The Cisco CCNA Discovery curriculum provides foundational networking knowledge, practical experience, opportunities for career exploration, and soft-skills development to help you prepare for entry-level careers in IT and networking. The curriculum offers a hands-on approach to learning, and uses interactive tools and easy-to-follow labs to help you learn the general theory needed to build networks. While extensive online study resources and comprehensive textbooks are available, many students and instructors have requested a low-cost printed resource that can be used to study in places where Internet access may not be available. This booklet is that resource. Drawn directly from the online curriculum, it covers every skill and competency presented in the CCNA Discovery Introducting Routing and Switching in The Enterprise course. This simple, straightforward booklet gives you new flexibility to study offline, highlight key points, and take handwritten notes. All topics are correlated directly to online web pages, helping you easily switch between offline and online content.
