VCP-DCV Practice Test 3 — 10 Questions

Question 1

A company wants to minimize downtime during an ESXi upgrade from 7.0 to 8.0 on a vSAN cluster. What is the best approach?

Accepted Answer

Place each host in maintenance mode, evacuate vSAN data, upgrade, and rejoin the cluster.. It ensures data availability by evacuating vSAN data before upgrading each host sequentially. Option A would cause downtime; Option B is incorrect because upgrading all hosts at once after vCenter upgrade still causes downtime; Option D (Quick Boot) reduces reboot time but does not address vSAN evacuation.

Answer

Upgrade all hosts simultaneously to complete faster.

Answer

Upgrade vCenter Server first, then upgrade all hosts at once.

Answer

Use Quick Boot feature to speed up the upgrade process.

Question 2

Which TWO troubleshooting steps should an administrator take when a host fails to remediate and shows 'compliance error: host firmware mismatch' in a vLCM cluster? (Choose two.)

Accepted Answer

Check the compliance status in the vSphere Client cluster monitor.. Correct options are C and D. Checking the compliance status in the vSphere Client cluster monitor allows the administrator to see detailed compliance information for the host, including specific mismatches. Reviewing the software FCoE, VLAN, and driver versions in the cluster image is a troubleshooting step to identify component mismatches that could cause firmware errors. Option A is incorrect because removing and re-adding a host does not address the underlying firmware mismatch. Option B is incorrect because manually upgrading all hosts is unnecessary and not a targeted troubleshooting step. Option E is incorrect because disabling the cluster image and using a baseline group would change the management approach but does not resolve the compliance error related to firmware mismatch in a vLCM cluster.

Answer

Remove the host from the cluster and re-add it.

Answer

Manually upgrade all hosts to the latest ESXi version.

Answer

Disable the cluster image and use a baseline group instead.

Question 3

Which TWO conditions are required to use vLCM for firmware management? (Select TWO.)

Accepted Answer

Hardware support manager (HSM) installed for each vendor. To manage firmware via vLCM, two conditions are required: a Hardware Support Manager (HSM) must be installed for each vendor (option A), and vLCM must be enabled for the cluster (option E). While vCenter Server 7.0 or later is a general prerequisite for vLCM, it is not a condition specific to firmware management. Options B and D are incorrect because identical hardware or a fully automated DRS cluster are not requirements for firmware management with vLCM.

Answer

vCenter Server 7.0 or later

Answer

All hosts in the cluster must be identical hardware

Answer

Hosts must be in a fully automated DRS cluster

Question 4

A vSphere administrator is moving from baseline-based to image-based management for a cluster. The administrator has detached all baselines and is now ready to attach an image. Which TWO conditions must be met before attaching an image to the cluster? (Choose two.)

Accepted Answer

The cluster must have at least one host that is compatible with the selected image.. Options C and D are correct. For attaching an image to a cluster, the cluster must have at least one host that is compatible with the selected image (C) to ensure the image can be applied. Additionally, all hosts in the cluster must be in a connected state (D) so that vSphere Lifecycle Manager can manage them. Option A is incorrect because the vCenter Server does not need to be running the latest version of vLCM; image-based management is supported in vSphere 7.0 and later, but not specifically 'the latest'. Option B is incorrect because the cluster can contain virtual machines; image-based management does not require an empty cluster. Option E is incorrect because pending remediation tasks do not block attaching an image; they may be addressed later.

Answer

The vCenter Server must be running the latest version of vSphere Lifecycle Manager.

Answer

The cluster must be empty of any virtual machines.

Answer

The cluster must not have any pending remediation tasks.

Question 5

Which THREE factors should be considered when planning a rolling upgrade of ESXi hosts in a vSphere cluster from version 7.0 to 8.0 using vLCM?

Accepted Answer

Check the compatibility of third-party VIBs with ESXi 8.0.. For a rolling upgrade of ESXi hosts from 7.0 to 8.0 using vLCM, you must check the compatibility of third-party VIBs with ESXi 8.0 (A). Additionally, the vCenter Server must be upgraded to 8.0 before upgrading ESXi hosts because vCenter manages the cluster (B). The VUM rollback feature, which is available in vLCM, should be configured to allow revert in case of failure (D). Option C is incorrect because hardware compatibility must be verified via the VMware Compatibility Guide (HCL), not assumed just because it is a major release. Option E is incorrect because vSphere DRS should be enabled to allow automated VM migration during host maintenance, not disabled.

Answer

Assume that all server hardware is supported by ESXi 8.0 since it is a major release.

Answer

Disable vSphere DRS to prevent VM migration during host maintenance.

Question 6

A company manages a vSphere 8 cluster with vLCM enabled. The administrator needs to remediate the cluster to apply a security patch. What should the administrator do to minimize performance impact on running workloads?

Accepted Answer

Enable Quick Boot in the cluster image configuration.. Quick Boot significantly reduces host reboot time during remediation, minimizing the time hosts spend in maintenance mode and thus reducing performance impact on running workloads. Options B, C, and D are incorrect: vSphere Live Migration (B) is for vMotion, not patching; legacy baselines (C) are deprecated with vLCM; disabling DPM (D) does not directly address remediation performance impact.

Answer

Use vSphere Live Migration to move workloads before remediation.

Answer

Use legacy baselines instead of vLCM to allow rolling updates.

Answer

Disable Distributed Power Management (DPM) to prevent hosts from powering off during remediation.

Question 7

During a cluster upgrade using vLCM, the pre-check reports that Quick Boot is disabled. How does this affect the upgrade?

Accepted Answer

Hosts will reboot normally. Quick Boot is an optional optimization that reduces reboot time by temporarily booting from a snapshot. When Quick Boot is disabled, hosts will reboot normally during remediation, and the upgrade proceeds without failure. Option A is incorrect because Quick Boot speeds up reboot, but its disablement does not cause upgrade failure; hosts just reboot normally. Option B is incorrect because disabling Quick Boot does have an effect: hosts will reboot normally instead of using the faster Quick Boot method. Option D is incorrect because the upgrade will not fail due to Quick Boot being disabled.

Answer

Quick Boot speeds up reboot

Answer

No effect

Answer

Upgrade will fail

Question 8

Refer to the exhibit. What does this output indicate?

Accepted Answer

The host has been upgraded to ESXi 8.0.0, but the previous profile remains. The `esxcli software profile list` output shows multiple software profiles on the host. After upgrading from ESXi 7.0U3 to 8.0.0, the old profile remains stored in the bootbank but is not active. The active profile is the one most recently installed (ESXi-8.0.0-789012). This is normal behavior and indicates that the host has been upgraded to ESXi 8.0.0, but the previous profile is still present. Therefore, option A correctly describes this situation.

Answer

The host has two ESXi installations and can boot into either

Answer

The host's profile is corrupted

Answer

The host is running both versions simultaneously

Question 9

Which THREE of the following are prerequisites for configuring LACP on a vSphere Distributed Switch? (Select exactly three.)

Accepted Answer

The vSphere Distributed Switch must be configured with enhanced LACP support.. Options A, C, and E are correct. For LACP on a vSphere Distributed Switch, the vDS must be configured with enhanced LACP support (option A). The physical switch ports must be configured for LACP, either in active or passive mode (option C). Additionally, the physical network switch must support LACP (IEEE 802.3ad) (option E). Option B is incorrect because each uplink does not need to be in a separate VLAN; LACP works across VLANs and VLAN configuration is independent. Option D is incorrect because the uplinks must be connected to the same physical switch to form a LAG; using different switches requires Multi-chassis LACP (e.g., MLAG).

Answer

Each uplink must be in a separate VLAN to avoid loops.

Answer

The uplinks must be connected to different physical switches for redundancy.

Question 10

Which two conditions must be met for a VMkernel adapter to be used for vMotion on a distributed switch? (Choose two.)

Accepted Answer

The VMkernel adapter must be in the same subnet as the destination host.. Options A and B are correct. The VMkernel adapter must be in the same subnet as the destination host (A) to allow vMotion traffic to route properly, and it must be enabled for vMotion (B) in the adapter properties. Other options are not required: active/standby mode (C) is not a requirement; VLAN ID can be any valid VLAN (D); and static IP is not necessary (E) as DHCP can be used.

Answer

The physical uplinks must be in active/standby mode.

Answer

The port group must have VLAN ID 0.

Answer

The port group must be configured with a static IP address.
