Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ingresscontroller.operator.openshift.io named 'default'
Why this is correct
Modifying the 'default' IngressController object in the operator.openshift.io API group allows scaling and tuning the router.
- ✗
deployment named router-default in openshift-ingress namespace
Why it's wrong here
Directly editing deployments managed by operators is discouraged because the operator will overwrite manual changes.
- ✗
configmap named router-config in openshift-ingress-operator
Why it's wrong here
Router configurations are managed through the IngressController Custom Resource, not this ConfigMap.
- ✗
service named router-default-http in openshift-ingress
Why it's wrong here
Services only manage network ports, not router replicas or deployment parameters.
