An online shopping company has a large inflow of shopping requests daily. As a result, there is a consistent load on the company's Amazon RDS database. A database specialist needs to ensure the database is up and running at all times. The database specialist wants an automatic notification system for issues that may cause database downtime or for configuration changes made to the database.
What should the database specialist do to achieve this? (Choose two.)

A. Create an Amazon CloudWatch Events event to send a notification using Amazon SNS on every API call logged in AWS CloudTrail. B. Subscribe to an RDS event subscription and configure it to use an Amazon SNS topic to send notifications. C. Use Amazon SES to send notifications based on configured Amazon CloudWatch Events events. D. Configure Amazon CloudWatch alarms on various metrics, such as FreeStorageSpace for the RDS instance. E. Enable email notifications for AWS Trusted Advisor.
