Designing and Supporting Computer Networks, CCNA Discovery Learning
Guide is the official supplemental textbook for the Designing and
Supporting Computer Networks course in the Cisco® Networking Academy® CCNA®
Discovery curriculum version 4. In this course, the last of four in the new
curriculum, you progress through a variety of case studies and role-playing
exercises, which include gathering requirements, designing basic networks,
establishing proof-of-concept, and performing project management tasks. In
addition, within the context of a pre-sales support position, you learn
lifecycle services, including upgrades, competitive analyses, and system
integration.
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.
The Learning Guides features help you focus on important concepts to
succeed in this course:
- Chapter ObjectivesReview core concepts by answering the focus questions
listed at the beginning of each chapter.
- Key TermsRefer to the lists of networking vocabulary introduced and
highlighted in context in each chapter. The Glossary defines each key
term.
- Summary of Activities and LabsMaximize your study time with this complete
list of all associated exercises at the end of each chapter.
- Check Your UnderstandingEvaluate 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 ActivitiesApply a deeper understanding of the
concepts with these challenging end-of-chapter questions and activities. The
answer key explains each answer.
- Hands-on LabsMaster the practical, hands-on skills of the course by
performing all the tasks in the course labs included in Part II of the Learning
Guide.
- Portfolio DocumentsDevelop a professional network design portfolio as you
work through real-life case studies. All the course portfolio documents and
support materials are provided for you in this Learning Guide and on the
CD-ROM.
