Selected Answer: A
If the two disks that failed happen to have pri/ sec copies of VM data then data loss will occur. I vote A.

For RF-2, we have FT-1, meaning it can sustain a single simultaneous failure. In that case. one disk or node can fail and there will be no impact to VM data or cluster operation. But, for 2 simultaneous failure it will loose some VM data. Hence, A should be correct.

In a cluster with RF2 losing a second drive in a different domain (node, block, or fack) before the cluster heals can result in some VM data loss to both replicas. So the e correct option is A.

A = Some VM data "may" be lost. "A" matched courseware info on RF2 where it states losing a second drive in another node before the node heals "can result in some VM data loss"

Your example is pointing to a post, however the courseware says but if you remember the training, it says in RF2, losing a second drive in another node before the cluster heals "can result in some VM data loss"
