VMware vSphere 8.x Advanced Design (VCAP-DCV Design) — Question 36

An architect is designing a new vSphere solution. The customer has provided the following information to describe how the solution will be used:
The solution will host development workloads
Administrators will utilize snapshots frequently, with snapshots sometimes retained for extended periods of time
Some of the workloads are sensitive to latency on the I/O of the storage
Storage for the workloads will be provided by a physical array
The physical array does not include a storage provider
All workloads must be hosted on the solution, there are no other vSphere environments available for use
Which design decision should the architect make to meet the needs of the customer?

Answer options

• A. Use a storage array which supports VMware vSphere APIs: Array Integration (VAAI) to configure VMFS datastores for the workloads
• B. On workloads which will use snapshots, set the latency-sensitivity=high advanced setting
• C. Use a storage array which supports vSphere Storage APIs - Storage Awareness (VASA) to configure Virtual Volumes (vVols) datastores for the workloads
• D. On workloads which are sensitive to latency, set the latency-sensitivity=high advanced setting

Correct answer: A

Explanation

The correct answer, A, is appropriate because using a storage array that supports VAAI enhances performance and efficiency for VMFS datastores, which is essential given the frequent use of snapshots. Options B and D focus on adjusting settings for latency sensitivity but do not address the underlying storage performance needs, while option C suggests using vVols, which is not suitable given the absence of a storage provider.
