An administrator created a six node Virtual SAN cluster, created a fault domain, and moved three of the six nodes into that domain.
A node that is a member of the fault domain fails.
What is the expected result?
A.
The remaining two fault domain members are treated as failed.
B.
The remaining two fault domain members stay protected by the domain.
C.
One of the non-member nodes will be automatically added to the fault domain.
D.
VMware High Availability will restart virtual machines on remaining nodes in the domain.
Explanation:
Explanation/Reference:
A is correct.

I guess because of text below from the link, but the article is not very clear on it.
A minimum of three fault domains are required. For best results, configure four or more fault domains in the cluster. A cluster with three fault domains has the same restrictions that a three host cluster has, such as the inability to reprotect data after a failure and the inability to use the Full data migration mode. For information about designing and sizing fault domains, see Designing and Sizing Virtual SAN Fault Domains.

To me it doesn’t make any sense.
The only acceptable answer is D
I think A is correct as well – the remaining members would be treated as failed. A MINIMUM of three fault domains are required. A cluster with three fault domains has the same restrictions that a three host cluster has, such as the INABILITY TO PROTECT DATA AFTER A FAILURE and the inability to use the Full data migration mode.

and Pippers link is a really nice explanation too.
