SAP-C02 Question 189
Select 2Your organization operates a global e-commerce platform with customers across multiple continents. To improve latency and availability, you are tasked with designing a solution that leverages AWS Global Infrastructure. Which of the following approaches would you implement to meet this requirement?
- A
Distribute your application across multiple AWS Regions and use Route 53 for latency-based routing.
- B
Deploy your application in a single AWS Region and use CloudFront with an edge location near your customers.
- C
Use Amazon S3 Transfer Acceleration to reduce latency for uploading data to an S3 bucket in a single region.
- D
Implement AWS Global Accelerator to route traffic to optimal endpoints based on proximity.
- E
Deploy your application in multiple Availability Zones within a single Region to ensure high availability globally.
Show answer and explanation
Correct answers: A, D
Explanation
To optimize for global latency and availability, it is best to distribute your application across multiple AWS Regions and leverage latency-based routing with Amazon Route 53. Additionally, AWS Global Accelerator enhances performance by routing traffic to the best available endpoint based on proximity and availability. While CloudFront and Transfer Acceleration provide specific optimizations, they do not fully address the needs of a global, low-latency application.
- A. Correct.
This is correct. Distributing your application across multiple AWS Regions ensures that your application is closer to users in different parts of the world, reducing latency. Route 53's latency-based routing helps direct users to the region with the lowest latency.
- B. Incorrect.
This is partially correct but not ideal for meeting global low-latency requirements. While CloudFront can cache content at edge locations for lower latency, deploying your app in a single region does not guarantee optimal performance for users worldwide.
- C. Incorrect.
This is not correct. S3 Transfer Acceleration optimizes uploads to S3 buckets but does not address application latency or availability across global regions.
- D. Correct.
This is correct. AWS Global Accelerator enhances performance by routing traffic to the optimal endpoint based on user proximity and health of the application endpoints.
- E. Incorrect.
This is not correct. Deploying in multiple Availability Zones improves high availability within a single region but does not address global latency or availability.
