VCP-DCV Practice Test 10 — 10 Questions

Question 1

A company has a vSphere environment with multiple clusters. The network team reports that a specific VLAN used for vMotion is intermittently dropping packets. What is the impact on vMotion operations?

Accepted Answer

vMotion will fail with an error.. vMotion requires a dedicated VMkernel adapter enabled for vMotion, and it does not fall back to the management network or any other interface if that specific network is unavailable or unreliable. When the vMotion VLAN is intermittently dropping packets, the vMotion process cannot maintain the reliable TCP connection needed to transfer the VM's memory state and device state, so the operation fails with an error. vSphere does not automatically reroute vMotion traffic to another network or degrade gracefully to a slower speed; it simply aborts the migration.

Answer

vMotion will use the management network as fallback.

Answer

vMotion will work but at a reduced speed.

Answer

vMotion will automatically switch to another available network.

Question 2

Which four types of traffic can be assigned to a separate VMkernel adapter on an ESXi host?

Accepted Answer

Management traffic. Management traffic (A) is a valid VMkernel service that can be enabled on a dedicated VMkernel adapter to isolate host management from other traffic. vMotion (B) is also a VMkernel service that can be assigned to its own VMkernel adapter to separate live migration traffic. vSAN (C) is a VMkernel service that can be enabled on a dedicated VMkernel adapter for vSAN storage communication. Fault Tolerance logging (E) is a VMkernel service that can be assigned to a separate VMkernel adapter for FT metadata traffic. Virtual machine network traffic (D) is not a VMkernel service; it is handled by standard or distributed virtual switches and port groups, not by a VMkernel adapter.

Answer

Virtual machine network traffic

Question 3

A company has a vLCM-managed cluster with a desired image that includes ESXi 8.0 U1 and multiple VIBs. After remediating, one host fails with an error: 'Failed to retrieve VIBs from depot'. What is the most likely cause?

Accepted Answer

The vCenter Server does not have internet access to the VMware depot.. The error 'Failed to retrieve VIBs from depot' indicates that vCenter Server cannot reach the depot from which the VIBs are sourced. In a vLCM-managed cluster using a desired image, the image specification includes VIBs that may be hosted on the VMware online depot or a local depot. If vCenter Server lacks internet access to the VMware depot, it cannot download the required VIBs, causing the remediation to fail. This is the most likely cause because the error is specifically about retrieval, not validation or compatibility.

Answer

The cluster has a baseline attached that conflicts with the desired image.

Answer

The image validation failed due to incompatible VIBs.

Answer

The host firmware is not compatible with the selected VIBs.

Question 4

An administrator wants to limit the amount of CPU resources a single VM can consume in a vSphere cluster. Which feature should be used?

Accepted Answer

CPU limit. A CPU limit sets an upper bound on the amount of physical CPU resources a VM can consume, expressed in MHz. When the VM reaches the limit, it is throttled even if the host has idle capacity. This directly addresses the requirement to cap a single VM's CPU consumption.

Answer

CPU affinity

Answer

CPU reservation

Answer

Resource pools

Question 5

Refer to the exhibit. The performance data shows MEMCTL at 5% and SWPOUT at 2%. What does this indicate about the host?

Accepted Answer

The host is over-committed on memory, causing ballooning and swapping.. MEMCTL at 5% indicates the ESXi host's memory balloon driver (vmmemctl) is actively reclaiming memory from virtual machines, while SWPOUT at 2% shows the host is swapping guest memory to disk. Together, these values confirm the host is over-committed on memory, forcing the hypervisor to use both ballooning and swapping to free up memory for VMs.

Answer

The host is experiencing CPU contention.

Answer

The host has network congestion.

Answer

The host has high storage latency.

Question 6

A company runs a vSphere cluster with vSphere Distributed Resource Scheduler (DRS) enabled in fully automated mode. The operations team wants to add a new ESXi host to the cluster without causing any VM downtime. Which statement describes what happens to the running workloads when the host is added?

Accepted Answer

Running VMs continue without interruption, and DRS may use vMotion to rebalance them onto the new host if needed.. When a host joins a DRS-enabled cluster, running VMs are unaffected. In fully automated mode DRS can perform vMotion migrations to place workloads on the new host if doing so improves balance, and live migration keeps those VMs available. No power-off, re-registration, or maintenance mode step is involved in normal cluster expansion.

Answer

All VMs must be powered off and registered again on the new host before the cluster recognizes it.

Answer

DRS immediately migrates all VMs to the new host to balance the cluster.

Answer

The new host remains in maintenance mode until an administrator manually evacuates it.

Question 7

A vSphere administrator manages a cluster where several business-critical VMs must remain available even if an entire ESXi host fails. The administrator configures vSphere High Availability (HA) with host monitoring and admission control enabled, but the VMs are not configured with any restart priority. During a host failure, what is the default behavior for these VMs?

Accepted Answer

The VMs are restarted on surviving hosts according to the cluster's default VM restart priority.. vSphere HA uses a cluster-level default restart priority when a VM has no individual setting. After detecting a host failure, the master host applies admission control and restarts the affected VMs on surviving hosts automatically. No per-VM priority, manual approval, or pre-failure vMotion is required for the VMs to be protected.

Answer

The VMs are not restarted because HA requires an explicit restart priority for every VM.

Answer

The VMs are restarted only after an administrator manually approves the restart in the vSphere Client.

Answer

The VMs are migrated with vMotion to surviving hosts before the failed host goes down.

Question 8

A company has a vSphere cluster of eight ESXi hosts managed by a single vCenter Server. They need to apply a critical security patch to the ESXi hosts with minimal downtime. Which method should the administrator use?

Accepted Answer

Put each host in maintenance mode and apply the patch via Update Manager.. VSphere Update Manager (VUM) automates the patching process by placing each host into maintenance mode, migrating VMs via vMotion to other hosts, applying the patch, and then bringing the host back online—all with minimal downtime. This is the recommended method for applying critical security patches to multiple ESXi hosts in a cluster managed by a single vCenter Server.

Answer

Use vMotion to migrate all VMs to one host, apply patch, then move back.

Answer

Use vSphere vMotion to migrate VMs, then apply patch using CLI on each host.

Answer

Schedule a host reboot during maintenance window and apply patch via ISO boot.

Question 9

A company uses vSphere 7.0 with two ESXi hosts in a cluster. All virtual machines (VMs) are stored on a VMFS6 datastore backed by a single LUN from a mid-range SAN. The LUN is presented to both hosts and both hosts have identical multipathing configuration. Recently, an administrator noticed that one host shows the datastore as "Inactive" while the other host can access it normally. The administrator verifies that both hosts have connectivity to the SAN, the LUN is visible to both hosts, and the storage array reports the LUN as online. The administrator wants to restore access to the datastore on the affected host without disrupting VMs running on the other host. Which action should the administrator take?

Accepted Answer

Perform a storage rescan on the affected host.. The datastore showing as 'Inactive' on one host while remaining accessible on the other indicates a path failure or a transient storage connectivity issue at the host level, not a permanent problem with the LUN or array. Performing a storage rescan on the affected host forces the ESXi host to re-evaluate all storage paths and re-register the datastore, restoring access without impacting VMs on the other host. This is the safest and least disruptive action because it does not require a reboot, multipathing policy change, or unmounting the datastore.

Answer

Reboot the affected ESXi host.

Answer

Change the multipathing policy on the affected host to Round Robin.

Answer

Unmount the datastore from the affected host and then remount it.

Question 10

During a vLCM health check, an administrator sees that the health status for a cluster is 'Error' with the message: 'Unable to connect to the depot service at https://depot.vmware.com'. The cluster is configured to use the online depot. What is the most likely cause?

Accepted Answer

A firewall is blocking outbound HTTPS access to the internet.. The most likely cause is that a firewall is blocking outbound HTTPS access to the internet, preventing vCenter from reaching the VMware depot at https://depot.vmware.com. The error message explicitly indicates a connection failure to the depot service, and since the cluster uses the online depot, outbound connectivity is required. Firewall rules blocking port 443 are a common cause in secured environments.

Answer

DNS resolution is failing for the vCenter server.

Answer

The vCenter server's certificate is expired.

Answer

The cluster image has an invalid URL.
