Answer: Using Amazon SQS FIFO queue with an AWS Lambda function for message processing.
The correct answer is A. Amazon Simple Queue Service (Amazon SQS) FIFO queues are designed to ensure the order of message processing, which is essential for maintaining the specific order of event data. By setting up an AWS Lambda function to process messages from the FIFO queue, you can achieve this with minimal operational overhead because the integration between SQS and Lambda is managed by AWS, reducing the need for manual intervention and maintenance. Other options do not guarantee message order or might involve additional operational complexity.
