An administrator has been asked to enable block awareness and increase the fault tolerance to FT2 on a Nutanix AHV cluster with the following configuration:
Four blocks -
One node per block - Will the administrator be able to accomplish these tasks?
A.
No - FT2 requires a minimum of five nodes.
B.
Yes - Block awareness requires a minimum of three blocks.
C.
Yes - FT2 requires a minimum of three nodes.
D.
No - Fault tolerance changes are not supported.
Fault Tolerance Level 2 (FT2), also known as RF3 (Replication Factor 3), requires that data be stored across three fault domains. This means that in the case of a single block failure, data still remains available in the other two fault domains. To achieve FT2, Nutanix requires a minimum of five nodes spread across multiple blocks.
Going back and changing my answer. I was looking at RF2 and not FT2. RF2 needs minimum of 3 blocks, but FT2 needs RF3, which requires 5 nodes in the cluster.
The answer given is correct.
I believe B is the correct answer:

"For replication factor 2, there are a minimum of three blocks in the cluster."

RF and RT are not the same:
