Why does Kafka use ZooKeeper? (Choose two.)

ATo access information about the leaders and partitions

BTo scale the number of brokers in the cluster

CTo prevent replication between clusters

DFor controller election

Show Suggested Answer

Suggested Answer: A, D

ZooKeeper stores metadata such as partition leadership and ISR (in-sync replicas), which brokers use to coordinate.

Kafka uses ZooKeeper to perform leader election for the Controller broker, which manages cluster metadata and leadership changes.

Zookeeper is Kafka's personal assistant, handling all the administrative tasks so Kafka can focus on the important stuff.

Kafka uses Zookeeper to keep track of its brokers, like a mom keeping tabs on her kids.

Zookeeper is like the bouncer at the Kafka party, making sure only the right brokers get in.

I’m a bit confused; I thought ZooKeeper was mainly for managing cluster state, which might relate to A and D, but I need to double-check that.

I feel like I’ve seen questions about replication and clusters before, but I don’t think ZooKeeper prevents replication. So I’m leaning towards A and D.

I remember something about ZooKeeper managing broker information, so A seems right. But I can't recall if it helps with scaling.

I think Kafka uses ZooKeeper for leader election, so I might go with D. But I'm not sure about the second option.

Ugh, I'm drawing a blank on the Kafka-ZooKeeper relationship. Guess I'll have to review my notes and try to reason through the options.

I've got this! Kafka uses ZooKeeper to access info about the leaders and partitions, and also for controller election to manage the cluster.

Okay, let me see. I remember ZooKeeper is used for things like coordination and configuration in distributed systems. So it makes sense it would be used for managing the Kafka cluster in some way.

Hmm, I'm a bit unsure about this one. I know ZooKeeper is used for coordination, but I can't remember the specifics for Kafka. Guess I'll have to think it through.

I think I know this one! Kafka uses ZooKeeper for leader election and to access info about the cluster.
