Neo, By Neo "Morpheus" (Port Charlotte, FL USA) - See all my reviews
This review is from: CCNP ONT Official Exam Certification Guide (Hardcover)
Minimal Fluff. Clear and concise explanations, very good examples. I used the book to study for the ONT exam, which I successfully completed. There are a few methods that are covered and all I was interested in was, what the methods are, why were they developed, when to use them and how. The book proved to be right on the money. I would recommend this book as a Reference source as well.Personally, I wish they would write technical books in this fashion using the following headings: Method, Why developed/Issues addressed, When to use and How. Just forget all the fluff and get down to the Nitty Gritty.

I used this to book as my major source of information for the exam. I passed with relative confidence doing so. However, you definitely need to know all the information contained within. It's knowing the little details that often decide what the correct answer is. Don't let the size of the book fool you, there is a lot of information contained within. I would still supplement this with the chapter from the BCMSN Exam Certification guide on the WLC and Unified Wireless, more info on WMM from Wi-Fi Alliance site, and some further review on all the options you can do with class and policy maps (if you don't work with them normally). I also watched the CBT Nuggets videos. While great for showing some real-life CLI configs, they lack a ton of information and those details I mentioned earlier to pass the exam. They won't really help you pass the exam. Same goes for the Bryant Advantage study guides which are just too lacking to use for anything but supplemental information. While...
