Explanation

Amazon Route 53 is AWS's purpose-built DNS (Domain Name System) service, designed from the ground up to be highly available and scalable - it operates across a global network of DNS servers with a 100% uptime SLA, making it the definitive choice for routing internet traffic to AWS workloads.

Why the distractors are wrong:

• B. Amazon Lightsail is a simplified virtual private server (VPS) service for hosting small applications - it has nothing to do with DNS management.
• C. AWS Amplify Hosting is a front-end web hosting and CI/CD platform for static sites and SPAs, not a DNS service.
• D. Amazon S3 is object storage for files, backups, and static website hosting - while it can host static sites, it is not a DNS service.

Memory tip: The number 53 is the well-known port for the DNS protocol - AWS named Route 53 after it intentionally. If an exam question mentions DNS, domain registration, or traffic routing, Route 53 is almost always the answer.
