ANS-C01 Question 5
Select 2You are designing a global application with users distributed across North America, Europe, and Asia. The application requires low latency and high availability. Additionally, the application serves dynamic content and must efficiently manage user traffic to the nearest and healthiest endpoint. Which combination of AWS edge network services should you implement to meet these requirements?
- A
Amazon Route 53 latency-based routing
- B
AWS Global Accelerator
- C
Amazon CloudFront with an origin in a single AWS Region
- D
Elastic Load Balancer with cross-region load balancing enabled
- E
Amazon Route 53 geolocation routing
Show answer and explanation
Correct answers: A, B
Explanation
The combination of Amazon Route 53 latency-based routing and AWS Global Accelerator provides an optimal solution for a global application requiring low latency and high availability. Route 53 ensures that user requests are routed to the endpoint with the lowest latency, while Global Accelerator improves the performance of traffic routing to the nearest AWS edge location and dynamically manages user traffic to healthy endpoints. Other options, like CloudFront and geolocation routing, are less suitable for dynamic content optimization and latency-sensitive applications.
- A. Correct.
Amazon Route 53 latency-based routing ensures that user requests are directed to the endpoint with the lowest network latency, improving overall performance for global users.
- B. Correct.
AWS Global Accelerator optimizes traffic routing to the nearest AWS edge location and improves performance and availability using Anycast. It is ideal for dynamic content and global applications.
- C. Incorrect.
Amazon CloudFront is designed for caching static content at edge locations, not dynamic content. Using a single origin would not optimize performance for global users.
- D. Incorrect.
Elastic Load Balancer with cross-region load balancing can distribute traffic between regions, but it doesn't handle edge optimizations or dynamic routing based on user proximity.
- E. Incorrect.
Amazon Route 53 geolocation routing directs traffic based on the user’s geographic location, but it does not account for actual network latency, which is critical for optimizing performance.
