Which service provides a highly available and scalable DNS?

• A. Amazon CloudFront
• B. Amazon Route 53
• C. Amazon VPC
• D. Amazon API Gateway

Answer: (B)

Amazon Route 53 is the service that provides highly available and scalable Domain Name System (DNS) management. It is designed to route end users to Internet applications by translating human-friendly domain names, like www.example.com, into numeric IP addresses that computers use to connect with each other. Route 53 offers several features that contribute to its scalability and availability. It is built on a highly reliable infrastructure, ensuring low-latency responses and maintaining uptime through a global network of DNS servers. The service also supports a variety of routing policies, such as simple routing, weighted routing, latency-based routing, and geolocation routing, which allow users to manage traffic effectively based on their needs. In contrast, the other services listed do not provide DNS services. Amazon CloudFront is a content delivery network (CDN) that distributes content to users based on their geographic location. Amazon VPC (Virtual Private Cloud) allows users to create isolated virtual networks within the AWS cloud, and while it has networking capabilities, it does not specifically function as a DNS service. Amazon API Gateway is used for creating, publishing, and managing APIs, which is unrelated to DNS management. Thus, Amazon Route 53 stands out as the dedicated service for providing DNS functionality, ensuring high
