Just as an old saying goes, it is better to gain a skill than to be rich. Contemporarily, competence far outweighs family backgrounds and academic degrees.

Generally speaking, CCDAK certificates function as the fundamental requirement when a company needs to increase manpower in its start-up stage. In this respect, our CCDAK practice materials can satisfy your demands if you are now in preparation for a CCDAK certificate.

NEW QUESTION # 14
Which is true about topic compaction?
  • A. When a client produces a new event with an existing key, the broker immediately deletes the offset of the existing event.
  • 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. 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.
  • D. Compaction will keep exactly one message per key after compaction of inactive log segments.
Answer: D
Explanation:
Log compactionensures that Kafka retains at least thelatest value per keyin a topic. Compaction happensin the backgroundand removes older records with the same keyin inactive log segments, not immediately.
From theKafka Documentation > Log Compaction:
"Kafka guarantees that thelast message for each keywill be retained in the log after compaction, even if earlier messages with the same key are deleted." So, D is correct. A is incorrect because compaction does not overwrite; it's a background process. B is incorrect-deletion is not immediate. C incorrectly suggests client-side hashmap behavior.
Reference:Apache Kafka Log Compaction Docs

  • A. forward
  • B. full

(<1.9.1) if both are enums:** if the writer's symbol is not present in the reader's enum, then an error is signalled. **(>=1.9.1) if both are enums:
if the writer's symbol is not present in the reader's enum and the reader has a default value, then that value is used, otherwise an error is signalled.

NEW QUESTION # 17
You have a consumer group of 12 consumers and when a consumer gets killed by the process management system, rather abruptly, it does not trigger a graceful shutdown of your consumer. Therefore, it takes up to 10 seconds for a rebalance to happen. The business would like to have a 3 seconds rebalance time. What should you do? (select two)
  • A. increase max.poll.interval.ms
  • B. Decrease heartbeat.interval.ms
  • C. decrease max.poll.interval.ms
  • D. Decrease session.timeout.ms
  • E. Increase session.timeout.ms
  • F. Increase heartbeat.interval.ms
Answer: A,D
Explanation:
session.timeout.ms must be decreased to 3 seconds to allow for a faster rebalance, and the heartbeat thread must be quicker, so we also need to decrease heartbeat.interval.ms
