While you do get access to a "virtual rack" of equipment to use as a part of the course, having access to physical equipment will help fill in the blanks that a simulator will probably leave for you. Paul gives you some good suggestions on what hardware that you should consider working with. For those working through Paul's program, you will find others to bounce idea off of in addition to Paul by going to. You get two substantial binders from Paul that will take you through a building block process for building the knowledge you dont have and expanding on the knowledge that you do have. You learn how to do the bit level math that you need to know to really understand what you are doing but more important, how to quickly do the calculations for the test using his "Super Subnetting Chart."

If money is really tight, you can buy a couple of 2501s with a serial crossover cable. While it is possible to use simulators that get you the experience of working with the equipment, certain things such as upgrading firmware and connecting cables just cant be done with simulators. The first is getting experience with the hardware itself. There are two main areas that you need to think about. ![]()
