The statement that the default visibility timeout for Amazon Simple Queue Service (SQS) is 30 seconds is accurate. When a message is retrieved from an SQS queue, it becomes invisible to other consumers for the duration of the visibility timeout, preventing multiple consumers from processing the same message at the same time. By default, this timeout is set to 30 seconds, which allows applications to process the message within this time frame before it becomes visible again for other consumers.

The ability to adjust the visibility timeout is an important feature, as it allows developers to tailor the timeout duration based on the specific processing needs of their applications. While the visibility timeout can be extended or reduced, it is specifically set to 30 seconds for new queues unless changed by the user.
