NEW QUESTION # 87
An ecommerce website maintains two topics - a high volume "purchase" topic with 5 partitions and low volume "customer" topic with 3 partitions. You would like to do a stream-table join of these topics. How should you proceed?

  • A. Repartition the purchase topic to have 3 partitions
  • B. Do a KStream / KTable join after a repartition step
  • C. Repartition customer topic to have 5 partitions
  • D. Model customer as a GlobalKTable

Answer: D

Explanation:
In case of KStream-KStream join, both need to be co-partitioned. This restriction is not applicable in case of join with GlobalKTable, which is the most efficient here.


NEW QUESTION # 88
You have a topic t1 in a Kafka cluster. A producer running on host A can successfully write messages to t1.
Then, you move that producer code to run on host B, but it fails writing messages to t1.
What is a likely reason for that failure?

  • A. Another producer started writing to t1.
  • B. Kafka ACLs are not configured to allow host B's IP address.
  • C. The producer is connecting to a different broker in the same cluster.
  • D. Topic T1 no longer exists in the same environment as host B.

Answer: B


NEW QUESTION # 89
An application is consuming messages from Kafka.
The application logs show that partitions are frequently being reassigned within the consumer group.
Which two factors may be contributing to this?
(Select two.)

  • A. There is a storage issue on the broker.
  • B. There is a slow consumer processing application.
  • C. An instance of the application is crashing and being restarted.
  • D. The number of partitions does not match the number of application instances.

Answer: B,C

Explanation:
Frequentrebalancesin a consumer group occur when:
* Consumers are too slowand miss heartbeats (A), or
* Instances crash or restart, triggering group membership changes (D)
FromKafka Consumer Group Coordination Docs:
"If a consumer fails to send a heartbeat in time (due to slowness or crash), it is removed from the group, causing a rebalance." Option B (partition mismatch) affectsload balancing, not rebalance frequency.
Option C (broker storage) doesn't trigger consumer rebalances.
Reference:Kafka Consumer Group Coordination and Heartbeats


NEW QUESTION # 90
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?

  • A. Hopping
  • B. Sliding
  • C. Session
  • D. Tumbling

Answer: C

Explanation:
Session windowsare ideal for trackingperiods of activity separated by inactivity, such as user sessions.
FromKafka Streams Documentation > Windowing:
"A session window captures streams of events that areintermittentand separated by agap of inactivity."
* Tumbling/Hopping/Sliding windows are fixed in size
* Session windows are dynamic and close after inactivity timeout
This makes them perfect for identifyinggaps in user interaction.
Reference:Kafka Streams Developer Guide > Session Windows


NEW QUESTION # 91
In Avro, adding an element to an enum without a default is a __ schema evolution

  • A. breaking
  • B. forward
  • C. backward
  • D. full

Answer: A

Explanation:
Since Confluent 5.4.0, Avro 1.9.1 is used. Since default value was added to enum complex type , the schema resolution changed from:
(<1.9.1) if both are enums:** if the writer's symbol is not present in the reader's enum, then an error is signalled. **(>=1.9.1) if both are enums:
if the writer's symbol is not present in the reader's enum and the reader has a default value, then that value is used, otherwise an error is signalled.
