Well, the days of using the Boson network simulator for your CCNA studies is over (thankfully!). I have used simulators quite often over the years and have had mixed feelings about them. I think the new CCENT network simulator will surprise a lot of people out there with mixed feelings about using simulators. You have to remember that simulators are scripted and pretty linear so don’t expect to be able to configure your own network scenarios and use any IOS command you can think of. The purpose of this simulator is to provide hands-on practice being able to master all the objectives on the CCNA exam. It simply runs from your PC once installed.
