Welcome to the exciting world of Cisco certification! You have picked up this book because
you want something better; namely, a better job with more satisfaction. Rest assured that you
have made a good decision. Cisco certification can help you get your first networking job, or
more money and a promotion if you are already in the field.
Cisco certification can also improve your understanding of the internetworking of more
than just Cisco products: You will develop a complete understanding of networking and how
different network topologies work together to form a network.
This Study Guide is targeted specifically at people who wish to take the Cisco CCNP 640-606 – Support
(CIT) exam. This information in this Study Guide is specific to the exam. It is not a complete reference work.
Although our Study Guides are aimed at new comers to the world of IT, the concepts dealt with in this Study
Guide are complex and require an understanding of material provided for the Cisco Certified Network
Associate (CCNA) exam 640-607. Knowledge of CompTIA’s A+ course would also be advantageous but is
not a requirement....
Cisco certification can also improve your understanding of the internet-
working of more than just Cisco products: You will develop a complete
understanding of networking and how different network topologies work
together to form a network. This is beneficial to every networking job and is
the reason Cisco certification is in such high demand, even at companies with
few Cisco devices.
This product will provide you questions and answers along with detailed explanations carefully compiled and
written by our experts. Try to understand the concepts behind the questions instead of just cramming the

important to have at least read the Sybex CCNA: Cisco Certified Network
Associate Study Guide, as well as the Sybex CCNP: Routing Study Guide,
CCNP: Support Study Guide, CCNP: Switching Study Guide, and CCNP:
Remote Access Study Guide. You should have also considered completing
your CCNP (although that is not a requirement to obtain your CCIE).
Cisco’s Cisco Certified Network Administrator (CCNA) certification provides a way to distin-
guish those brilliant and talented enough to become Cisco administrators from those who just
might be, umm—well, better suited to another occupation. It’s basically Cisco’s version of sep-
arating the wheat from the chaff. The main reason that it’s a really good thing to be the proud
possessor of Cisco’s certifications is that they give you a serious edge over the poor, wretched,
unfortunate, and noncertified masses.
One of the keys to understanding Cisco is the OSI model. The OSI model permits
people to understand how internetwork works and it serves as a guideline or framework
for creating and implementing network standards, devices, and internetworking schemes.
Some of the advantages of the OSI model include:
• It allows for the breaking down of complex operation into simple elements;
• Enables engineers to specialize the design and development of modular elements;
• It provides standards for plug and play and multivendor integration....
Cisco Certified Network Associate (CCNA®) validates the ability to install, configure, operate, and troubleshoot medium-size route and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills.
Helps students prepare for the CCNA (Cisco Certified Network Associate) exam, one of the most popular entry-level certifications for networking professionals and one that often translates into a salary increase

Explanation: Point-to-Point Protocol (PPP) provides router-to-router and host-network connections over
synchronous and asynchronous circuits. PPP was designed to work with several network layer protocols,
including IP and IPX. It also has built in security features such PAP (Password Authentication Protocol) and
CHAP (Challenged Handshake Authentication Protocol).
Welcome to the world of Cisco Certified Network Associate (CCNA) Wireless! As technology
continues to evolve, wireless technologies are finding their way to the forefront.
This clearly indicates the progression from a fixed wired type of connectivity to a more
fluid, mobile workforce that can work when, where, and how they want. Regardless of
your background, one of the primary goals of the new CCNA Wireless certification is to
introduce you to the Cisco Unified Wireless Network (CUWN).
This book is intended to start you out on an exciting new path toward obtaining your CCNA certification. It reaches beyond
popular certifications like the MCSE and CNE to provide you with an indispensable factor in understanding today¡¯s
network¡ªinsight into the Cisco world of internetworking and network design.
If you¡¯ve purchased this book, you are probably chasing one of the Cisco professional certifications: CCNA/CCNP,
CCDA/CCDP, CCIP, or CCIE. All of these are great goals, and they are also great career builders.
