xxxSwitching,Routing,andWirelessEssentialsLabsandStudyGuide(CCNAv7)IntroductionThis book supports instructors and students in Cisco Networking Academy, an IT skills andcareer building program for learning institutions and individuals worldwide. Cisco NetworkingAcademy provides a variety of curricula choices, including the very popular Cisco CertifiedNetwork Associate (CCNA) curriculum. It includes three courses oriented around the topics ofCCNA certifications.Switching, Routing, and Wireless Essentials Labs and Study Guide is a supplement to yourclassroom and laboratory experience with the Cisco Networking Academy. To be successfulon the exam and achieve your CCNA certification, you should do everything in your power toarm yourself with a variety of tools and training materials to support your learning efforts. Thisbook provides just such a collection of tools. Used to its fullest extent, it will help you gainthe knowledge as well as practice the skills associated with the content area of the Switching,Routing, and Wireless Essentials v7 course. Specifically, this book will help you work on thesemain areas:■■Configure devices using security best practices.■■Explain how Layer 2 switches forward data.■■Implement VLANs and trunking in a switched network.■■Troubleshoot inter-VLAN routing on Layer 3 devices.■■Explain how STP enables redundancy in a Layer 2 network.■■Troubleshoot EtherChannel on switched links.■■Implement DHCPv4 to operate across multiple LANs.■■Configure dynamic address allocation in IPv6 networks.■■Explain how FHRPs provide default gateway services in a redundant network.■■Explain how vulnerabilities compromise LAN security.■■Implement switch security to mitigate LAN attacks.■■Explain how WLANs enable network connectivity.■■Implement a WLAN using a wireless router and WLC.■■Explain how routers use information in packets to make forwarding decisions.■■Configure IPv4 and IPv6 static routes.■■Troubleshoot static and default route configurations.Labs and Study Guides similar to this one are also available for the other two courses:Introduction to Networks Labs and Study Guide and Enterprise Networking, Security, andAutomation Labs and Study Guide.Who Should Read This BookThis book’s main audience is anyone taking the Switching, Routing, and Wireless Essentialscourse of the Cisco Networking Academy curriculum. Many Academies use this Labs andStudy Guide as a required tool in the course, whereas other Academies recommend the Labsand Study Guide as an additional resource to prepare for class exams and the CCNA certi-fication. The secondary audience for this book is people taking CCNA-related classes from

professional training organizations. This book can also be used for college- and university-levelnetworking courses, as well as anyone wanting to gain a detailed understanding of routing.However, the reader should know that the content of this book tightly aligns with the CiscoNetworking Academy course. It may not be possible to complete some of the Study Guidesections and Labs without access to the online course. Fortunately, you can purchase theSwitching, Routing, and Wireless Essentials v7.0 Companion Guide (ISBN: 9780136729358).Goals and MethodsThe most important goal of this book is to help you pass the 200-301 Cisco Certified NetworkAssociate exam, which is associated with the Cisco Certified Network Associate (CCNA)certification. Passing the CCNA exam shows that you have the knowledge and skills requiredto manage a small enterprise network. You can view the detailed exam topics online, at http://learningnetwork.cisco.com. They are divided into six broad categories:■■Network Fundamentals■■Network Access■■IP Connectivity■■IP Services■■Security Fundamentals■■Automation and ProgrammabilityThe Introduction to Networks v7 course covers introductory material in the first fivebullets. The next two courses, Switching, Routing, and Wireless Essentials v7 and EnterpriseNetworking, Security, and Automation v7, cover the material in more detail. Each chapter ofthis book is divided into a “Study Guide” section followed by a “Labs and Activities” section.The “Study Guide” section offers exercises that help you learn the concepts, configurations,and troubleshooting skills crucial to your success as a CCNA exam candidate. Each chapter isslightly different and includes some or all of the following types of exercises:■■Concept question exercises■■Skill-building activities and scenarios■■Configuration scenarios■■Packet Tracer exercises■■Troubleshooting scenariosThe “Labs and Activities” sections include all the online course labs and Packet Tracer activityinstructions. In some chapters, this section begins with a Command Reference that you willcomplete to show that you understand all the commands introduced in the chapter.Packet Tracer and Companion WebsiteThis book includes the instructions for all the Packet Tracer activities in the online course. Youneed to be enrolled in the Introduction to Networks v7 course to access these Packet Tracer files.Nine Packet Tracer activities have been created exclusively for this book. You can access theseunique Packet Tracer files at this book’s companion website.Introductionxxxi

It includes initial switch and router configuration,switch port configuration, remote access configuration, and verification of connectivitybetween two networks.■■Chapter 2, “Switching Concepts”:This chapter explains how switches forward data.Itincludes frame forwarding methods and collision and broadcast domain comparison.■■Chapter 3, “VLANs”:This chapter explains how to implement VLANs and trunk-ing in a switched network. It includes an explanation of the purpose of VLANs, howVLANs forward frames in a multi-switched environment, VLAN port assignments, trunkconfiguration, and DTP configuration.■■Chapter 4, “Inter-VLAN Routing”:This chapter explains how to implement inter-VLANrouting. It includes a description of inter-VLAN routing options, router-on-a-stickconfiguration, Layer 3 switch inter-VLAN routing, and troubleshooting of commoninter-VLAN routing configuration issues.■■Chapter 5, “STP Concepts”:This chapter explains how STP enables redundancy in aLayer 3 network. It includes an explanation of common problems in redundant Layer 2networks, STP operation, and Rapid PVST+ operation.■■Chapter 6, “EtherChannel”:This chapter explains how to implement EtherChannelon switched links. It includes a description of EtherChannel technology, EtherChannelconfiguration, and EtherChannel troubleshooting.■■Chapter 7, “DHCPv4”:This chapter explains how to implement DHCPv4 for multipleLANs. It includes an explanation of DHCPv4 operation and how to configure a router asa DHCPv4 server or DHCPv4 client.■■Chapter 8, “SLAAC and DHCPv6”:This chapter explains how to implement dynamicaddress allocation in an IPv6 network. It includes an explanation of how an IPv6 hostacquires its addressing, SLAAC operation, DHCPv6 operation, and how to configure arouter as a stateful or stateless DHCPv6 server.■■Chapter 9, “FHRP Concepts”:This chapter explains how FHRPs provide defaultgateway services in a redundant network. It includes an explanation of the purpose ofFHRPs and HSRP operation.■■Chapter 10, “LAN Security Concepts”: This chapter explains how vulnerabilitiescompromise LAN security.
