A platform team enables the ingress controller that ships with Cilium and creates an Ingress object. Which field ties that object to Cilium's controller?

選択肢

1. The ingressClassName field set to cilium.
2. The loadBalancerClass field on the Service, which the controller reads to decide whether it should claim the object.
3. An annotation on the namespace that names the controller because the class name is only advisory and the actual selection is performed by whichever controller watches that namespace first.
4. The gatewayClassName field, which is the standard way an Ingress object names its controller.
