NEW QUESTION # 24
A consumer starts and has auto.offset.reset=latest, and the topic partition currently has data for offsets going from 45 to 2311. The consumer group has committed the offset 643 for the topic before. Where will the consumer read from?
- A. it will crash
- B. offset 45
- C. offset 2311
- D. offset 643
Answer: D
Explanation:
The offsets are already committed for this consumer group and topic partition, so the property auto.offset.reset is ignored
NEW QUESTION # 25
How do you create a topic named test with 3 partitions and 3 replicas using the Kafka CLI?
- A. bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 3 --partitions 3 --topic test
- B. bin/kafka-topics-create.sh --zookeeper localhost:9092 --replication-factor 3 --partitions 3 --topic test
- C. bin/kafka-topics.sh --create --bootstrap-server localhost:2181 --replication-factor 3 --partitions 3 --topic test
- D. bin/kafka-topics.sh --create --broker-list localhost:9092 --replication-factor 3 --partitions 3 --topic test
Answer: A
Explanation:
As of Kafka 2.3, the kafka-topics.sh command can take --bootstrap-server localhost:9092 as an argument. You could also use the (now deprecated) option of --zookeeper localhost:2181.
NEW QUESTION # 26
What happens if you write the following code in your producer? producer.send(producerRecord).get()
- A. Batching will be increased
- B. It will force all brokers in Kafka to acknowledge the producerRecord
- C. Compression will be increased
- D. Throughput will be decreased
Answer: D
Explanation:
Using Future.get() to wait for a reply from Kafka will limit throughput.
NEW QUESTION # 27
The rule "same key goes to the same partition" is true unless...
- A. the number of producer changes
- B. the replication factor changes
- C. the number of partition changes
- D. the number of kafka broker changes
Answer: C
Explanation:
Increasing the number of partition causes new messages keys to get hashed differently, and breaks the guarantee "same keys goes to the same partition". Kafka logs are immutable and the previous messages are not re-shuffled.
NEW QUESTION # 28
What Java library is KSQL based on?
- A. Kafka Connect
- B. Schema Registry
- C. Kafka Streams
- D. REST Proxy
Answer: C

- A. value
- B. partition
- C. bootstrap.servers

NEW QUESTION # 30
In Java, Avro SpecificRecords classes are
- A. automatically generated from an Avro Schema
- B. automatically generated from an Avro Schema + a Maven / Gradle Plugin

NEW QUESTION # 31

- A. _consumer_offset
- B. Topic name from offset.storage.topic
- C. Topic name from status.storage.topic
- D. Topic name from config.storage.topic
Answer: B
NEW QUESTION # 32
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?
- A. offset 10
- B. offset 45
- C. offset 2311
- D. it will crash
Answer: D
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
NEW QUESTION # 33
What is the risk of increasing max.in.flight.requests.per.connection while also enabling retries in a producer?
- A. Message order not preserved
- B. Reduce throughput
- C. Less resilient
- D. At least once delivery is not guaranteed
Answer: A
Explanation:
Some messages may require multiple retries. If there are more than 1 requests in flight, it may result in messages received out of order. Note an exception to this rule is if you enable the producer settingenable.idempotence=true which takes care of the out of ordering case on its own. Seehttps://issues.apache.org/jira/browse/KAFKA-5494

NEW QUESTION # 37
Your Kafka cluster has five brokers. The topic t1 on the cluster has two partitions, and it has replication.factor
= 4, min.insync.replicas = 3.

Answer: D
NEW QUESTION # 38
A consumer wants to read messages from a specific partition of a topic. How can this be achieved?
- A. Call assign() passing a Collection of TopicPartitions as the argument
- B. Call subscribe() passing TopicPartition as the argument
- C. Call subscribe(String topic, int partition) passing the topic and partition number as the arguments
Answer: A
Explanation:
assign() can be used for manual assignment of a partition to a consumer, in which case subscribe() must not be used. Assign() takes a collection of TopicPartition object as an argument https://kafka.apache.org/23
