Where to begin?,
This review is from: CCNP Security Secure 642-637 Official Cert Guide (Hardcover)
I knew this was going to be a rough read when the very first sentence of Chapter 1 was a grammatical nightmare, but since it's technical material I set aside my reservations about the quality of the writing and focussed on the technical merits. Sadly, only disappointment lay in that direction as well. Serious and obvious technical errors abound - as an example, the most recent one I read showed a sample configuration which included an access list where the author mistakenly entered a subnet mask rather than a wildcard mask. While the statement is still technically syntactically valid, it would have a very different effect than was described - a clear indication that neither of the authors nor either of the technical reviewers bothered doing anything as basic as actually *testing* the configurations they wrote up prior to publishing. This one is merely an example - additional technical errors can be found in multiple places.Overall, the book reads as if written by... Read more

Should be much better, By
This review is from: CCNP Security Secure 642-637 Official Cert Guide (Hardcover)
Like for first reviewer, I am currently using this book towards by certification exam and find it poorly written and mistake-prone. To properly understand the subject matter and be certain of the accuracy of the information being read, you will have to constantly research other information on the internet. I find myself regularly scouring the Cisco.com support pages for additional information, to explain topics better or deal with mistakes in the book. Should be of a much higher standard.*** I have since finished this book and while I was hopeful that it would improve as I continued sadly it did not. Without even attempting to find mistakes in the book I was constantly presented with them. While most were typos there were still many technical errors. The amount of typos, though in themselves relatively easy to correct, only made me less confident in the quality of technical material I was reading. One of the most embarrassing errors I found was when doing the "Do I Know... Read more

A Poor Work, By
This review is from: CCNP Security Secure 642-637 Official Cert Guide (Hardcover)
I am currently using this book to prepare for the 642-637 exam. I think this book was poorly written. There are so many errors, both technical an non-technical. There are flaws that should not pass through a technical review and remain uncorrected. Yet they did. This makes one to wonder as to what the technical review is all about then. I'll advise anyone who is using this book as an exam prep tool to also use Cisco's documentation on its website. The authors and technical reviewer need to revisit this material.
