Question: 1 / 400

Which of the following indicates that a replica is in-sync?

It has an active session with the leader

It has fetched messages within the last 5 seconds

It has sent a heartbeat to Zookeeper in the last 6 seconds

The correct choice denotes that a replica is considered in-sync when it has the same data as the leader. In the context of Kafka, a replica is marked as in-sync when it is capable of receiving and applying the same changes as the leader, ensuring that data remains consistent across the cluster. This synchronization is fundamental because it guarantees that the replicas can take over in the event that the leader fails, thus ensuring data durability and availability.

If a replica has successfully synchronized its data with the leader, it confirms that it is keeping up with the leader's logs and can serve as a reliable backup. The other indicators listed in the options do not necessarily guarantee that a replica's data matches that of the leader or that it is fully in sync, which is crucial for maintaining the integrity of the data within the Kafka environment.
