VMware 5V0-21.21 Exam Questions Instant Access

Question 1

An administrator wants to deploy a desktop and application virtualization solution on top of vSAN.

Which VMware product should the administrator install?

AVMware Dynamic Environment Manager

BVMware Horizon Apps

CVMware Workspace One Access

DVMware Horizon

Answer : D

Question 2

During a vSAN design workshop, a customer expressed a requirement to decommission an existing enterprise NAS device that provides iSCSI services for a clustered application.

Based on the current state analysis, the following information was noted:

* Current utilization is 500 LUNs.

* All clustered workloads are configured for Multiple Connections per Session.

* LUN sizes range between 10 TB to 30 TB.

What should the architect state regarding the requirements?

AAll requirements can be satisfied without any change.

BOnly single connection per session is supported.

CThe number of LUNs require additional licensing.

DIt is a best practice to maintain a LUN size of 8 TB.

Question 3

An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the dat

a. Both vSAN clusters are managed by the same vCenter server.

What should the administrator configure?

ANFS volumes on vSAN

BiSCSI targets on vSAN

CHCI Mesh on vSAN

DvVOLs on vSAN

Answer : C

The administrator should configure HCI Mesh on vSAN in order to share storage from one vSAN cluster to another vSAN cluster while preserving SPBM management end-to-end and applying the policy by the source vSAN cluster. According to the VMware documentation, 'HCI Mesh enables vSAN clusters to share storage capacity with each other. You can create a stretched cluster with a maximum of four sites, or you can create a stretched cluster with multiple sites, with a maximum of 32 sites in a single vSAN domain. HCI Mesh supports the vSAN Stretched Cluster features, including Distributed RAID, Erasure Coding, and SPBM policy enforcement.'

Question 4

During a vSAN design workshop, an architect collected these customer requirements:

* Leverage vSAN storage policies with Erasure Coding.

* Enable Deduplication and Compression.

* Use the minimum number of hosts in the cluster.

* Maintain full storage policy compliance when two nodes are down.

Which vSAN cluster design meets the customer's requirements?

AFive nodes All-Flash vSAN cluster

BSix nodes All-Flash vSAN cluster

CSix nodes Hybrid vSAN cluster

DFive nodes Hybrid vSAN cluster

Answer : B

Question 5

As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.

The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.

What could be the cause of this performance degradation issue?

AMTU 9K is not configured on the hosts vSAN vMKernel ports.

BMTU 9K is not configured on the hosts VMnic ports.

CMTU 9K is not configured on the ToR switch.

DMTU 9K is not configured on the vDS switch.

Answer : C

Question 6

An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services.

The following information is known about the vSAN Cluster:

* vSAN 7.x Cluster

* vSAN node count: 8

* De-Duplication and Compression: Enabled.

* Encryption: Disabled

* Current Utilization: 45%

* Disk Groups: 2

* Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD

Which three steps should the administrator take to successfully complete the task? (Choose three.)

ARemove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.

BReplace the failed disk with a storage device that is identical in class and capacity.

CRemove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.

DReplace the failed disk with a storage device that is identical in class but smaller in capacity.

EPut the affected vSAN host into maintenance mode to physically replace the storage device.

FRemove the affected Disk from the Disk Group, and choose Full Data Migration.

Answer : B, E, F

If you upgrade the capacity device, verify the following requirements:

- Verify that the cluster contains enough space to migrate the data from the capacity device.

- Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode.

'Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group.'

Question 7

Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.

Which two causes explain this behavior? (Choose two.)

AThe cluster DRS threshold has been set to Aggressive.

BThere is a vSAN node failure.

CThe vSAN Resync throttling is enabled.

DThe object repair timer value has been increased.

EThe vSAN policy protection level has changed from FTT=0 to FTT=1.

Answer : B, E
