input with options: Title: read this book Review: It's unfortunate that James Frey's debut novel received so much press so long before his book actually hit the shelves. Many people seem to be judging his work-or more accurately, him-based on a few interviews they've read. Why not read the book and decide for yourself? I promise you, it will be well worth your time, which is more than I can say about some of the articles written about him. Is this product review negative?
output: No

input with options: Title: The ultimate NOC Survival Guide!! Better than the first one! Review: Excellent! Purchased it based on the reviews of the first one and, sufficed it to say, it's better than I expected... True, many of the concepts, configurations & TS methods covered in this book were short & to the point w/o burning too much candle on it; but then again, you shouldn't be reading this if you're not already experienced in internetworking or have a clue on fundamentals... NOC engineers/Network admins: Get this book! Major headache eliminator.... Beginners/"shortcut" hunters: Do yourself a favor & buy a basic guide on Cisco routing first before tackling this one (at least that'll eliminate blaming the book because you couldn't grasp the information contained in it).
