NCP Exam - Question 41


A customer has a 24-node cluster with all containers configured with RF3. Two different nodes have incurred a simultaneous HDD failure.

What is the result?

Show Answer
Correct Answer: AD

In a 24-node Nutanix cluster configured with RF3, the system can tolerate up to two simultaneous node or disk failures without immediately losing data. When a disk fails, the cluster continues to operate but in a degraded state. The system will start data replication to maintain the required three replicas once the failed disks are replaced and the cluster is repaired. Hence, the correct outcome is that the cluster runs in a degraded state until the failed drives are replaced and the data has been restored.

A is correct answer

Replication Factor 3 means that you can loose 2x HDDs without affecting VMs/Data. So, answer A is correct.

Why A? For me C seems to be correct as all other answers contain the wording "three replicas" however two disk failed -> two replicas starting to be rebuilt not three.

However I admit that I am wrong as the situation doesn't cause VMs to crash...

Because the RF3 can tolerate two node failures, there must be 3 copies of the Data. Close reading of the answer says it will rebuild "TO" 3 copies of Data.
