Confluent CCDAK Exam - Topic 1 Question 12 Discussion

Actual exam question for Confluent's CCDAK exam

Question #: 12
Topic #: 1

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)

AIncrease session.timeout.ms

BDecrease session.timeout.ms

CIncrease heartbeat.interval.ms

Ddecrease max.poll.interval.ms

Eincrease max.poll.interval.ms

FDecrease heartbeat.interval.ms

Show Suggested Answer

Suggested Answer: B, E

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

Increasing max.poll.interval.ms doesn't make sense here.

I'm a bit confused about max.poll.interval.ms. I thought increasing it would help, but now I'm not so sure if that's the right move for a quicker rebalance.

I remember practicing a similar question where adjusting heartbeat.interval.ms helped with responsiveness. Maybe we should consider that here too.

I think we need to decrease session.timeout.ms to make the rebalance happen faster, but I'm not entirely sure about the second option.

I feel like decreasing heartbeat.interval.ms could be a good choice, but I need to double-check how that interacts with session.timeout.ms.

I'm a little confused by the wording of this question. The description doesn't exactly match the answer choices provided. I'll have to re-read it a few times and see if I can figure out the right method.

Okay, let me think this through. If the stakeholders aren't participating, then we need to find a way to better engage them. I'd say Stakeholder Engagement is the most logical choice here.

This one seems pretty straightforward. I'm pretty confident that the answer is B - seven-year MACRS property used in a corporation's trade or business.
