4. D. Enable the Backtrack feature during the creation of the DB cluste
5. E. Specify a target backtrack window of 48 hour
6. F. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basi
7. G. Configure the function to perform a backtrack operation.
8. H. Export a manual snapshot of the DB cluster to an Amazon S3 bucket after the data has been populated.Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basi
9. I. Configure the function to restore the snapshot from Amazon S3.
10. J. Set the DB cluster backup retention period to 2 day
11. K. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basi
12. L. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster.

Correct Answer: D
Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function on a daily basis. Configure the function to restore the DB cluster to a point in time and then delete the previous DB cluster. This is the most operationally efficient solution that meets the requirements, as it will allow the company to reset the database on a daily basis without having to manually take and restore snapshots. The other solutions (creating a manual snapshot of the DB cluster, enabling the Backtrack feature, or exporting a manual snapshot of the DB cluster to Amazon S3) will require additional steps and resources to reset the database on a daily basis.
