VCP-DCV Practice Test 15 — 15 Questions

Question 1

A vSphere environment uses Active Directory for authentication. The administrator notices that users from a specific AD group cannot log in to the vCenter Server, although other AD users can. The group is added to vCenter Server with the correct permissions. What is the most likely cause?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The domain of the group is not configured as an identity source in vCenter Single Sign-On. The most likely cause is that the domain of the group is not configured as an identity source in vCenter Single Sign-On. Even if the group is added with correct permissions in vCenter Server, vCenter SSO must be able to authenticate users against the domain. Without the domain listed as an identity source, vCenter cannot validate the credentials of users from that group, causing authentication failures for all users in that domain.

Answer

The users are not members of the vCenter Single Sign-On domain

Answer

The user accounts have expired passwords

Answer

The group is nested within another group

Question 2

A vSphere administrator is planning a Storage DRS implementation for a datastore cluster containing multiple VMFS datastores. The VMs have various I/O patterns. Some VMs should always remain together on the same datastore. Which configuration should be used?

Accepted Answer

Create a VM-to-VM affinity rule in the datastore cluster.. Storage DRS supports VM-to-VM affinity rules within a datastore cluster, which ensure that specified VMs are always placed on the same datastore. This is the correct configuration when VMs must remain together, such as for application clusters that require shared storage locality or licensing constraints. The rule is enforced during initial placement and during Storage DRS migrations.

Answer

Set individual datastore affinity rules on each host.

Answer

Apply Storage I/O Control with high shares to the VMs.

Answer

Create a VM-to-VM anti-affinity rule in the datastore cluster.

Question 3

A vSphere administrator is planning to upgrade a vSphere 7.0 U3 cluster to vSphere 8.0. The cluster currently uses vSphere Lifecycle Manager (vLCM) with a single image. After the upgrade, the administrator wants to ensure that all ESXi hosts apply firmware updates from a hardware support manager (HSM) integrated with vLCM. Which step must the administrator take before starting the cluster upgrade?

Accepted Answer

Ensure the desired ESXi version and firmware component are specified in the vLCM image.. VLCM with a single image can include both the ESXi version and firmware components from an integrated hardware support manager (HSM). By specifying the desired ESXi version and firmware component in the vLCM image, the administrator ensures that during the cluster upgrade, vLCM will apply the firmware updates provided by the HSM as part of the image-based remediation process. This is the required step before starting the upgrade to vSphere 8.0.

Answer

Disable vLCM and use baseline-based remediation for the upgrade.

Answer

Create separate baselines for ESXi and firmware and attach them to the cluster.

Answer

Remove the HSM integration because vLCM cannot apply firmware updates.

Question 4

A company plans to deploy a new homogeneous cluster with vSphere 8. They want to use vLCM to simplify lifecycle management. What is the recommended approach for maintaining the ESXi hosts?

Accepted Answer

Define a single cluster image and apply it to all hosts.. vLCM (vSphere Lifecycle Manager) uses a desired-state model where a single cluster image defines the ESXi base image, vendor add-on, and firmware. Applying one image to all hosts in a homogeneous cluster ensures consistency and simplifies patching and upgrades.

Answer

Manually upgrade each host via ISO and then import into vLCM.

Answer

Use vSphere baselines to manage patches.

Answer

Create separate images for each host based on its hardware.

Question 5

An administrator is analyzing performance data for a vSphere cluster and wants to identify VMs that are experiencing memory pressure. Which two metrics from esxtop or vCenter performance charts reliably indicate that a VM is actively reclaiming memory due to contention? (Choose two.)

Accepted Answer

Ballooned memory. Ballooned memory (C) is correct because the balloon driver inflates inside the guest only when the ESXi host is under memory pressure and needs to reclaim pages from the VM, so a non-zero balloon value directly signals active reclamation due to contention. Swapped memory (D) is correct because host-level swapping occurs when the hypervisor has exhausted other reclamation options and forcibly moves VM pages to the swap file, which reliably indicates severe memory contention. Consumed memory (A) merely reflects the amount of physical host memory currently mapped to the VM and can be high without any pressure. Active memory (B) measures the recently touched working set and is used for sizing, not for detecting reclamation. Overhead memory (E) is the fixed cost of virtualization resources for the VM and has no bearing on contention.

Answer

Consumed memory

Answer

Active memory

Answer

Overhead memory

Question 6

An administrator needs to migrate a powered-on VM from one datastore to another without any downtime. Which vSphere feature should be used?

Accepted Answer

Storage vMotion. Storage vMotion migrates a powered-on VM's virtual disks from one datastore to another with zero downtime, keeping the VM running throughout the copy. It is the correct feature when the requirement is datastore-level migration of a live VM.

Answer

Storage DRS

Answer

vSphere Replication

Answer

vSphere vMotion

Question 7

A vSphere administrator needs to apply a critical ESXi security patch to a cluster of 10 hosts. The cluster is managed by vLCM using image-based management. What is the correct procedure to apply the patch?

Accepted Answer

Update the cluster image to include the patched version and remediate the cluster.. In vLCM image-based management, patches are applied by updating the cluster's image to a newer ESXi base image version that includes the patch, then remediating the cluster. vLCM computes the difference between the current host state and the desired image state and applies only the necessary changes, rolling through hosts per the remediation settings (e.g., maintenance mode, DRS). This is the correct image-based workflow.

Answer

Create a new baseline group with the patch and attach it to the cluster.

Answer

Manually update each host using the patch's ISO.

Answer

Use vCenter Update Manager to push the patch as a baseline.

Question 8

After adding a new ESXi host to a vLCM-managed cluster, the compliance status shows 'Non-Compliant'. All other hosts in the cluster are compliant. The cluster uses a custom image. Which is the most likely cause of the non-compliance?

Accepted Answer

The host's software inventory differs from the cluster image.. In vSphere Lifecycle Manager (vLCM), a cluster image defines the exact desired software specification (ESXi base image, firmware add-ons, and components) for all hosts. When a new host is added, vLCM compares its actual software inventory against the cluster image. If any installed VIB, driver, or component version differs from the image, the host is marked Non-Compliant. Since all other hosts are compliant, the cluster image itself is valid and properly applied; the new host simply hasn't been remediated to match the image yet. Therefore, the most likely cause is that the host's software inventory differs from the cluster image.

Answer

The cluster image has not been exported to the host.

Answer

The host profile is not attached to the host.

Answer

The cluster image is corrupted.

Question 9

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.. The correct approach is to place each host in maintenance mode, evacuate vSAN data, upgrade, and rejoin the cluster. This ensures vSAN data availability and cluster quorum are maintained throughout the upgrade, minimizing downtime. vSAN requires that data be migrated off a host before it enters maintenance mode with 'Ensure Accessibility' or 'Full Data Migration' to preserve policy compliance.

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 10

Order the steps to enable vSphere HA on a cluster.

Accepted Answer

Step 1: Select the cluster, Step 2: Access HA settings, Step 3: Enable vSphere HA, Step 4: Configure HA options, Step 5: Confirm changes. The correct sequence for enabling vSphere HA ensures that all prerequisites are met, starting with cluster selection, then accessing the HA configuration page, toggling the enable option, customizing settings, and applying changes. Common mistakes include attempting to configure options before enabling HA or accessing settings before selecting the cluster.

Answer

Step 1: Select the cluster, Step 2: Enable vSphere HA, Step 3: Access HA settings, Step 4: Configure HA options, Step 5: Confirm changes

Answer

Step 1: Access HA settings, Step 2: Select the cluster, Step 3: Enable vSphere HA, Step 4: Configure HA options, Step 5: Confirm changes

Answer

Step 1: Select the cluster, Step 2: Configure HA options, Step 3: Access HA settings, Step 4: Enable vSphere HA, Step 5: Confirm changes

Question 11

Arrange the steps to convert a virtual machine to a template.

Accepted Answer

Power off the virtual machine, right-click and select Convert to Template, confirm the conversion, wait for the task to complete, verify the template appears in the inventory.. To convert a VM to a template in vSphere, you must first power off the VM, then right-click it and select Convert to Template, confirm the operation, wait for the task to finish, and finally verify the template in the inventory. This ensures the VM is not in use and the conversion process is properly executed.

Answer

Right-click and select Convert to Template, confirm the conversion, power off the virtual machine, wait for the task to complete, verify the template appears in the inventory.

Answer

Power off the virtual machine, confirm the conversion, right-click and select Convert to Template, wait for the task to complete, verify the template appears in the inventory.

Answer

Power off the virtual machine, wait for the task to complete, right-click and select Convert to Template, confirm the conversion, verify the template appears in the inventory.

Question 12

Which THREE are valid methods to isolate and secure management traffic on a vSphere Distributed Switch? (Choose three.)

Accepted Answer

Assign a specific VLAN ID to the management port group.. Assigning a specific VLAN ID to the management port group isolates management traffic at Layer 2 by tagging frames with a unique VLAN identifier. This prevents unauthorized access from other VLANs and ensures that management traffic is logically separated from other network traffic on the same vSphere Distributed Switch.

Answer

Enable Route based on IP hash on the management port group.

Answer

Use Private VLANs on the management port group.

Question 13

A vSphere cluster has DRS enabled and hosts with unbalanced resource usage. Which DRS feature automatically migrates VMs to balance CPU and memory loads across hosts?

Accepted Answer

Distributed Resource Scheduler (DRS). DRS (Distributed Resource Scheduler) uses vMotion to migrate VMs based on resource utilization thresholds, balancing workloads across hosts. HA provides failover, EVC ensures compatibility, and SIOC manages storage I/O.

Answer

High Availability (HA)

Answer

Enhanced vMotion Compatibility (EVC)

Answer

Storage I/O Control (SIOC)

Question 14

Refer to the exhibit. What is the cause of the non-compliance?

Accepted Answer

The host is running an older ESXi version than desired. In vSphere Lifecycle Manager (vLCM) image-based compliance, a host is marked non-compliant when its installed ESXi version does not match the version specified in the desired image. The exhibit shows a version mismatch between the host's current ESXi build and the target image, which is the direct cause of non-compliance. Firmware, scan failures, and hardware support are separate checks that would produce different error indicators.

Answer

The host has an outdated firmware version

Answer

The compliance scan failed

Answer

The host's hardware is not supported

Question 15

An administrator needs to separate vMotion traffic from management traffic. Which should be created?

Accepted Answer

A new VMkernel adapter on a different subnet.. Separating vMotion traffic from management traffic requires a dedicated VMkernel adapter, because VMkernel adapters carry vMotion, management, and other system traffic. Placing it on a different subnet ensures traffic isolation at Layer 3 and prevents vMotion from competing with management on the same network.

Answer

A new physical NIC.

Answer

A new VLAN on the existing port group.

Answer

A new standard switch port group.
