CCNA Discovery Learning Guide

Working at a Small-to-Medium Business or ISP, CCNA Discovery Learning Guide is the official supplemental textbook for the Working at a Small-to-Medium Business or ISP course in the Cisco® Networking Academy® CCNA® Discovery curriculum version 4.1. The course, the second of four in the new curriculum, teaches networking concepts by applying them to a type of network you might encounter on the job in a small-to-medium business or ISP. After successfully completing the first two courses in the CCNA Discovery curriculum, you can choose to complete the CCENT® (Cisco Certified Entry Network Technician) certification exam, which would certify that you have developed the practical skills required for entry-level networking support positions and have an aptitude and competence for working with Cisco routers, switches, and Cisco IOS® Software.

The Learning Guide, written and edited by instructors, is designed as a portable desk reference to use anytime, anywhere to reinforce the material from the course and organize your time. In addition, the book includes expanded coverage of CCENT/CCNA exam topics.

The book’s features help you focus on important concepts to succeed in this course:

• Chapter Objectives—Review core concepts by answering the focus questions listed at the beginning of each chapter.
• Key Terms—Refer to the lists of networking vocabulary introduced and highlighted in context in each chapter. The Glossary defines each key term.
• Summary of Activities and Labs—Maximize your study time with this complete list of all associated exercises at the end of each chapter.
• Check Your Understanding—Evaluate your readiness with the end-of-chapter questions that match the style of questions you see in the online course quizzes. The answer key explains each answer.
• Challenge Questions and Activities—Apply a deeper understanding of the concepts with these challenging end-of-chapter questions and activities. The answer key explains each answer.
• Hands-on Labs—Master the practical, hands-on skills of the course by performing all the tasks in the course labs and additional challenge labs included in Part II of the Learning Guide.
