ANS-C01 Question 18
Single answerYou are designing a global application with users in North America, Europe, and Asia. The application requires low latency, high availability, and the ability to automatically route traffic to the nearest healthy endpoint. Which solution would best meet these requirements?
- A
Use AWS Global Accelerator to route traffic to the nearest healthy endpoint based on latency.
- B
Use Amazon Route 53 with latency-based routing to direct users to the nearest region.
- C
Use an Application Load Balancer (ALB) with cross-region load balancing enabled.
- D
Deploy CloudFront distributions in each region to cache data and serve user requests.
Show answer and explanation
Correct answer: A
Explanation
AWS Global Accelerator is specifically designed for global traffic management, automatically routing users to the nearest healthy endpoint based on latency. It ensures better performance and availability compared to other solutions, making it the most suitable choice for this scenario. Other options, such as Route 53 latency-based routing or CloudFront, address specific use cases but do not fully meet the requirements for low latency, high availability, and global routing to healthy endpoints.
- A. Correct.
AWS Global Accelerator provides global traffic management, routing users to the nearest healthy endpoint based on latency while offering improved availability and performance.
- B. Incorrect.
While Route 53 latency-based routing can direct traffic to the nearest region, it does not provide the same level of consistent performance optimization and automatic failover as AWS Global Accelerator.
- C. Incorrect.
Application Load Balancer does not natively support global traffic management or routing users to the nearest region; it is designed for regional traffic management.
- D. Incorrect.
CloudFront is a content delivery network (CDN) designed to cache and serve static or dynamic content, not for routing global application traffic to the nearest healthy endpoint.
