To build a fault-tolerant Kafka system, which combination is best practice?
AProducer retries disabled
BMultiple brokers with replication factor > 1
CMultiple consumer groups with one partition
DSingle broker with multiple partitions
Step-by-Step Solution
Solution:

  1. Step 1: Understand fault tolerance in Kafka

    Replication across multiple brokers ensures data is safe if one broker fails.

  2. Step 2: Evaluate options

    Single broker or single partition lacks redundancy; disabling retries reduces reliability.

  3. Final Answer:

    Multiple brokers with replication factor > 1 -> Option B

  4. Quick Check:

    Replication and multiple brokers = fault tolerance [OK]
Quick Trick: Use replication and multiple brokers for fault tolerance [OK]
Common Mistakes:
  • Relying on single broker for fault tolerance
  • Ignoring replication factor
  • Disabling producer retries reduces reliability
