Syllabus

Welcome

In this module, we will introduce you to the course, explain the significance of CCNA certification for your career, and provide a roadmap to guide your studies for success.

How to Set Up the Lab

In this module, we will guide you through setting up your lab environment by installing Cisco Packet Tracer and configuring your system for effective hands-on practice.

Host to Host Communications

In this module, we will introduce you to the core principles of network communication, covering the OSI model, TCP/IP stack, and how data travels between devices over a network.

The Cisco IOS Operating System

In this module, we will explore the Cisco IOS operating system, teaching you how to connect to Cisco devices, navigate the interface, and manage configurations effectively.

OSI Layer 4 - The Transport Layer

In this module, we will dive into the transport layer, focusing on TCP and UDP protocols, their roles in ensuring reliable communication, and how to read transport layer headers.

OSI Layer 3 - The Network Layer

In this module, we will cover OSI Layer 3, focusing on the IP header, different types of network traffic, and key subnetting principles to optimize network performance.

IP Address Classes

In this module, we will explore IP address classes in detail, explaining how different address classes are structured and when each is applied in networking environments.

Subnetting

In this module, we will provide an in-depth look at subnetting, with practical examples and exercises to help you understand CIDR, VLSM, and how to segment large networks.

OSI Layer 2 - The Data-Link Layer

In this module, we will discuss the data-link layer and its protocols, focusing on Ethernet standards and how Layer 2 facilitates local network communication.

OSI Layer 1 - The Physical Layer

In this module, we will focus on the physical layer, explaining how data is transmitted over physical media like cables and how to choose the correct connection types for networks.

Cisco Device Functions

In this module, we will introduce the various Cisco networking devices, from switches to routers, explaining how each device functions within a network and their differences.

The Life of a Packet

In this module, we will trace the path of a packet across a network, highlighting key protocols like DNS and ARP, and providing practical examples of packet flow through various layers.

The Cisco Troubleshooting Methodology

In this module, we will cover Cisco’s troubleshooting methodology, teaching you how to systematically approach and resolve network issues in both theory and lab environments.

Cisco Router and Switch Basics

In this module, we will introduce basic router and switch configurations, covering topics like speed settings, duplex modes, and troubleshooting common network issues.

Cisco Device Management

In this module, we will explore the essentials of Cisco device management, including the boot process, factory reset procedures, and how to backup and upgrade configurations.
