SAP-C02 Question 483
Select 3Your organization operates a global e-commerce platform. You need to design an architecture that ensures low-latency access for users worldwide while maintaining high availability and fault tolerance. Which AWS Global Infrastructure features should you leverage to achieve this requirement?
- A
Deploy resources across multiple AWS Regions to ensure fault tolerance and low latency for global users.
- B
Use AWS Availability Zones within a single Region to ensure cross-regional fault tolerance.
- C
Leverage Amazon CloudFront to cache content at Edge Locations close to end users.
- D
Configure Amazon Route 53 with latency-based routing to direct users to the closest Region.
- E
Enable AWS Direct Connect for faster access to AWS resources from on-premises environments.
Show answer and explanation
Correct answers: A, C, D
Explanation
To ensure low-latency access for global users, you should deploy resources across multiple Regions, use Amazon CloudFront for edge caching, and configure Amazon Route 53 with latency-based routing. These AWS Global Infrastructure features work together to reduce latency, improve user experience, and provide fault tolerance. While Availability Zones and Direct Connect are important, they do not specifically address global low-latency access requirements.
- A. Correct.
Deploying resources across multiple AWS Regions ensures that users around the globe can access resources with low latency and provides fault tolerance by isolating workloads in different geographic areas.
- B. Incorrect.
AWS Availability Zones are designed for fault tolerance within a single AWS Region and do not enable cross-regional fault tolerance. This option does not meet the requirement for global low-latency access.
- C. Correct.
Amazon CloudFront caches content at Edge Locations worldwide, reducing latency for end users by serving content from locations closer to them.
- D. Correct.
Amazon Route 53 with latency-based routing directs users to the closest AWS Region, ensuring low-latency access for global users.
- E. Incorrect.
AWS Direct Connect provides a dedicated network connection between on-premises environments and AWS. While it improves connectivity, it is not directly relevant to achieving low latency for a global user base.
