SAP-C02 Question 455
Select 2A global e-commerce company wants to improve the performance and availability of its application for users around the world. The application serves dynamic and static content, and the company needs to minimize latency and improve fault tolerance. Additionally, the solution should allow traffic to be routed to the nearest available endpoint while automatically adjusting for changes in endpoint health or performance. Which combination of AWS services should the company use?
- A
AWS Global Accelerator
- B
Amazon CloudFront
- C
AWS Elastic Load Balancer (ELB)
- D
Amazon Route 53 Geolocation Routing
- E
Amazon S3 Transfer Acceleration
Show answer and explanation
Correct answers: A, B
Explanation
To address the company's requirements for improved performance, reduced latency, and fault tolerance for global users, a combination of AWS Global Accelerator and Amazon CloudFront is the most suitable solution. AWS Global Accelerator optimizes traffic routing and ensures high availability by directing users to the nearest healthy endpoint. Amazon CloudFront reduces latency by caching static and dynamic content at edge locations, improving the user experience and offloading traffic from origin servers. Together, these services meet the company's global performance and fault tolerance needs.
- A. Correct.
AWS Global Accelerator optimizes traffic routing by directing traffic to the nearest healthy endpoint using the AWS global network. It provides improved performance and fault tolerance, making it an ideal choice for global applications.
- B. Correct.
Amazon CloudFront is a content delivery network (CDN) that caches static assets at edge locations, reducing latency for users worldwide. It also supports dynamic content delivery and integrates with other AWS services like S3 and Lambda@Edge.
- C. Incorrect.
AWS Elastic Load Balancer (ELB) operates within a single region or VPC and does not provide global traffic routing or edge location caching functionalities. While it helps with distributing traffic within a region, it does not meet the global latency reduction requirement.
- D. Incorrect.
Amazon Route 53 Geolocation Routing helps route traffic based on the geographic location of users, but it does not automatically adjust for endpoint health or performance, nor does it optimize traffic latency across the AWS global network.
- E. Incorrect.
Amazon S3 Transfer Acceleration speeds up uploads to S3 buckets by utilizing the AWS global network, but it does not address the need for global traffic routing or dynamic content delivery.
