CCDAK Exam Dumps : Confluent Certified Developer for Apache Kafka Certification Examination

Kafka Connectsource connectorsuse theoffset.storage.topicconfiguration parameter to define where to storeoffsets that track the connector's positionin the source system (e.g., database, file, etc.).

FromKafka Connect Worker Configuration:

“offset.storage.topic specifies the topic in Kafka where the connector stores offsets for each source partition.”

This allows Kafka Connect toresumefrom the correct position on restart.

The other options (B–D) are not valid Kafka configs.

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.

Increasing partitions increasesparallelism, but also means:

Consumers in a group may have to handlemore partitions, especially if the number of consumers is lower than the number of partitions.

This can result inincreased lag, especially under high load.

FromKafka Topic Management Docs:

“Increasing the number of partitions increases consumer work, and if consumers can’t keep up, lag can accumulate.”

A is false:existing data is not redistributed.

B is false:records with the same key always map to the same partitionbased on hash.

D is not directly impacted by the partition count.
