350-601 Compute Practice Question
A company is designing a HyperFlex cluster with 4 nodes and wants to tolerate the failure of any two nodes simultaneously while maintaining data availability. Which replication factor and cluster configuration should be used?
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
✓
RF3 with 4 nodes
HyperFlex HXDP uses replication factor (RF) to determine data copies. RF3 replicates data three times, allowing the cluster to survive up to two concurrent node failures (if the cluster has at least 3 nodes). With 4 nodes, RF3 meets the requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
RF3 with 3 nodes
Why it's wrong here
With 3 nodes, RF3 can survive only one failure (quorum lost with two failures).
- ✓
RF3 with 4 nodes
Why this is correct
RF3 replicates data three times, so the cluster can survive two simultaneous node failures.
- ✗
RF2 with 5 nodes
Why it's wrong here
RF2 still only tolerates one failure even with more nodes.
- ✗
RF2 with 4 nodes
Why it's wrong here
RF2 only allows one failure; two failures would cause data loss.
