Question Title

* 2. A Kafka record is uniquely identified within the Partition by its:
(Choose 1)

Offset

Question Title

* 3. Which statement about Kafka topics is true?
(Choose 1)

Only a single producer can write data to a topic

Multiple consumers can subscribe to the data written to a topic

A consumer can insert data into any position within a topic

Question Title

* 4. Which statement about the lifetime of a Kafka record is true?
(Choose 1)

After a record is consumed, it becomes invisible to other Consumers for a defined invisibility period

A record is persisted until the defined retention period

A Consumer must delete processed records to prevent reprocessing

A Consumer must move the record to an internal topic for deletion

Question Title

* 5. Select all the kinds of data Kafka persists in ZooKeeper.
(Select ALL responses that apply)

Record headers

Access Control Lists

Broker SSL certificates

Consumer logic

Cluster metadata

Question Title

* 6. Kafka Producers convert data objects to arrays of bytes for transmission and storage. The process of converting data objects to byte arrays is called:
(Choose 1)

Serialization

Encryption

Externalization

Canonicalization

Question Title

* 7. Which setting of a Kafka Topic enables automatic failover when a server in the cluster fails?
(Choose 1)

Compression type

Segment index bytes

Partition count

Replication factor

Question Title

* 8. With the default settings of a Kafka Producer, which part of a record is used to determine its target Partition within the topic?
(Choose 1)

Record key

Record value

Header key

Record Timestamp

Question Title

* 9. Given the requirement to stream every record in a Kafka Topic to Elasticsearch for a search index, which technology would provide a scalable and reliable solution with no custom coding?
(Choose 1)

Producer API

Consumer API

Kafka Streams

Kafka Connect

Question Title

* 10. Which assignment of Partitions to Consumers in a Consumer Group is impossible when using default configurations?
(Choose 1)

Option A

Option B

Option C

Option D

Question Title

* 11. Select all techniques Kafka supports to encrypt data in transport.
(Select ALL responses that apply)

SSL

Producer encrypts data before sending, and then consumer decrypts data

PLAINTEXT

SASL

SSH

Question Title

* 12. Suppose Consumer c1 has just consumed message m1. Suppose Consumer c2 wants to consume m1 soon after. Assuming c1 and c2 are in different Consumer groups, which of the following is true?
(Choose 1)

Since m1 was consumed, it's no longer in the cluster, so it's impossible for c2 at this point

Consumer c2 can consume m1 just like c1 did

Since c1 had consumed m1 and advanced a Consumer offset, m1 is positioned beyond the offset where it can be consumed

None of the above

Question Title

* 13. Suppose a Producer has written a message to Kafka. That message can be changed:
(Choose 1)

Anytime, by any Producer

Only by the Producer who sent it to Kafka

Only to change its metadata

Never
