Step-by-Step Solution
Solution:
Step 1: Calculate replicas per partition
Each partition has 3 replicas because replication factor is 3.Step 2: Multiply by number of partitions
2 partitions x 3 replicas each = 6 total replicas.Final Answer:
6 -> Option AQuick Check:
Partitions x Replication factor = Total replicas [OK]
Quick Trick: Multiply partitions by replication factor [OK]
Common Mistakes:
- Confusing replication factor with total partitions
- Adding instead of multiplying partitions and replicas
- Ignoring replication factor in calculation
