You are managing a Kafka cluster and notice that a producer is encountering a 'NotEnoughReplicas' exception. What is the reason for the 'NotEnoughReplicas' exception?

Question

Options

• AThe topic has insufficient in-sync replicas to satisfy the producer's acknowledgment requirements.
• BThe topic contains partitions that are currently under-replicated.
• CThe topic's observer replicas are not properly synchronized.
• DThe topic's log retention period is configured too low.

• A
  70% (14)
• B
  10% (2)
• C
  15% (3)
• D
  5% (1)

Explanation

The exception occurs when the number of in-sync replicas available for a partition is lower than the producer's required acknowledgment level. The producer cannot receive the required confirmations, so Kafka returns this error.
