SAA-C03 Question 551
Single answerA company hosts a highly trafficked e-commerce website that needs to resolve domain names quickly and improve the application's availability and latency across a global customer base. Which AWS service should the Solutions Architect recommend to achieve this?
- A
Amazon Route 53
- B
Amazon CloudFront
- C
AWS Global Accelerator
- D
Elastic Load Balancer (ELB)
Show answer and explanation
Correct answer: A
Explanation
The best solution for resolving domain names and improving availability and latency for a global customer base is Amazon Route 53. It provides DNS resolution and supports features like latency-based routing, geolocation routing, and health checks, which are critical for a highly trafficked e-commerce website. Other services like CloudFront, Global Accelerator, and ELB are complementary and serve specific purposes, but they do not address domain name resolution directly.
- A. Correct.
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) service that can resolve domain names and route end users to the best-performing endpoints based on routing policies, making it the best choice for this use case.
- B. Incorrect.
Amazon CloudFront is a Content Delivery Network (CDN) used to distribute content globally with low latency. While it improves application performance, it does not handle domain name resolution.
- C. Incorrect.
AWS Global Accelerator improves application performance by routing traffic through AWS's global network infrastructure, but it is not designed for DNS resolution.
- D. Incorrect.
Elastic Load Balancer (ELB) distributes incoming application traffic, but it does not provide DNS services or help resolve domain names.
