Question 87

A financial organization must ensure that the most current 90 days of MySQL database backups are accessible. Amazon RDS for MySQL DB instances are used to host all MySQL databases. A database expert must create a solution that satisfies the criteria for backup retention with the least amount of development work feasible.

Which strategy should the database administrator take?

Options:

Use AWS Backup to build a backup plan for the required retention period. Assign the DB instances to the backup plan.

Modify the DB instances to enable the automated backup option. Select the required backup retention period.

Automate a daily cron job on an Amazon EC2 instance to create MySQL dumps, transfer to Amazon S3, and implement an S3 Lifecycle policy to meet the retention requirement.

Use AWS Lambda to schedule a daily manual snapshot of the DB instances. Delete snapshots that exceed the retention requirement.
