The application requires an RPO of 2 hours and an RTO of 10 minutes. The app uses a MySQL database and EC2 web servers. Which combination of deployment choices will satisfy these recovery objectives? (Choose two.)

Correct answer: Create an Amazon Aurora global database with instances in two Regions to store data. If a Region fails, promote the secondary Region to be the primary for the application., Deploy the application in two Regions and use Route 53 failover routing to point to the Application Load Balancers in each Region. Use health checks to detect Region availability and Auto Scaling groups in each Region to scale capacity..
Why this is the answer
The RPO of 2 hours and RTO of 10 minutes require a multi-Region strategy. An Amazon Aurora global database provides fast cross-Region replication, enabling a low RPO and quick RTO by promoting a secondary Region. Deploying the application in two Regions with Route 53 failover routing and health checks allows for automatic detection of Region unavailability and redirection of traffic, meeting the RTO. Auto Scaling groups in each Region ensure capacity. Incorrect options: An Aurora cluster confined to a single AZ and multiple Regions is contradictory and doesn't leverage Aurora's global capabilities effectively for disaster recovery. An Aurora multi-master cluster across multiple Regions with a Network Load Balancer is not a standard or efficient pattern for disaster recovery; Aurora global database is designed for this. Deploying with a multi-Region Auto Scaling group behind Application Load Balancers doesn't inherently provide the RPO/RTO without explicit failover mechanisms like Route 53, and manually increasing desired count adds to RTO.
