CCDA examanination tests you on a wide range of topics and you need to have a good grasp of voice & video, switch & routing, wireless, and security as well as design methodology. I have read the two offical Cisco press books but this presents the information in a clear concise manner which aids learning of less familiar subjects. This book fills a void in the market for quality material on a complex exam.
Having used this book as the main source of my studies, I passed the design exam :)
