CCSP SNRS Exam Certification Guide (ISBN 1587201534)

Disappointing:
I've purchased numerous Cisco Press certification books over the years. This one is very disappointing from the editing stand-point. Command formats are listed in the text throughout the book and when the command is used in a configuration example, it differs from the format in the text. You are left to decide if there is a hyphen between words or a space. I found that I needed to consult Cisco's web page very often for clarification. This should not be required when you purchase a book that is supposed to prepare you for an exam. You're left feeling uncertain if what you've learned is correct and that's not what you want before an exam. The test engine that is included has even more errors than the book. The "correct" answers to numerous questions are blatantly wrong. There were several questions where you are told to make 3 selections and the test engine is expecting 4. Some questions wouldn't accept any answer, so the correct answer was no answer. Also, you are asked to determine the results of a configuration, but no configuration is displayed. Very disappointing. I haven't taken the exam yet, so I don't know if this book was worth the price/effort.

Exam Retired, do not buy this book:
While I'd rate the book a five star if it was still useful, the exam is now retired. There should be another book coming out for the new version of the exam. Check at Cisco Press, or wait until Amazon gets the new books. Purchasing this book would be a waste of money. While most of the material is the same, there are significant new areas that are just not covered in this version that you need to know for the new test.

Not the easiest exam, but a must have book for me:
This one of those strange exams, well thats my opinion anyway, the subject is a bit all over the place, and for me i found i really did need this book for coverage. I don't know if i will use it as a reference in the future, but it did succeed in helping me gain my pass.

Great exam book 642-502!!!:
Best reference for the exam. It covered everything necessary for the SNRS exam. I wish all the books gave me as much information as this for the specific exam. Nice job!

A Must Have!:
I'm an old CCIE/CNE/CISSP, and I have purchased dozens of technical study guides over the years. I believe this is one of the better exam certification guides. Additionally, it contains real world examples and explanations. I refer to this book often in my day-to-day operations. If you want the best study guide out there for the SNRS exam, then you need not look any further. Good luck!
