350-601 Compute Practice Question
In a HyperFlex cluster configured with replication factor 2 (RF2), a storage node fails. What is the impact on data availability?
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
✓
Data remains available, but the cluster is degraded and cannot tolerate another node failure until repaired.
With RF2, data is replicated across two nodes. If one node fails, the data remains available on the other node. However, the cluster enters a degraded state until the node is replaced and data is re-replicated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data is lost because only one copy remains.
Why it's wrong here
With RF2, two copies exist; losing one node still leaves one copy intact.
- ✓
Data remains available, but the cluster is degraded and cannot tolerate another node failure until repaired.
Why this is correct
The data is still accessible, but if another node fails, data could be lost since only one copy remains.
- ✗
The cluster stops serving data until the failed node is replaced.
Why it's wrong here
HyperFlex continues to serve data from the remaining replica.
- ✗
The cluster automatically switches to RF3 to maintain redundancy.
Why it's wrong here
RF3 is not automatically enabled; it must be configured at deployment.
