Which two actions should you take to ensure proper error handling?
(Select two.)

A. Use a callback argument in producer.send() where you check delivery status.
B. Check the value of ProducerRecord.status().
C. Surround the call of producer.send() with a try/catch block to catch KafkaException.
D. Check that producer.send() returned a RecordMetadata object and is not null.

Answer: A,C

Explanation:
For proper delivery handling with acks=all:
* Usecallbackto log or act on success/failure.
* Usetry/catchto handle synchronous exceptions like serialization errors or network failures.
FromKafka Producer Documentation:
"Errors can be caught either via the returned Future<RecordMetadata> or via the callback interface. For fatal errors, use a try/catch block around the send call." Option B is incorrect because send() returns a Future, not RecordMetadata directly.
Option D is invalid - ProducerRecord has no method called status().
