AWS Certified Solutions Architect – Associate (SAA-C03) — Question 213

A company hosts its web application on AWS using seven Amazon EC2 instances. The company requires that the IP addresses of all healthy EC2 instances be returned in response to DNS queries.

Which policy should be used to meet this requirement?

Answer options

Correct answer: C

Explanation

The Multivalue routing policy is the correct choice because it allows for the return of multiple IP addresses for healthy resources, which meets the requirement of providing all healthy EC2 instance addresses. The Simple routing policy only returns one IP address, Latency routing policy focuses on minimizing latency by selecting the closest instance, and Geolocation routing policy directs traffic based on the geographic location of the user, which does not meet the stated requirement.
