SAP-C02 Question 457
Select 4A global e-commerce company wants to improve the performance and availability of its application for its worldwide customer base. The application hosts dynamic and static content, and it needs low-latency access for users across multiple continents. Additionally, the company requires DDoS protection and a mechanism to route users to the nearest healthy application endpoint during outages. Which combination of AWS services should you recommend?
- A
Amazon CloudFront
- B
AWS Global Accelerator
- C
Amazon Route 53
- D
AWS Shield Advanced
- E
Amazon ElastiCache
Show answer and explanation
Correct answers: A, B, C, D
Explanation
To meet the requirements of improved performance, availability, DDoS protection, and routing users to the nearest healthy endpoint, a combination of Amazon CloudFront, AWS Global Accelerator, Amazon Route 53, and AWS Shield Advanced is ideal. CloudFront improves latency by caching content at edge locations, Global Accelerator ensures low-latency routing to the nearest endpoint, Route 53 provides intelligent DNS routing, and Shield Advanced offers enhanced DDoS protection. While Amazon ElastiCache can optimize application performance, it does not address the global, low-latency, or DDoS protection requirements outlined in the scenario.
- A. Correct.
Amazon CloudFront is a content delivery network (CDN) that caches both static and dynamic content at edge locations, improving latency and performance for global users.
- B. Correct.
AWS Global Accelerator provides global traffic management, directing users to the nearest healthy application endpoint using Anycast IP addresses. It also improves performance and availability.
- C. Correct.
Amazon Route 53 is a highly available and scalable DNS service that can route traffic based on latency, geolocation, or health checks, ensuring users connect to the best endpoint.
- D. Correct.
AWS Shield Advanced offers advanced protection against DDoS attacks, which is essential for securing global applications from potential threats.
- E. Incorrect.
Amazon ElastiCache is a caching service for improving application performance but does not address global traffic management, DDoS protection, or routing. This makes it less relevant to the scenario.
