Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Describing the ingresscontroller custom resource in the openshift-ingress-operator namespace reveals reconciliation status errors and validation messages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
oc logs -n openshift-ingress deployment/router-default
Why it's wrong here
Router pods cannot start if validation fails, so their logs will not reflect the operator's CR validation error.
- ✗
oc adm inspect router
Why it's wrong here
oc adm inspect collects cluster logs but does not validate operator schema errors interactively.
- ✗
oc get validatingwebhookconfigurations
Why it's wrong here
While webhooks enforce admission, operator reconciliation errors are stored in the operator CR status, not webhook objects.
- ✓
oc describe ingresscontroller default -n openshift-ingress-operator
Why this is correct
Describing the IngressController custom resource displays detailed operator status conditions and error reasons.
