A DynamoDB table has Time to Live (TTL) enabled. A solution for processing items deleted by TTL needs to be implemented. What is the optimal solution to this requirement?

Answer options:

A.Enable continuous backups with point-in-time recovery for the table.
B.Enable DynamoDB Streams on the table.
C.Use CloudWatch Events to collect TTL delete events. Create a Lambda function to process the event. Configure the Lambda function as the target for CloudWatch Events.
D.Use CloudTrail to collect TTL delete events. Create a Lambda function to process the event. Create an SNS Topic and trigger a Lambda function to process the event.

Answer: B
Option A is incorrect because this solution would require creating a new DynamoDB table and restoring the DynamoDB table from backup to process the deleted records. It is not the optimal solution.
Option B is CORRECT because DynamoDB Streams can be used to collect and retain items deleted by TTL.
Option C is incorrect because CloudWatch Events does not collect events from DynamoDB.Option D is incorrect because CloudTrail does not collect items deleted by TTL. It only records log events performed on the DynamoDB service.
