VCP-DCV Practice Test 12 — 15 Questions

Question 1

An administrator is configuring a distributed switch with LACP. Which two statements are true regarding LACP support on vSphere distributed switches? (Choose two.)

Accepted Answer

LACP supports both active and passive modes.. Option A is correct because vSphere distributed switches support LACP in both active and passive modes, allowing the ESXi host to either initiate LACPDU negotiation (active) or respond to the physical switch's negotiation (passive). Option D is correct because LACP on a vSphere distributed switch requires creating a Link Aggregation Group (LAG), which is then bound to a distributed port group or uplink port group to aggregate multiple uplinks. Option B is incorrect because IP hash is a static NIC teaming load-balancing policy, not an LACP behavior; LACP uses a dynamic link aggregation hashing scheme. Option C is incorrect because LACP is only supported on vSphere distributed switches, not on standard vSwitches. Option E is incorrect because LACP LAGs can carry management, vMotion, and VM traffic, not just virtual machine traffic.

Answer

LACP automatically distributes traffic based on IP hash.

Answer

LACP can be configured on standard vSwitches.

Answer

LACP is only supported for virtual machine traffic, not for management or vMotion.

Question 2

Refer to the exhibit. An administrator attempts to add a host to a vSAN cluster and receives this error. Which step should the administrator take to resolve the issue?

Accepted Answer

Create a new VMkernel adapter (vmk3) on the host's network and enable vSAN traffic.. vSAN requires a dedicated VMkernel adapter with the vSAN traffic service enabled, and the error indicates no such adapter exists on the host. Creating a new vmk3 and enabling vSAN traffic on it satisfies the prerequisite without disturbing existing management or vMotion traffic.

Answer

Reconfigure the vMotion interface (vmk1) to also carry vSAN traffic.

Answer

Add the host to the cluster without vSAN and enable vSAN later.

Answer

Enable vSAN traffic on the existing vmk0 interface.

Question 3

An administrator wants to ensure that no user can view or modify VMs in a particular folder except the folder owner. What is the proper method to achieve this?

Accepted Answer

On the folder, assign permissions to the folder owner with the desired role and ensure propagation is set to 'All children'.. To restrict access so only the folder owner can view or modify VMs in a folder, you assign the owner the desired role on the folder and set propagation to 'All children'. This ensures the permission is inherited by all VMs and sub-objects within the folder, giving the owner the necessary rights while others without explicit permissions are denied by default.

Answer

Use the No Access permission on the folder for all other users.

Answer

Assign the folder owner with Administrator role on the folder.

Answer

Create a global role that denies access to all VMs except the folder owner.

Question 4

Match each vSphere feature to its correct description.

Accepted Answer

vMotion: Enables live migration of running virtual machines with zero downtime. Key vSphere features: vMotion (live migration), HA (automatic restart), DRS (load balancing), FT (continuous availability via lockstep). Common confusions involve swapping the feature and its description.

Answer

vMotion: Provides automatic restart of VMs after host failure

Answer

HA: Enables live migration of running VMs

Question 5

An administrator needs to migrate a VM from a VMFS5 datastore to a vSAN datastore while preserving the storage policy. Which migration method should be used?

Accepted Answer

Storage vMotion. Storage vMotion migrates a VM's virtual disks from one datastore to another while the VM remains powered on, and it preserves the VM's storage policy (e.g., vSAN storage policy). It is the correct method for moving a VM between datastores without downtime.

Answer

Cold migration

Answer

Clone

Answer

vMotion

Question 6

An administrator is troubleshooting a failed attempt to add an ESXi host to a vCenter Server domain. The error message states: 'The host's certificate has been tampered with or is invalid.' What is the most likely cause?

Accepted Answer

The ESXi host's certificate thumbprint does not match the thumbprint stored in vCenter Server.. The error 'The host's certificate has been tampered with or is invalid' occurs when the ESXi host presents a certificate whose thumbprint does not match the thumbprint that vCenter Server has stored for that host. This mismatch can happen if the host's certificate was replaced (e.g., due to a reinstall or manual rotation) without updating the vCenter Server's trusted store. vCenter Server verifies the host's identity by comparing the SHA-1 or SHA-256 thumbprint of the presented certificate against its stored record; a mismatch triggers this specific error.

Answer

The vCenter Server's account lockout policy has been triggered.

Answer

The ESXi host's SSH keys have been rotated.

Answer

The ESXi host's certificate has expired.

Question 7

What is the purpose of the vLCM hardware compatibility check?

Accepted Answer

Check if hardware is on HCL. The vLCM hardware compatibility check validates that the host's physical hardware (CPU, storage controllers, NICs, HBAs) is listed on the VMware Hardware Compatibility List (HCL) for the target ESXi version. This ensures the image being applied is supported on that hardware, preventing unsupported configurations that could cause instability or void support.

Answer

Verify ESXi build

Answer

Check storage performance

Answer

Validate network drivers

Question 8

Sequence the steps to configure a DRS rule that keeps two VMs on different hosts.

Accepted Answer

Access cluster configuration, then add a new DRS rule, then provide a name for the rule, then select 'Separate VMs' as the type, then assign the two VMs.. The correct sequence to configure a DRS rule that keeps two VMs on different hosts is: first access the cluster configuration, then add a new DRS rule, then name the rule, then choose the 'Separate VMs' type to enforce host separation, and finally assign the two VMs. This order ensures that each step logically follows the previous one, adhering to the typical workflow in vSphere where the rule is created before its properties are defined and applied.

Answer

Access cluster configuration, then add a new DRS rule, then select 'Separate VMs' as the type, then assign the two VMs, then provide a name for the rule.

Answer

Access cluster configuration, then provide a name for the rule, then add a new DRS rule, then select 'Separate VMs' as the type, then assign the two VMs.

Answer

Access cluster configuration, then add a new DRS rule, then assign the two VMs, then provide a name for the rule, then select 'Separate VMs' as the type.

Question 9

An administrator is planning to decommission a vSphere cluster that currently uses baseline-based lifecycle management. They want to adopt image-based management for a new cluster. Which action must be taken to ensure a clean migration?

Accepted Answer

Create a new cluster with image-based management.. Image-based lifecycle management in vSphere Lifecycle Manager (vLCM) is a cluster-level construct; a cluster is either baseline-based or image-based, and you cannot convert an existing baseline-managed cluster in place. To adopt image-based management, you must create a new cluster configured for image-based management and then move hosts into it.

Answer

Manually recreate the baselines as images in the new cluster.

Answer

Assign host profiles to the new cluster to enforce configuration.

Answer

Export the existing baseline group and import it into the new cluster.

Question 10

Refer to the exhibit. An administrator configures a claim rule to use VMW_SATP_ALUA with VMW_PSP_RR and TPGS enabled. After applying the rule, the device shows one active and one standby path. However, the administrator notices that I/O is only sent to the active path. What is the most likely reason?

Accepted Answer

The array is not properly configured to present both paths as active/optimized.. VMW_PSP_RR (Round Robin) with TPGS (Target Port Group Support) enabled only distributes I/O across paths that the array reports as Active/Optimized. If the array presents one path as Active/Optimized and the other as Standby, RR will still send I/O only to the optimized path because ALUA state dictates path usage. The array's target port group configuration must mark both paths as Active/Optimized for RR to load-balance across them.

Answer

The PSP should be changed to VMW_PSP_MRU to use both paths.

Answer

The claim rule should have used VMW_SATP_DEFAULT_AA instead.

Answer

The TPGS option should be disabled to force both paths active.

Question 11

A vSphere administrator is using vSphere Lifecycle Manager (vLCM) to manage an ESXi cluster. The administrator wants to check the compliance status of the cluster against the desired image without making any changes. Which vLCM operation should the administrator perform?

Accepted Answer

Scan. The Scan operation in vLCM evaluates each host's software and firmware against the desired image and produces a compliance status without making changes. Remediation would apply updates, while import and export deal with image management rather than compliance checking. Therefore, scanning is the correct operation to assess compliance safely.

Answer

Export

Answer

Remediate

Answer

Import

Question 12

Which two of the following are characteristics of the vSphere Enhanced vMotion Compatibility (EVC) feature? (Choose two.)

Accepted Answer

It allows vMotion between hosts of different CPU generations within the same cluster. Option B is correct because EVC's core purpose is to enable vMotion (and DRS) between ESXi hosts with different CPU generations by presenting a common, compatible CPU feature set within the same cluster. Option D is correct because EVC achieves this by masking (hiding) newer CPU features from VMs so that all hosts in the cluster expose a uniform baseline CPU feature set, allowing live migration across mixed hardware. Option A is incorrect because EVC is configured at the cluster level (via the cluster's EVC settings), not per individual host. Option C is incorrect because memory overcommit is a separate memory-management behavior controlled by host/VM memory settings and reservations, not a default effect of EVC. Option E is incorrect because EVC can typically be enabled on a cluster without powering off all VMs, provided the hosts are compatible; it does not require all VMs to be powered off.

Answer

It is configured at the host level

Answer

It enables memory overcommit by default

Answer

It requires all VMs to be powered off before enabling

Question 13

A company uses vSphere 7 with vLCM. They want to update hosts in a cluster with a new ESXi version. The cluster has mixed hardware. What is the recommended method?

Accepted Answer

Use cluster image management. For a vSphere 7 cluster with mixed hardware managed by vLCM, the recommended method to update ESXi is cluster image management. vLCM's cluster image is a single desired-state image that includes the ESXi base version plus vendor add-ons and firmware/driver add-ons, and it handles hardware diversity by letting you include the appropriate vendor add-ons for each host model.

Answer

Use vSphere Update Manager baseline

Answer

Manually upload ISO to each host

Answer

Use Auto Deploy

Question 14

A company has a single ESXi host with a standard switch. The administrator creates a new port group for a DMZ network and assigns a VM to it. The VM cannot ping the default gateway. The physical switch port is configured as a trunk with VLAN 100 allowed. The port group VLAN ID is set to 100. The physical NIC is connected to the switch port and shows link up. What should the administrator do to resolve the issue?

Accepted Answer

Verify the VM's IP configuration. The physical switch port is already configured as a trunk allowing VLAN 100, and the port group VLAN ID is correctly set to 100, so the virtual networking layer is properly tagged. The most likely remaining cause is that the VM itself has an incorrect IP address, subnet mask, or default gateway setting for the DMZ subnet. Verifying the guest OS IP configuration is the correct next troubleshooting step.

Answer

Enable VLAN tagging on the physical switch port

Answer

Change the VLAN ID to 0

Answer

Add a second physical NIC to the standard switch

Question 15

A network administrator needs to isolate traffic between VMs in the same VLAN on a distributed switch. Which feature should be used?

Accepted Answer

Private VLAN. Private VLANs (PVLANs) on a vSphere Distributed Switch allow Layer 2 isolation between VMs in the same VLAN by using primary and secondary VLANs with promiscuous, isolated, and community port types. This is the specific feature designed to prevent VM-to-VM traffic within a single VLAN while still allowing communication with a gateway or designated promiscuous ports. It directly addresses the requirement to isolate same-VLAN VM traffic.

Answer

Network I/O Control

Answer

VLAN trunking

Answer

Traffic shaping

Answer

Port binding
