CCNA Foundations: Routing, Switching, and VLANs

Building a reliable network requires more than just connecting hardware; it demands a deep understanding of how data moves across switches and routers. This course provides the conceptual framework and practical logic needed to manage enterprise-level network traffic and ensure seamless connectivity. You will transform your understanding of how data travels from source to destination, gaining the skills to organize and secure network segments effectively. By focusing on the internal operations of networking hardware, you will learn to troubleshoot and optimize traffic flow in diverse environments. What you'll learn: - Understand the mechanics of OSI Layers 1 and 2 and how Ethernet frames travel across a network - Configure and manage VLANs to optimize network performance and segmentation - Apply routing principles to direct traffic efficiently between different subnets - Master the logic of switching and how devices maintain MAC address tables - Implement basic network security measures and access control lists (ACLs) - Explore modern networking trends including software-defined networking (SDN) basics and network automation concepts The course begins with essential terminology and the physical foundations of networking before moving into the logical configuration of switches and routers. You will progress through written scenarios that illustrate how to handle real-world traffic demands. This course is designed for beginners who want a structured path into networking and those looking to solidify their knowledge of core infrastructure. No prior networking experience is required.
