A DNS design must send traffic to a primary endpoint when it is healthy and to a secondary endpoint only when the primary becomes unhealthy. Which Route 53 routing policy should be used?

Question

Accepted Answer

C. Failover routing. Route 53 failover routing is the active-passive model that sends traffic to a healthy primary resource and routes to a secondary resource when the primary is unhealthy. Latency-based routing chooses the lowest-latency endpoint, which is a different availability pattern.
