NEW QUESTION # 40
The rule "same key goes to the same partition" is true unless...
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 # 41

NEW QUESTION # 42
A stream processing application is tracking user activity in online shopping carts.
You want to identify periods of user inactivity.
Which type of Kafka Streams window should you use?
Answer: A
Explanation:
Session windows are ideal for tracking periods of activity separated by inactivity, such as user sessions.
From Kafka Streams Documentation > Windowing:
"A session window captures streams of events that are intermittent and separated by a gap of inactivity." Tumbling/Hopping/Sliding windows are fixed in size Session windows are dynamic and close after inactivity timeout This makes them perfect for identifying gaps in user interaction.
Reference: Kafka Streams Developer Guide > Session Windows

NEW QUESTION # 44
(You started a new Kafka Connect worker.
Which configuration identifies the Kafka Connect cluster that your worker will join?)
Answer: D
Explanation:
As documented in the official Apache Kafka Connect framework documentation, Kafka Connect workers form a logical cluster by using a Kafka consumer group. The configuration property that identifies this cluster is group.id.
All Kafka Connect workers configured with the same group.id automatically join the same Connect cluster.
Kafka's group coordination protocol is then used to distribute connector and task configurations among the workers, providing fault tolerance, scalability, and automatic rebalancing.
Option A (cluster.id) is a Kafka internal identifier used by brokers and is not configurable for Kafka Connect workers. Option B (worker.id) does not exist as a valid Kafka Connect configuration. Option D (connector.id) identifies individual connectors within a Connect cluster, not the worker cluster itself.
Therefore, the group.id property is the correct and officially documented configuration that determines which Kafka Connect cluster a worker belongs to.
