VMware App Volumes (VCP-AM 2019) — Question 16

A pre-vSAN 6.6 node is added to a vSAN cluster that was recently upgraded to vSAN 6.7.
What is the expected behavior for this new node?

Answer options

• A. The node will communicate via unicast with all cluster members.
• B. The node will fail to join the vSphere cluster.
• C. The node will communicate via multicast with all cluster members.
• D. The node will be network partitioned from the other cluster members.

Correct answer: B

Explanation

The correct answer is B because a pre-vSAN 6.6 node is incompatible with a vSAN 6.7 cluster and cannot join. Answer A is incorrect as unicast communication is not applicable here, C is incorrect because multicast communication cannot occur either, and D is not accurate as the node simply fails to join rather than being partitioned.
