350-601 Compute Practice Question
In a HyperFlex cluster with replication factor 3 (RF3), a node fails completely. The cluster has five nodes. What is the minimum number of nodes that must be operational for the cluster to continue serving data without interruption?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
3 nodes
With RF3, data is replicated on three nodes. If one node fails, the cluster can continue serving data as long as at least three nodes (including the failed node's replicas on other nodes) are available. Since the cluster has five nodes, even with one failure, four nodes remain, which is sufficient.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
4 nodes
Why it's wrong here
4 nodes are available, but only 3 are needed.
- ✓
3 nodes
Why this is correct
With RF3, as long as at least 3 nodes are operational (the replicas exist on other nodes), data is available.
- ✗
5 nodes
Why it's wrong here
All nodes are not required; the cluster can tolerate a failure.
- ✗
2 nodes
Why it's wrong here
With only 2 nodes, RF3 would have insufficient replicas.
