Negative Positive
Title: Good idea, but old information.
Review: In trying to follow along with the trainer, a professional CBT on the subject, and the book, I ran into problems with the trainer being set up with Version 5.x commands and the current versions are 11.x so, many of the commands just do not work. It's a great idea if they would just update the software. They should add some sample traffic and do a better job of providing a real-world simulation. It's a good alternative to 'no-hands-on', but it could be better.
