5V0-21.21 VMware HCI Master Specialist Questions and Answers

An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.

Why is this behavior being seen?

A 4-node vSAN cluster is configured with an erasure coding storage policy. The Ensure Accessibility maintenance mode was selected. While performing the maintenance, a second node fails.

What will be the impact on the vSAN cluster?

An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are distributed equally across three racks.

Which action is required to ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure?

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?

Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.

The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.

The current vSAN cluster has the following configuration:

* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

* 1 Disk Group per vSAN node

- 1 x 400 GB

- 4 x 1.8 TB

* De-duplication and Compression is enabled.

* vSAN Capacity is currently:

- Total: 72 TB

- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.

Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

* Highest possible mitigation during a host failure in terms of capacity.

* A constraint in this year’s IT budget.

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 architect collected the below technical requirements from the customer during a vSAN cluster design workshop:

* Maximize the vSAN datastore usable capacity.

* Deduplication and compression are required to help utilize available capacity efficiency.

* Ensure the highest level of resiliency wherever possible.

Which disk group configuration should the architect include in the design?

A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.

Which action should the vSAN administrator take to reduce the negative impact on the VMs?

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 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 administrator notes that the Data-At-Rest Encryption keys have expired.

Which action is needed to resolve this situation?

Upon checking the latency goal under vSAN performance diagnostics, the vSAN Administrator sees this message displayed:

The increase in latency in the vSAN stack might be beyond expected limits.

Which two root causes can be identified to help remediate the issue? (Choose two.)

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.)

A customer has upgraded to vSAN 7, but there is still an existing legacy host which must be removed from the vSAN cluster.

Which three steps must an administrator take to successfully remove this host from the vSAN cluster? (Choose three.)
