CCDAK Consumer Practice Questions
The free CCDAK: Confluent Certified Developer for Apache Kafka Certification Examination questions that deal with consumer, with answers and explanations. The full bank and the timed practice test cover every topic the exam asks about.
Question #3
A consumer starts and has auto.offset.reset=none, and the topic partition currently has data for offsets going from 45 to 2311. The consumer group has committed the offset 10 for the topic before. Where will the consumer read from?
Correct answer: C
Explanation
auto.offset.reset=none means that the consumer will crash if the offsets it's recovering from have been deleted from Kafka, which is the case here, as 10 < 45
Question #9
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)
Select 2 answers.
Correct answer: B, F
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
