Confluent Certified Administrator for Apache Kafka CCAAK Exam Questions in PDF

Free Confluent CCAAK Dumps Questions (page: 3)

If a broker's JVM garbage collection takes too long, what can occur?

  1. There will be a trigger of the broker's log cleaner thread.
  2. ZooKeeper believes the broker to be dead.
  3. There is backpressure to, and pausing of, Kafka clients.
  4. Log files written to disk are loaded into the page cache.

Answer(s): B

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.



You are managing a Kafka cluster with five brokers (broker id '0', '1','2','3','4') and three ZooKeepers. There are 100 topics, five partitions for each topic, and replication factor three on the cluster. Broker id `0' is currently the Controller, and this broker suddenly fails.
Which statements are correct? (Choose three.)

  1. Kafka uses ZooKeeper's ephemeral node feature to elect a controller.
  2. The Controller is responsible for electing Leaders among the partitions and replicas.
  3. The Controller uses the epoch number to prevent a split brain scenario.
  4. The broker id is used as the epoch number to prevent a split brain scenario.
  5. The number of Controllers should always be equal to the number of brokers alive in the cluster.
  6. The Controller is responsible for reassigning partitions to the consumers in a Consumer Group.

Answer(s): A,B,C

Explanation:

Kafka relies on ZooKeeper's ephemeral nodes to detect if a broker (controller) goes down and to elect a new controller.
The controller manages partition leadership assignments and handles leader election when a broker fails.

The epoch number ensures coordination and avoids outdated controllers acting on stale data.



When a broker goes down, what will the Controller do?

  1. Wait for a follower to take the lead.
  2. Trigger a leader election among the remaining followers to distribute leadership.
  3. Become the leader for the topic/partition that needs a leader, pending the broker return in the cluster.
  4. Automatically elect the least loaded broker to become the leader for every orphan's partitions.

Answer(s): B

Explanation:

When a broker goes down, the Controller detects the failure and triggers a leader election for all partitions that had their leader on the failed broker. The leader is chosen from the in-sync replicas (ISRs) of each partition.



Which technology can be used to perform event stream processing? (Choose two.)

  1. Confluent Schema Registry
  2. Apache Kafka Streams
  3. Confluent ksqlDB
  4. Confluent Replicator

Answer(s): B,C

Explanation:

Kafka Streams is a client library for building real-time applications that process and analyze data stored in Kafka.
ksqlDB enables event stream processing using SQL-like queries, allowing real-time transformation and analysis of Kafka topics.



How can load balancing of Kafka clients across multiple brokers be accomplished?

  1. Partitions
  2. Replicas
  3. Offsets
  4. Connectors

Answer(s): A

Explanation:

Partitions are the primary mechanism for achieving load balancing in Kafka.
When a topic has multiple partitions, Kafka clients (producers and consumers) can distribute the load across brokers hosting these partitions.



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?

  1. acks=0
  2. acks=1
  3. acks=all
  4. acks=undefined

Answer(s): A

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.



Your Kafka cluster has four brokers. The topic t1 on the cluster has two partitions, and it has a replication factor of three. You create a Consumer Group with four consumers, which subscribes to t1.
In the scenario above, how many Controllers are in the Kafka cluster?

  1. One
  2. two
  3. three
  4. Four

Answer(s): A

Explanation:

In a Kafka cluster, only one broker acts as the Controller at any given time. The Controller is responsible for managing cluster metadata, such as partition leadership and broker status. Even if the cluster has multiple brokers (in this case, four), only one is elected as the Controller, and others serve as regular brokers. If the current Controller fails, another broker is automatically elected to take its place.



You want to increase Producer throughput for the messages it sends to your Kafka cluster by tuning the batch size (`batch size') and the time the Producer waits before sending a batch (`linger.ms').
According to best practices, what should you do?

  1. Decrease `batch.size' and decrease `linger.ms'
  2. Decrease `batch.size' and increase `linger.ms'
  3. Increase `batch.size' and decrease `linger.ms'
  4. Increase `batch.size' and increase `linger.ms'

Answer(s): D

Explanation:

Increasing batch.size allows the producer to accumulate more messages into a single batch, improving compression and reducing the number of requests sent to the broker. Increasing linger.ms gives the producer more time to fill up batches before sending them, which improves batching efficiency and throughput.
This combination is a best practice for maximizing throughput, especially when message volume is high or consistent latency is not a strict requirement.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

q. 289 - the correct answer should be b not d, since the question asks for the most secure way to provide access to a s3 bucket (a single one), and by principle of the least privilege you should not be giving access to all buckets.
