VCP-DCV Practice Test 9 — 10 Questions

Question 1

An administrator needs to migrate a running VM from one datastore to another without any downtime. Which vSphere feature allows this?

Accepted Answer

Storage vMotion. Storage vMotion is the vSphere feature specifically designed to migrate a running VM's virtual disks (files) from one datastore to another while the VM remains powered on and continues serving workloads. It leverages a mirroring mechanism that copies disk blocks to the destination datastore and performs a fast switchover, achieving zero downtime. This is distinct from compute vMotion, which moves the VM's execution state between ESXi hosts.

Answer

Cross vCenter vMotion

Answer

Storage DRS

Answer

vMotion

Question 2

An administrator wants to replicate a critical VM to a remote site with a Recovery Point Objective (RPO) of 15 minutes. Which vSphere feature should be used?

Accepted Answer

vSphere Replication. vSphere Replication is the correct feature because it provides asynchronous replication of VMs to a remote site with an RPO as low as 15 minutes. It operates at the VM level and is included with vSphere, making it suitable for this requirement without additional licensing for SRM.

Answer

Storage vMotion

Answer

vSphere vMotion

Answer

Site Recovery Manager (SRM)

Question 3

Which TWO of the following are characteristics of vSphere High Availability (HA) heartbeat networks? (Choose two.)

Accepted Answer

Datastore heartbeats can be used as a secondary heartbeat mechanism.. Option A is correct because vSphere HA uses datastore heartbeats as a secondary mechanism to determine whether a host is isolated or has failed when management network heartbeats are unavailable. Option C is correct because the management network is the primary heartbeat network used by HA agents to exchange heartbeats between hosts in the cluster. Option B is incorrect because HA heartbeats do not require a separate physical network; they use the management network by default. Option D is incorrect because the default isolation address is the default gateway of the host's management network, not the vCenter Server IP address. Option E is incorrect because HA heartbeats are sent over the management network, not the VM network.

Answer

A separate physical network is required for HA heartbeats.

Answer

The default isolation address is the vCenter Server IP address.

Answer

Heartbeats are sent over the VM network to avoid interference with management traffic.

Question 4

An administrator manages a cluster of 10 identical ESXi hosts using vLCM with image-based management. After importing a new hardware support package (HSP) and applying a new image specification, 5 hosts report non-compliant with the error 'Firmware version not supported'. The compliant hosts and non-compliant hosts are from the same vendor model. What is the most likely cause?

Accepted Answer

The firmware version on the non-compliant hosts is newer than what the hardware support package supports.. The error 'Firmware version not supported' in vLCM image-based management indicates that the HSP (Hardware Support Package) included in the image specification does not support the firmware version currently running on the non-compliant hosts. HSPs are vendor-provided bundles that define supported firmware/driver combinations for specific hardware models. If the hosts have a newer firmware version than what the HSP was validated against, vLCM flags them as non-compliant because the HSP cannot guarantee compatibility. Since all hosts are the same vendor model, the difference must be in firmware version, not hardware model or image application.

Answer

The image specification was applied only to the compliant hosts.

Answer

The non-compliant hosts have a different manufacturer than the compliant ones.

Answer

The vLCM service failed to download the HSP to the non-compliant hosts.

Question 5

Refer to the exhibit. An administrator attempts to apply this cluster image to an ESXi 8.0.1 cluster, but the image validation fails. What is the most likely cause?

Accepted Answer

The vendor addon 'VXLAN/5.6.0' is not compatible with ESXi 8.0.1.. The vendor addon 'VXLAN/5.6.0' is explicitly listed as incompatible with the ESXi 8.0.1 base image. In vSphere Lifecycle Management, a cluster image consists of an ESXi base image, optional vendor addons, and firmware/driver components. If a vendor addon version is not certified or supported for the selected base image version, image validation will fail. The error indicates that the VXLAN addon version 5.6.0 does not meet compatibility requirements for ESXi 8.0.1.

Answer

The 'nmlx5-core' component version is incompatible with the selected ESXi base image.

Answer

The firmware section is empty.

Answer

The 'Intel-i40en' component is missing a critical bug fix.

Question 6

A vSphere environment experiences periodic performance degradation during peak business hours. Analysis shows that one ESXi host's CPU ready time for a specific mission-critical VM is consistently above 20%. Which corrective action should be taken first?

Accepted Answer

Migrate the VM to a different host with lower CPU utilization. CPU ready time above 20% indicates the VM is waiting for physical CPU resources because the host is overcommitted or contended. The first corrective action should be to migrate the VM to a less-utilized host (vMotion), which immediately relieves contention without changing the VM's configuration. This addresses the root cause — host-level CPU contention — rather than masking it.

Answer

Increase the VM's memory reservation

Answer

Set a higher CPU limit on the VM

Answer

Add more vCPUs to the VM

Question 7

A vSphere cluster has DRS enabled with 'Partially automate' mode. A VM is consistently showing high CPU ready time. The administrator wants to ensure the VM is automatically migrated to a less loaded host. What must be done?

Accepted Answer

Set the VM's DRS automation level to 'Automatic'. In a DRS cluster with 'Partially automate' mode, the cluster-wide automation level is overridden by per-VM settings. To ensure a VM is automatically migrated for load balancing, the VM's DRS automation level must be set to 'Automatic'. This allows DRS to perform migrations without manual intervention for that VM.

Answer

Enable EVC mode on the cluster

Answer

Set the VM's DRS automation level to 'Manual'

Answer

Enable HA admission control

Question 8

A company has a vSphere cluster consisting of 8 ESXi hosts connected to a single Fibre Channel SAN array. They use VMFS6 datastores to store virtual machine files. The storage administrator has scheduled a firmware upgrade for the SAN array that requires a controller reboot. This will cause a temporary loss of connectivity to one LUN (datastore) for approximately 5 minutes. The datastore hosts 15 production VMs, including critical database servers. The cluster has sufficient spare capacity on other datastores, but the VMs are large (each about 200 GB). The vSphere administrator must ensure that these VMs remain available during the upgrade. The cluster has vSphere HA enabled with default settings. What should the administrator do to meet the requirement?

Accepted Answer

Use Storage vMotion to migrate all VMs on the affected datastores to a healthy datastore before the upgrade.. Storage vMotion migrates the VMs' files to a different datastore while they remain powered on, so when the affected LUN goes offline for the controller reboot the VMs are no longer dependent on it and stay available. This directly addresses the requirement of continuous availability during a planned 5-minute storage outage. The other options either don't move the VMs off the impacted datastore or address unrelated concerns (HA admission control, host maintenance, I/O prioritization).

Answer

Configure a vSphere HA admission control policy to reserve resources in case of host failure.

Answer

Place all ESXi hosts into maintenance mode.

Answer

Enable Storage I/O Control on the affected datastore to manage I/O during the upgrade.

Question 9

Arrange the steps to add an existing virtual machine to a vCenter Server inventory.

Accepted Answer

Right-click a datacenter or folder, click 'Add Existing Virtual Machine', browse to and select the VM's .vmx file, then click Finish.. The correct sequence to add an existing VM to vCenter inventory is: right-click a datacenter or folder, select 'Add Existing Virtual Machine', browse to the VM's .vmx file, and click Finish. This order ensures the wizard is properly initiated and the VM is registered in the desired inventory location.

Answer

Browse to and select the VM's .vmx file, right-click a datacenter or folder, click 'Add Existing Virtual Machine', then click Finish.

Answer

Click 'Add Existing Virtual Machine', right-click a datacenter or folder, browse to the VM's .vmx file, then click Finish.

Answer

Right-click a datacenter or folder, click Finish, browse to and select the VM's .vmx file, then click 'Add Existing Virtual Machine'.

Question 10

Match each vSphere component to its primary function.

Accepted Answer

vCenter Server: Centralized management platform for vSphere environments. The correct matches: vCenter Server is the centralized management platform; ESXi is the hypervisor; vSphere vMotion enables live migration; vSphere HA provides high availability. Common confusions include mixing up management functions with migration or HA features.

Answer

vCenter Server: Live migration of VMs without downtime

Answer

ESXi: High availability by restarting VMs on failed hosts
