Confluent Certified Developer for Apache Kafka Certification Examination Sample Questions:

1. Your application is consuming from a topic configured with a deserializer.
It needs to be resilient to badly formatted records ("poison pills"). You surround the poll() call with a try/catch for RecordDeserializationException.
You need to log the bad record, skip it, and continue processing.
Which action should you take in the catch block?

A) Log the bad record, no other action needed.
B) Throw a runtime exception to trigger a restart of the application.
C) Log the bad record and call the consumer.skip() method.
D) Log the bad record and seek the consumer to the offset of the next record.

2. (A consumer application needs to use an at-most-once delivery semantic.
What is the best consumer configuration and code skeleton to avoid duplicate messages being read?)

A) auto.offset.reset=earliest and enable.auto.commit=truewhile (true) {final var records = consumer.poll (POLL_TIMEOUT);consumer.commitAsync();for (var record : records) {// Any processing}}
B) auto.offset.reset=earliest and enable.auto.commit=falsewhile (true) {final var records = consumer.poll (POLL_TIMEOUT);for (var record : records) {// Any processing}consumer.commitAsync();}
C) auto.offset.reset=latest and enable.auto.commit=truewhile (true) {final var records = consumer.poll (POLL_TIMEOUT);for (var record : records) {// Any processing}consumer.commitAsync();}
D) auto.offset.reset=earliest and enable.auto.commit=falsewhile (true) {final var records = consumer.poll (POLL_TIMEOUT);consumer.commitAsync();for (var record : records) {// Any processing}}

3. Which two statements are correct when assigning partitions to the consumers in a consumer group using the assign() API?
(Select two.)

A) It is mandatory to subscribe to a topic before calling assign() to assign partitions.
B) The consumer chooses which partition to read without any assignment from brokers.
C) All topics must have the same number of partitions to use assign() API.
D) The consumer group will not be rebalanced if a consumer leaves the group.

4. Clients that connect to a Kafka cluster are required to specify one or more brokers in the bootstrap.servers parameter.
What is the primary advantage of specifying more than one broker?

A) It forces clients to enumerate every single broker in the cluster.
B) It provides the ability to wake up dormant brokers.
C) It is the mechanism to distribute a topic's partitions across multiple brokers.
D) It provides redundancy in making the initial connection to the Kafka cluster.

5. You have a topic with four partitions. The application reads from it using two consumers in a single consumer group.
Processing is CPU-bound, and lag is increasing.
What should you do?

A) Increase the max.poll.records property of consumers.
B) Add more partitions to the topic to increase the level of parallelism of the processing.
C) Add more consumers to increase the level of parallelism of the processing.
D) Decrease the max.poll.records property of consumers.
