최신 Confluent Certified Developer CCDAK 무료샘플문제:
1. (You are designing a stream pipeline to monitor the real-time location of GPS trackers, where historical location data is not required.
Each event has:
* Key: trackerId
* Value: latitude, longitude
You need to ensure that the latest location for each tracker is always retained in the Kafka topic.
Which topic configuration parameter should you set?)
A) retention.ms=infinite
B) min.cleanable.dirty.ratio=-1
C) cleanup.policy=compact
D) retention.ms=0
2. Which two producer exceptions are examples of the class RetriableException? (Select two.)
A) RecordTooLargeException
B) NotEnoughReplicasException
C) LeaderNotAvailableException
D) AuthorizationException
3. 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 redundancy in making the initial connection to the Kafka cluster.
C) It provides the ability to wake up dormant brokers.
D) It is the mechanism to distribute a topic's partitions across multiple brokers.
4. A producer is configured with the default partitioner. It is sending records to a topic that is configured with five partitions. The record does not contain any key.
What is the result of this?
A) Records will be sent to the least used partition.
B) Records will be sent to partition 0.
C) An error will be raised and no record will be sent.
D) Records will be dispatched among the available partitions.
5. Which is true about topic compaction?
A) Topic compaction does not remove old events; instead, when clients consume events from a compacted topic, they store events in a hashmap that maintains the latest value.
B) When a client produces a new event with an existing key, the old value is overwritten with the new value in the compacted log segment.
C) Compaction will keep exactly one message per key after compaction of inactive log segments.
D) When a client produces a new event with an existing key, the broker immediately deletes the offset of the existing event.
