Question#1

To enhance compression, I can increase the chances of batching by using

A. acks=all

B. linger.ms=20

C. batch.size=65536

D. max.message.size=10MB

Explanation:
linger.ms forces the producer to wait before sending messages, hence increasing the chance of creating batches that can be heavily compressed.

Question#2

Where are KSQL-related data and metadata stored?

A. Kafka Topics

B. Zookeeper

C. PostgreSQL database

D. Schema Registry

Explanation:
metadata is stored in and built from the KSQL command topic. Each KSQL server has its own in-memory version of the metastore.

Question#3

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 session.timeout.ms

B. Decrease session.timeout.ms

C. Increase heartbeat.interval.ms

D. decrease max.poll.interval.ms

E. increase max.poll.interval.ms

F. Decrease heartbeat.interval.ms

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

Producers can set acks=1 to get acknowledgement from partition leader only.
