5V0-21.21 Practice Exam Questions with Answers VMware HCI Master Specialist Certification

An architect is designing a vSAN cluster where the hosts have more than 512 GB of memory.

Which two boot devices are recommended for these hosts? (Choose two.)

An administrator wants to deploy Kubernetes on an end-to-end VMware stack, using VMware vSAN for storage.

Which VMware product should the administrator install as the Kubernetes platform choice?

During a maintenance action on a vSAN node, a vSAN administrator noticed that the default repair delay time is about to be reached.

Which two commands must be run to extend the time? (Choose two.)

An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.

Which additional step should the administrator take to ensure no data is lost during the encryption process?

An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.

Which calculation model should be used?

An organization has two vSAN clusters managed by the same vCenter Server, each providing 100TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 50% of its storage capacity.

The company also has the following:

* An iSCSI array of 300TB. which runs at 76% of its capacity

* A NAS system of 200TB, which runs at 10% of its capacity

* A Fiber channel (FC) array of 300TB, which runs at 80% of its capacity

The administrator is asked to add an additional 25TB of storage to the first cluster. The administrator is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.

Which storage option will work for this use case?

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?

A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.

The following requirements must be met:

* Each MSSQL cluster is made up of 3 nodes

* Highest possible availability against node failures

* Some of the vSAN clusters will only consume storage

What should the architect recommend?

An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the “Full-data migration” option.

What will happen after this action is taken?

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.)

An administrator has been tasked with enabling encryption for existing virtual machines on a vSAN cluster.

Which three prerequisites must be satisfied before completing the task? (Choose three.)

An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.

Which storage policy structure rule is supported?

A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.

The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding

* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring

* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring

* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring

During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:

* Preferred Site - Preferred Site workloads should run on DC1 hosts.

* Secondary Site - Secondary Site workloads should run on DC2 hosts.

Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.

To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).

Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)
