A computer network connects two or more devices together to share a nearly limitless range of information and services, including: Documents Email and messaging Websites Databases Music Printers and faxes Telephony and videoconferencing Protocols are rules that govern how devices communicate and share information across a network.Examples of protocols include: IP

Internet Protocol HTTP

- Hyper Text Transfer Protocol SMTP

Simple Mail Transfer Protocol Multiple protocols often work together to facilitate end-to-end network communication, forming protocol suites or stacks.Protocols are covered in great detail in other guides.Network reference models were developed to allow products from different manufacturers to interoperate on a network.

A network reference model serves as a blueprint, detailing standards for how protocol communication should occur.The Open Systems Interconnect (OSI) and Department of Defense (DoD) models are the most widely recognized reference models.Both are covered in great detail in another guide.CCNA Study Guide v2.52

The two most common categories of networks are: LANs (Local Area Networks)WANs (Wide Area Networks) LAN is generallya high-speed network that covers a small geographic area, usually contained within a single building or campus.A LAN is usually under the administrative control of a single organization.Ethernet is the most common LAN technology.A WAN can be defined one of two ways.The book definition of a WAN is a network that spans large geographica

is a supplement to your classroom Networking Academy Program.Specifically, this book covers the second of four courses.To be successful on the exam and achieve hing possible to arm yourself with a variety of tools and training materials to on these main areas of CCNA 2: Implementing basic security with access control lists The most important goal of this book is to help you prepare for either the CCNA exam (640-801) or the INTRO exam (640-821).

Whether you are studying for the full exam or the first part of your CCNA, passing either of these exams means that you not only have the required knowledge of the technologies covered by the exam, but that you can also plan, design, implement, operate, and troubleshoot these technologies.In other words, these exams are rigorously application based.In fact, if you view the main objectives for the CCNA exam at , you can see the following Implementation & Operation implement, operate, and troubleshoot networks without first fully grasping the technology.

So you must devote large amounts of time and effort in the Study Guide section of each chapter, learning the concepts and theories before applying them in the Page 2 of 13 Routers and Routing Basics CCNA 2 Labs and Study Guide

ISBN 1-58713-167-6 configurations that are crucial to your success as a CCNA exam candidate.Each chapter is slightly different and includes some or all of the following types of exercises: Vocabulary Matching and Completion The Lab Exercise sections include a Command Reference table, all the online Curriculum Labs, and brand new Comprehensive Labs and Challenge Labs.

The Curriculum Labs typically walk you through the configuration tasks step by step.

The Comprehensive Labs include many, if not all, of the configuration tasks of the Curriculum Labs without actually providing you with the commands.

The Challenge Labs take this a step further, often only giving you a general requirement that you must implement fully without the details of each small step.In other words, you must use the knowledge and skills you gained in the Curriculum Labs to successfully complete the Comprehensive and Challenge Labs.

In fact, you should not attempt the Comprehensive or Challenge labs until you have worked through all the Study Guide activities and the Curriculum Labs.Avoid the temptation to work through the Comprehensive and Challenge Labs by flipping back through the Curriculum Labs when you are not sure of a command.Do not knowledge and skills to ultimately be successful on the CCNA exam.

How This Book Is Organized covering the topic of WANs, this chapter delves into the internal and external components of routers.Understanding how a router works and how you connect to a router are important concepts and skills you need throughout the rest of your CCNA studies

Do not try to short-circuit your CCNA training.Study the chapter's topics until you can do the Comprehensive and Challenge Labs without any help.You need a deep understanding of CCNA knowledge and skills to ultimately be successful on the CCNA exam.How This Book Is Organized Chapters 1, 2, and 3 cover Intermediate Routing and focus on VLSM and routing three different CCNA 3 Skills-Based Assessment practice labs.
