Introduction Introduction The Cisco Networking Academy is a comprehensive e-learning program that provides students with Internet technology skills. A Networking Academy delivers web-based content, online assessment, student performance tracking, and hands-on labs to prepare students for industry-standard certifications. The CCNA curriculum includes four courses oriented around the topics on the Cisco Certified Network Associate (CCNA) certification. Accessing the WAN, CCNA Exploration Labs and Study Guideis a supplement to your classroom and laboratory experience with the Cisco Networking Academy. To succeed on the exam and achieve your CCNA certification, you should do everything in your power to arm yourself with a variety of tools and training materials to support your learning efforts. This Labs and Study Guide is just such a collection of tools. Used to its fullest extent, it will help you acquire the knowledge and practice the skills associated with the content area of the CCNA Exploration Accessing the WAN course. Specifically, this book helps you work on these main areas: WAN technology concepts PPP concepts and configuration Frame Relay concepts and configuration Network security threats and mitigation techniques Access control list operation and configuration Broadband services and technologies Network Address Translation concepts and configuration DHCP operation and configuration IPv6 concepts Troubleshooting methodologies and tools Labs and Study Guides similar to this one are also available for the other three courses: Network Fundamentals, CCNA Exploration Labs and Study Guide; Routing Protocols and Concepts, CCNA Exploration Labs and Study Guide; and LAN Switching and Wireless, CCNA Exploration Labs and Study Guide. 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 athttp://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 network 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 Configuration scenarios Concept questions Internet research 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 aPacket 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. xis 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 th
