Question #961
A company is deploying a worldwide application that requires a managed DNS service to ensure high availability, scalability, and low-latency domain name resolution for users across different regions. Which AWS service should the company use to meet these requirements?
Amazon CloudFront
Amazon S3
Amazon Route 53
AWS Lambda
Explanation
Amazon Route 53 (C) is AWS's scalable and highly available Domain Name System (DNS) service. It is specifically designed to provide reliable and low-latency domain name resolution by routing users to the optimal AWS or external endpoints based on geographic location, health checks, and configured routing policies. This makes it ideal for global applications requiring worldwide coverage.
Why other options are incorrect:
- A. Amazon CloudFront: A content delivery network (CDN) that caches content at edge locations to reduce latency, but it does not manage DNS resolution.
- B. Amazon S3: A storage service for static files and website hosting, but it does not handle DNS routing.
- D. AWS Lambda: A serverless compute service for running code without managing servers, unrelated to DNS management.
Key Points:
- Route 53 supports features like latency-based routing, health checks, and geographic DNS routing.
- Managed DNS services ensure high availability and scalability, critical for global applications.
- The question emphasizes domain name resolution, which is Route 53's core function.
Answer
The correct answer is: C
