I hope I find you well.
I would like to advise you to progress through the path of CCSA->CCSE->CCSM (R80.20) for which you will practice virtual systems, multi-domain (CCSM) as it's part of our core product, alongside with advanced diagnostics and troubleshooting practices.
R77 MDM/VSX in our training portal is indeed a legacy course and targeted to specific region at Europe (Will be removed from our site by June 2019).
For further training advisory you can contact me at firstname.lastname@example.org or call me +1-415-2513078
