For years now, data networks have become increasingly important. At first,networks were just a large corporate phenomenon. Now, almost any business
with more than a few computers or more than one location has a data network.
And now, with the growth of the Internet, many people’s home computers
are often connected to a network. As data networks grow in size and
importance, there must be a corresponding growth of people required to
design, build, and maintain them.
Cisco invented the router and has been selling networking products since
1986. Since then, the company has maintained a definitive lead in the data
networking marketplace. Some people estimate that 85% of routers and
switches are Cisco products. Regardless of the exact number (which is hard to
definitively prove), Cisco is and probably will be a major player for a long
time to come.
So, two factors should reinforce your decision to obtain Cisco certification:
The continual rise in the importance of data networks
Cisco’s market leadership in much of this market
So, if you are an entrepreneurial individual who is interested in computers,
you’ll see these two factors and notice a growing employment market for people
trained in Cisco networking products. Cisco certainly saw this, and that
is why Cisco developed its certification series.
This book is written for intermediate to advanced network engineers who
have at least some hands-on experience. Some topics, even some whole chapters,
assume you have a certain familiarity with networks. We wrote this book
like this for two reasons. First, the CCIE is one of the most advanced professional certifications
in the world. It certainly is the most advanced network-related technical certification.
It is unrealistic for an average person to be able to read a single book and be able
to pass the CCIE Written Exam. Also, the amount of material that would be required to
take a complete novice to the level of knowledge required to pass the CCIE Written
Exam would not fit within the covers of a single book.
We recommend at least two years of solid hands-on data networking professional experience
(that is, not just tech college, college, or university classes) before seriously pursuing
the CCIE certification. You might be able to pass the written exam, but you’d have to
take the lab exam within a year, and classroom experience is just not enough to offer you
a reasonable chance of success.
However, if you have two years of experience, we strongly encourage you to take this big
step in your career. CCIEs are in extremely high demand. Not only is a CCIE a great
thing to put on your résumé, but it will help you immensely when it comes time to discuss
your salary and benefits package!
