Answer: Leverage DynamoDB's TTL feature using the 'expiration_date' to manage data expiration automatically.
The correct answer is D. Enabling TTL (Time to Live) on the DynamoDB table and specifying the expiration_date attribute allows DynamoDB to automatically manage and delete expired items, thereby minimizing development effort. This is a built-in feature specifically designed for such automated expiration and cleanup tasks, which does not require the additional setup or management of Lambda functions, Fargate tasks, or Glue jobs.
