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

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.)

An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.

Which requirement is specifically needed for these devices?

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 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?

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 architect is designing for a production vSAN cluster, and the customer introduced these requirements related to File Services: A minimum of 12 files shares. 30TB NFS capacity to mount workload VMs.

What should be the architect’s recommendations?

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

Which action is needed to resolve this situation?

An architect is tasked to design a VMware Horizon Solution with vSAN. The architect needs to use a solution to host the user’s profile shares in a highly available manner, and it must be guest OS independent.

Which solution will match these requirements?

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.)

Due to an update in their security requirements, an organization is no longer compliant because the metadata traffic between hosts in their vSAN cluster is not being encrypted.

Which step must be taken by the administrator to meet the new security requirements?

An administrator is tasked with migrating a VMware Horizon View environment that is currently running on an NFS Datastore to VMware vSAN.

Which Horizon configuration option will not be available when configuring vSAN in Horizon View?

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 architect is working with vSAN and setting the fault domains to support FTT=1.

How many fault domains will be needed?

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

* A constraint in this year’s IT budget.

What should the architect recommend?
