Question #1215
A cloud practitioner needs to ensure low-latency DNS resolution and global traffic management for a multi-region application hosted on AWS. Which AWS service provides a scalable and highly available solution to meet this requirement?
Amazon Route 53
Amazon CloudFront
AWS Global Accelerator
Amazon API Gateway
Explanation
Amazon Route 53 (A) is AWS's DNS service designed for scalable, highly available DNS resolution and global traffic management. It supports latency-based routing, which directs users to the AWS region with the lowest network latency, fulfilling the requirement for a multi-region application.
Other options are incorrect because:
- B. Amazon CloudFront: A CDN that caches content at edge locations but does not manage DNS or global traffic routing.
- C. AWS Global Accelerator: Optimizes traffic routing via static Anycast IPs but does not handle DNS resolution.
- D. Amazon API Gateway: Manages API traffic but does not provide DNS or global traffic management.
Key Points: Route 53 combines DNS services with traffic management policies (e.g., latency, geolocation, weighted routing), making it ideal for multi-region applications requiring low-latency resolution and global traffic control.
Answer
The correct answer is: A
