5V0-21.20 Online Practice Questions and Answers

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?

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

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

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

D. Enable IPv6 networks across all buildings for vSAN connectivity.

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

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

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

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

An administrator observes this health check warning:

Controller firmware is VMware certified

They proceed to update the latest firmware on the Storage Controller. After a successful firmware upgrade, the same health check alert continues to display.

Which statement is true?

A. Controller is not VMware certified and hence any firmware version displays a warning.

B. The recently installed firmware is yet to be certified and included in VMware Compatibility Guide.

C. The VMware vSAN Health Service needs to be restarted for changes to take effect.

D. The alert can be ignored and silenced, since the firmware is newer than the recommended firmware.

An administrator is patching a production Stretched Cluster using VMware Update Manager. Which statement is accurate?

A. The witness hosts can be patched using normal patch processes with VMware Update Manager.

B. Witness hosts cannot be patched or upgraded using VMware Update Manager.

C. The witness host does not need to be upgraded as there is no data on the node, just metadata.

D. The witness host must be deleted and a new witness host must be deployed.

Which should be verified before enabling deduplication and compression?

A. Adequate space is available.

B. Ensure disk groups are balanced.

C. Autoclaim mode is enabled.

D. All hosts are in maintenance mode.

Refer to the exhibit:

The vSAN Health service is reporting 'vSAN Cluster Partition' warning. The partition list shows all hosts from rack 1 in a single partition and all hosts from rack 2 in another partition. Which hardware component requires investigation to resolve the cluster partition?

A. NICs on each host in Rack 2

B. vSAN Master node

C. core switch

D. ToR switches

Which two statements are true about a vSAN Cluster when the vCenter Server managing it is offline? (Choose two.)

A. vSAN health information is available through esxcli commands.

B. vSAN continues to operate and all VMs inherit the default vSAN storage policy.

C. Use a Web browser to monitor vSAN through the vSphere Host Client.

D. Manage and view vSAN health information using RVC commands.

E. vSAN continues to operate, but vSAN performance metrics will be lost.

An administrator is tasked with expanding an existing 2-node vSAN cluster at a remote site to meet the increasing storage capacity requirement by 30%. The existing cache is underutilized. Which solution provides the best configuration that maximizes existing ROI?

A. Scale out two more nodes.

B. Add capacity drives to existing disk groups.

C. Scale out one more node.

D. Replace all cache and capacity with larger drives.

The Cloud Native Storage control plane in vSphere allows an administrator to provision storage directly from which cloud technology?

A. Kubernetes Clusters

B. vRealize Automation

C. Docker nodes

D. AWS EC2 instances

Which Kubernetes component must be configured to allow for dynamics provisioning of container volumes on vSAN?

A. vSphere Container Storage Interface driver

B. vSphere Cloud Storage Plugin

C. glusterfs

D. Cinder
