Query: RTFM instead of this book

stay away from this book if you want to pass the CSPFA. it doesn't map to the exam objectives, Cisco is aware of that and freely admits to it. I also have on good authority that the book was rushed to press so it wasn't reviewed very carefully. The exams on the included cd are pathetic. Save your money, read the documentation for the PIX.
