VMware Updated 5V0-21.21 Exam Questions and Answers by riaan

An organization has two vSAN clusters managed by the same vCenter server, each providing 100 TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 40% of its storage capacity.

The company also has the following:

• an iSCSI array of 300 TB, which runs at 76% of its capacity

• a NAS system of 200 TB, which runs at 10% of its capacity

• a Fiber channel (FC) array of 300 TB, which runs at 80% of its capacity

The administrator is asked to add an additional 25 TB of storage to the first cluster but is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.

Which storage option will work for this use case?

During a vSAN design workshop, a customer expressed a requirement to decommission an existing enterprise NAS device that provides iSCSI services for a clustered application.

Based on the current state analysis, the following information was noted:

• Current utilization is 500 LUNs.

• All clustered workloads are configured for Multiple Connections per Session.

• LUN sizes range between 10 TB to 30 TB.

What should the architect state regarding the requirements?

An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.

Which calculation model should be used?

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?
