Alog.retention.hours
Breplication.factor
Cauto.offset.reset
Dmax.poll.records
Step-by-Step Solution
Solution:

  1. Step 1: Identify replication-related Kafka settings

    Replication factor controls how many copies of data Kafka keeps across brokers and datacenters.

  2. Step 2: Match replication.factor to multi-datacenter replication

    Setting replication.factor > 1 ensures data is copied to multiple brokers, enabling multi-datacenter setups.

  3. Final Answer:

    replication.factor -> Option B

  4. Quick Check:

    Replication setting = replication.factor [OK]
Quick Trick: Replication needs replication.factor set > 1 [OK]
Common Mistakes:
  • Choosing unrelated config options
  • Confusing offset or polling settings with replication
  • Ignoring replication factor importance
