Step-by-Step Solution
Solution:
Step 1: Understand quorum size and fault tolerance
Quorum size is the minimum nodes needed to keep the queue available.Step 2: Calculate minimum quorum for 2 node failures
With 5 nodes, to tolerate 2 failures, quorum size = 5 - 2 = 3.Final Answer:
3 -> Option CQuick Check:
Minimum quorum = total nodes - tolerated failures [OK]
Quick Trick: Quorum size = total nodes minus tolerated failures [OK]
Common Mistakes:
MISTAKES- Setting quorum size equal to total nodes
- Choosing quorum size less than needed for majority
- Confusing quorum size with replication factor
