CCNP Security Cisco Secure Firewall and Intrusion Prevention System Official Cert Guide

Just finished (failing) the exam, and this book is lacking core areas of concentration. I won't go into "what" areas are missing that the exam hit hard for NDA purposes, but I will say that from scouring forums, most people who passed first try did not use this book as a main source. That honor goes to Todd Llammle's two book set. I know that other folks at my work who used this as a source struggled. Very dry style as compared to Lammle, and as I said, missing MAJOR hot topics that you'll see on the exam. In retrospect, I wish I had used Lammle's books as a primary source, especially since they are free as part of Kindle Unlimited.
