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.
A minimum of 3 nodes is standard for Raft to allow for majority consensus (quorum) if one node fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
1 node.
Why it's wrong here
A single node provides no HA for storage failure.
- ✗
2 nodes.
Why it's wrong here
2 nodes lack sufficient quorum redundancy; if one dies, the cluster stops.
- ✓
3 nodes.
Why this is correct
3 nodes provide a minimum fault-tolerant quorum.
- ✗
10 nodes.
Why it's wrong here
While possible, 10 nodes is overkill for standard HA and introduces performance overhead.
