VCP-DCV Practice Test 22 — 15 Questions

Question 1

A vSphere administrator is designing a cluster that must survive the loss of a single ESXi host without losing any VM data. The design uses vSAN as the primary datastore. Which storage policy setting must be configured to provide this level of protection?

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

Accepted Answer

Failures to tolerate set to 1. To survive the loss of one host, the vSAN storage policy must specify failures to tolerate of 1. This causes vSAN to maintain a redundant copy of each object, so if a host fails the remaining copy remains accessible. Striping, reservation, and a failures-to-tolerate value of 0 do not provide host-failure redundancy.

Answer

Number of disk stripes per object set to 1

Answer

Failures to tolerate set to 0

Answer

Object space reservation set to 100 percent

Question 2

A healthcare provider's vSphere 8 environment must encrypt all VM files at rest. The security team requires that encryption keys be stored on a hardware security module (HSM) and that the vCenter Server never hold the keys in its database. An administrator configures a Key Provider and enables VM encryption. Which component is responsible for storing the encryption keys?

Accepted Answer

The Key Management Server (KMS) configured as a standard key provider.. VM encryption requires a key provider to store keys externally. A standard key provider, typically a KMS with an HSM, holds the keys outside vCenter and ESXi. vCenter brokers key requests but does not store keys. The ESXi ramdisk is volatile, and Trust Authority handles attestation, not key storage. Thus, the KMS is the correct component.

Answer

The vCenter Server's VMware Postgres database.

Answer

The ESXi host's ramdisk, which persists across reboots.

Answer

A vSphere Trust Authority attestation service running on the ESXi host.

Question 3

A cloud operations team is evaluating vSphere editions for a new data center. The team needs features that allow live migration of running workloads between hosts and automated placement of workloads across a cluster based on resource usage. Which two vSphere capabilities provide these requirements? (Choose two.)

Accepted Answer

vSphere Distributed Resource Scheduler (DRS). vMotion provides live migration of running VMs between hosts, and DRS provides automated placement and balancing of workloads across a cluster based on resource usage. Together they meet both stated requirements. Storage I/O Control, Network I/O Control, and HA address storage performance, network performance, and failure recovery respectively, not live migration or automated placement.

Answer

vSphere High Availability (HA)

Answer

vSphere Network I/O Control

Answer

vSphere Storage I/O Control

Question 4

A vSphere administrator is configuring a vSphere Standard Switch on an ESXi host. The physical switch port is configured as a trunk allowing VLANs 10, 20, and 30. The administrator needs to ensure that virtual machine traffic tagged with VLAN 20 is properly isolated and that the ESXi host itself can communicate on VLAN 10 for management. Which configuration should the administrator apply to the port group used by the VMs?

Accepted Answer

Set the port group VLAN ID to 20.. The port group VLAN ID must match the desired VLAN for the VMs, which is 20. This ensures that traffic from VMs is tagged with VLAN 20 and isolated from other VLANs. Using None or All would not correctly tag the traffic, and using VLAN 10 would misplace the VMs. The physical switch trunk already allows VLAN 20, so the configuration aligns.

Answer

Set the port group VLAN ID to 0 (None).

Answer

Set the port group VLAN ID to 4095 (All).

Answer

Set the port group VLAN ID to 10.

Question 5

A vSphere administrator is responsible for a vLCM-managed cluster. The administrator needs to check whether the cluster's hosts match the desired image before performing remediation. Which vLCM feature provides this information?

Accepted Answer

Compliance check. The compliance check in vLCM compares each host's current state to the cluster's desired image and reports compliance status. It is the standard way to verify whether hosts match the desired image before remediation. Other features like pre-checks or HCL validation serve different purposes.

Answer

Remediation pre-check

Answer

Hardware compatibility list (HCL) validation

Answer

Image export

Question 6

A vSphere administrator needs to present a new Fibre Channel LUN to an ESXi host. The LUN is already zoned and visible to the host's HBA. Which action should the administrator take to make the datastore available for use?

Accepted Answer

Rescan the storage adapter in the vSphere Client.. To make a newly presented Fibre Channel LUN available, the administrator must rescan the storage adapter on the ESXi host. This can be done through the vSphere Client by navigating to the host's Storage Adapters and initiating a rescan. Once the rescan completes, the LUN appears and can be used to create a datastore. Creating the datastore without a rescan will not work because the LUN is not yet detected.

Answer

Create a new datastore and select the LUN from the list.

Answer

Reboot the ESXi host to detect the new LUN.

Answer

Run the esxcli storage core adapter rescan command from the host's DCUI.

Question 7

A vSphere administrator is using vSphere Lifecycle Manager (vLCM) to manage a cluster with a single image. After a recent hardware upgrade, one host in the cluster has a new network adapter that is not listed in the vSphere Compatibility Guide for the current ESXi version. The administrator attempts to remediate the cluster. What will happen?

Accepted Answer

The remediation will fail with an error indicating that the host hardware is not compatible with the image.. vLCM enforces hardware compatibility before remediation. A network adapter not on the vSphere Compatibility Guide for the target ESXi version causes the host to be non-compliant, and remediation fails with a compatibility error. The correct answer reflects this pre-check behavior.

Answer

The remediation will succeed, but the network adapter will be disabled until a compatible driver is installed.

Answer

The remediation will proceed, but the host will be marked as non-compliant after the update.

Answer

The remediation will succeed, and vLCM will automatically download and install the required driver from the internet.

Question 8

A vSphere administrator needs to ensure that a specific virtual machine's network traffic is isolated from all other virtual machines on the same ESXi host, even if they are on the same VLAN. Which vSphere networking feature should the administrator use?

Accepted Answer

Private VLANs (PVLANs) on a vSphere Distributed Switch. Private VLANs (PVLANs) on a vSphere Distributed Switch enable isolation of virtual machines at layer 2 by using secondary VLANs. This allows VMs on the same primary VLAN to be isolated from each other, which is not possible with standard VLAN tagging alone. NIOC, traffic shaping, and VLAN tagging do not provide this level of isolation.

Answer

Network I/O Control (NIOC) on a vSphere Distributed Switch

Answer

VLAN tagging on the virtual machine's vNIC

Answer

Traffic shaping on a standard switch port group

Question 9

An administrator is designing a vSphere 8 environment that will use vSphere Distributed Resource Scheduler (DRS) in a cluster. The administrator wants to ensure that DRS can automate the initial placement of virtual machines and provide recommendations for migration. Which two components are required for DRS to function? (Choose two.)

Accepted Answer

vCenter Server. DRS requires vCenter Server to manage the cluster and ESXi hosts with compatible CPUs for vMotion. vCenter Server provides the centralized management and automation, while CPU compatibility ensures that vMotion migrations can occur. vSphere HA, vDS, and vSAN are not prerequisites for DRS.

Answer

vSAN datastore

Answer

vSphere Distributed Switch (vDS)

Answer

vSphere High Availability (HA)

Question 10

A vSphere administrator is configuring Network I/O Control (NIOC) on a vSphere Distributed Switch. The administrator creates a new network resource pool named 'High Priority' and assigns it a shares value of 'High'. The administrator then assigns a VM's vNIC to a port group that uses this resource pool. However, the VM's traffic is not receiving the expected prioritization during congestion. What is a possible reason for this?

Accepted Answer

NIOC is not enabled on the vSphere Distributed Switch.. NIOC must be enabled on the vSphere Distributed Switch for network resource pools and shares to function. If NIOC is disabled, the shares values are ignored, and all traffic is treated equally. The other options are either unrelated to NIOC (VLAN, physical switch QoS) or misconceptions (reservations are not required for shares). Therefore, the administrator should verify that NIOC is enabled on the switch.

Answer

The VM's vNIC is not configured with a reservation.

Answer

The physical switch is not configured to trust CoS/DSCP tags.

Answer

The port group is not assigned to a VLAN.

Question 11

An administrator is configuring a vSAN cluster with a storage policy that uses RAID-5 erasure coding. The cluster has 6 hosts, each contributing capacity. The administrator sets the policy to 'Number of failures to tolerate' = 1. What is the minimum number of hosts required for this policy to be compliant?

Accepted Answer

4 hosts. For a vSAN storage policy using RAID-5 erasure coding with 'Number of failures to tolerate' set to 1, the minimum number of hosts required is 4. RAID-5 distributes data and parity across at least 4 fault domains (hosts), allowing the cluster to tolerate one host failure. With fewer than 4 hosts, the policy cannot be satisfied, and VMs would be non-compliant.

Answer

6 hosts

Answer

5 hosts

Answer

3 hosts

Question 12

A vSphere administrator is troubleshooting a virtual machine that cannot communicate on the network. The VM is connected to a port group on a vSphere Standard Switch. The administrator verifies that the physical switch port is configured as an access port for VLAN 10, and the port group VLAN ID is set to 10. The VM's guest OS has a static IP address in the correct subnet. Which step should the administrator take next to diagnose the issue?

Accepted Answer

Check the virtual machine's network adapter settings to ensure it is connected and the correct port group is selected.. The physical switch and port group VLAN configurations are correct. The next logical step is to verify the VM's network adapter settings, as a disconnected adapter or wrong port group is a common cause. Checking the adapter is non-disruptive and directly addresses the VM's connectivity. Other options involve changing correct configurations or taking unnecessary actions.

Answer

Change the port group VLAN ID to 4095.

Answer

Verify that the physical switch port is configured as a trunk.

Answer

Restart the management agents on the ESXi host.

Question 13

A financial services company runs a vSphere 8 environment with three clusters managed by a single vCenter Server. The security team mandates that all management traffic, including vMotion and vSAN, be isolated on dedicated VLANs. An administrator must verify which VMkernel adapters are configured for vMotion on each ESXi host. Which vSphere component provides this information in the vSphere Client?

Accepted Answer

The VMkernel adapters tab under the Networking section of each ESXi host. The VMkernel adapters tab is the authoritative place to see which services each VMkernel port has enabled, including vMotion. It shows the VLAN, IP address, and enabled services, allowing the administrator to confirm that vMotion is isolated on the correct VLAN across all hosts.

Answer

The Physical adapters tab under the Networking section of each ESXi host

Answer

The Host Profiles configuration for each ESXi host

Answer

The vSphere Distributed Switch topology diagram in the vSphere Client

Question 14

A vSphere administrator is managing a vLCM cluster with a desired image. The administrator needs to update the ESXi base image to a newer version. Before initiating remediation, the administrator wants to validate the image to ensure it is compatible with all hosts in the cluster. Which two actions should the administrator take to validate the image? (Choose two.)

Accepted Answer

Use the 'Validate Image' feature in the vLCM interface.. To validate a desired image before remediation, the administrator should use vLCM's 'Check Compliance' operation and the 'Validate Image' feature. These tools automatically check for compatibility, dependencies, and potential issues with the hosts, ensuring a smooth remediation process.

Answer

Manually compare the image's VIB list with each host's installed VIBs.

Answer

Export the image to an ISO and test it on a standalone host.

Answer

Check the vSphere Compatibility Guide for the ESXi version.

Question 15

An administrator is planning to upgrade a vSphere 7 environment to vSphere 8. The environment includes a vCenter Server Appliance 7.0 Update 3 and ESXi 7.0 Update 3 hosts. The administrator wants to minimize downtime and ensure the upgrade is supported. Which upgrade path should be used?

Accepted Answer

Upgrade vCenter Server to 8.0 first, then upgrade ESXi hosts to 8.0 using vSphere Lifecycle Manager.. The supported upgrade order is to upgrade vCenter Server first, then ESXi hosts. vCenter Server 8.0 can manage ESXi 7.0 hosts, allowing a phased upgrade. vSphere Lifecycle Manager is used to upgrade the hosts. Other options either violate upgrade order, cause unnecessary downtime, or use deprecated tools.

Answer

Use vSphere Update Manager to upgrade vCenter Server and ESXi hosts simultaneously.

Answer

Upgrade ESXi hosts to 8.0 first, then upgrade vCenter Server to 8.0.

Answer

Perform a fresh install of vCenter Server 8.0 and ESXi 8.0 on all hosts, then migrate VMs.
