There are countless resources just a quick search a way that will list all the things you should study in preparation for a particular exam. Likely you will find Microsoft Virtual Academy courses, TechNet/MSDN articles, blog posts, books, practice exams and much more. Let me be clear, those are all super useful.
However, I will share how I passed the exams, which is not to say how you can or will, but if you are like me (just a bit?), maybe this will be helpful.
