SAP-C02 Question 191
Select 2Your company is planning to deploy a global application with low latency requirements for users in North America, Europe, and Asia-Pacific. The application will use Amazon S3 for file storage, Amazon RDS for databases, and requires high availability. Which AWS Global Infrastructure approach should you implement to meet these requirements effectively?
- A
Use AWS Regions in North America, Europe, and Asia-Pacific to deploy the application components closest to users in those regions.
- B
Set up a single AWS Region and use Amazon CloudFront with an edge location in each user region for low-latency access to S3 objects.
- C
Deploy Amazon RDS in a single Region and use cross-Region read replicas to serve read requests closer to users.
- D
Use AWS Global Accelerator to route traffic dynamically to the closest healthy endpoint across Regions.
- E
Leverage Amazon S3 Transfer Acceleration to improve upload speeds globally.
Show answer and explanation
Correct answers: A, D
Explanation
To meet the low-latency and high-availability requirements for a global application, utilizing multiple AWS Regions ensures that application components are deployed closer to users. Additionally, AWS Global Accelerator provides intelligent traffic routing to the nearest healthy Region, further optimizing performance for global users. Other options either focus on specific services like S3 or database optimization but do not address the broader requirements for global application deployment.
- A. Correct.
This is correct because deploying application components in multiple AWS Regions ensures low latency and high availability for users in North America, Europe, and Asia-Pacific.
- B. Incorrect.
While Amazon CloudFront can reduce latency for static content in S3, relying on a single AWS Region for application components does not meet high availability and low latency requirements across multiple continents.
- C. Incorrect.
Using cross-Region read replicas can improve database read performance, but it does not address the deployment of application components or overall availability across multiple Regions.
- D. Correct.
This is correct because AWS Global Accelerator dynamically routes traffic to the closest healthy endpoint, reducing latency and improving availability for global users.
- E. Incorrect.
Amazon S3 Transfer Acceleration improves upload speeds for objects to S3 but does not address application deployment or database latency requirements.
