Question
A company deploys an application on AWS behind an internet-facing Application Load Balancer (ALB) in the us-west-2 Region. Amazon Route 53 manages DNS CNAME records for the application. The company is replicating its AWS infrastructure to the eu-west-2 Region. A SysOps administrator must implement a Route 53 configuration to distribute application traffic across both Regions. Which solution will meet these requirements with the LEAST application response time?
Options
- AApply a geolocation routing policy to the CNAME records of both ALBs.
- BApply a latency-based routing policy to the CNAME records of both ALBs.
- CCreate a multivalue answer routing policy. Add the public IP addresses for both ALBs.
- DCreate a new private hosted zone that includes a CNAME record for the ALB that is in eu-west-2.
Explanation
A latency-based routing policy in Amazon Route 53 directs traffic to the AWS Region that provides the lowest latency for the user. This ensures that users experience the fastest response times by being directed to the nearest available Region. Route 53 continuously monitors the latency of requests and routes users to the Region with the lowest latency. This setup helps optimize application response time while maintaining high availability. The ALBs in each Region ensure that traffic is handled efficiently once it reaches the AWS infrastructure.
