Confluent Certified Administrator for Apache Kafka (CCAAK) — Question 4

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?

Answer options

Correct answer: C

Explanation

The topic has 10 partitions, each storing 25 GB of data per day, leading to a total of 250 GB for all partitions. With a replication factor of three, this data is replicated across three brokers, resulting in 250 GB per broker, or 300 GB considering the retention of 24 hours of data. The other options are incorrect as they do not account for the replication factor correctly.
