(A company that uses five Elastic IP addresses does not want to request more from AWS. Which solution should be used to route requests to a healthy endpoint?)
To route requests to a healthy endpoint without requesting additional Elastic IP addresses, the company should register a DNS name to an auto-assigned public IP address using a service like Route 53. This leverages dynamic DNS to distribute traffic, reducing reliance on fixed EIPs. The WGU Cloud Deployment and Operations Study Guide (Section 3.1, Route 53) states, 'Registering a DNS name with an auto-assigned public IP in Route 53 allows traffic routing to healthy instances, avoiding the need for additional Elastic IP addresses.' TTL adjustment, route table edits, and Systems Manager are not relevant solutions.
