Question 255

A company needs a strategy for failover and disaster recovery of its data and application. The application uses a MySQL database and Amazon EC2 instances. The company requires a maximum RPO of 2 hours and a maximum RTO of 10 minutes for its data and application at all times.

Which combination of deployment strategies will meet these requirements? (Choose two.)

Create an Amazon Aurora Single-AZ cluster in multiple AWS Regions as the data store. Use Aurora's automatic recovery capabilities in the event of a disaster.

Create an Amazon Aurora global database in two AWS Regions as the data store. In the event of a failure, promote the secondary Region to the primary for the application. Update the application to use the Aurora cluster endpoint in the secondary Region.

Create an Amazon Aurora cluster in multiple AWS Regions as the data store. Use a Network Load Balancer to balance the database traffic in different Regions.

Set up the application in two AWS Regions. Use Amazon Route 53 failover routing that points to Application Load Balancers in both Regions. Use health checks and Auto Scaling groups in each Region.

Set up the application in two AWS Regions. Configure AWS Global Accelerator to point to Application Load Balancers (ALBs) in both Regions. Add both ALBs to a single endpoint group. Use health checks and Auto Scaling groups in each Region.

Correct Answer: B, D

To meet the company's requirement of a maximum RPO of 2 hours and a maximum RTO of 10 minutes, a robust failover and disaster recovery strategy is necessary. Using Amazon Aurora global database in two AWS Regions provides the ability to quickly promote the secondary Region to primary and update the application endpoint, which ensures low RTO and RPO. Additionally, setting up the application in two AWS Regions with Amazon Route 53 failover routing, health checks, and Auto Scaling groups aids in maintaining application availability and quick failover, satisfying both RPO and RTO requirements.
