Title: Good book for 642-501
Review: This is the first book I started off with for preparing for 642-501(Securing IOS Networks ) exam and I liked this book very much.This is the only book I could find the information about SDM, which is a topic in the exam. Some times you feel like the text is too verbose, but this does not take the gist away from the topic at hand. Only downside of this book is, it does not come with a CD. If they come up with a companion CD with some sample questions, I think you can pass the exam with this single book.
Is the review positive or negative?
