Question 2

Your organization has a mission-critical Kafka cluster that must be highly available. A Disaster Recovery (DR) cluster has been set up using Replicator, and data is continuously being replicated from source cluster to the DR cluster. However, you notice that the message on offset 1002 on source cluster does not seem to match with offset 1002 on the destination DR cluster.
Which statement is correct?

A. The offsets for the messages on the source, destination cluster may not match.

B. The message was updated on source cluster, but the update did not flow into destination DR cluster and errored.

C. The message on DR cluster got over-written accidently by another application.

D. The DR cluster is lagging behind updates; once the DR cluster catches up, the messages will match.

B. The Consumer offset is greater than the last offset in the partition (log end offset).

C. The Consumer Group started for the first time.

D. The Consumer offset is less than the smallest offset in the partition (log start offset).
