Отрывок из книги

There are many people who work to put a book together, and as an author, I dedicated an enormous amount of time to write this book, but it would have never been published without the dedicated, hard work of many other people.

Kenyon Brown, my acquisitions editor, is instrumental to my success in the world of Cisco certification. Ken, I look forward to our continued progress together in both the print and video markets! My technical editor, Todd Montgomery, was absolutely amazing to work with and he was always there to check my work and make suggestions. Thank you! Also, I've worked with Kim Wimpsett, the development editor, for years now and she coordinated all the pages you hold in your hands as they flew from thoughts in my head to the production process.

Chapter 21: Wide Area Networks This is the longest, and last, chapter in the book. It covers multiple protocols in depth, especially HDLC, PPP, and Frame Relay, along with a discussion on many other technologies. Good troubleshooting examples are provided in the PPP and Frame Relay configuration sections, and these cannot be skipped! Hands-on labs meant to focus squarely on the objectives are included at the end of the chapter, as well as a written lab and challenging review questions.

Chapter 22: Evolution of Intelligent Networks I saved the hardest chapter for last. What makes this chapter challenging is that there is no configuration section to you really need to dive deep into the cloud, APIC-EM and QoS sections with an open and ready mind. I stuck as close to the objectives as possible in order to help you ace the exam. The written lab and review questions are spot on for the objectives.
