Routing Protocols and Concepts: CCNA Exploration Labs and Study Guide (2nd Revised edition)
Routing Protocols and Concepts, CCNA Exploration Labs and Study Guide is designed to support your learning routing protocols and concepts in Version 4 of the Cisco Networking Academy CCNA(R) Exploration curriculum. Each chapter contains a Study Guide section and a Labs and Activities section. Study Guide The dozens of exercises in this book help you
learn the concepts and configurations crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes multiple-choice, fill-in-the-blank, and open-ended questions designed to help you: Review vocabulary Strengthen troubleshooting skills Boost configuration skills Reinforce concepts Research topics Packet Tracer Activities: This icon identifies exercises interspersed throughout the Study Guide section where you can practice or visualize a specific task using Packet Tracer, a powerful network simulation program developed by Cisco. Labs and Activities: The Labs and Activities sections begins with a Command Reference table and includes all the online curriculum labs to ensure that you have mastered the practical skills needed to succeed in this course. Hands-On Labs: This icon identifies the hands-on labs created for each chapter. Work through all the Basic, Challenge, and Troubleshooting labs as provided to gain a deep understanding of CCNA knowledge and skills to ultimately succeed on the CCNA Certification Exam. Packet Tracer Companion: This icon identifies the companion activities that correspond to each hands-on lab. You use Packet Tracer to complete a simulation of the hands-on lab. Packet Tracer Skills Integration Challenge: Each chapter concludeswith a culminating activity called the Packet Tracer Skills Integration Challenge. These challenging 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. Allan Johnson works full time developing curriculum for Cisco Networking Academy. Allan also is a part-time instructor at Del Mar College in Corpus Christi, Texas.
