I have a friend who waited too long and now has to take one of the newer exams

Anyway I have no experience with them, but it seems there is some kind of hands on component now. What can you guys tell me? I think he told me about some things with powershell, and other stuff I don't think was in my exam last time.
How much effort should be spent on book vs hands on? And what is a good lab to have if someone doesn't have the official lab?
Thanks in advance!
