5V0-21.21 VMware HCI Master Specialist Questions and Answers

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?

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

What should the administrator configure?

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.)

An architect is designing a vSAN cluster.

Which storage controller option will yield optimal performance?

During a design workshop for a stretched vSAN cluster, the requirement that some of the VMs be configured with no-mirror between sites was discussed.

Which three recommendations should the architect provide to address an event of a network partition between two sites? (Choose three.)

A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1. The company wants to ensure that the same vSAN process can be used in the future.

During the discovery phase, the consultant found the following information about the existing environment:

* The vCenter Server is currently version 7.0.

* The vSAN Cluster has the following configuration:

- vSAN version: 7.0

- Number of vSAN nodes: 6

- Encryption: enabled

- Deduplication and Compression: enabled

- Fault Domains: 1

- vSAN Capacity Utilization: 60%

* Each vSAN node has the following configuration:

- ESXi version: VMware vSphere 7.0

- CPU: 2 processors, 20 cores

- RAM: 1024GB RAM.

- Disk: 2 Cache SSDs and 6 Capacity SSDs

- Network: 4 x 10GbE

* All current hardware (which is from a single vendor) is listed on the vSAN Compatibility Guide for vSAN 7.

Which three recommendations should the consultant make to ensure that the vSAN cluster upgrade is completed? (Choose three.)

After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).

Which step should be taken to resolve this issue?

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 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 is tasked with setting up Kerberos authentication only for the vSAN File services.

Which version of Kerberos must be selected if the NFS version is v4.1?

An administrator is planning to change a vSAN Storage Policy to apply a Failures To Tolerate (FTT) of 2, using RAID-6.

What is the minimum number of vSAN nodes required?

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.)

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?

An architect is currently working with a customer to transform their existing ESXi hosts to vSAN nodes. The customer expressed the following requirements.

• First phase will transform 50% of the hosts to a hybrid vSAN nodes.

• Second phase will transform the remaining 50% hosts to an All-Flash vSAN nodes.

The following constraint exists:

• Each host has a 4-port x 1 GbE network interface.

Which two recommendations should the architect make to align with the customer's requirements? (Choose two.)

An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster where the virtual machines migration will be orchestrated via VMware Site Recovery Manager.

Which action should the administrator take so the migration is successful?
