ANS-C01 Question 7
Select 3Your organization runs a globally distributed web application with users accessing the application from different continents. You need to design a solution to ensure low latency, optimized user performance, and effective traffic management based on geography. Which AWS services and configurations should you incorporate?
- A
Use Amazon CloudFront with edge locations to cache content closer to users.
- B
Implement AWS Global Accelerator to route user traffic to the optimal endpoint based on geography and performance.
- C
Deploy multiple ALBs (Application Load Balancers) in each region and use Route 53 for latency-based routing.
- D
Leverage AWS Transit Gateway to route user traffic between edge locations and your on-premises data centers.
- E
Enable Amazon S3 Transfer Acceleration for dynamic content delivery across the globe.
Show answer and explanation
Correct answers: A, B, C
Explanation
To optimize user performance and traffic management for a globally distributed application, you need to utilize services that reduce latency and improve routing efficiency. Amazon CloudFront ensures cached content is delivered closer to users, AWS Global Accelerator routes traffic using the AWS global network for optimal performance, and latency-based routing in Route 53 directs users to the nearest or fastest regional endpoint. These services collectively address the requirements for low latency and effective global traffic management.
- A. Correct.
Amazon CloudFront provides a globally distributed network of edge locations that cache content closer to users, reducing latency and optimizing performance. This is a key service for edge network optimization.
- B. Correct.
AWS Global Accelerator uses the AWS global network to route traffic to the optimal endpoint based on geography and health, improving performance and availability for global applications.
- C. Correct.
Using multiple Application Load Balancers (ALBs) in different regions and configuring Route 53 for latency-based routing ensures that user requests are served from the region with the lowest latency, optimizing performance.
- D. Incorrect.
AWS Transit Gateway is used for interconnecting VPCs and on-premises networks but is not designed for edge network optimization or user traffic management for global architectures.
- E. Incorrect.
Amazon S3 Transfer Acceleration is specifically designed for data transfer optimization to S3 buckets, not for dynamic content delivery or global application traffic management.
