AWS Certified Cloud Practitioner — Question 491

A company has deployed its publicly accessible application in two different AWS Regions. The company has designated one Region as primary and the other Region as secondary for disaster recovery purposes.

Which AWS service or resource can automatically divert all incoming application requests to the secondary Region?

Answer options

• A. Application Load Balancer
• B. Amazon Route 53
• C. AWS Direct Connect
• D. AWS VPN

Correct answer: B

Explanation

Amazon Route 53 supports active-passive failover routing configurations using health checks, which can automatically redirect global DNS traffic to a secondary disaster recovery Region if the primary Region becomes unhealthy. Application Load Balancers are regional resources and cannot inherently route traffic across different AWS Regions. AWS Direct Connect and AWS VPN are networking services designed to connect on-premises environments to AWS, not for global application traffic routing.
