I got this as part of a CCNA course so that we can practice at home. For most practice labs used in the Sybex Book by Todd Lammle it is quite adequate. However given the expensive price of this it irks me no end that one of the biggest problems is with the help and the autocompletion with tab on the cisco router. Often you press a command such as log? and it will only show a couple of the options or say ambiguous command. I think this a big failing considering that people using it are learners. You definitely need to use a real router as well

I used this lab plus the Sybex CCNA e-Trainer for 3 weeks and passed 640-507 with a 945/1000 score. This lab isn't perfect as it doesn't replicate the entire IOS command set, but it does give you what you need to become a CCNA.

This software sim is great for learning all of those commands that you need. I had trouble using multiple session Telnet, however, that is not a big deal. However, the big deal is on the exam when you are given a simulation that has routers that have been set up, but do not work. Yes, you have to diagnose whats wrong with your network. To my knowledge only authorized Cisco learning centers are equipped to teach this. Just do not expect this software to cover all the sims on the test. Check out the Cicso eSim, it offers alot more than this one.
