An employee in the reporting department needs assistance because their data feed is slowing down.

The kafka-consumer-groups.sh script is used to monitor consumer group offsets and lag. It shows the current offset, log end offset, and lag for each partition consumed by a consumer group.

From Kafka documentation:

“You can use kafka-consumer-groups.sh with the --describe flag to get the offset lag per consumer group.”

A → Incorrect: No such built-in script.

B → Correct: Official script for viewing consumer group lag.

C → Incorrect: Does not exist as a built-in Kafka tool.

D → Incorrect: Used for partition reassignment, unrelated to lag monitoring.
