How can you verify that a service is routing traffic to the intended pods?

By checking the service's ClusterIP.

By inspecting the Endpoints object associated with the service.

By looking at the service's nodePort.

You need to expose a service externally, but you have a constraint: you must preserve the client's source IP address. You are using a NodePort service. What should you configure?

Set the service's sessionAffinity to 'ClientIP'.

Set externalTrafficPolicy to 'Local'.

Set externalTrafficPolicy to 'Cluster'.

Use a LoadBalancer service instead.
