Confluent Certified Administrator for Apache Kafka Sample Questions (Q11-Q16):NEW QUESTION # 11
If a broker's JVM garbage collection takes too long, what can occur?
  • A. There is backpressure to, and pausing of, Kafka clients.
  • B. There will be a trigger of the broker's log cleaner thread.
  • C. Log files written to disk are loaded into the page cache.
  • D. ZooKeeper believes the broker to be dead.
Answer: D
Explanation:
If the broker's JVM garbage collection (GC) pause is too long, it may fail to send heartbeats to ZooKeeper within the expected interval. As a result, ZooKeeper considers the broker dead, and the broker may be removed from the cluster, triggering leader elections and partition reassignments.

NEW QUESTION # 12
Which statements are correct about partitions? (Choose two.)
  • A. A partition in Kafka will be represented by a single segment on a disk.
  • B. A partition is comprised of one or more segments on a disk.
  • C. All partition segments reside in a single directory on a broker disk.

What is the correct permission check sequence for Kafka ACLs?
  • A. Super Users -> Allow ACL -> Deny ACL-> Deny
  • B. Super Users -> Deny ACL -> Allow ACL -> Deny
  • C. Deny ACL -> Deny -> Allow ACL -> Super Users
  • D. Allow ACL -> Deny ACL -> Super Users -> Deny
Answer: A
Explanation:
Kafka checks permissions in the following sequence:
1. Super Users: If the user is a super user (defined via super.users), access is granted immediately.
2. Allow ACL: If there is a matching Allow ACL, Kafka proceeds to the next step.
3. Deny ACL: If there is a matching Deny ACL, access is denied (even if an Allow exists).
4. Deny: If no matching ACLs are found, access is denied by default.
This order ensures that super users bypass ACLs, denials override allows, and default is deny.

How can authentication for both internal component traffic and external client traffic be accomplished?
  • A. Configure multiple listeners on the broker.

* Use a separate listener for external clients (e.g., producers and consumers) with a different protocol (e.g., SSL or SASL_SSL).
