Select 3Your company has just launched a new web application, and you need to ensure that traffic is routed to the correct servers based on domain names. Additionally, you want to ensure high availability by routing traffic to healthy endpoints in case of server failures. Which of the following are use cases for Amazon Route 53 in this scenario?
- A
Registering domain names for the web application
- B
Routing traffic to different AWS Regions based on latency
- C
Managing SSL/TLS certificates for securing the web application
- D
Configuring health checks to route traffic to healthy endpoints
- E
Enabling automatic scaling of EC2 instances
Show answer and explanation
Correct answers: A, B, D
Explanation
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service that helps manage domain registration, traffic routing based on rules like latency, and health checks to ensure traffic is directed to healthy endpoints. It does not manage SSL/TLS certificates or automatic scaling, which are responsibilities of AWS Certificate Manager and Auto Scaling, respectively.
- A. Correct.
Amazon Route 53 can be used to register domain names, making it possible to associate your web application with a custom domain.
- B. Correct.
Route 53 supports latency-based routing, which directs users to the AWS Region with the lowest latency.
- C. Incorrect.
Managing SSL/TLS certificates is handled by AWS Certificate Manager, not Amazon Route 53.
- D. Correct.
Route 53 can perform health checks on endpoints and route traffic only to healthy ones, improving the availability of your application.
- E. Incorrect.
Automatic scaling of EC2 instances is managed by Auto Scaling Groups, not Amazon Route 53.
