Community Insight
The question tests knowledge of AWS managed network services, specifically identifying Route 53 as the dedicated DNS solution rather than generic compute or storage.
Amazon Route 53 is the highly available and scalable DNS web service required to connect users to a globally accessible ecommerce platform on AWS.
Candidates often select Amazon EC2 (A) because it hosts the application, failing to distinguish between the hosting infrastructure and the routing/DNS layer.

Expert Analysis
Why the Answer Is Correct
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service designed to route end-user requests to endpoints such as Amazon EC2 instances, AWS Elastic Load Balancers, or other resources. The requirement explicitly asks for a "highly available and scalable DNS web service," which is the exact definition and primary function of Route 53.Why the Other Options Are Wrong
Amazon EC2 (A) is a compute service used to host applications, not for DNS resolution. Amazon VPC (B) is a virtual network environment that isolates cloud resources but does not provide public DNS routing services. Amazon RDS (D) is a managed database service, completely unrelated to DNS or user routing.Community Comment Notes
Community consensus strongly supports Option C, with multiple users confirming that Route 53 is the correct DNS service. Comments emphasize its scalability and availability, aligning perfectly with the exam objective. One user noted it provides a "reliable and cost-effective way" to ensure access, reinforcing the global accessibility aspect.Official Reference
Exam Strategy
Focus on keyword mapping in exam questions: 'DNS' always points to Route 53, 'Compute' to EC2/Lambda, and 'Database' to RDS/DynamoDB. Distinguish between the service that hosts data and the service that routes traffic to it.
Frequently Asked Questions
Why isn't Amazon EC2 used for DNS?
EC2 is a compute service for hosting applications. While you can run DNS software on EC2, Route 53 is the managed, highly available service specifically designed for this purpose.
Does Route 53 support global routing?
Yes, Route 53 supports latency-based, geolocation, and global routing policies to direct users to the optimal endpoint based on their location.
