Confluent Certified Administrator for Apache Kafka Sample Questions (Q20-Q25):NEW QUESTION # 20
You are managing a cluster with a large number of topics, and each topic has a lot of partitions. A team wants to significantly increase the number of partitions for some topics.
Which parameters should you check before increasing the partitions?
  • A. Check the producer batch size and buffer size.
  • B. Check the max open file count on brokers.
  • C. Check if compression is being used.
  • D. Check if acks=all is beina used.
Answer: B
Explanation:
Each Kafka partition maps to multiple log segment files, and each segment results in open file descriptors on the broker. When the number of partitions increases significantly, it can exceed the OS-level limit for open files per broker process, leading to failures or degraded performance. Therefore, it is essential to check and possibly increase the ulimit -n (max open files) setting on the broker machines.

NEW QUESTION # 21
Your organization has a mission-critical Kafka cluster that must be highly available. A Disaster Recovery (DR) cluster has been set up using Replicator, and data is continuously being replicated from source cluster to the DR cluster. However, you notice that the message on offset 1002 on source cluster does not seem to match with offset 1002 on the destination DR cluster.
Which statement is correct?
  • A. The offsets for the messages on the source, destination cluster may not match.
  • B. The message on DR cluster got over-written accidently by another application.
  • C. The message was updated on source cluster, but the update did not flow into destination DR cluster and errored.
  • D. The DR cluster is lagging behind updates; once the DR cluster catches up, the messages will match.
Answer: A
Explanation:
When using Confluent Replicator (or MirrorMaker), offsets are not preserved between the source and destination Kafka clusters. Messages are replicated based on content, but they are assigned new offsets in the DR (destination) cluster. Therefore, offset 1002 on the source and offset 1002 on the DR cluster likely refer to different messages, which is expected behavior.

NEW QUESTION # 22
Kafka Connect is running on a two node cluster in distributed mode. The connector is a source connector that pulls data from Postgres tables (users/payment/orders), writes to topics with two partitions, and with replication factor two. The development team notices that the data is lagging behind.
What should be done to reduce the data lag*?
The Connector definition is listed below:
{
"name": "confluent-postgresql-source",
"connector class": "PostgresSource",
"topic.prefix": "postgresql_",
& nbsp;& nbsp;& nbsp;...
"db.name": "postgres",
"table.whitelist": "users.payment.orders",
"timestamp.column.name": "created_at",
"output.data format": "JSON",
"db.timezone": "UTC",
"tasks.max": "1"
}
  • A. Increase the number of Connect Tasks (tasks max value).
  • B. Increase the number of Connect Nodes.
  • C. Increase the replication factor and increase the number of Connect Tasks.
  • D. Increase the number of partitions.
Answer: A
Explanation:
The connector is currently configured with "tasks.max": "1", which means only one task is handling all tables (users, payment, orders). This can create a bottleneck and lead to lag. Increasing tasks.max allows Kafka Connect to parallelize work across multiple tasks, which can pull data from different tables concurrently and reduce lag.

NEW QUESTION # 23
Which model does Kafka use for consumers?
  • A. Publish
  • B. Enrollment
  • C. Pull
  • D. Push
Answer: C
Explanation:
Kafka uses a pull model for consumers, where consumers poll the broker to retrieve messages at their own pace. This model gives consumers more control over flow and backpressure, improving scalability and reliability.

NEW QUESTION # 24
Which statements are correct about partitions? (Choose two.)
  • A. A partition in Kafka will be represented by a single segment on a disk.
  • B. All partition segments reside in a single directory on a broker disk.
  • C. A partition is comprised of one or more segments on a disk.
  • D. A partition size is determined after the largest segment on a disk.
Answer: B,C
