INTRODUCTION

Introduction
The Cisco Designing for Cisco Internetwork Solutions (DESGN) exam
is the required exam for the Cisco Certified Design Associate (CCDA)
certification. Objectives for the DESGN exam include the following:
n Describe a systematicand modular approach to design.
n Design enterprise campus, enterprise data center, enterprise edge,

and remote modules.
n Assign an appropriate IP addressing scheme.
n Select an appropriate routing protocol.
n Specify security solutions.
n Provide support for voice traffic.
n Offer a solution for basic wireless connectivity.

These Quick Reference Sheets summarize the main topicspresented on
the DESGN exam. The information presented represents the content
covered on exam number 640-863.

CHAPTER 1

Cisco recently updated its Architecture for VoiceVideo and Integrated
Data (AVVID) design approach to the Intelligent Information Network
(IIN). IIN is a complete architecture that is more all encompassing than
AVVID.
The three phases of constructing an IIN are as follows:
n Integrated transport—Voice, data, and video are all converged

onto a single transport.
n Integrated services—Services, such as VoIP or storage network-

ing, relyon the underlying network transport mechanisms.
n Integrated applications—Applications (for example, Cisco IP

Communicator) leverage services (for example, VoIP), which rely
on the network transport.

Architecture (SONA) framework for network design. In addition, you
learn how to examine characteristics of an existing network, while
determining design requirements. Finally, this section discusses Cisco’s
top-down approach to network design.

The Cisco architectural approach to designing an IIN is their SONA
framework.Figure 1-1 shows individual IIN components and how those
components are categorized by SONA’s three layers: networked infrastructure layer, infrastructure services layer, and application layer.
