VCP-DCV Practice Test 6 — 10 Questions

Question 1

An administrator is troubleshooting a virtual machine that experiences intermittent performance issues. The VM is configured with 8 vCPUs and 32 GB memory. The administrator runs esxtop and sees that the %RDY for the VM is consistently above 20%. What does this indicate?

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

Accepted Answer

The VM is contending for CPU resources due to overallocation of vCPUs.. High %RDY indicates that the VM is ready to run but is waiting for CPU resources, meaning the CPU scheduler cannot allocate physical cores quickly enough. This is typically caused by over-allocation of vCPUs relative to available physical cores, leading to contention. Option A correctly identifies this condition. Option B is incorrect because high %RDY is not related to disk latency; disk latency is measured by other metrics like DAVG/GAVG. Option C is incorrect because memory ballooning is a memory management technique, not directly indicated by %RDY. Option D is incorrect because high %RDY signifies inefficient CPU scheduling, not efficient utilization.

Answer

The VM's virtual disks are experiencing high latency.

Answer

The VM is experiencing memory ballooning.

Answer

The VM is using its CPU resources efficiently.

Question 2

A vSphere administrator is troubleshooting a failed remediation attempt on an ESXi host in a cluster managed by vLCM. The image compliance status shows 'Non-Compliant'. The host is in maintenance mode. The administrator sees the following error: 'Failed to apply the software specification. Reason: The host's firmware version is incompatible with the selected ESXi image.' What is the most likely cause?

Accepted Answer

The hardware support manager (HSM) is not configured or the firmware baseline is outdated.. The error indicates that the host's firmware version is incompatible with the selected ESXi image. In vLCM, hardware compatibility is managed by the Hardware Support Manager (HSM), which provides firmware baselines. If the HSM is not configured or the firmware baseline is outdated, vLCM cannot validate or update the firmware to match the ESXi image requirements, leading to a 'Non-Compliant' status and remediation failure. This is the most likely cause because the error directly points to firmware incompatibility, not driver issues or image corruption.

Answer

The host must be taken out of maintenance mode for the remediation to proceed.

Answer

The ESXi 8.0 image has deprecated certain drivers that are still in use.

Answer

The vLCM image is corrupted and needs to be re-imported.

Question 3

Order the steps to perform a vMotion migration of a powered-on virtual machine.

Accepted Answer

Verify prerequisites, Initiate migration, Select migration type, Choose destination, Confirm settings. Prerequisites check, initiate migration, select type, choose destination, and confirm.

Answer

Select migration type, Verify prerequisites, Initiate migration, Choose destination, Confirm settings

Answer

Initiate migration, Choose destination, Select migration type, Verify prerequisites, Confirm settings

Answer

Confirm settings, Initiate migration, Verify prerequisites, Choose destination, Select migration type

Question 4

Arrange the steps to create a new virtual machine in vSphere Client.

Accepted Answer

Initiate creation, then enter name and folder, then select compute resource, then select datastore, then configure hardware settings.. The standard workflow: initiate creation, choose type, name/place, select compute, then storage and settings.

Answer

Initiate creation, then enter name and folder, then select datastore, then select compute resource, then configure hardware settings.

Answer

Initiate creation, then select compute resource, then enter name and folder, then select datastore, then configure hardware settings.

Answer

Initiate creation, then select datastore, then enter name and folder, then select compute resource, then configure hardware settings.

Question 5

Refer to the exhibit. An administrator tries to enable vSAN on a host and receives this error. What is the most likely cause?

Accepted Answer

The host has disks but they are not claimed for vSAN or not configured in a disk group.. vSAN requires at least one disk group consisting of one or more capacity disks (and optionally a cache disk). The error indicates that no disk group is present or the disks are not properly claimed.

Answer

The vSAN cluster has insufficient hosts (needs at least 2).

Answer

The host does not have any disks installed.

Answer

The host's disks are all SSD and vSAN requires HDD for capacity tier.

Question 6

Refer to the exhibit. An administrator notices that two uplinks are down on the VDS. Which step should be taken first to restore redundancy?

Accepted Answer

Check the physical switch ports and cables for uplink2 and uplink3.

Answer

Increase the MTU to 9000 to improve performance.

Answer

Disable LACP on the VDS to allow single-uplink operation.

Answer

Remove the down uplinks from the VDS.

Question 7

An ESXi host is connected to an iSCSI storage array using software iSCSI initiator. The administrator has configured two NICs for iSCSI traffic. During setup, the administrator selects 'Round Robin' as the path policy for the storage device. What is the benefit of this path policy?

Accepted Answer

It load balances I/O across all active paths. Round Robin is a VMware PSA (Pluggable Storage Architecture) path selection policy that actively distributes I/O across all active paths to a given device in a rotating fashion. With two iSCSI NICs configured, Round Robin sends commands down both paths, increasing aggregate throughput and utilizing both NICs simultaneously. This is the defining benefit of Round Robin compared to failover-only policies.

Answer

It uses a single path until failure, then switches to another

Answer

It minimizes latency by always using the path with lowest latency

Answer

It provides the highest performance for all workloads

Question 8

An administrator needs to capture traffic from a specific virtual machine for troubleshooting. Which vSphere networking feature should be used?

Accepted Answer

Port mirroring on the VDS.. Port mirroring on a vSphere Distributed Switch (VDS) copies traffic from a source VM's vNIC (or uplink) to a destination port where a packet analyzer is attached. It is the purpose-built feature for capturing VM traffic for troubleshooting, supporting both ingress/egress directions and multiple session types.

Answer

LLDP on the VDS.

Answer

NetFlow on the VDS.

Answer

Traffic shaping on the VDS.

Question 9

A vSphere administrator manages a cluster of 50 ESXi hosts using vLCM with image-based management. The cluster includes hosts from two different hardware vendors. The administrator needs to ensure firmware updates are consistently applied across all hosts. What is the best practice for this scenario?

Accepted Answer

Create separate cluster images for each hardware vendor and apply to respective hosts.. In vLCM image-based management, a cluster image is a single desired-state specification that includes ESXi base image, vendor add-ons, and firmware add-ons. Firmware add-ons are hardware-vendor-specific (e.g., Dell, HPE, Lenovo), so a single image cannot contain firmware components for two different vendors. The correct best practice is to create separate cluster images per hardware vendor, each containing the appropriate vendor add-on and firmware add-on, and apply them to the respective hosts. This ensures consistent firmware updates while respecting vendor-specific packaging.

Answer

Use baseline groups to manage firmware separately.

Answer

Create a single cluster image that includes firmware for both vendors.

Answer

Manually update firmware using vendor tools, then use vLCM for ESXi updates.

Question 10

What is the default block size of a VMFS5 datastore?

Accepted Answer

1 MB. The default block size of a VMFS5 datastore is 1 MB. VMFS5 introduced a unified 1 MB block size that supports large files up to 2 TB minus 512 bytes, eliminating the need for multiple block sizes. This default applies to all VMFS5 datastores unless upgraded from VMFS3.

Answer

8 MB

Answer

2 MB

Answer

4 MB
