BothLeaderNotAvailableExceptionandNotEnoughReplicasExceptionare subclasses of RetriableException, which representstransient issuesthat may succeed upon retry.

FromApache Kafka Java Client Documentation:

“RetriableException indicates that the request can be retried. This includes network errors and certain broker-side failures like leader not available or not enough replicas.”

RecordTooLargeException and AuthorizationException arenon-retriablebecause they represent client misconfigurations or access issues.

The ConsumerRebalanceListener lets youhandle partition assignments and revocationsduring rebalances. This is critical for managingoffsets,stateful processing, orexternal transactions.

FromKafka Consumer Rebalance Docs:

“Implementing ConsumerRebalanceListener allows your application to take action before and after partitions are reassigned.”

A is true: It lets your app react when partitionsassigned to the consumer change.

B, C, and D are unrelated to consumer rebalancing directly.

SMTs (Single Message Transforms) arelightweight transformationsapplied to individual messages as they pass through Kafka Connect.

Chaining SMTs: You can applymultiple SMTsin sequence by defining them in order in the connector config.

Masking or modifying fieldsis acommon use case(e.g., redacting sensitive data).

FromKafka Connect Documentation:

“Single Message Transforms (SMTs) are applied to individual messages. You can chain multiple SMTs together.”

SMTsdo not perform joins(B is incorrect).

Converters and SMTs areseparate concerns(D is incorrect).
