VCP-DCV Configure and Manage vSphere Storage Practice Test 4 — 15 Questions

Question 1

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

1

Question 2

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 3

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 4

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 5

A vSAN cluster uses a storage policy with Primary Failures to Tolerate (PFTT) = 1 and Failure Tolerance Method = RAID-1 (Mirroring). What is the minimum number of hosts required to support this policy if each host contributes one disk group?

Accepted Answer

3. For RAID-1 mirroring with PFTT=1, vSAN requires at least 3 hosts to provide two copies of data and one witness component. Option B is incorrect because 2 hosts can only support RAID-1 if using stretched cluster or special configuration, but standard requires 3. Option C is incorrect because 4 is more than needed. Option D is incorrect because 6 is too many.

Question 6

An administrator needs to provision an NFS datastore for VMs that require high performance and low latency. The storage array supports multiple NFS versions. Which NFS version should be selected for the best performance?

Accepted Answer

NFS v4.1. NFS version 4.1 provides better performance and security compared to earlier versions, including support for pNFS and sessions. Option B is wrong because NFS v3 is older and has limitations. Option C is wrong because NFS v4.0 lacks some optimizations. Option D is wrong because there is no common NFS v2 in modern environments.

Answer

NFS v2

Answer

NFS v4.0

Answer

NFS v3

Question 7

An administrator needs to expand a VMFS5 datastore that is currently 2 TB in size. The underlying LUN is 5 TB. What is the maximum size the datastore can be expanded to without involving additional LUNs?

Accepted Answer

5 TB. VMFS5 supports datastores up to 64 TB, but the LUN size limits the datastore. The LUN is 5 TB, so the datastore can be expanded to 5 TB (the full LUN size). Option B is incorrect because 2 TB is the current size. Option C is incorrect because 64 TB is the max theoretical size but limited by LUN. Option D is incorrect because 4 TB is not the LUN size.

Answer

64 TB

Answer

4 TB

Answer

2 TB

Question 8

A vSphere administrator is planning a Storage DRS implementation for a datastore cluster containing multiple VMFS datastores. The VMs have various I/O patterns. Some VMs should always remain together on the same datastore. Which configuration should be used?

Accepted Answer

Create a VM-to-VM affinity rule in the datastore cluster.. Storage DRS affinity rules allow you to keep VMs together (VM-to-VM affinity) or separate. Option B is incorrect because anti-affinity would separate them. Option C is incorrect because SIOC is for I/O control, not placement. Option D is incorrect because per-datastore rules don't exist; Storage DRS rules are at the datastore cluster level.

Answer

Set individual datastore affinity rules on each host.

Answer

Apply Storage I/O Control with high shares to the VMs.

Answer

Create a VM-to-VM anti-affinity rule in the datastore cluster.

Question 9

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 10

An administrator is configuring multipathing for a Fibre Channel storage array. The administrator wants to maximize throughput by using all available paths. Which path selection policy should be chosen?

Accepted Answer

Round Robin (VMW_PSP_RR). Round Robin policy distributes I/O across all active paths, maximizing throughput. Option B is incorrect because Fixed uses a single preferred path. Option C is incorrect because Most Recently Used (MRU) uses one path until failure. Option D is incorrect because VMW_PSP_FIXED is essentially Fixed.

Answer

Fixed (VMW_PSP_FIXED)

Answer

Most Recently Used (VMW_PSP_MRU)

Answer

Vendor-specific (VMW_PSP_FIXED_AP)

Question 11

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 12

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 13

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 14

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 15

Refer to the exhibit. What type of virtual disk is represented by this descriptor file?

Accepted Answer

Thick provisioned eager zeroed VMDK. The descriptor shows createType="vmfs" and a single extent with a "flat.vmdk" file. This is a standard thick virtual disk on VMFS, not an RDM. An RDM would have createType="vmfsRaw" or "vmfsRawDeviceMap" and reference a device. Option A is incorrect because it is not an RDM. Option C is incorrect because thin would show createType="vmfsThin". Option D is incorrect because there is only one extent.

Answer

Thin provisioned VMDK

Answer

Sparse disk with multiple extents

Answer

Physical mode RDM
