Question
A SysOps administrator needs to deploy an application in multiple AWS Regions. The application is behind an Application Load Balancer (ALB). The SysOps administrator must implement a solution that routes users to the Region that provides the lowest latency. In case of application failure, the solution must automatically route requests to a Region that has a healthy instance of the application. The company needs a solution with the shortest time to failover. Which solution will meet these requirements?
Options
- ACreate Amazon Route 53 MX records that have the same name for each endpoint. Use a latency
- BCreate Amazon Route 53 PTR records that have the same name for each endpoint. Use a
- CCreate an Amazon Route 53 A record alias that points to an AWS Global Accelerator standard
- DCreate a Network Load Balancer (NLB) in one Region. Create an Amazon Route 53 CNAME

Explanation
AWS Global Accelerator provides static IP addresses that serve as a fixed entry point for your applications. It automatically directs users to the optimal endpoint based on performance, routing traffic to the Region with the lowest latency. In addition, Global Accelerator continuously monitors the health of application endpoints and rapidly reroutes traffic to healthy Regions in the event of an application failure. By configuring endpoint groups for each Region and associating them with a listener, this solution minimizes failover time and meets both performance and resiliency
