Kafka - Cluster Architecture
Which configuration setting must be specified to run Kafka in KRaft mode?
Abroker.id=1
Bzookeeper.connect=localhost:2181
Clog.dirs=/tmp/kafka-logs
Dprocess.roles=broker,controller
Step-by-Step Solution
Solution:

  1. Step 1: Understand KRaft mode configuration

    KRaft mode requires specifying the roles the node will perform using 'process.roles'.

  2. Step 2: Analyze options

    process.roles=broker,controller correctly sets 'process.roles=broker,controller' enabling KRaft mode. zookeeper.connect=localhost:2181 is for ZooKeeper mode, C and D are general Kafka settings but not specific to KRaft.

  3. Final Answer:

    process.roles=broker,controller -> Option D

  4. Quick Check:

    Use 'process.roles' to enable KRaft mode [OK]
Quick Trick: Set 'process.roles' to enable KRaft mode [OK]
Common Mistakes:
  • Using 'zookeeper.connect' in KRaft mode
  • Omitting 'process.roles' setting
  • Confusing general Kafka settings with KRaft-specific ones
