VCP-DCV Configure and Manage vSphere Storage Practice Test 3 — 15 Questions

Question 1

Refer to the exhibit. An administrator checks the vSAN cluster health and sees the above output. The cluster has been running for months. What is the most likely cause of the degraded objects?

Accepted Answer

A disk failure occurred and components are being rebuilt. Degraded objects in vSAN indicate that component failures have occurred and repair is ongoing (resyncing). Option C is correct. Option A (network) would show connectivity issues. Option B (capacity) would show rebalance. Option D (policy change) would cause reconfiguration but not typically degrade.

Answer

A storage policy was changed to increase redundancy

Answer

A disk group is full and needs capacity expansion

Answer

A network partition between hosts

Question 2

Refer to the exhibit. An administrator runs the 'vmkfstools -P -v 10' command on a datastore. What is the total capacity of the datastore?

Accepted Answer

3 TB. The datastore has two extents: one with 1,048,576 blocks and one with 2,097,152 blocks, both with 1 MB block size. Total blocks = 3,145,728. Since each block is 1 MB, total capacity is 3,145,728 MB, which is approximately 3.14 TB. Option D is correct. Option A (1 TB) is the size of the smaller extent. Option B (2 TB) is the larger. Option C (2.5 TB) is incorrect.

Answer

2.5 TB

Answer

2 TB

Answer

1 TB

Question 3

What is the maximum number of paths that vSphere supports for a single storage device?

Accepted Answer

32. vSphere supports up to 32 paths per storage device. 4 paths is common for some arrays, 8 is typical but not the maximum, and 256 is too high.

Answer

8

Answer

256

Answer

4

Question 4

An administrator notices that a VM with high I/O demands is experiencing performance issues because other VMs on the same datastore are consuming too many I/O operations. Which feature can be used to guarantee a minimum I/O share to this VM?

Accepted Answer

Storage I/O Control shares. Storage I/O Control (SIOC) allows setting shares, limits, and reservations to allocate I/O bandwidth per VM. Storage DRS balances I/O across datastores, not per-VM; multipathing selects paths; VM storage policies manage provisioning.

Answer

Multipathing policy

Answer

VM storage policy

Answer

Storage DRS

Question 5

What is the default block size of a VMFS5 datastore?

Accepted Answer

1 MB. VMFS5 uses a default block size of 1 MB. Larger block sizes are available but not default.

Answer

8 MB

Answer

2 MB

Answer

4 MB

Question 6

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 7

A vSphere cluster has multiple storage arrays with different capabilities. The administrator wants to automatically place VMs on datastores that match their storage policy. What is required?

Accepted Answer

VM storage policy and Storage DRS. Storage DRS uses VM storage policies to automatically place VMs on datastores that satisfy the policy requirements. SIOC is for I/O control; VASA provides capabilities but does not automate placement without Storage DRS.

Answer

VASA provider

Answer

Storage DRS only

Answer

Storage I/O Control

Question 8

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 9

An administrator wants to use Storage DRS to balance space usage across datastores. What must be configured?

Accepted Answer

Storage DRS automation level. The storage DRS automation level (manual, partially automated, fully automated) controls whether migration recommendations are generated or applied automatically. SIOC, policies, and host affinity are not required for space balancing.

Answer

Host affinity rules

Answer

SIOC

Answer

Storage policy

Question 10

A vSAN cluster has two fault domains. What is the maximum number of host failures that can be tolerated if the cluster is configured with a storage policy that sets 'Number of failures to tolerate' to 2?

Accepted Answer

2. With FTT=2, the VM can survive up to 2 host failures regardless of fault domains. Fault domains ensure that failures are isolated, but the FTT value directly sets the tolerance.

Answer

1

Answer

3

Answer

4

Question 11

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

Accepted Answer

vSAN. vSAN pools local disks from multiple hosts into a shared datastore. VMFS is a filesystem, NFS is network storage, vFlash is caching.

Answer

VMFS

Answer

vFlash

Answer

NFS

Question 12

Which TWO of the following are required for vSphere Storage DRS to function?

Accepted Answer

vMotion enabled on the hosts. Storage DRS requires multiple datastores in a datastore cluster and vMotion to migrate VMs between them. SIOC, VASA, and storage policies are optional.

Answer

VM storage policies defined

Answer

VASA provider registered

Answer

SIOC enabled on each datastore

Question 13

Which TWO of the following are prerequisites for enabling jumbo frames on a vSphere host for storage traffic?

Accepted Answer

The VMkernel port must be configured with MTU 9000. Jumbo frames require physical switch support and VMkernel port MTU configuration. The storage array, guest OS, and vCenter do not directly affect host-level jumbo frame operation.

Answer

The virtual machine guest OS must support jumbo frames

Answer

The storage array must support jumbo frames

Answer

The vCenter Server must be configured for jumbo frames

Question 14

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 15

Refer to the exhibit. What is the most likely reason the second path is in standby state?

Accepted Answer

The storage array reports that path as non-optimized.. The SATP is ALUA, which uses asymmetric states. 'Standby' indicates a non-optimized path. Zoning issues or authentication errors would result in a dead path, not standby. The PSP is round-robin, so it is not Fixed.

Answer

The host has not successfully authenticated to the storage on that path.

Answer

The path is not properly zoned to the storage.

Answer

The multipathing policy is set to Fixed (VMW_PSP_FIXED).
