Answer: Configure a new SQS standard queue as a dead-letter queue to isolate the faulty messages.
The correct answer is D. In this scenario, configuring a new SQS standard queue as a dead-letter queue will help isolate faulty messages from the main queue, ensuring that subsequent orders continue to be processed without interruption. Since the original queue is a standard queue, the dead-letter queue must also be a standard queue. Therefore, creating an SQS FIFO queue (option C) is incorrect. This ensures proper isolation and analysis of any faulty messages.
