To publish a 15 MB message, you must configure which broker/topic setting?

• A. replica.fetch.max.bytes=15728640
• B. max.poll.interval.ms=300000
• C. fetch.message.max.bytes=15728640
• D. message.max.bytes=15728640 (broker/topic config)

Answer: (D)

Kafka restricts how large a single message can be, and that limit is set on the broker as message.max.bytes. You can also raise it per topic with max.message.bytes if you want a specific topic to allow larger messages. To publish a 15 MB message, you need at least 15728640 bytes configured, either as the broker’s message.max.bytes or as the topic’s max.message.bytes. The other options control different behaviors—replica.fetch.max.bytes affects how much a follower fetches, max.poll.interval.ms is about consumer polling cadence, and fetch.message.max.bytes governs how much data a consumer fetches in a single request. They do not set the maximum size for a published message. If you’re using a producer, also ensure the producer’s max.request.size is at least 15728640 so the client request can carry the 15 MB payload.
