VCP-DCV Practice Test 4 — 10 Questions

Question 1

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?

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

Accepted Answer

A VCSA configured with vCenter HA (active-passive).. vCenter HA (active-passive) is the native, supported high-availability solution for VCSA, providing automatic failover between an active, passive, and witness node. For a large environment (15 hosts, 300 VMs) requiring vCenter HA, this topology ensures minimal downtime and is the recommended approach in modern vSphere versions.

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 2

A vSphere administrator is deploying VMs on a vSAN cluster with 6 hosts. Each host has two disk groups, each with one cache SSD and four capacity SSDs. The administrator applies a storage policy using RAID 5 erasure coding with Number of failures to tolerate set to 1. After some time, the administrator notices that several VMs are showing compliance status as 'Non-compliant'. Investigating further, the administrator finds that on one host, the cache SSD of the first disk group has failed. The capacity SSDs in that disk group are still functional. The vSAN cluster still has sufficient overall capacity and the health service shows no other issues. What is the most likely reason for the VMs' non-compliance?

Accepted Answer

The failed cache device makes the entire disk group unavailable, so components on that disk group are inaccessible.. A failed cache device renders the entire disk group non-operational; any VM components on that disk group become inaccessible, causing non-compliance. Option A is incorrect because cache capacity is not a compliance factor. Option B is incorrect because loss of a single cache device does not remove a fault domain. Option C is incorrect because the number of hosts with cache devices is still sufficient.

Answer

The failed cache device reduces the overall cache capacity, causing the policy to be violated.

Answer

The vSAN cluster has lost a fault domain due to the failed cache device.

Answer

The RAID 5 policy requires a minimum of 4 hosts with cache devices, and now only 5 are available.

Question 3

An administrator notices that HTTP connections to the ESXi host are timing out frequently. Based on the exhibit, which configuration change would most likely resolve the issue?

Accepted Answer

Increase maxKeepAliveTimeout to a higher value, such as 180. Increasing maxKeepAliveTimeout to a higher value, such as 180, would most likely resolve the issue of HTTP connections timing out frequently. The maxKeepAliveTimeout setting controls how long the ESXi host's reverse proxy (rhttpproxy) keeps an HTTP connection open for keep-alive requests. If it is too low, connections may time out prematurely, causing frequent timeouts. Increasing it allows longer-lived connections.

Answer

Restart the rhttpproxy service

Answer

Set useProxy to true and specify a proxy server

Answer

Set maxKeepAliveTimeout to 0 to disable keepalive

Question 4

Sequence the steps to configure a VM to use a static IP address via vSphere's customization specification.

Accepted Answer

Initiate customization, then select or create a customization specification, then configure the IP settings within the specification, then apply the customization, then power on the VM.. The correct sequence ensures that the VM receives the static IP configuration during the first boot after customization. Initiating the customization opens the wizard, selecting or creating a spec defines the settings, configuring IP within the spec sets the static address, applying saves the configuration, and powering on triggers the OS customization process.

Answer

Initiate customization, then configure IP settings, then select or create a customization specification, then apply, then power on.

Answer

Power on the VM, then initiate customization, then select or create a specification, then configure IP, then apply.

Answer

Initiate customization, then select or create a specification, then apply, then configure IP, then power on.

Question 5

An administrator wants to use vLCM to manage firmware for a cluster of Dell PowerEdge servers. What is required?

Accepted Answer

vCenter Server with vLCM and hardware support manager (HSM). To use vLCM to manage firmware for a cluster of Dell PowerEdge servers, you need vCenter Server with vLCM and a hardware support manager (HSM). The HSM is a vSphere Installation Bundle (VIB) provided by the hardware vendor (in this case, Dell) that integrates with vLCM to provide firmware updates. Dell's HSM is typically delivered as part of the Dell OpenManage integration, but the core requirement is the HSM plugin registered with vLCM.

Answer

Manual download of firmware ISOs

Answer

Dell OpenManage Enterprise

Answer

vSphere Update Manager baseline

Question 6

A large financial institution runs a vSphere 7.0 environment with 100 ESXi hosts and 2,000 VMs. The security team has identified that several VMs are vulnerable to a critical side-channel attack that requires disabling hyperthreading on the ESXi hosts. The administrator needs to implement a solution that minimizes performance impact while ensuring compliance. The environment uses DRS clusters with varying workloads: some VMs are CPU-intensive (financial modeling) and others are memory-bound (database servers). The administrator cannot afford to take hosts offline for maintenance during business hours. The change must be implemented within 48 hours. Which course of action should the administrator take?

Accepted Answer

Place each host in maintenance mode individually, disable hyperthreading in the host BIOS, reboot the host, and then move to the next host. Rebalance VMs after all hosts are updated.. Disabling hyperthreading to mitigate side-channel attacks (e.g., L1TF or MDS) requires a host BIOS change, which necessitates a reboot. The only supported method in vSphere 7.0 is to place each host into maintenance mode, change the BIOS setting, reboot, and then repeat for all hosts. This approach minimizes performance impact by allowing VMs to be migrated via vMotion and avoids simultaneous downtime, meeting the 48-hour requirement without taking all hosts offline during business hours.

Answer

Use a vSphere DRS rule to disable hyperthreading for all VMs in the cluster, avoiding the need to modify host BIOS.

Answer

Delay the change and schedule a maintenance window for the next month when business impact is lower.

Answer

Disable hyperthreading on all hosts simultaneously using a vSphere Cluster feature, then reboot all hosts at once during off-peak hours.

Question 7

After upgrading the physical switches, the LAG (Link Aggregation Group) on a VDS does not come up. The VDS LAG configuration shows LACP active mode. The physical switch ports are configured with LACP active mode as well. What is the most likely cause?

Accepted Answer

The physical switch ports are not in a port-channel. For a VDS LAG in LACP active mode to come up, the physical switch ports must be configured as a port-channel (LAG) with LACP enabled. If the switch ports are left as individual access ports without a port-channel, the ESXi host's LACP PDUs are not matched to a LAG on the switch side, and the LAG never forms. This is the most common cause after a switch upgrade where the port-channel configuration was not reapplied.

Answer

The physical switch uses a different LACP system priority

Answer

The ESXi hosts have different LAG IDs

Answer

The VDS LAG hashing algorithm is set to IP hash

Question 8

Refer to the exhibit. The vSphere administrator observes that vm1 has a %RDY value of 20.5. What is the most likely cause of this high ready time?

Accepted Answer

The host's physical CPUs are overcommitted. %RDY (ready time) measures the percentage of time a VM's virtual CPUs are ready to run but cannot be scheduled onto a physical CPU because the host's pCPUs are busy. A sustained value of 20.5% indicates significant CPU contention, meaning the host's physical cores are overcommitted relative to the total vCPU demand of all powered-on VMs. This is a classic symptom of CPU over-subscription on the ESXi host.

Answer

The VM is experiencing network packet loss

Answer

The VM's virtual disk is causing I/O latency

Answer

Insufficient memory is allocated to vm1

Question 9

Which feature allows a VM to use storage directly from the host's local disks, pooled across a cluster?

Accepted Answer

vSAN. vSAN is VMware's software-defined storage solution that pools local disks (SSDs/HDDs) from ESXi hosts across a cluster into a shared datastore. It allows VMs to use storage directly from host local disks, aggregated and presented as a single distributed datastore. This matches the requirement exactly.

Answer

VMFS

Answer

vFlash

Answer

NFS

Question 10

A vSphere administrator wants to ensure that all ESXi hosts in a cluster boot from a consistent set of software packages, including firmware and drivers. Which vSphere feature should be used to achieve this?

Accepted Answer

vSphere Lifecycle Manager (vLCM) with a single image. vSphere Lifecycle Manager (vLCM) with a single image is the correct choice because it allows the administrator to define a complete software specification—including ESXi version, firmware, drivers, and add-ons—as a single desired state image. When applied to a cluster, vLCM ensures every ESXi host boots from exactly the same set of software packages, eliminating drift and guaranteeing consistency across all hosts.

Answer

vSphere Update Manager (VUM)

Answer

Host Profiles

Answer

Quick Boot
