2V0-13-25 practice question 3 of 10

An administrator is working on a VMware Cloud Foundation (VCF) Workload Domain that was configured to use vSAN for principal storage. The administrator wishes to create and configure a datastore cluster to host tenant VMs using that vSAN backed storage across multiple clusters, mixed OSA and ESA, in the domain. What should the administrator consider?

Answer options

A: When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore. Correct answer

B: When using vSAN as the underlying datastore, an administrator must create the datastore cluster via vCenter APIs, include the vSAN datastore(s) in it, enable Storage DRS, and ensure the VM Storage Policies reference the appropriate vSAN-capable datastore.

C: A datastore cluster can combine different storage types, such as vSAN, FC, and NFS datastores, as long as they are in the same vCenter; Storage DRS will treat them uniformly.

D: vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.

Correct Answer:

A. When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.

Explanation

VMware vSAN does not support the use of Datastore Clusters or the Storage Distributed Resource Scheduler (Storage DRS) feature. A vSAN datastore is a single, cluster-wide shared datastore that spans all contributing hosts in the vSAN cluster. Because of its unique object-based architecture and its reliance on Storage Policy Based Management (SPBM) for object placement, availability, and load balancing, vSAN handles data distribution natively across the cluster. Consequently, vSAN datastores cannot be added to a Datastore Cluster alongside other storage types. Administrators must manually place virtual machines directly on the vSAN datastore or utilize automated provisioning tools and cloud management platforms that are designed to target the vSAN datastore directly without relying on Storage DRS.

Why Incorrect

Option B: vSAN datastores cannot be included in a datastore cluster via APIs or the UI, and Storage DRS is unsupported.
Option C: Datastore clusters do not support mixing vSAN with other storage types because vSAN is fundamentally incompatible with Datastore Clusters.
Option D: Tagging does not bypass the architectural limitation; vSAN datastores simply cannot participate in Datastore Clusters.
