SAP-C02 Question 20
Select 4You are designing a global multi-region application architecture for a financial services company. The application requires low latency for end users across North America, Europe, and Asia-Pacific. The data must be replicated across regions to meet compliance requirements. You also need to minimize data transfer costs between regions and ensure high availability. Which combination of AWS services and features should you prioritize in your architecture?
- A
Deploy AWS Global Accelerator to optimize user traffic routing to the nearest region.
- B
Use Amazon S3 Cross-Region Replication to replicate data across regions.
- C
Leverage Amazon CloudFront to cache content globally at edge locations.
- D
Set up an AWS Direct Connect connection for each region to improve data transfer.
- E
Use Amazon Route 53 with latency-based routing to direct users to the nearest region.
- F
Deploy Amazon RDS Multi-AZ for automatic failover between regions.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To ensure low latency, high availability, and compliance for a global application, you should prioritize services like AWS Global Accelerator, Amazon S3 Cross-Region Replication, Amazon CloudFront, and Amazon Route 53 with latency-based routing. These services optimize performance and ensure data replication across regions while minimizing latency and meeting compliance requirements. AWS Direct Connect and Amazon RDS Multi-AZ are not suitable for meeting these specific requirements in this scenario.
- A. Correct.
AWS Global Accelerator improves application performance by routing traffic to the nearest healthy endpoint, ensuring low latency for global users.
- B. Correct.
Amazon S3 Cross-Region Replication ensures data is automatically copied to other regions, meeting compliance and disaster recovery requirements.
- C. Correct.
Amazon CloudFront caches content at edge locations, reducing latency for end users and improving global content delivery performance.
- D. Incorrect.
AWS Direct Connect is a private connection to AWS but is not related to minimizing data transfer costs between regions or improving global latency.
- E. Correct.
Amazon Route 53's latency-based routing allows traffic to be directed to the nearest region, ensuring low latency for end users.
- F. Incorrect.
Amazon RDS Multi-AZ provides high availability within a single region, not across multiple regions, making it unsuitable for this use case.
