Question

A CloudOps engineer manages a stateless REST API served by eight EC2 instances spread across two Availability Regions, each registered with its own public IP. The team does not use a load balancer to save cost, but needs Route 53 to return multiple healthy endpoints per DNS query and automatically exclude any instance that fails its associated health check. Which Route 53 routing configuration meets these requirements?

Accepted Answer

Create multivalue answer routing records, each associated with a Route 53 health check, so DNS returns up to eight healthy records and omits unhealthy ones

Answer

Create a single simple routing record listing all eight IP addresses so the resolver randomly selects one

Answer

Create failover routing records with one primary and one secondary endpoint tied to health checks

Answer

Create weighted routing records with equal weights and no health checks so traffic is evenly distributed
