It is a pretty good representation, but it won't match the real exam 100%. The biggest thing is to be familiar with where to find stuff in the Kubernetes docs. Since the exam is open documentation, if you know where to find stuff you will be able to find info on anything you don't have memorized. It's a good idea to look through the exam objectives and see if you can find the relevant info in the docs for each one. That way you'll have some basic familiarity.
