AWS Lambda functions can be configured to send unprocessed events to a dead-letter queue when the function fails to process the event successfully.
False
True
The correct answer is that AWS Lambda functions indeed can be configured to send unprocessed events to a dead-letter queue (DLQ) when the function fails to process them. This is an essential capability for error handling in AWS Lambda functions, allowing developers to set aside and later investigate the messages that caused failures in the processing. A DLQ helps to ensure that messages are not lost and provides a mechanism to deal with them after a predetermined number of retries have been exhausted, in contrast to leaving them unhandled or discarding them.
