Confluent Certified Developer for Apache Kafka Certification Examination Sample Questions:
1. An application is consuming messages from Kafka.
The application logs show that partitions are frequently being reassigned within the consumer group.
Which two factors may be contributing to this?
(Select two.)
A) There is a storage issue on the broker.
B) There is a slow consumer processing application.
C) The number of partitions does not match the number of application instances.
D) An instance of the application is crashing and being restarted.
2. (You need to send a JSON message on the wire. The message key is a string.
How would you do this?)
A) Specify a value serializer class for the JSON contents of the message's value. Set the key serializer class to JSON.
B) Specify a key serializer class for the JSON contents of the message's value. Set the value serializer class to null.
C) Specify a value serializer class for the JSON contents of the message's value. Set the key serializer class to null.
D) Specify a value serializer class for the JSON contents of the message's value. Set a key serializer for the string value.
3. Your Kafka cluster has five brokers. The topic t1 on the cluster has:
Two partitions
Replication factor = 4
min.insync.replicas = 3You need strong durability guarantees for messages written to topic t1.You configure a producer acks=all and all the replicas for t1 are in-sync.How many brokers need to acknowledge a message before it is considered committed?
A) 5
B) 4
C) 2
D) 3
4. 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) Add more consumers to increase the level of parallelism of the processing.
B) Decrease the max.poll.records property of consumers.
C) Add more partitions to the topic to increase the level of parallelism of the processing.
D) Increase the max.poll.records property of consumers.
5. Which two producer exceptions are examples of the class RetriableException? (Select two.)
A) LeaderNotAvailableException
B) NotEnoughReplicasException
C) RecordTooLargeException
D) AuthorizationException
