CLF-C02 Question 212
Single answerYour company is hosting a web application on AWS and wants to ensure users can access it using a custom domain name (e.g., www.example.com). Additionally, you need to route traffic to the nearest AWS region for better performance. Which AWS service would fulfill these requirements?
- A
Amazon Route 53
- B
Amazon EC2 Auto Scaling
- C
AWS CloudFormation
- D
AWS Elastic Load Balancing
Show answer and explanation
Correct answer: A
Explanation
Amazon Route 53 is specifically designed for managing domain names and routing traffic to AWS resources or other endpoints. It supports latency-based routing, which helps direct users to the nearest AWS region for optimal performance, and integrates easily with custom domain names, making it the correct choice for this scenario.
- A. Correct.
Amazon Route 53 is a scalable Domain Name System (DNS) web service that helps map domain names to resources like web servers, and it supports routing traffic based on latency, geolocation, and other policies.
- B. Incorrect.
Amazon EC2 Auto Scaling is used to automatically adjust the number of EC2 instances in response to traffic patterns but does not handle DNS or routing traffic based on latency.
- C. Incorrect.
AWS CloudFormation is a service for managing infrastructure as code and deploying AWS resources in a repeatable way, but it does not manage DNS or traffic routing.
- D. Incorrect.
AWS Elastic Load Balancing distributes incoming traffic across multiple targets, such as EC2 instances, within a region but does not handle custom domain names or global traffic routing.
