Which command would you use to list all topics without describing them?

• A. bin/kafka-topics.sh --zookeeper localhost:2181 --describe --list
• B. bin/kafka-topics.sh --zookeeper localhost:2181 --topic my-topic --list
• C. bin/kafka-topics.sh --zookeeper localhost:2181 --delete
• D. bin/kafka-topics.sh --zookeeper localhost:2181 --list

Answer: (D)

To see every topic in the cluster, you want a simple list of names. Use the Kafka topics script with the --list flag, connecting to Zookeeper as shown. This command outputs just the topic names without any extra details. The other options would either display details for topics (--describe), limit the output to a specific topic (--topic with a name), or delete topics (--delete), which is not what you want when listing all topics. Note that in newer Kafka versions you’d use --bootstrap-server instead of --zookeeper, but the given syntax uses --zookeeper.
