CCAAK Exam Dumps : Confluent Certified Administrator for Apache Kafka

For maximum throughput and lowest latency, the setting acks=0 allows the producer to send messages without waiting for any acknowledgment from the broker. This increases speed but at the cost of durability.

From Kafka documentation:

“acks=0: The producer does not wait for any acknowledgment from the broker. The message can be lost but offers the highest throughput.”

A → Correct: Maximizes throughput with no delivery guarantee.

B → Balanced option but not max throughput.

C → Offers strongest durability but lowest throughput.

D → Invalid configuration.

Kafka supports quotas to limit the broker resources each client can use. This is used to prevent one client from monopolizing cluster bandwidth.

From Kafka documentation:

“Quotas can be applied to both producers and consumers. These quotas are enforced based on the number of bytes per second, and they are applied to ensure fair usage of broker resources.”

A. Quotas → Correct: Admins can define quotas on throughput per client ID or user.

B. Consumer Groups → Incorrect: This controls parallelism in consumption but not resource fairness.

C. Rebalancing → Incorrect: This helps with load balancing but not with resource limitation.

D. ACLs → Incorrect: ACLs define access permissions but not resource usage.

Replication in Kafka ensures that partition data is copied across multiple brokers. This guarantees durability (data survives broker failure) and availability (other replicas can serve as leader if current leader fails).

From Kafka documentation:

“Replication ensures that data is not lost if a broker crashes and that messages remain available even during broker outages.”

B → Correct: Ensures persisted data even after failure.

C → Correct: Allows partition leader failover.

A → Incorrect: Replication may slightly reduce performance.

D → Incorrect: Replication is not a security mechanism.
