Step-by-Step Solution
Solution:
Step 1: Understand requirements for critical system
High load needs many partitions for parallelism; no message loss needs high replication factor.Step 2: Evaluate options
Partitions: 10, Replication factor: 3 has 10 partitions (high load) and replication factor 3 (high safety). Others have fewer partitions or lower replication.Final Answer:
Partitions: 10, Replication factor: 3 -> Option AQuick Check:
High load + safety = many partitions + high replication [OK]
Quick Trick: More partitions + higher replication = speed + safety [OK]
Common Mistakes:
- Choosing low replication for safety
- Choosing few partitions for high load
- Ignoring replication factor importance
