CCNP BSCI Official Exam Certification Guide (4th Edition)

"I just passed the BSCI yesterday and have to tell you this book was helpful but not everything I needed. This book, even though it's in it's 4th addition, has many factual errors and copy editing mistakes. The included Test Simulation propagates those errors. The errata are publish but I spend a lot of time chasing down contradictions and errors... Buy it, but don't count on it.
