Confluent Certified Developer for Apache Kafka Certification Examination 認定 CCDAK 試験問題 (Q42-Q47):

質問 # 42
You are using JDBC source connector to copy data from a table to Kafka topic. There is one connector created with max.tasks equal to 2 deployed on a cluster of 3 workers. How many tasks are launched?

A. 0
B. 1
C. 2
D. 3

正解：A

解説：
JDBC connector allows one task per table.

質問 # 43
You create a topic named stream-logs with:
A replication factor of 3
Four partitions
Messages that are plain logs without a keyHow will messages be distributed across partitions?

A. The first message will always be written to partition 0.
B. Messages will be distributed round-robin among all the topic partitions.
C. All messages will be written to the same log segment.
D. Messages will be distributed among all the topic partitions with strict ordering.

正解：B

解説：
If a message key is not provided, Kafka's default partitioner uses round-robin distribution across available partitions.
From Kafka Producer Design:
"If no key is provided, the default partitioner distributes messages round-robin to available partitions." A is incorrect - not all go to partition 0.
C is invalid - Kafka doesn't group messages into one segment without a key.
D is false - ordering is not preserved across partitions without a key.
Reference: Kafka Producer Partitioner Behavior

質問 # 44
Select all the way for one consumer to subscribe simultaneously to the following topics - topic.history, topic.sports, topic.politics? (select two)

A. consumer.subscribe(Pattern.compile("topic\..*"));
B. consumer.subscribe(Arrays.asList("topic.history", "topic.sports", "topic.politics"));
C. consumer.subscribePrefix("topic.");
D. consumer.subscribe("topic.history"); consumer.subscribe("topic.sports"); consumer.subscribe("topic.politics");

正解：A、B

解説：
Multiple topics can be passed as a list or regex pattern.

質問 # 45
When using the Confluent Kafka Distribution, where does the schema registry reside?

A. As a separate JVM component
B. As an in-memory plugin on your Kafka Brokers
C. As an in-memory plugin on your Zookeeper cluster
D. As an in-memory plugin on your Kafka Connect Workers

正解：A

解説：
Schema registry is a separate application that provides RESTful interface for storing and retrieving Avro schemas.

質問 # 46
Which two statements are correct when assigning partitions to the consumers in a consumer group using the assign() API?
(Select two.)

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

正解：A、C

解説：
Using assign() gives manual control over partition assignment. In this mode:
B is true: The application chooses partitions directly without involving the group coordinator.
C is true: Since no group coordination occurs, no rebalancing happens if a consumer dies.
From Kafka 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() are mutually exclusive.
D is incorrect: Partitions don't need to be equal across topics.
Reference: Kafka Consumer Java API > assign() and subscribe()
