I took my certification virtually. They were pretty strict. It's best if you're in a room where you can clearly show that the walls and other surfaces are bare and clean. Even my water bottle had to be transparent. They do not let you plug in any external monitors either. And you do need to be on camera the whole time.
My coworker tried to do it at work, and he failed to connect since our work has added security on the internet connection, so be aware of that kind of thing as well, like maybe having to disconnect from VPN, etc.
