the feature that provides themaximum storage space reductionisDeduplication and Compression.

Deduplication removes duplicate blocks across the cluster.

Compression further reduces the space used by unique blocks.

These are applied at thedisk group leveland are essential inVDI environmentswhere identical VM images consume space.

Why others are incorrect:

A. Disable Object Checksum→ Only reduces CPU overhead, not storage space.

C. Object space reservation→ Controls reserved capacity, not reduction.

D. Compression only→ Reduces space, but less than Deduplication + Compression combined.

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.

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.

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.
