C. 16 KB

D. 4 KB

Answer: A

Explanation:

With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is 8KB.

If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon Simp|eDB to hold the information and include the pointer to that information in the Amazon SQS message.

If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.
