5V0-21.20 sample questions

Question 1

Reference the exhibit.

A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of 0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.

What would the architect need change in order to implement a fully supported vSAN Cluster?

Accepted Answer

Add an additional link to the existing adjacent links to make it redundant.

Answer

Enable a single Layer 2 network across all buildings for vSAN connectivity.

Answer

Decrease the existing RTT between the existing links by 0.1ms or more.

Answer

Enable IPv6 networks across all buildings for vSAN connectivity.

Question 2

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 3

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 4

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 5

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 6

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.
