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

Using assign() givesmanual controlover partition assignment. In this mode:

B is true: The applicationchooses partitionsdirectly without involving the group coordinator.

C is true: Since no group coordination occurs,no rebalancinghappens if a consumer dies.

FromKafka Consumer API Docs:

“assign() manually assigns a list of partitions to this consumer. No coordination takes place and no rebalancing is triggered.”

A is false: subscribe() and assign() aremutually exclusive.

D is incorrect: Partitions don't need to be equal across topics.

Kafka Connectsink connectorsuse thestandard Kafka consumer mechanismto track offsets, which means offsets are stored in the__consumer_offsets internal topic.

FromKafka Connect Documentation:

“Sink connectors are regular Kafka consumers and store their offsets in the __consumer_offsets topic like any other consumer.”

The other options refer tosource connectorsor worker configuration.

offsets.storage.topic is relevant forsource connectors.

TheStickyAssignortries to minimize partition movement bypreserving existing assignmentsas much as possible while still achieving a balanced assignment. This improvesconsumer stabilityand reduces rebalances.

From theKafka Consumer Assignor Documentation:

“The StickyAssignor attempts topreserve as many existing assignments as possible, which helps minimize partition movement between rebalances.”

RoundRobinAssignor focuses on even distribution, not stability.

RangeAssignor groups partitions by topic and assigns them consecutively, but can lead to imbalances.

PartitionAssignor is an abstract base class, not an assignor used directly.
