VMware Cloud Foundation 3.x Administrator — Question 28

A vSphere Administrator is tasked with implementing a production VMware vSAN cluster and has followed the design and sizing guide to correctly size the environment.
Which two requirements represent valid VMware recommendations? (Choose two.)

Answer options

• A. A disk group must be composed of more than one cache disk and at least one capacity disk.
• B. All-Flash configurations do not require a caching tier.
• C. A disk group must be composed of one cache disc and at least one capacity disk.
• D. The cache tier should be sized to no less than 10% of the capacity tier.

Correct answer: C, D

Explanation

Option C is correct because a disk group in a VMware vSAN must have one cache disk and at least one capacity disk, which ensures proper data handling. Option D is also accurate as the cache tier should not be less than 10% of the capacity tier to maintain optimal performance. Options A and B are incorrect; A misrepresents the required composition of cache and capacity disks, while B incorrectly states that All-Flash configurations do not need a caching tier.
