Foundation Summary

The "Foundation Summary" section of each chapter lists the most important facts from the chapter. Although this section does not list every fact from the chapter that will be on the CCDA exam, a well-prepared CCDA candidate should at a minimum know all the details in each "Foundation Summary" before taking the exam.

Table 1-8 compares the top-down design approach to the bottom-up design approach. Table 1-8 Top-Down Design Compared to Bottom-Up Design

Design Approach

Benefits

Disadvantages

Top-down

Incorporates the organization's requirements. Provides the big picture. The design meets current and future requirements.

More time-consuming.

Bottom-up

The design is based on previous experience and allows for a quick solution.

May result in inappropriate design. Organizational requirements are not included.

Table 1-9 summarizes the sections of the design document.

Table 1-9 Sections of the Design Document

Section

Description

Introduction

Purpose and goals of the network design.

Design Requirements

Organization requirements and constraints.

Existing Network Infrastructure

Contains diagrams, hardware and software versions, and existing configurations.

Design

New logical topology, design, and IP addressing.

Proof of Concept

Results from pilot or prototype.

Implementation Plan

Detailed steps for implementation.

Appendixes

Supporting information.
