VCP-DCV Practice Test 34 — 15 Questions

Question 1

Refer to the exhibit. What does this error indicate?

Accepted Answer

The target LUN is not available.. SCSI sense key D:0x2 indicates 'Not Ready', meaning the LUN is not available. Host bus adapter failure or path misconfiguration would produce different sense codes; no path would show a different state.

Answer

The path is misconfigured.

Answer

The storage device is not connected.

Answer

The host's HBA is faulty.

Question 2

Which TWO vSAN components are always created for every virtual disk object in a vSAN datastore? (Choose two.)

Accepted Answer

Metadata component

Answer

RAID-5 parity component

Answer

Checksum component

Answer

Witness

Question 3

Refer to the exhibit. An administrator runs the 'esxcli storage core device list' command and sees the output. The storage array is an active-passive array with ALUA. The current path selection policy is set to Fixed with no preferred path. What is the consequence of this configuration?

Accepted Answer

I/O may be sent to a non-optimized path, causing higher latency. With an active-passive ALUA array, using Fixed policy with no preferred path means the host may not automatically switch to the active path, causing I/O to potentially go through the passive path (if it is accessible but not optimized). Option B is correct. Option A is wrong because only one path is active at a time. Option C is wrong because ALUA is supported. Option D is wrong because RDM is irrelevant.

Answer

The I/O is load-balanced across all four paths

Answer

ALUA is not supported, so the host will use only one path

Answer

The device cannot be used for VMDKs, only for RDM

Question 4

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 moves VM disks between datastores while preserving the storage policy association. vMotion moves compute only; cold migration requires downtime; clone creates a copy.

Answer

Cold migration

Answer

Clone

Answer

vMotion

Question 5

An administrator attempts to expand a VMFS datastore by increasing the LUN size, but the expand option is grayed out. What could be the reason?

Accepted Answer

The LUN is shared with another datastore. If the LUN is shared with another datastore, it cannot be expanded because a LUN can belong to only one datastore. Block size does not affect expansion; RDMs are not used for VMFS; rescan is unrelated to the grayed-out option.

Answer

The datastore is using block size 2 MB

Answer

The host is not rescanned

Answer

The datastore is on a RDM

Question 6

Refer to the exhibit. A VM is deployed with this storage policy. What is the minimum number of hosts required for the VM's objects to be provisioned successfully?

Accepted Answer

3. With FTT=1 and default RAID-1 mirroring, vSAN needs 2 data replicas plus 1 witness, requiring at least 3 hosts. A single host cannot tolerate failure; two hosts would work for FTT=0.

Answer

Question 7

A company experiences high latency on a VM running a critical database. The storage is a VMFS datastore on a SAN. The administrator notices that other VMs on the same datastore are idle. What should the administrator configure to ensure the database VM gets sufficient storage I/O resources?

Accepted Answer

Configure Storage I/O Control and set the database VM's shares to High.. Storage I/O Control (SIOC) enables dynamic sharing of storage I/O resources among VMs on a datastore. By setting a higher share value for the database VM, it will get priority when congestion occurs. Option B is wrong because shares do not set a limit; they are relative weighting. Option C is wrong because limiting all other VMs would be inefficient and may cause starvation. Option D is wrong because DRS is for compute load balancing, not storage I/O.

Answer

Set storage I/O limits on all other VMs to 100 IOPS.

Answer

Configure Storage I/O Control and set a latency threshold of 5 ms.

Answer

Use Storage DRS to migrate idle VMs to another datastore.

Question 8

A vSphere administrator configures a VVol datastore on a Pure Storage array. The administrator creates a storage policy with a custom tag. After attaching the policy to a VM, the VM remains uncompliant. What is the most likely cause?

Accepted Answer

The storage array does not support the capability specified in the policy.. VVol storage policies rely on capabilities advertised by the array via VASA. If the array does not advertise the tag used in the policy, VMs remain uncompliant. Option A is incorrect because protocols like NFS or iSCSI do not affect VVol compliance. Option B is incorrect because VVols do not use VMFS. Option D is incorrect because storage DRS is irrelevant for a single VM.

Answer

The storage array is not VASA-compliant.

Answer

The datastore cluster is not configured for Storage DRS.

Answer

The VVol datastore is using NFS protocol instead of iSCSI.

Question 9

Which THREE conditions must be met for Storage I/O Control (SIOC) to work effectively? (Choose three.)

Accepted Answer

The datastore must be VMFS5 or later.

Answer

Jumbo frames must be enabled on the storage network.

Answer

The datastore must be connected via Fibre Channel only.

Question 10

Which THREE of the following are characteristics of vSAN stretched clusters?

Accepted Answer

Provides site-level fault tolerance. Stretched clusters require a witness host in a third location, provide site-level fault tolerance, and require two fault domains (one per site). RAID 5/6 is supported but not unique to stretched clusters; it is still a single vSAN cluster.

Answer

Supports RAID 5/6 erasure coding

Answer

Uses a dedicated vSAN cluster separate from the main datastores

Question 11

An administrator needs to attach a SAN LUN to a VM for a clustered application that requires SCSI-3 persistent reservations. The VM will run on two hosts in a cluster. Which storage option should be used?

Accepted Answer

Create a physical mode RDM (Raw Device Mapping).. Physical RDM (Raw Device Mapping) supports SCSI-3 persistent reservations and allows sharing the LUN between VMs in a cluster. Virtual compatibility mode (virtual RDM) does not support persistent reservations. Option A is incorrect because VMDK on VMFS does not support persistent reservations. Option B is incorrect because virtual RDM does not support it.

Answer

Create a virtual mode RDM (Raw Device Mapping).

Answer

Create a thick-provisioned eager zeroed VMDK on VMFS.

Answer

Create a VVol representing the LUN.

Question 12

An administrator needs to create a datastore cluster for a set of VMs that require high availability. The VMs should be automatically balanced across datastores based on I/O latency. Which feature must be enabled on the datastore cluster?

Accepted Answer

Storage DRS with I/O metric enabled.. Storage DRS with I/O metric enabled allows automatic balancing based on I/O latency. Option A is incorrect because SIOC is per-datastore, not for the cluster. Option C is incorrect because vSphere HA is for host failures, not storage balancing. Option D is incorrect because Storage DRS can be enabled without SIOC, but I/O balancing requires the I/O metric.

Answer

Storage I/O Control (SIOC) on each datastore.

Answer

vSphere HA for the datastore cluster.

Answer

Storage DRS without I/O metric, using space only.

Question 13

Which TWO statements are true about datastore heartbeating in vSphere HA? (Choose two.)

Accepted Answer

At least two datastores should be selected for heartbeating to provide redundancy.

Answer

Datastore heartbeating is enabled by default when vSphere HA is configured.

Answer

Datastore heartbeating is used to detect host isolation.

Answer

vSphere HA uses datastore heartbeating as the primary method for failure detection.

Question 14

A company has a vSphere cluster consisting of 8 ESXi hosts connected to a single Fibre Channel SAN array. They use VMFS6 datastores to store virtual machine files. The storage administrator has scheduled a firmware upgrade for the SAN array that requires a controller reboot. This will cause a temporary loss of connectivity to one LUN (datastore) for approximately 5 minutes. The datastore hosts 15 production VMs, including critical database servers. The cluster has sufficient spare capacity on other datastores, but the VMs are large (each about 200 GB). The vSphere administrator must ensure that these VMs remain available during the upgrade. The cluster has vSphere HA enabled with default settings. What should the administrator do to meet the requirement?

Accepted Answer

Use Storage vMotion to migrate all VMs on the affected datastores to a healthy datastore before the upgrade.. Using Storage vMotion to live-migrate VMs to a healthy datastore (B) ensures zero downtime during the upgrade. Option A puts hosts into maintenance mode, disrupting VMs. Option C does not protect against storage loss. Option D is for host failure scenarios, not storage disruption.

Answer

Configure a vSphere HA admission control policy to reserve resources in case of host failure.

Answer

Place all ESXi hosts into maintenance mode.

Answer

Enable Storage I/O Control on the affected datastore to manage I/O during the upgrade.

Question 15

A company deploys a VDS with multiple uplinks and uses Route based on originating virtual port for load balancing. The network team reports that traffic from VMs on the same host is not balanced across uplinks. The administrator verifies that the physical switch ports are all in the same port-channel. What could be the cause?

Accepted Answer

The uplinks are configured in active/standby mode. Option D is correct because if the uplinks are configured as active/standby, only one uplink is active at a time, so no load balancing occurs regardless of the algorithm. Option A (algorithm not supported) is irrelevant as this is a vSphere algorithm. Option B (few VMs) might reduce distribution but not eliminate it entirely. Option C (explicit failover order) still allows multiple active uplinks if configured with multiple active paths.

Answer

The load balancing algorithm is not supported by the physical switch

Answer

The number of VMs is less than the number of uplinks

Answer

The teaming policy uses an explicit failover order
