Dear Community. As part of the DO316 4.16 Chapter 10: Comprehensive Review
I could not see lab COURSE for review-cr4 and review-cr5
You may wish to open a support ticket in the Red Hat Training Portal: https://rol.redhat.com/ The "Support" button is at the very top left hand corner and clicking it should expand a form to the right where you can fill in the details and submit a ticket.
That said, note that an updated version of the DO316 course v4.18 "Red Hat OpenShift Virtualization Administration Rapid Track" course is available: https://rol.redhat.com/rol/app/courses/do316-4.18/ The updated v4.18 version of RHOV includes a dedicated "Virtualization" perspective in the RHOCP web console and various quality-of-life improvements catering to users migrating from other hypervisors such as VMware.
