VCP-DCV Practice Exam 3 — 20 Questions

Question 1

An administrator is managing a vSphere cluster with vSphere Lifecycle Manager baselines. Which THREE are valid baseline types? (Choose three.)

Accepted Answer

Patch baseline. In vSphere Lifecycle Manager, baselines are categorized into three valid types: Patch, Upgrade, and Extension. Option A (Patch baseline) is correct because patch baselines contain a collection of patches (VIBs) that can be applied to hosts to update or remediate them without changing the major ESXi version. Option C (Upgrade baseline) is correct because upgrade baselines contain an ESXi image that upgrades hosts to a new major version (for example, from ESXi 7 to ESXi 8). Option E (Extension baseline) is correct because extension baselines contain additional VIBs, such as third-party drivers or custom extensions, that are not part of the standard patch or upgrade process. Option B (Firmware baseline) is not a valid baseline type in vSphere Lifecycle Manager baselines; firmware updates are handled through firmware add-ons in desired-state images, not baselines. Option D (Critical Hosts baseline) is not a valid baseline type; there is no such baseline category in vSphere Lifecycle Manager.

Answer

Firmware baseline

Answer

Critical Hosts baseline

Question 2

An administrator sees that a vLCM remediation task for a host has failed with the error: 'The VIB is incompatible with the host's base image.' The host is using a custom image that includes a third-party driver. What is the most likely cause?

Accepted Answer

The VIB version is not compatible with the ESXi version in the image.. The error 'The VIB is incompatible with the host's base image' specifically indicates that the VIB's compatibility metadata does not match the ESXi base image version. vLCM validates each VIB against the base image's ESXi version and will reject any VIB whose acceptance level or version constraints are not satisfied. Since the host uses a custom image with a third-party driver, the most likely cause is that the driver VIB was built for a different ESXi version than the one in the image.

Answer

The third-party driver should be removed from the image.

Answer

The VIB is missing from the cluster image.

Answer

The administrator should ignore the error and proceed.

Question 3

A vSphere administrator wants to prevent users in a custom role from powering off virtual machines that have Fault Tolerance enabled. Which privilege must be removed from the custom role?

Accepted Answer

VirtualMachine.Interrupt.PowerOff. The privilege VirtualMachine.Interrupt.PowerOff directly controls the ability to power off a virtual machine, including those with Fault Tolerance enabled. Removing this privilege from a custom role prevents users from performing a power-off operation on any VM, including FT-protected ones. Other privileges like Suspend, Reset, or PowerOn do not govern the power-off action, so they are irrelevant to this requirement.

Answer

VirtualMachine.State.Suspend

Answer

VirtualMachine.Interrupt.Reset

Answer

VirtualMachine.Interrupt.PowerOn

Question 4

An administrator configures a VDS with two uplinks and sets the load balancing policy to 'Route based on IP hash'. What additional configuration is required on the physical switches to ensure proper traffic distribution?

Accepted Answer

Configure a static EtherChannel.. 'Route based on IP hash' on a vSphere Distributed Switch requires the physical switch ports to be configured as a static EtherChannel (or equivalent LAG). IP hash uses a hash of source and destination IPs to select an uplink, and the physical switch must treat the uplinks as a single logical link so return traffic flows correctly.

Answer

Use individual ports with no aggregation.

Answer

Set port security to allow multiple MAC addresses.

Answer

Enable Link Aggregation Control Protocol (LACP).

Question 5

An administrator notices that a virtual machine on an NFS datastore is experiencing intermittent performance degradation. The ESXi hosts are connected to the NFS server via a 10 GbE network. The administrator uses esxtop and sees high average latency on the storage device, but the NFS server reports low latency. What is the most likely cause?

Accepted Answer

Network congestion is causing TCP retransmissions. The most likely cause is network congestion causing TCP retransmissions. When the ESXi host sees high average latency on the NFS datastore but the NFS server reports low latency, it indicates that the delay is occurring in the network path between the host and the server, not on the server itself. TCP retransmissions due to network congestion would cause the host to experience higher latency than the server, matching the symptoms.

Answer

Jumbo frames are enabled on the ESXi hosts but not on the NFS server

Answer

The NFS server is performing data deduplication on the datastore

Answer

The NFS datastore is mounted with read-only permissions

Question 6

Refer to the exhibit. An ESXi 7.0 host is being configured for vSphere Trust Authority. The administrator runs the command shown and gets the output. What does this indicate?

Accepted Answer

The host does not have a TPM 2.0 chip, so vSphere Trust Authority cannot be used.. The output shows 'No TPM device found', which indicates that the ESXi 7.0 host does not have a TPM 2.0 chip installed or it is not detected by the system. vSphere Trust Authority (vTA) requires a TPM 2.0 chip on each ESXi host to establish hardware-based attestation and secure the trusted infrastructure. Without a TPM 2.0, the host cannot participate in vTA, making option C correct.

Answer

The TPM 2.0 device is present but not accessible.

Answer

The command is incorrect; the correct command is 'esxcli system visorfs tpm list'.

Answer

The host has a TPM 2.0 chip but it is not supported by ESXi.

Question 7

What is the maximum number of paths that vSphere supports for a single storage device?

Accepted Answer

32. vSphere supports up to 32 paths per storage device. 4 paths is common for some arrays, 8 is typical but not the maximum, and 256 is too high.

Answer

8

Answer

256

Answer

4

Question 8

An administrator observes that a VM with 4 vCPUs running on a host with hyperthreading enabled shows high %CSTP (co-stop) values in esxtop. What is a likely cause?

Accepted Answer

The VM has CPU affinity configured forcing vCPUs to specific pCPUs.. High %CSTP (co-stop) in esxtop indicates that the VM's vCPUs are waiting for each other to be co-scheduled on physical CPUs. CPU affinity forcing vCPUs to specific pCPUs can restrict the scheduler's ability to co-schedule all vCPUs simultaneously, leading to co-stop. This is a likely cause when a VM has multiple vCPUs and affinity constraints.

Answer

The VM's memory reservation is too high.

Answer

The host has deep C-states enabled causing CPU idle savings.

Answer

The host memory is overcommitted causing swapping.

Question 9

A company manages a vSphere cluster of 200 ESXi hosts using vSphere Lifecycle Manager baselines (baseline-based remediation). They decide to migrate to vLCM image-based management. The administrator selects one host as a reference host, generates a cluster image from it, and attempts to apply the image to the entire cluster. Most hosts remediate successfully, but 20 hosts fail with the error: "Image deployment failed: Error retrieving VIBs from repository." The failed hosts are all from a different hardware vendor than the reference host but are on the vSphere HCL. The administrator confirms that the repository URL is reachable from the failed hosts and that there are no network connectivity issues. What should the administrator do first to resolve the issue?

Accepted Answer

Check the vLCM cluster image for any components specific to the reference host's hardware that are not present in the failed hosts.. The error 'Error retrieving VIBs from repository' when applying a cluster image generated from a reference host indicates that the image contains hardware-specific VIBs (e.g., drivers, CIM providers) that are present on the reference host but not compatible with the failed hosts from a different hardware vendor. vLCM cluster images are derived from the reference host's software specification, including any vendor-specific components, and when applied to hosts lacking that hardware, the VIB retrieval fails because the repository does not contain matching VIBs for those hosts. The first step is to check the cluster image for such components and remove or replace them with hardware-independent versions to ensure compatibility across the heterogeneous cluster.

Answer

Reboot the failed hosts and retry the remediation.

Answer

Verify that the failed hosts have sufficient disk space in the /scratch partition.

Answer

Manually upload the required VIBs to the local depot on each failed host.

Question 10

A company is implementing vSphere 7.0 and wants to encrypt all vMotion traffic between ESXi hosts in a cluster. The cluster is not using any other encryption features. What is the minimum requirement to enable vMotion encryption?

Accepted Answer

The ESXi hosts must have a host profile applied with encryption enabled.. In vSphere 7.0, enabling vMotion encryption does not require Active Directory, a Key Management Server, Enhanced vMotion Compatibility (EVC), or host profiles. The minimum requirement is simply to configure the vMotion encryption policy on each ESXi host (set to 'Required' or 'Opportunistic'). No additional infrastructure or profiles are needed.

Answer

A VM Encryption Key Management Server must be configured.

Answer

The ESXi hosts must be joined to an Active Directory domain.

Answer

The cluster must be configured with Enhanced vMotion Compatibility (EVC).

Question 11

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?

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 12

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 13

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

Accepted Answer

Question 14

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 15

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 16

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 17

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 18

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 19

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 20

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
