A while back, I was putting together a study guide with Charles Pluta for 70-414. Well, we ran out of time. But, there was some pretty good content. I spent quite a bit of time on a Visio diagram for ACS. It is technically a "one-pager", which is really my favorite length for a topic that you are studying to prep for the exam. So, here it is in .png format.
I'm making the original Visio diagram available for download too. You can find that at the following URL:
Enjoy and good luck!
