Query: Very very poor study material for the exam

If you are interested in getting a very very sketchy 'top' level view (and sometimes an incomplete one at that !) of the design practise of Cisco as outlined in their CCDA course objectives, then this book might "just about" meet the specifications.However, if you need to prepare yourself for the CCDA exam well enough to handle the scenarios and the questions, then this book falls way way way short. I am not sure how the folks at Cisco Press could even clear this publications and state that this qualifies as study material for the course ...its THAT insufficent if you know what I mean.If you are going for the exam based on prepartion with this book, you might want to postpone your test date and look at other authors.I would definately NOT recommend this book towards exam prepartion.
