Hello Frank
As far as I know, there is currently no way to lab up VSS on any emulator. In order to have hands-on experience, you must have access to such devices. However, all is not lost! On the one hand VSS is not that complicated so thoroughly reading up on it should be enough for any certification needs, and secondly, there are a lot of videos available where others have implemented VSS that you can follow along first hand.
I know, I know, there’s nothing like labbing something up to fully understand it. Unfortunately, because VSS is so hardware dependant, it’s not something that can be effectively emulated. It’s expected to be a very small part of the certification exam, so not to worry.
I hope this has been helpful!
