CCNA 2 Labs and Study Guide


Allan Johnson


The only authorized Labs and Study Guide for the Cisco Networking Academy Program


Routers and Routing Basics CCNA 2 Labs and Study Guide supplements version 3.1.1 of the Cisco Networking Academy® Program CCNA® 2 course. This Guide maximizes your understanding of:

  • Configuring a router
  • Managing Cisco IOS® Software
  • Selecting a routing protocol
  • Verifying and troubleshooting a network
  • Implementing basic security with access control lists


Each chapter contains a Study Guide section and a Lab Exercises section. Keep all your completed work on hand in this book to study from later, or take advantage of the perforated pages to tear out and hand in specific material for homework assignments.


Study Guide

Over 200 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 some or all the following types of exercises:

  • Vocabulary matching and completion
  • Skill building activities and scenarios
  • Configuration scenarios
  • Concept questions
  • Journal entries
  • Internet research


Lab Exercises

The Lab Exercises sections begin with a Command Reference exercise to help you review all the commands covered in the chapter. The book includes all 55 labs from the online course with an additional 15 labs in which you can apply your knowledge about the technologies and concepts introduced. You will get ample opportunity for hands-on practice in three different types of labs:

  • Curriculum Labs are step-by-step exercises designed to introduce you to new concepts. Presenting you with detailed instructions and sometimes additional explanations for completing the lab, Curriculum Labs come directly from the CCNA 2 online course.
  • Comprehensive Labs combine the concepts learned from the course and Curriculum Labs into new experiments. These Exercises provide minimal guidance. You are encouraged to complete the Curriculum Labs before moving on to a Comprehensive Lab.
  • Challenge Labs are unique labs requiring a thorough understanding of the previously learned network concepts. You should complete all Curriculum Labs and Comprehensive Labs before attempting a Challenge Lab.


Additionally, the appendix includes a CCNA 2 Skills-Based Assessment practice lab.


After completing all the exercises and hands-on labs in this book, you will be well prepared to continue your networking education in the CCNA courses that follow.
