What is the purpose of a Route in OpenShift?

• A. To configure internal network policies.
• B. To monitor pod metrics.
• C. To expose an application to external clients by mapping a DNS name to a service.
• D. To manage image tags.

Answer: (C)

In OpenShift, a Route is used to expose an application to external clients by mapping a DNS name to a service. The router watches Routes and configures the underlying load balancer to direct external traffic that matches the host (and optional path) to the Service’s pods, enabling access from outside the cluster. This setup often allows TLS termination at the router and convenient DNS-based access to your app. It’s not about internal network policies, pod metrics, or image tag management, which are separate functions. So the Route’s purpose is to provide external exposure of an app by linking a DNS name to a Service.
