VMware Certified Master Specialist-HCI 2021 5V0-21.21 Updated Questions

1. 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.)

2. 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.)

3. 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?

4. An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local Protection) configured.

The administrator has been alerted that there is a problem with the cluster.

The following has been observed:

* The vSAN Witness Host is offline.

* Two disk failures on two hosts have occurred in the preferred site.

This has resulted in a critical production virtual machine’s vmdk becoming inaccessible.

Which step needs to be performed by the administrator to resolve the issue?

5. 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.)

6. A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1.

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

* The VMware vCenter Server has recently been upgraded from VMware vSphere 6.7 U3 to version 7.0 U1.

* The vSAN Cluster was recently expanded with identical hardware specification, but from a different hardware vendor.

* The hardware for each vSAN node is listed on the vSAN Compatibility Guide (VCG) for vSAN 7.

* The vSAN Cluster has the following configuration:

- vSAN version: 6.6.1

- Number of vSAN nodes: 10

- Encryption: enabled

- Deduplication and Compression: enabled

- vSAN Capacity Utilization: 60%

* Each vSAN node has the following configuration:

- VMware vSphere ESXi version: 6.5 Update 3

- CPU: 2 processors, 20 cores

- RAM: 768GB RAM.

- Disk: 2 Cache SSDs and 6 Capacity SSDs

- Network: 4 x 10GbE

Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)

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

8. An architect is designing a vSAN cluster.

Which storage controller option will yield optimal performance?

9. 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.)

10. 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?

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

Which VMware product should the administrator install?

12. Which flash disk size is required for the cache tier per ESXi node to meet all requirements?

13. An administrator of “vsan-prod” cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host.

Which action should the administrator take to resolve this issue?

14. 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?

15. 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?
