ANS-C01 Question 418
Select 3You are designing a highly available application that must handle millions of requests per second and distribute traffic globally with low latency. The application is hosted on multiple AWS Regions, and you want to direct users to the nearest Region based on their geographic location. Which combination of AWS services would best meet this requirement?
- A
Amazon Route 53 with Geolocation Routing
- B
Elastic Load Balancer (ELB) with Application Load Balancer (ALB) deployed in each Region
- C
Amazon CloudFront with edge locations
- D
AWS Global Accelerator
- E
Amazon EC2 Auto Scaling for each Region
Show answer and explanation
Correct answers: A, B, C
Explanation
To achieve low-latency traffic distribution globally, Route 53 with Geolocation Routing directs users to the nearest Region. Within each Region, Application Load Balancers distribute traffic across instances. Additionally, CloudFront can further reduce latency by caching content at edge locations. While AWS Global Accelerator and Auto Scaling are useful for improving performance and availability, they do not directly fulfill the specific scenario requirements for global traffic distribution and geolocation-based routing.
- A. Correct.
Amazon Route 53 with Geolocation Routing can direct users to the nearest AWS Region based on their geographic location. This ensures low-latency traffic routing.
- B. Correct.
Elastic Load Balancer (ELB) with Application Load Balancer (ALB) in each Region provides scalable load balancing for application traffic within each Region.
- C. Correct.
Amazon CloudFront with edge locations helps to cache and serve content closer to users, reducing latency for static and dynamic content.
- D. Incorrect.
AWS Global Accelerator is designed for improving performance and availability of global applications, but it is not a direct replacement for Geolocation Routing in this scenario.
- E. Incorrect.
Amazon EC2 Auto Scaling ensures high availability within each Region but does not address global traffic distribution or routing.
