VCP-DCV vSphere Architecture, Products and Solutions Practice Test 2 — 15 Questions

Question 1

Match each vSphere component to its primary function.

Accepted Answer

vCenter Server: Centralized management platform for vSphere environments. The correct matches: vCenter Server is the centralized management platform; ESXi is the hypervisor; vSphere vMotion enables live migration; vSphere HA provides high availability. Common confusions include mixing up management functions with migration or HA features.

Answer

vCenter Server: Live migration of VMs without downtime

Answer

ESXi: High availability by restarting VMs on failed hosts

Question 2

Match each vSphere error/message to its meaning.

Accepted Answer

All Paths Down: All storage paths to a LUN are unavailable.. Correct matches: All Paths Down refers to storage path failure; Device or Resource Busy indicates resource contention; Not Enough Resources means insufficient CPU/memory; Permission Denied relates to authorization. Common confusions involve swapping definitions between All Paths Down and Device or Resource Busy, or between All Paths Down and Permission Denied.

Answer

All Paths Down: The device or resource is currently in use.

Answer

Permission Denied: All storage paths to a LUN are unavailable.

Question 3

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 4

An administrator notices that a VM with a critical application is experiencing intermittent network connectivity. The VM is configured with an E1000 vNIC. The ESXi host has been upgraded from 6.5 to 7.0. What is the most likely cause?

Accepted Answer

The VM hardware version needs to be upgraded to version 15.. The E1000 vNIC is a legacy emulated device that relies on the VM's hardware version for proper compatibility with newer ESXi releases. Upgrading the VM hardware version to version 15 (or later) ensures that the virtual hardware is aligned with ESXi 7.0's supported features and drivers, resolving intermittent network connectivity caused by outdated emulation.

Answer

The VM needs to be powered off and back on to reset the vNIC.

Answer

The E1000 vNIC is not supported in ESXi 7.0; VMXNET3 must be used.

Answer

The E1000 driver is incompatible with ESXi 7.0.

Question 5

A vSphere cluster using vSAN is experiencing high latency for some VMs. The administrator checks the vSAN skyline health and finds that all disk groups are healthy. Which additional step should the administrator take to diagnose the issue?

Accepted Answer

Check the vSAN performance service for object latency breakdown.. The vSAN Performance Service provides granular, real-time and historical metrics for vSAN objects, including latency breakdowns at the VM, disk group, and physical disk levels. Since the skyline health check shows all disk groups as healthy, the next logical step is to use the Performance Service to pinpoint whether the high latency is due to congestion on a specific object, such as a VM virtual disk or a particular disk group component, rather than a hardware failure.

Answer

Verify that the vSAN network is configured with jumbo frames.

Answer

Enable vSAN encryption to improve performance.

Answer

Increase the number of disk groups on each host.

Question 6

A vSphere administrator needs to ensure that a critical VM restarts automatically if the ESXi host fails. Which feature should be configured?

Accepted Answer

vSphere HA. vSphere HA provides host failure detection and automatic restart of VMs.

Answer

vSphere vMotion

Answer

vSphere DRS

Answer

vSphere Fault Tolerance

Question 7

An administrator is planning a vCenter Server deployment for a large environment with 15 ESXi hosts and 300 VMs. The environment requires high availability for vCenter Server. Which deployment topology should the administrator choose?

Accepted Answer

A VCSA configured with vCenter HA (active-passive).. vCenter HA (active-passive) provides automatic failover for the vCenter Server Appliance.

Answer

A Windows vCenter Server with a mirrored SQL database.

Answer

A single VCSA with an embedded database.

Answer

A VCSA deployed with an external Platform Services Controller.

Question 8

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.. If the dedicated vMotion network drops packets, vMotion will fail unless an alternate network is configured.

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 9

An administrator needs to migrate a running VM from one datastore to another without any downtime. Which vSphere feature allows this?

Accepted Answer

Storage vMotion. Storage vMotion migrates VM storage while the VM is running, with no downtime.

Answer

Cross vCenter vMotion

Answer

Storage DRS

Answer

vMotion

Question 10

A vSphere administrator deploys a new ESXi host and wants to ensure it is automatically added to a specific cluster and applies the correct host profiles. Which method should the administrator use?

Accepted Answer

Use Auto Deploy with stateful installations.. Auto Deploy with stateful installations provisions hosts and applies profiles automatically during network boot.

Answer

Use Clone Host functionality in vSphere Client.

Answer

Use Host Profiles to attach the profile to the cluster.

Answer

Use vCenter Server to add the host manually.

Question 11

Which TWO statements are true regarding vMotion requirements?

Accepted Answer

Both source and destination ESXi hosts must be licensed for vMotion.. VMotion requires both the source and destination ESXi hosts to have a vMotion license. Without this license, the vMotion feature is not enabled on a host, and the migration cannot be initiated. This is a fundamental licensing requirement enforced by vSphere.

Answer

The VM's virtual disks must be stored on shared storage.

Answer

Both hosts must be in the same cluster.

Answer

Both hosts must be in the same vCenter Server instance.

Question 12

Which TWO features are available only in the vSphere Enterprise Plus edition?

Accepted Answer

vSphere Fault Tolerance. vSphere Fault Tolerance (FT) is an Enterprise Plus exclusive feature that provides continuous availability for virtual machines by creating a secondary VM that runs in lockstep with the primary VM, using vLockstep technology to replicate CPU and memory state. This ensures zero data loss and zero downtime in the event of a host failure, but it requires the Enterprise Plus license tier because of the advanced resource management and coordination overhead.

Answer

Storage vMotion

Answer

vSphere HA

Answer

vSphere vMotion

Question 13

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

Question 14

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 15

Refer to the exhibit. An administrator runs the vmkfstools command on a VMFS datastore. Which information can be derived from the output?

Accepted Answer

The datastore ID is the file system UUID.. The output shows the file system UUID directly.

Answer

The datastore is formatted with VMFS version 6.82.

Answer

The datastore supports ESXi 6.5 and later.

Answer

The datastore has 1 TB capacity.
