Step-by-Step Solution
Solution:
Step 1: Calculate replicas per partition
Each partition has replication factor 2, so 2 replicas per partition.Step 2: Multiply by number of partitions
2 partitions x 2 replicas each = 4 total replicas.Final Answer:
4 -> Option CQuick Check:
Total replicas = partitions x replication factor = 4 [OK]
Quick Trick: Total replicas = partitions x replication factor [OK]
Common Mistakes:
- Confusing brokers with replicas
- Multiplying brokers by replication factor
- Ignoring number of partitions
