An application needs to make use of an SQS queue for working with messages. An SQS queue has been created with the default settings. The application needs 60 seconds to process each message. Which of the following step need to be carried out by the application?

Answer options:

A.Change the VisibilityTimeout for each message and then delete the message after processing is completed.
B.Delete the message and change the visibility timeout.
C.Process the message, change the visibility timeout. Delete the message.
D.Process the message and delete the message.

Answer – A
If the SQS queue is created with the default settings, then the default visibility timeout is 30 seconds. And since the application needs more time for processing, you first need to change the timeout and delete the message after it is processed.
Option B is incorrect since you need to process the message first.
Options C and D are incorrect since you need to change the visibility timeout for each message first.
