VMware 5V0-21.21 Exam - Topic 2 Question 84 Discussion

Actual exam question for VMware's 5V0-21.21 exam

Question #: 84
Topic #: 2

An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are distributed equally across three racks.

Which action is required to ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure?

AAdd an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (erasure coding).

BAdd two additional hosts per rack, and configure vSAN with three fault domains and FTT=1.

CAdd an additional host per rack, and configure vSAN with three fault domains and FTT=2.

DAdd an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (mirroring).

Show Suggested Answer

Suggested Answer: D

Adding an additional rack with two hosts and configuring vSAN with four fault domains and FTT=1 (mirroring) will ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure. This is because FTT=1 (mirroring) will provide the highest level of redundancy and ensure that if one rack fails, the other racks can still provide the necessary data to remain compliant.

Not sure about D, seems like overkill for just one rack failure.

FTT=2 is a must for rack failure protection.

I feel like adding an additional rack with two hosts might be the right move, but I’m confused about whether to use erasure coding or mirroring for FTT=1.

If I remember correctly, FTT=2 would provide better protection against rack failures, but I’m not clear on how many fault domains we need for that.

I think we practiced a similar question where adding hosts was necessary, but I can't recall if it was about adding hosts per rack or just one additional rack.

I remember that for vSAN, we need to consider fault domains to maintain compliance, but I'm not sure if FTT=1 or FTT=2 is the right choice here.

I'm a bit confused by the question. The options seem to involve adding additional hosts and configuring fault domains, but I'm not sure which one is the correct action to take. I'll need to review the vSAN concepts again.

This looks like a tricky vSAN configuration question. I'll need to carefully consider the details about the cluster and the default vSAN policy.

I'm a bit confused. Why not just add more hosts to each rack instead of a whole new rack? Seems like overkill to me.

Hmm, I'm torn between B and D. But I'm leaning towards D since it specifically mentions mirroring, which seems more robust than erasure coding.
