AWS Certified Cloud Practitioner — Question 369

A company wants to set up a Domain Name System (DNS) record for its application with a failover routing policy that is based on health checks.

Which AWS service or resource should the company use to achieve this goal?

Answer options

• A. Amazon Connect
• B. Application Load Balancer
• C. Amazon Route 53
• D. AWS WAF

Correct answer: C

Explanation

Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) service that supports failover routing policies integrated with health checks to redirect traffic away from unhealthy resources. While an Application Load Balancer distributes traffic at the application layer, it does not manage DNS records. Amazon Connect and AWS WAF serve entirely different purposes, namely cloud contact center management and web application security respectively.
