To Our Valued Readers:
As internetworking technologies continue to pervade nearly every aspect of public and private
industry worldwide, the demand grows for individuals who can demonstrate they possess the
skills needed to manage these technologies. Recognizing this need, Juniper Networks—the lead-
ing provider of Internet infrastructure solutions that enable ISPs and other telecommunications
companies to meet the demands of Internet growth—recently restructured its certification
program to provide a clear path for the acquisition of these skills. Sybex is proud to have part-
nered with the Juniper Networks and worked closely with members of the Juniper Networks
Technical Certification Program to develop this Official Study Guide for the Juniper Networks
Certified Internetworking Associate certification.
Just as Juniper Networks is committed to establishing measurable standards for certifying those
professionals who work in the cutting-edge field of internetworking, Sybex is committed to
providing those professionals with the means of acquiring the skills and knowledge they need
to meet those standards. It has long been Sybex’s desire to help individuals acquire the technical
knowledge and skills necessary to excel in the IT industry.
The authors and editors have worked hard to ensure that this Official Juniper Networks Study
Guide is comprehensive, in-depth, and pedagogically sound. We’re confident that this book
will exceed the demanding standards of the certification marketplace and help you, the
Juniper Networks certification candidate, succeed in your endeavors.
Good luck in pursuit of your Juniper Networks certification!
