VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 21

An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?

Answer options

• A. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.
• B. Run both resource profiles on the same cluster with the same host hardware platform.
• C. Separate the two resource profiles into two clusters. The Tier 2 cluster will have faster CPU and more memory while the Tier 1 cluster will have slower CPU and less memory but more disk space.
• D. Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.

Correct answer: A

Explanation

The correct answer is A because it allows the Tier 1 virtual machines, which need high disk performance, to be placed on a cluster with fast storage, optimizing their performance. Option B does not account for the differing I/O requirements, which could lead to performance degradation. Option C incorrectly assigns better CPU and memory to Tier 2, which does not require it, while Option D over-provisions resources for both profiles, which is inefficient and unnecessary.
