Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 14

What is a consideration when planning for node expansion of an existing 4-node All-Flash Dell EMC VxRail 4.5.2xx cluster?

Answer options

• A. vSphere Web Client is used to perform the expansion procedure
• B. New nodes can be hybrid or All-Flash
• C. New nodes must be identical to the existing nodes
• D. Expansion procedure is performed by Dell EMC or a Dell EMC partner

Correct answer: C

Explanation

The correct answer is C, as all nodes in a VxRail cluster must be identical to ensure compatibility and optimal performance. Option A is incorrect because while the vSphere Web Client plays a role, it is not the only consideration. Option B is wrong since new nodes need to be the same type (All-Flash) as existing ones. Option D is not accurate in all cases, as expansions can sometimes be performed by qualified internal staff.
