Introduction to Networks: This first Module in the CCNA introduces architectures, models, protocols, and networking elements – functions needed to support the operations and priorities of Fortune 500 companies to small innovative retailers. You’ll even get the chance to build simple local area networks (LANs) yourself. You’ll have a working knowledge of IP addressing schemes, foundational network security, and be able to perform basic configurations for routers and switches. No prerequisites required.

Switching, Routing, and Wireless Essentials: This module focuses on switching technologies and router operations that support small-to-medium business networks, including wireless local area networks (WLAN) and security concepts. You’ll perform basic network configuration and troubleshooting, identify and mitigate LAN security threats, and configure and secure a basic WLAN. Recommended preparation: CCNA: Introduction to Networks or having equivalent knowledge.

Enterprise Networking, Security, and Automation: This third module in the CCNA series describes the architectures and considerations related to designing, securing, operating, and troubleshooting enterprise networks. It covers wide area network (WAN) technologies and quality of service (QoS) mechanisms used for secure remote access along with the introduction of software-defined networking, virtualization, and automation concepts that support the digitalization of networks. Recommended preparation: CCNA: Switching, Routing, and Wireless Essentials or possessing equivalent knowledge.
