5V0-21.21 Sample Questions Answers

A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.

The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding

* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring

* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring

* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring

During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:

* Preferred Site - Preferred Site workloads should run on DC1 hosts.

* Secondary Site - Secondary Site workloads should run on DC2 hosts.

Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

A vSAN policy has been configured with Erasure Coding on a vSAN stretched cluster.

Which RAID level and FTT setting have been specified?

An administrator is tasked to create a custom storage policy for workloads and is including additional disk stripes while defining the storage policy.

What is the main purpose of this practice?

An architect is designing a vSAN cluster.

Which storage controller option will yield optimal performance?

An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.

Which requirement is specifically needed for these devices?

An architect collected the below technical requirements from the customer during a vSAN cluster design workshop:

* Maximize the vSAN datastore usable capacity.

* Deduplication and compression are required to help utilize available capacity efficiency.

* Ensure the highest level of resiliency wherever possible.

Which disk group configuration should the architect include in the design?

An administrator has been tasked to reboot a node in an encrypted vSAN cluster. The vSAN disk groups on that node become locked after rebooting the node.

Which step should be performed to exit the locked state?

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.)

As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.

The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.

What could be the cause of this performance degradation issue?

A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish.

During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied.

What will be the status of the vSAN objects on the affected host immediately after it is recovered?

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?

Upon checking the latency goal under vSAN performance diagnostics, the vSAN Administrator sees this message displayed:

The increase in latency in the vSAN stack might be beyond expected limits.

Which two root causes can be identified to help remediate the issue? (Choose two.)

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?

Due to an update in their security requirements, an organization is no longer compliant because the metadata traffic between hosts in their vSAN cluster is not being encrypted.

Which step must be taken by the administrator to meet the new security requirements?

An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.

Which storage policy structure rule is supported?

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