This book is one of the members of the Cisco Press family of publications that has been
developed to help you prepare yourself for the Cisco Certification examinations. This
book’s specific target is the Support exam (formerly the Cisco Internetwork
Troubleshooting [CIT] Exam). I am a Certified Cisco Systems Instructor, and CIT is one of
the courses that I teach. I started teaching this course in the first quarter of 1999. I have
passed both the old CIT 4.0 and the new Support exams, and I am fully familiar with the
structure, content, and objectives of each of those exams. My students often ask me how I
think the Support exam is different from the old CIT 4.0 exam. My answer is that I did not
notice much change; therefore, any training material that can enhance your knowledge of
the subjects covered in Cisco’s instructor-based CIT course is still very much valid and
useful.
The Support (640-506) exam is one of the four exams you will need to pass to achieve Cisco
Certified Network Professional (CCNP) certification in the Routing and Switching career
track. The other three exams are the Routing (640-503), Switching (640-504), and Remote
Access (640-505) exams. Optionally, you can take one exam that combines these three
exams, Foundation 2.0 (640-509), but you will still need to pass the Support exam
separately to attain CCNP status. Also note that Cisco Certified Network Associate
(CCNA) status is a prerequisite to becoming CCNP certified.
Cisco strongly recommends that you attend its CCNP training courses before taking the
CCNP exams. Table I-1 shows these courses and how they roughly map to the various
exams. Cisco Press publishes coursebooks and Exam Certification Guides like this one to
support your preparation for these exams.

During the time that I was preparing this book, I kept my focus on only one goal: preparing
the readers for the CCNP Support exam. It was difficult at times to keep from adding more
and more extraneous material. My goal is not to teach you, from scratch, the technologies
of Cisco internetworking. Instead, I do assume a CCNA or better level of understanding of
these technologies. From there, I will show you the methodology of support, what tools you
have available, and how to apply them to specific networks. Throughout the book, I present
what I think is absolutely essential for you to know before you attempt the CCNP Support
exam.
This book makes a strong companion to the CIT course and the
Cisco Internetwork
Troubleshooting
coursebook that is published by Cisco Press. While this book presents
some information that is very similar to the course and coursebook, I discuss the material
in a tone and fashion that my experience has shown me an audience responds well to. My
presentation is short, to the point, and very much oriented to exam preparation. Those topics
that I elaborate on are those that I believe, based on my teaching experience with many CIT
students, need rewording or a different angle for best understanding. Of course, this book
also contains additional features designed specifically for test preparation, such as quickreference
Foundation Summary sections and a testing engine on the CD-ROM.
This book’s target audience is primarily those who want a condensed, exam-oriented book
to prepare them for the CCNP Support exam. On the other hand, very often a great portion
of my students who have thoroughly enjoyed the CIT course they have taken express their
desire to have my discussions and presentation in a written and organized format. This book
provides that, too. Indeed, the material adds explanations, output, configuration examples,
and exercises to those you might have seen in CIT training, to help you better understand
the topics being discussed.
I would like to share the following thought with the readers of this book. This book is not
a magic tool that somebody without the proper background can pick up, read, and use to
pass the Support exam. My assumption of the target audience’s background is a more-thanbasic
familiarity with internetworking, routing, switching, and wide-area networking. You
should have at least a CCNA’s knowledge of these subjects. With reference to Cisco’s
training curriculum, this book’s prerequisite, if you will, is similar to the CIT course’s
prerequisite. In other words, I assume that the reader has a good grasp of the material
presented in the ICND (or CRLS/ICRC), BSCN (or ACRC), and BCMSN (or CLSC) Cisco
official training curriculum courses.
