350-601 Compute Practice Question
An engineer is deploying a HyperFlex cluster with three nodes using all-flash storage and replication factor 2 (RF2). What is the minimum number of nodes required to tolerate a single node failure?

Correct answer & explanation
✓
3
With RF2, data is replicated to two nodes. If one node fails, the other node still holds a copy, so the cluster continues. However, for strict fault tolerance, a witness VM is needed to avoid split-brain. Three nodes with RF2 can tolerate one node failure.
