To determine if a service is correctly routing traffic to the appropriate Pods, the use of the command `kubectl get endpoints <service-name>` is particularly effective. This command retrieves information about the endpoints associated with a specific service, which are the actual Pods that are targeted for network traffic.

When a service is created in Kubernetes, it maintains a list of endpoints that represent the IP addresses of the Pods it routes traffic to. By examining the endpoints, you can verify that the correct Pods are registered as endpoints for that service. This check confirms whether the service is configured properly and whether the Pods are healthy and ready to receive traffic.

In contrast, while examining service logs or using `kubectl get services` can provide some information about the service itself, they do not give you direct insight into the state of the endpoints and whether they are properly associated with the service. Monitoring network traffic directly may provide additional diagnostic information, but it does not specifically reveal how the service's routing configuration is set up or whether it is functioning as intended. Therefore, querying the endpoints directly is the most effective method for validating service routing in Kubernetes.
