Scope and Sequence: CCNA Exploration

Last Updated June 19, 2009

Target Audience
The Cisco® CCNA® Exploration curriculum is designed for Cisco Networking Academy® students who are seeking
entry-level information and communication technology (ICT) skills. CCNA Exploration provides an integrated and
comprehensive coverage of networking topics, from fundamentals to advanced applications and services, while
providing opportunities for hands-on practical experience and soft-skills development.

While primarily designed for postsecondary institutions, the curriculum is appropriate for students at many
education levels if they have the required skills, and if the instructional approach complements their learning style
and educational goals.

Prerequisites
CCNA Exploration is designed for students with advanced problem solving and analytical skills, such as students
pursuing degrees in engineering, information technology, math, or science. Students are expected to know binary
math and understand the concept of algorithms.

CCNA Exploration is composed of four courses: Network Fundamentals, Routing Protocols and Concepts, LAN
Switching and Wireless, and Accessing the WAN. Network Fundamentals is the first course and it has no
prerequisites. It is a prerequisite for the other three courses.

Routing Protocols and Concepts is the preferred second course in the sequence, but variations are possible as
shown in Figure 1. LAN Switching and Wireless can be taught before Routing Protocols and Concepts, or
concurrently. Network Fundamentals, Routing Protocols and Concepts, and LAN Switching and Wireless are all
prerequisites for Accessing the WAN.

Network Fundamentals
This course introduces the architecture, structure, functions, components, and models of the Internet and other
computer networks. It uses the OSI and TCP layered models to examine the nature and roles of protocols and
services at the application, network, data link, and physical layers. The principles and structure of IP addressing
and the fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the
curriculum. Labs use a “model Internet” to allow students to analyze real data without affecting production networks.
Packet Tracer (PT) activities help students analyze protocol and network operation and build small networks in a
simulated environment. At the end of the course, students build simple LAN topologies by applying basic principles
of cabling, performing basic configurations of network devices such as routers and switches, and implementing IP
addressing schemes.
