350-601 Compute Practice Question
A HyperFlex cluster is being designed with 4 nodes using RF2. Which three statements are true about the cluster's data availability and management? (Choose three.)
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
✓
The cluster requires a witness VM for quorum in case of a node failure
With 4-node RF2, the cluster can tolerate one node failure. The witness VM provides quorum. A degraded cluster can still serve data until repaired.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All nodes must be all-flash storage
Why it's wrong here
HyperFlex supports hybrid (HDD+SSD) and all-flash configurations.
- ✓
The cluster requires a witness VM for quorum in case of a node failure
Why this is correct
Correct. The witness provides the tie-breaking vote to maintain cluster quorum.
- ✓
The cluster supports online addition of nodes without downtime
Why this is correct
Correct. HyperFlex allows scaling out by adding nodes without downtime.
- ✓
The cluster can tolerate the failure of one node without data loss
Why this is correct
Correct. RF2 ensures data is on two nodes; one failure is survivable.
- ✗
If two nodes fail simultaneously, all data remains accessible
Why it's wrong here
With RF2, two failures may cause data loss if the same data blocks were on both failed nodes.
