Confluent Certified Administrator for Apache Kafka Sample Questions (Q41-Q46):NEW QUESTION # 41
A Kafka cluster with three brokers has a topic with 10 partitions and a replication factor set to three. Each partition stores 25 GB data per day and data retention is set to 24 hours.
How much storage will be consumed by the topic on each broker?
  • A. 75 GB
  • B. 300 GB
  • C. 250 GB
  • D. 750 GB
Answer: B
Explanation:
10 partitions × 25 GB/day = 250 GB total per day for the topic (primary data).
With a replication factor of 3, there are 3 full copies of the data: 250 GB × 3 = 750 GB total across the entire cluster.
The cluster has 3 brokers, and Kafka tries to distribute replicas evenly among them: 750 GB ÷ 3 brokers = 250 GB per broker on average.
However, due to replication, some partitions have leaders and followers, so there's some overlap and not-perfect distribution. Each broker stores approximately 2/3 of the total topic data (since each broker holds replicas for around 2/3 of the partitions).
2/3 × 750 GB = 500 GB, but this is shared, so each broker ends up storing ~300 GB of replicated data, including its share of leaders and followers.

NEW QUESTION # 42
What are benefits to gracefully shutting down brokers? (Choose two.)
  • A. It will migrate any partitions the server is the leader for to other replicas prior to shutting down.
  • B. It will balance the partitions across brokers before restarting.
  • C. It will automatically re-elect leaders on restart.
  • D. It will sync all its logs to disk to avoid needing to do any log recovery when it restarts.
Answer: A,D
Explanation:
A graceful shutdown ensures that logs are flushed to disk, minimizing recovery time during restart.
Kafka performs controlled leader migration during a graceful shutdown to avoid disruption and ensure availability.

NEW QUESTION # 43
A company is setting up a log ingestion use case where they will consume logs from numerous systems. The company wants to tune Kafka for the utmost throughput.
In this scenario, what acknowledgment setting makes the most sense?
  • A. acks=undefined
  • B. acks=0
  • C. acks=all
  • D. acks=1
Answer: B
Explanation:
acks=0 provides the highest throughput because the producer does not wait for any acknowledgment from the broker. This minimizes latency and maximizes performance.
However, it comes at the cost of no durability guarantees - messages may be lost if the broker fails before writing them. This setting is suitable when throughput is critical and occasional data loss is acceptable, such as in some log ingestion use cases where logs are also stored elsewhere.

NEW QUESTION # 44
A developer is working for a company with internal best practices that dictate that there is no single point of failure for all data stored.
What is the best approach to make sure the developer is complying with this best practice when creating Kafka topics?
  • A. Use the parameter --partitions=3 when creating the topic.
  • B. Set 'min.insync.replicas' to 1.
  • C. Set the topic replication factor to 3.
  • D. Make sure the topics are created with linger.ms=0 so data is written immediately and not held in batch.
Answer: C
Explanation:
Replication factor determines how many copies of each partition exist across different brokers. A replication factor of 3 ensures that even if one or two brokers fail, the data is still available, thus eliminating a single point of failure.

NEW QUESTION # 45
A company has an existing Kafka cluster running without SSL/TLS enabled. The customer wants to enable SSL on brokers to secure data in transit, but they would like to give applications connecting to this cluster some time to migrate to using SSL connection instead of putting a hard stop.
Which solution will meet the customer's requirements?
  • A. Create a new listener with SSL enabled.
  • B. Enable SSL on the current listener, and do not implement SSL on application side.
  • C. Enable SSL on the current Listener, and do not enable mTLS.
  • D. Modify the advertised listeners setting on brokers to use SSL.
Answer: A
Explanation:
Kafka supports multiple listeners, allowing you to run PLAINTEXT and SSL simultaneously. By creating a new SSL-enabled listener (e.g., on a different port), existing applications can continue using PLAINTEXT while gradually migrating to the SSL listener. This approach avoids downtime and gives clients time to adapt without enforcing a hard cutover.
