질문 # 19
If I produce to a topic that does not exist, and the broker setting auto.create.topic.enable=true, what will happen?

A. Kafka will automatically create the topic with num.partitions=#of brokers and replication.factor=3
B. Kafka will automatically create the topic with the indicated producer settings num.partitions and default.
replication.factor
C. Kafka will automatically create the topic with the broker settings num.partitions and default.replication.
factor
D. Kafka will automatically create the topic with 1 partition and 1 replication factor

정답：C

설명：
The broker settings comes into play when a topic is auto created

질문 # 20
How will you find out all the partitions without a leader?

A. kafka-topics.sh --bootstrap-server localhost:2181 --describe --unavailable-partitions
B. kafka-topics.sh --zookeeper localhost:2181 --describe --under-replicated-partitions
C. kafka-topics.sh --zookeeper localhost:2181 --describe --unavailable-partitions
D. kafka-topics.sh --broker-list localhost:9092 --describe --under-replicated-partitions

정답：C

설명：
Please note that as of Kafka 2.2, the --zookeeper option is deprecated and you can now usekafka-topics.sh --bootstrap-server localhost:9092 --describe --unavailable-partitions

질문 # 21
Which is true about topic compaction?

A. Compaction will keep exactly one message per key after compaction of inactive log segments.
B. When a client produces a new event with an existing key, the broker immediately deletes the offset of the existing event.
C. 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.
D. 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.

정답：A

설명：
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

질문 # 22
How will you read all the messages from a topic in your KSQL query?

A. KSQL reads from the beginning of a topic, by default.
B. KSQL reads from the end of a topic. This cannot be changed.
C. Use KSQL CLI to set auto.offset.reset property to earliest

정답：C

설명：
Consumers can set auto.offset.reset property to earliest to start consuming from beginning. For KSQL, SET 'auto.offset.reset'='earliest';

질문 # 23
A producer just sent a message to the leader broker for a topic partition. The producer used acks=1 and therefore the data has not yet been replicated to followers. Under which conditions will the consumer see the message?

A. When the high watermark has advanced
B. When the message has been fully replicated to all replicas
C. Never, the produce request will fail
D. Right away

정답：A

설명：
The high watermark is an advanced Kafka concept, and is advanced once all the ISR replicates the latest offsets. A consumer can only read up to the value of the High Watermark (which can be less than the highest offset, in the case of acks=1)
