A cluster has RF2. The cluster loses two drives on different nodes in the same storage tier.
What is the effect on the replicas of the VMs?

In a cluster with RF2 (Replication Factor 2), the system is designed to tolerate the failure of one component (e.g., a drive or node) without data loss. If a second drive fails on a different node before the cluster has had time to rebuild (heal) the lost data, there is a risk of data loss. Therefore, some VM data may be lost in the described scenario.

A is the correct answer
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"
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.
A is correct, there may be some lost of data.
A is correct
If the two disks that failed happen to have pri/ sec copies of VM data then data loss will occur. I vote A.

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 is correct, there may be some lost of data.
I'm still confused what the correct answer would be!
