SAP-C02 Question 458
Select 3A global e-commerce company has customers across the world and wants to improve the performance of its web application by reducing latency for users in different regions. The application serves dynamic content, such as personalized product recommendations, and static content, such as images and CSS files. Additionally, the company needs to ensure that users are routed to the nearest healthy application endpoint for improved availability and fault tolerance. Which combination of AWS services should you use to meet these requirements?
- A
AWS Global Accelerator
- B
Amazon CloudFront
- C
Amazon S3 Transfer Acceleration
- D
AWS Direct Connect
- E
Amazon Route 53
Show answer and explanation
Correct answers: A, B, E
Explanation
To improve global application performance and availability, AWS Global Accelerator ensures users are routed to the nearest healthy endpoint using the AWS global network, which minimizes latency and enhances fault tolerance. Amazon CloudFront caches both static and dynamic content at edge locations closer to users, significantly reducing load times. Additionally, Amazon Route 53 enables latency-based routing to direct users to the closest application endpoint, further improving performance. Together, these services provide an optimal solution for the described use case.
- A. Correct.
AWS Global Accelerator provides a static IP address and uses the AWS global network to route traffic to the nearest healthy endpoint, improving performance and availability for the application.
- B. Correct.
Amazon CloudFront is a content delivery network (CDN) that caches both static and dynamic content at edge locations closer to users, reducing latency and improving content delivery performance.
- C. Incorrect.
Amazon S3 Transfer Acceleration is used to improve the upload speed of files to S3 buckets from distant locations, but it is not relevant in this scenario since the focus is on improving web application performance for end-users.
- D. Incorrect.
AWS Direct Connect provides a dedicated network connection between on-premises environments and AWS, which is unrelated to improving global application performance or routing user traffic.
- E. Correct.
Amazon Route 53 is a highly available DNS service that can route traffic to application endpoints based on routing policies like latency-based routing, making it suitable for directing users to the nearest endpoint.
