Difficulty: EasyAWS Network Services

A startup is launching a new public website and needs to purchase a domain name and configure global Domain Name System (DNS) routing to direct users to their web application. Which AWS service provides both domain registration and DNS routing capabilities?

  1. A
    AWS Transit Gateway
  2. Amazon Route 53Answer
  3. C
    Amazon Simple Storage Service (Amazon S3)
  4. D
    Amazon Elastic Compute Cloud (Amazon EC2)

Answer

Amazon Route 53
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It translates user-friendly domain names into numeric IP addresses to route end users to internet applications, and it also acts as a domain registrar, allowing users to search for, purchase, and manage domain names in one place.

Step-by-Step Solution

1
Identify the core requirements: domain name registration (purchasing a domain) and global Domain Name System (DNS) routing (mapping domain names to IP addresses).
The target service must handle both DNS queries and domain registration.
This requirement rules out storage and compute services that do not provide networking name resolution.
2
Evaluate the AWS network services that fit the requirements.
Amazon Route 53 is identified as the correct service because it functions both as a registrar for buying domains and as a DNS service for routing users to web applications.
Other services like AWS Transit Gateway handle VPC transit routing rather than public DNS routing and registration.

Key Concept

Domain Name System (DNS) resolution and domain registration using Amazon Route 53.
