Audience for This Book
This book's main audience is anyone taking the CCNA Exploration Accessing the WAN course of the Cisco Networking Academy curriculum. Many Academies use this book as a required tool in the course, and other Academies recommend the Labs and Study Guides as an additional source of study and practice materials.
Goals and Methods
The most important goal of this book is to help you pass the CCNA exam (640-802). Passing this foundation exam means that you not only have the required knowledge of the technologies covered by the exam, but that you can plan, design, implement, operate, and troubleshoot these technologies. In other words, these exams are rigorously application-based. You can view the exam topics any time at http://www.cisco.com/go/certifications. The topics are divided into eight categories:
Describe how a network works
Configure, verify, and troubleshoot a switch with VLANs and interswitch communications
-Implement an IP addressing scheme and IP Services to meet network requirements in a
medium-size Enterprise branch office network
Configure, verify, and troubleshoot basic router operation and routing on Cisco devices
Explain and select the appropriate administrative tasks required for a WLAN
Identify security threats to a network, and describe general methods to mitigate those threats
Implement, verify, and troubleshoot NAT and ACLs in a medium-size Enterprise branch office
Implement and verify WAN links
The Accessing the WAN course focuses on the third, fifth, sixth, seventh, and eighth topics.
The Study Guide portion of each chapter offers exercises that help you learn the Accessing the WAN concepts as well as the configurations 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
Skill-building activities and scenarios
In the configuration chapters, you'll find many Packet Tracer Activities that work with the Cisco Packet Tracer tool. Packet Tracer allows you to create networks, visualize how packets flow in the network, and use basic testing tools to determine whether the network would work. When you see this icon, you can use Packet Tracer with the listed file to perform a task suggested in this book. The activity files are available on this book's CD-ROM; Packet Tracer software, however, is available through the Academy Connection website. Ask your instructor for access to Packet Tracer.
The Labs and Activities portion of each chapter includes all the online Curriculum Labs, some additional supplemental labs that you can perform with Packet Tracer, and a Packet Tracer Skills Integration Challenge Activity. The Curriculum Labs are divided into three categories:
Basic: The Basic Labs are procedural in nature and assume that you have no experience configuring the technologies that are the topic of the lab.
Challenge: The Challenge Labs cover implementations and assume that you have a firm-enough grasp on the technologies to "go it alone." These labs often give you only 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 chapter text, activities, and Basic Lab to successfully complete the Challenge Lab. Avoid the temptation to work through the Challenge Lab by flipping back through the Basic Lab when you are unsure of a command. Do not try to short-circuit your CCNA training. You need a deep understanding of CCNA knowledge and skills to ultimately be successful on the CCNA exam.
Troubleshooting: The Troubleshooting Labs ask you to fix a broken network. These labs include corrupted scripts that you purposely load onto the routers. Then you use troubleshooting techniques to isolate problems and implement the solution. By the end of the lab, you should have a functional network with full end-to-end connectivity.
Most of the Hands-on Labs include Packet Tracer Companion Activities, in which you can use Packet Tracer to complete a simulation of the lab.
Each chapter ends with a Packet Tracer Skills Integration Challenge. These activities require you to pull together several skills learned from the chapter—as well as previous chapters and courses—to successfully complete one comprehensive exercise.
A Word About Packet Tracer
Packet Tracer is a self-paced, visual, interactive teaching and learning tool developed by Cisco. Lab activities are an important part of networking education. However, lab equipment can be a scarce resource. Packet Tracer provides a visual simulation of equipment and network processes to offset the challenge of limited equipment. Students can spend as much time as they like completing standard lab exercises through Packet Tracer, and they have the option to work from home. Although Packet Tracer is not a substitute for real equipment, it allows students to practice using a command-line interface. This "e-doing" capability is a fundamental component of learning how to configure routers and switches from the command line.
Packet Tracer version 4.x is available only to Cisco Networking Academies through the Academy Connection website.
How This Book Is Organized
Because the content of this book and the online curriculum is sequential, you should work through this book in order, beginning with Chapter 1.
The book covers the major topic headings in the same sequence as the online curriculum for the CCNA Exploration Accessing the WAN course. This book has eight chapters with the same numbers and names as the online course chapters.
If necessary, a chapter uses a single topology for the exercises in the Study Guide portion. This single topology allows for better continuity and easier understanding of switching commands, operations, and outputs. However, the topology is different from the one used in the online curriculum and the Companion Guide. A different topology affords you the opportunity to practice your knowledge and skills without just simply recording the information you find in the text.
Chapter 1, "Introduction to WANs": The exercises in the Study Guide portion of this chapter focus on LAN design concepts, including vocabulary and the three-layer hierarchical model. The Lab portion of the chapter includes a Basic Lab, a Challenge Lab, a Troubleshooting Lab, and a Packet Tracer Skills Integration Challenge activity.
Chapter 2, "PPP": The exercises in the first part of this chapter help you understand basic Ethernet and switching concepts, including building the MAC address table and collision and broadcast domains. Then the Packet Tracer exercises cover, in detail, how to configure a switch, including basic switch management and configuring switch security. The Lab portion of the chapter includes two Basic Labs, a Challenge Lab, and a Packet Tracer Skills Integration Challenge activity.
Chapter 3, "Frame Relay": The exercises in the first portion of this chapter focus on the concepts of VLANs, including benefits of VLANs and types of VLANs. The exercises then cover VLAN trunking concepts before moving into a section devoted to a VLAN and trunk configuration Packet Tracer exercise. The Lab portion of the chapter includes a Basic Lab, a Challenge Lab, a Troubleshooting Lab, and a Packet Tracer Skills Integration Challenge activity.
