Question 1 of 30

A company operates a mission-critical web application on AWS, utilizing Amazon RDS with a Multi-AZ deployment for its relational database. The application is designed to be highly available within its primary AWS Region. However, to mitigate the risk of a complete Region outage, the development team needs to implement a robust disaster recovery strategy that ensures minimal data loss and rapid recovery in a secondary AWS Region. They have already established an Amazon EC2 Auto Scaling group and an Elastic Load Balancer in the secondary Region, ready to host the application tier. What is the most effective strategy to ensure the database component of the application can be recovered and made operational in the secondary Region with minimal disruption?

Configure an Amazon RDS cross-Region read replica in the secondary Region and be prepared to promote it to a standalone database instance in case of a primary Region failure.
Implement Amazon S3 Cross-Region Replication for all application data and deploy a new, empty RDS instance in the secondary Region.
Launch a new EC2 instance in the secondary Region and restore the database from the most recent RDS snapshot.
Leverage the existing RDS Multi-AZ standby instance in the primary Region and expect it to automatically become active in the secondary Region during a Region-wide outage.
