Hey, has anyone taken/studied for this exam? I'm taking a Network+ class now in college and the book is like 600 pages long with A LOT of detail. I mean like stating every kind of type of DSL that their is and everything about each type of it. To the last detail. What I'm wondering is how much of this do I have to really know? I know it's good to know all of it... but really I don't see how the A+ exam is 2 exams, and this one is 1 if I have to know ALL of this.
