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.
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.
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).
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.
Be warned that this test is harder than the MCSE or CNE exams. However, it has some overlapping material with the
Networking Technologies exam by Novell or the Networking Essentials exam by Microsoft. I would highly recommend that
you take these exams before even considering the CCNA exam. If you do not have a solid understanding of the essentials
of networking, you will be throwing away $100.

Please do not consider the answers to these questions as gospel. I’m not guaranteeing
that everything is correct as a lot of these questions were collected from a variety of
sources. I’ve added some of my own to fill in some gaps that I thought might be
covered on the exam.
Your role as a Cisco Certified Design Associate is to be a network design consultant. You will act like
an architect, building comprehensive designs that solve your customer's internetworking problems and
provide the required functionality, performance, and scalability. In the same way that an architect
designs a building or house for a client, you will develop blueprints for an overall internetwork
design, as well as components plans for various pieces of the internetwork.
