I had a question on an EX280 exam that requested to set a self-signed certificate for an app, specifying only the 'subj' field for the cert. No CA cert, no CA key was given. For this I presume it was asking to create a passthrough route.
How to resolve this? Only thing I can imagine is extracting some internal OpenShift CA and Key to subsequently sign via 'openssl x509' command but don't know how (if possible) to do this.
Since we cannot answer questions regarding exam content directly, I can only refer to this posting and the according thread, where you should find all information needed:
