Question 1

When designing a vSAN Cluster, which three should be considered when sizing a vSAN datastore? (Choose three.)

Accepted Answer

Storage Policy or Policies to be used

Accepted Answer

capacity device queue depth

Accepted Answer

vSAN Slack Space

Answer

cache disks with 10% of the Disk Group

Answer

On-Disk Format overheard

Answer

endurance level of capacity disk used

Question 2

Which must be configured by a Kubernetes user allow for dynamic provisioning of container volumes in vSAN using storage policies?

Accepted Answer

StorageClass

Answer

ReplicaSet

Answer

Pod

Answer

ReplicationController

Question 3

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?

Accepted Answer

Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.

Answer

Add a second disk group with a new cache device and distribute the capacity disks equally.

Answer

Add a second cache device to the same disk group to increase the caching size.

Answer

Replace the existing cache device with a larger cache device.

Question 4

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?

Accepted Answer

esxcli vsan cluster get

Answer

esxcli vsan storage list

Answer

esxcli vsan cmmds timemachine get

Answer

esxcli vsan health cluster list

Question 5

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?

Accepted Answer

Rebuilding of the degraded components starts immediately.

Answer

Initiate a proactive rebalance to force component repairs.

Answer

Degraded components are repaired after CLOM Repair Delay Timer expires.

Answer

Storage policies must be reapplied to all affected objects.

Question 6

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?

Accepted Answer

replace the SSD cache disk > rescan > add disk back in disk group

Answer

enter host in maintenance > remove from disk group > shutdown host > replace disk > power on host

Answer

remove disk group > enter host in maintenance > fully evacuate all data > exit maintenance

Answer

vSAN Health Check > retest > object health > repair objects immediately
