Anonymous More than 1 year ago
The book is just a good summary of what you need to know, but It doesn't teach you anything about how to configure stuff on IOS and the rest of the concepts are briefly mentioned. So if you are already know it all, it's a great/quick summary, but it's useless if there is anything you need to learn from it! I already had passed an IP networking class in a very respected university before trying CCENT and still had to resort to sources other than this book to learn...
