5V0-21.20 Sample Questions & Answers

An All-Flash vSAN cluster has 4 nodes with this disk group composition on each host:

1 x 800 GB SAS SSD

6 x 3.84 TB SATA SSD

An administrator observes that in an All-Flash cluster, the Write Buffer Free Percentage is consistently low. As a result, there is increased latency experienced by the workloads.

Which remediation steps will resolve this issue?

An administrator receives an alert for vCenter being unavailable. With vCenter running on vSAN, the administrator wants to know if any other VMs are impacted.

What command can an administrator run to determine the overall health of the vSAN objects?

A failed storage controller has two vSAN disk groups attached. The components contained on the drives in those disk groups are marked Degraded. vSAN reports that some objects do not comply with their assigned storage policy.

How is the compliance issue resolved?

During planned maintenance of a four-node vSAN cluster, an outsourced IT contractor accidentally removed a 2.5' SSD cache disk from one of the vSAN nodes. The storage policy has been configured with FTT=1 RAID 1, and the disk management UI marked the disk group as absent.

Which remediation steps should the administrator select to ensure VMs become compliant with the storage policy as soon as possible?

A 3-node All-Flash vSAN cluster has this configuration:

One disk group per host

All disk groups have identical make and model disks of an 800GB NVMe SSD cache and 2x 4TB SAS SSDs each

An administrator has been tasked with expanding storage capacity by adding one additional disk group with this configuration:

1.6TB SAS SSD cache and 1x 4TB SAS SSDs

Assuming all the disks are compliant with the vSAN HCL, which is true?

Which two statements are true about enabling deduplication and compression on an All-Flash vSAN cluster with data? (Choose two.)
