Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
Custom route certificates are managed via secrets referenced in the IngressController resource.

In the IngressController resource named 'default' in openshift-ingress-operator
Why this is correct
The defaultCertificate reference in the IngressController spec defines the wildcard certificate used by the router.
