VCP-DCV Practice Questions 2 — 50 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The hardware support manager (HSM) is not configured or the firmware baseline is outdated..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 If the HSM is not configured or the firmware baseline is outdated, vLCM cannot validate or update the firmware to match the ESXi image requirements, leading to a 'Non-Compliant' status and remediation failure.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

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

Question 11

A multinational corporation runs a vSphere environment with 100 ESXi hosts managed by a single vCenter Server. The security team mandates that all virtual machine disks (VMDKs) must be encrypted at rest. The administrator enables vSphere Virtual Machine Encryption and creates a Key Management Server (KMS) cluster. After encrypting a test VM, the VM powers on successfully, but the administrator notices that the VM's configuration files (VMX, NVRAM) are not encrypted. The security policy requires that all VM files, including configuration files, be encrypted. The administrator checks the VM storage policy and sees that the policy is set to 'VM Encryption Policy' with 'Disk Encryption' enabled. What should the administrator do to ensure the entire VM is encrypted?

Accepted Answer

Modify the VM storage policy to include encryption of VM home files. The VM storage policy 'VM Encryption Policy' with only 'Disk Encryption' enabled encrypts VMDK files but not the VM configuration files (VMX, NVRAM, logs, etc.). To encrypt all VM files, the storage policy must include the 'Encrypt VM home files' option, which applies encryption to the entire VM home directory on the datastore. This ensures compliance with the security mandate for full VM encryption at rest.

Answer

Enable encryption on the datastore where the VM resides

Answer

Add a second KMS cluster for redundancy

Answer

Enable vSphere Host Encryption on each ESXi host

Question 12

A company has multiple clusters with different hardware. They want to create separate vLCM images for each cluster. What is the best practice?

Accepted Answer

Create separate images for each cluster tailored to their hardware.. vLCM (vSphere Lifecycle Manager) images are cluster-scoped and must match the hardware compatibility of the hosts in that cluster. Because the company has multiple clusters with different hardware, the best practice is to create a separate image per cluster, tailoring the firmware add-on, driver add-on, and ESXi base image to that cluster's specific server models. This ensures HCL compliance and avoids remediation failures caused by incompatible drivers.

Answer

Create a single image that includes all possible components.

Answer

Use baseline groups instead of images.

Answer

Use Auto Deploy with a single image.

Question 13

A resource pool has the following configuration: CPU shares = 4000, reservation = 2 GHz, limit = 4 GHz. The parent cluster has 10 GHz total CPU capacity. Another resource pool contains VMs with higher shares. If both resource pools contend for CPU, which statement is TRUE?

Accepted Answer

The pool will receive at least 2 GHz and at most 4 GHz.. A resource pool's reservation guarantees a minimum CPU allocation (2 GHz) during contention, while the limit caps the maximum it can consume (4 GHz). Shares only determine relative priority when contention occurs — they do not guarantee an exact amount. Therefore the pool is guaranteed at least 2 GHz and can use up to 4 GHz.

Answer

The pool is guaranteed 4 GHz when contention occurs.

Answer

The reservation is ignored because a limit is set.

Answer

The pool will always receive exactly 4 GHz due to its shares.

Question 14

Based on the exhibit, what is the most likely cause of the remediation failure?

Accepted Answer

A firewall is blocking outbound HTTPS traffic to the internet.. A firewall blocking outbound HTTPS traffic to the internet would cause a connection timeout when vSphere Lifecycle Manager (vLCM) tries to reach the public VMware depot. This matches the error shown in the exhibit. Option A is incorrect because the local depot is not the source of the timeout; the issue is with external connectivity. Option B is incorrect because a DNS resolution failure would typically produce a 'Name or service not known' error, not a timeout. Option C is incorrect because if the vLCM service were not running, the error would likely indicate a service unavailability, not a network timeout.

Answer

The local depot is not configured.

Answer

The DNS server is unable to resolve depot.vmware.com.

Answer

The vLCM service is not running on vCenter.

Question 15

Which storage feature in vSphere allows a VM to be migrated from one datastore to another without any downtime?

Accepted Answer

Storage vMotion. Storage vMotion is the correct answer because it enables live migration of a virtual machine's virtual disk files from one datastore to another with zero downtime. It uses a mirrored copy mechanism where the source and destination datastores are synchronized before the VM is switched to the destination, ensuring continuous VM availability.

Answer

vMotion

Answer

Distributed Resource Scheduler (DRS)

Answer

Storage DRS

Question 16

Place the steps to create a new standard virtual switch in vSphere in order.

Accepted Answer

Select a host, then access networking, then click Add Networking, then choose the connection type, then create and configure the new standard switch.. The correct sequence for creating a new standard virtual switch in vSphere is: select a host, access its networking settings, click Add Networking, choose the connection type (e.g., Virtual Machine), and finally create and configure the new standard switch. This order ensures you follow the wizard's logical steps and avoid errors.

Answer

Select a host, then click Add Networking, then access networking, then choose the connection type, then create and configure the new standard switch.

Answer

Access networking, then select a host, then click Add Networking, then choose the connection type, then create and configure the new standard switch.

Answer

Select a host, then access networking, then choose the connection type, then click Add Networking, then create and configure the new standard switch.

Question 17

An administrator needs to configure a vSphere Standard Switch (vSS) for a small environment. Which component must be created first before adding a virtual machine to the network?

Accepted Answer

Create a standard switch.. Before a VM can be attached to a network on a vSphere Standard Switch, a standard switch must exist. The switch is the foundational layer; port groups and VMkernel interfaces are created on top of it. Therefore, creating the standard switch is the first required step.

Answer

Configure a VMkernel interface.

Answer

Create a virtual machine port group.

Answer

Add a physical uplink to the host.

Question 18

A vSphere administrator is troubleshooting a VM that is experiencing excessive disk latency. The VM is on a datastore accessed via NFS over a 1GbE network. The host shows high network utilization. Which action should be taken to improve performance?

Accepted Answer

Upgrade the network link to 10GbE or enable multiple NICs with teaming.. The VM is experiencing excessive disk latency due to high network utilization on the 1GbE link. Since NFS storage traffic is entirely network-bound, upgrading to 10GbE or enabling multiple NICs with teaming increases the available bandwidth, reduces congestion, and directly addresses the root cause of the latency. This is the most effective action because the bottleneck is at the network layer, not the storage protocol or VM configuration.

Answer

Enable Storage I/O Control on the datastore.

Answer

Convert the datastore from NFS to VMFS.

Answer

Increase the memory reservation for the VM.

Question 19

An administrator notices that after applying a vLCM image to a cluster, some hosts fail compliance with error: 'Host does not have required add-on'. What is the most likely cause?

Accepted Answer

The add-on is not present in the vLCM depot.. vLCM image compliance checks compare the host's installed software against the desired image, including base image, components, and add-ons. The error 'Host does not have required add-on' means the image references an add-on (e.g., a vendor add-on like NSX or a custom add-on) that is not available in the configured depot. Without the add-on in the depot, vLCM cannot remediate the host to match the image.

Answer

The vCenter license does not include vLCM.

Answer

The host is not in maintenance mode during the check.

Answer

The host does not have internet access to download the add-on.

Question 20

An administrator creates a DRS rule to separate two VMs (VM1 and VM2) using a 'Should' rule (separate VMs). After the rule is created, VM1 is manually vMotioned to a host that already runs VM2. What is the expected behavior?

Accepted Answer

VM1 remains on the host and a compliance violation is logged.. A 'Should' rule in DRS is a soft rule, meaning it is not strictly enforced. If an administrator manually vMotion's VM1 to a host running VM2, DRS will not automatically migrate it away; instead, it will log a compliance violation. The VM remains on the host, and the violation is recorded for review.

Answer

DRS automatically migrates VM1 to a compliant host.

Answer

The target host is placed into maintenance mode.

Answer

VM1 is powered off to prevent performance issues.
