VCP-DCV Practice Test 13 — 15 Questions

Question 1

A vSphere cluster has 10 ESXi hosts configured with vSphere DRS. The administrator wants to ensure that a group of VMs running a latency-sensitive application are always placed on the same host. Which DRS rule should be created?

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

Accepted Answer

VM-VM affinity rule with a 'must run on the same host' constraint.. A VM-VM affinity rule with the 'must run on the same host' constraint is the only DRS rule type that guarantees the specified VMs are co-located on a single ESXi host. This is exactly what a latency-sensitive application requiring inter-VM communication on the same physical host needs, since it eliminates network hops between hosts. The 'must' (required) constraint makes DRS treat the rule as mandatory, preventing any placement that would separate the VMs.

Answer

VM-to-Host affinity rule with a 'should run on hosts in group' constraint.

Answer

VM-VM affinity rule with a 'should run on the same host' constraint.

Answer

VM-VM anti-affinity rule with a 'separate VMs' constraint.

Question 2

Based on the exhibit, if a host in the cluster has a network card that is not on the vSphere Compatibility Guide, what will happen during remediation?

Accepted Answer

The remediation will fail for that host.. During remediation (e.g., vSphere Lifecycle Manager or Update Manager), if a host has a network card not on the vSphere Compatibility Guide, the remediation will fail for that host. vSphere validates hardware compatibility before applying updates; an incompatible device causes the host to be placed in a failed state for that remediation task.

Answer

The host will automatically update its drivers to become compatible.

Answer

A warning will be generated but remediation proceeds.

Answer

The host will be skipped with a warning.

Question 3

An administrator needs to expand a VMFS5 datastore that is currently 2 TB in size. The underlying LUN is 5 TB. What is the maximum size the datastore can be expanded to without involving additional LUNs?

Accepted Answer

5 TB. VMFS5 supports datastore sizes up to 64 TB, but the datastore cannot exceed the size of its underlying LUN. Since the LUN is 5 TB, the maximum the datastore can be expanded to without adding LUNs is 5 TB.

Answer

64 TB

Answer

4 TB

Answer

2 TB

Question 4

A vSphere environment uses an iSCSI storage array with multiple targets. The administrator configures CHAP authentication but some hosts fail to connect. The working hosts are configured with mutual CHAP, while the failing hosts use only one-way CHAP. What is the most likely reason for the failures?

Accepted Answer

The storage array requires mutual CHAP, but the failing hosts are configured for one-way CHAP.. Mutual CHAP requires the target to authenticate the initiator and the initiator to authenticate the target. If the storage array is configured to require mutual CHAP, hosts using only one-way CHAP will fail to complete the authentication handshake. The working hosts are configured with mutual CHAP, confirming the array enforces mutual authentication.

Answer

The CHAP secret is not set on the failing hosts.

Answer

The iSCSI target name is incorrect on the failing hosts.

Answer

The storage array is configured to use only one-way CHAP.

Question 5

An administrator notices that a VM with high I/O demands is experiencing performance issues because other VMs on the same datastore are consuming too many I/O operations. Which feature can be used to guarantee a minimum I/O share to this VM?

Accepted Answer

Storage I/O Control shares. Storage I/O Control shares allow you to guarantee a minimum I/O share to a VM by assigning shares to its virtual disks. When contention occurs, ESXi enforces these shares to ensure the VM gets its fair share of I/O resources.

Answer

Multipathing policy

Answer

VM storage policy

Answer

Storage DRS

Question 6

An ESXi host has an NFS datastore mounted from a NAS array. The administrator wants to enable hardware acceleration (VAAI) for the datastore. Which requirement must be met?

Accepted Answer

The NAS array must support NFSv3 and VAAI primitives. VAAI (vStorage APIs for Array Integration) for NFS requires the NAS array to support NFSv3 and the specific VAAI primitives for NFS, such as Full File Clone, Fast File Clone, Reserve Space, and Extended Statistics. ESXi detects these primitives via the array's NFSv3 protocol extensions and enables hardware acceleration for operations like clone and snapshot. Without array support for these primitives, VAAI cannot be enabled.

Answer

The NAS array must present the LUN as an iSCSI target

Answer

The datastore must be formatted as VMFS6

Answer

The ESXi host must have a software FCoE adapter configured

Question 7

Which tool provides real-time performance monitoring at the ESXi host level, including CPU, memory, network, and storage metrics?

Accepted Answer

esxtop. esxtop is a command-line tool that provides real-time host performance data. vCenter performance charts are historical. resxtop is for remote usage, and dcli is a different tool.

Answer

dcli

Answer

resxtop

Answer

vCenter performance charts

Question 8

Order the steps to take a snapshot of a virtual machine.

Accepted Answer

Initiate snapshot, name it, choose memory and quiesce options, then confirm.. The correct order for taking a snapshot in VMware vSphere is to first initiate the snapshot by right-clicking the VM and selecting 'Snapshot > Take Snapshot', then in the dialog provide a name and optional description, select whether to snapshot the virtual machine's memory and whether to quiesce the file system, and finally confirm by clicking OK. This sequence ensures that all necessary parameters are set before the snapshot is created.

Answer

Initiate snapshot, choose memory and quiesce options, name it, then confirm.

Answer

Name the snapshot, initiate snapshot, choose memory and quiesce options, then confirm.

Answer

Initiate snapshot, confirm, then name it and choose memory and quiesce options.

Question 9

An administrator is using vSphere Lifecycle Manager (vLCM) to manage a cluster with an image. The administrator wants to add a custom VIB from a third-party vendor to the image. What must be done first?

Accepted Answer

Import the VIB into the vLCM depot and add it as a component to the image.. To include a custom VIB in a vLCM image, the VIB must first be imported into the vLCM depot. Once in the depot, it can be added as a component to the image. This ensures that the VIB is part of the desired state and will be applied during remediation. Manual installation or baselines are not appropriate when the cluster is image-managed.

Answer

Create a baseline containing the VIB and attach it to the cluster alongside the image.

Answer

Use vSphere Client to upload the VIB to each host's /tmp directory and reboot.

Answer

Install the VIB manually on each host using esxcli, then remediate the cluster.

Question 10

A company has a vSphere cluster with 10 ESXi hosts managed by vLCM. They use a custom image that includes a third-party network driver. After updating the image to include a new version of the driver, remediation fails on all hosts with the error: 'The software specification contains a VIB that is not compatible with the host platform.' What is the most likely cause?

Accepted Answer

The new driver VIB is not compatible with the ESXi version in the image.. The error 'The software specification contains a VIB that is not compatible with the host platform' indicates that the VIB (vSphere Installation Bundle) in the custom image is not designed to run on the ESXi version specified in the image. vLCM validates VIB compatibility against the ESXi base image version, and a third-party driver VIB must be built for that exact ESXi build. Since the new driver version is incompatible with the ESXi version, remediation fails on all hosts.

Answer

The vLCM image depot is corrupted.

Answer

The hosts have incompatible firmware.

Answer

The custom image is not signed by VMware.

Question 11

A vSphere administrator is trying to create a custom ESXi image for a cluster using vSphere Lifecycle Manager. The cluster contains hosts with a specific hardware that requires a third-party component (e.g., a NIC driver). The administrator adds the component to the image definition in vLCM. However, when applying the image, the component does not get installed on the hosts. What is the likely cause?

Accepted Answer

The component version is not compatible with the ESXi version in the image.. In vSphere Lifecycle Manager (vLCM), a custom ESXi image is composed of a base ESXi version plus additional components (drivers, firmware). Each component has a compatibility matrix that specifies which ESXi versions it supports. If the component version added to the image definition is not compatible with the ESXi version in the image, vLCM will not install it during remediation — the component is effectively ignored or the image fails validation. This is the most likely cause when a component silently does not get installed.

Answer

The administrator did not mount the component ISO during remediation.

Answer

The component is not signed by a trusted certificate authority.

Answer

The component must be installed manually on each host first.

Question 12

Which THREE are valid components of a vLCM single image? (Choose three.)

Accepted Answer

Additional VIBs and components. In vSphere Lifecycle Manager (vLCM), a single image is a declarative, cluster-level software specification that includes the ESXi base image (the ESXi version and build number, option C), additional VIBs and components layered on top of that base image (option B), and the firmware and driver add-ons delivered through hardware support managers (option E). Option C is correct because the base image defines the exact ESXi version and build the hosts will run. Option B is correct because components and additional VIBs are explicitly part of the image payload beyond the base ESXi image. Option E is correct because firmware and driver versions are managed as part of the image via firmware add-ons and hardware support managers. Option A is not part of a vLCM image, since VM hardware versions are per-VM settings unrelated to host image management. Option D is not part of a vLCM image, because vCenter Server version is managed separately from the ESXi cluster image.

Answer

Virtual machine hardware versions

Answer

vCenter Server version

Question 13

A VM cannot connect to the network after being migrated to a different host in the cluster. The VM's network adapter is connected to a standard switch port group that exists on the source host but not on the destination host. What is the most likely cause?

Accepted Answer

The standard switch is not configured on the destination host.. A standard vSwitch and its port groups are host-local objects — they are not shared across ESXi hosts in a cluster. If the VM's port group exists only on the source host, the destination host has no matching port group, so the VM's network adapter cannot connect after migration. This is the classic cause of post-migration network loss with standard switches.

Answer

The VM's MAC address is not allowed on the destination port group.

Answer

The VLAN ID on the port group does not match.

Answer

The ESXi host's firewall is blocking the VM's traffic.

Question 14

Which TWO capabilities are exclusive to vSphere with Tanzu compared to standard vSphere clusters?

Accepted Answer

Tanzu Kubernetes Grid Service. Options B and C are correct. vSphere with Tanzu provides a native Kubernetes control plane and the Tanzu Kubernetes Grid Service for managing Kubernetes workloads, which are not available in standard vSphere clusters. A (DRS and HA) and D (vMotion) are general vSphere features, not exclusive to vSphere with Tanzu. E (vSAN storage policies) is a vSAN capability, not exclusive to vSphere with Tanzu.

Answer

DRS and HA

Answer

vMotion

Answer

vSAN storage policies

Question 15

Which THREE components are part of a vSAN cluster?

Accepted Answer

vSAN datastore. A vSAN datastore is a core component of a vSAN cluster because it is the aggregated, distributed storage object created from the local disks of the ESXi hosts in the cluster. This datastore is what VMs use for storage, and it is built and managed by the vSAN layer, making it an integral part of the cluster's architecture.

Answer

vSAN witness host

Answer

vCenter Server
