Chapter 1: Overview
 Businesses rely on the network infrastructure to provide missioncritical services.
 Network designers must design and build an enterprise network that
is scalable and highly available.
 This chapter introduces strategies that can be used to
systematically design a highly functional network, such as the
hierarchical network design model, the Cisco Enterprise
Architecture, and appropriate device selections.
 The goals of network design are to limit the number of devices
impacted by the failure of a single network device, provide a plan
and path for growth, and create a reliable network.

Chapter 1: Best Practices
Prior to teaching Chapter 1, the instructor should:
 Complete Chapter 1 exam.
 Have students evaluate their school’s network design. How does it
compare to the hierarchical or modular design model?
 Invite the head of IT to discuss the school’s network design with the
class.
 Provide hands-on activities to review and practice basic switch and
router configuration.
 Use the Syntax Checker to practice switch and router configuration.
 Visit http://www.cisco.com for more information on Cisco devices.
