Which command deletes a Kafka topic named 'my-first-topic'?

• A. bin/kafka-topics.sh --zookeeper localhost:2181 --topic my-first-topic --describe
• B. bin/kafka-topics.sh --zookeeper localhost:2181 --topic my-first-topic --list
• C. bin/kafka-topics.sh --zookeeper localhost:2181 --topic my-first-topic --delete
• D. bin/kafka-topics.sh --bootstrap-server localhost:9092 --topic my-first-topic --delete

Answer: (C)

Deleting a topic in Kafka is done by using the topic-management script with the delete action, along with the topic name you want to remove. The crucial piece is the --delete flag paired with --topic my-first-topic, which tells Kafka to remove that topic’s metadata and data (assuming broker settings allow it). In the given commands, the one that actually performs deletion includes the delete flag and the topic name and connects to the cluster with --zookeeper, matching the typical usage in this context. The other commands either describe the topic, list topics, or attempt deletion using a different connection method that isn’t shown as the standard approach here. Keep in mind that topic deletion must be enabled on the broker (delete.topic.enable = true) for the delete to succeed.
