Answer: By using the Time To Live feature with an expiration time attribute in DynamoDB.
The simplest way to automatically delete old items from an Amazon DynamoDB table is by using the Time To Live (TTL) feature. Option B is correct because TTL allows you to define an attribute that stores the expiration time for each item. Once the specified time has passed, DynamoDB automatically deletes the expired items, freeing up storage and reducing costs without the need for custom scripts or manual intervention.
