Network Engineer Foundations: Routing, Switching, and Modern Automation

The modern world runs on interconnected networks, making skilled network engineers more vital than ever. If you want to understand how data moves across the globe and how to design secure, reliable systems, starting with the right fundamentals is key. This written course guides you from absolute networking basics to configuring routing, switching, and modern automated environments. You will transition from someone who simply uses the internet to a professional who understands, designs, and troubleshoots the infrastructure supporting it. What you'll learn: - Understand the foundational OSI and TCP/IP models, IP addressing, subnetting, and core network protocols. - Configure basic routing and switching environments, including VLANs, static routing, and dynamic protocols. - Apply modern security principles, including access control lists (ACLs) and zero-trust security concepts to protect network perimeters. - Analyze network traffic and troubleshoot common connectivity issues using standard command-line tools. - Explore network automation basics, including how Python and structured data formats are used to manage modern infrastructure. - Discover cloud networking fundamentals, understanding how on-premises networks connect to virtual private clouds. You will begin by mastering essential terminology and subnetting mathematics before moving on to practical routing and switching concepts. The course wraps up with an introduction to modern network security, automation, and hybrid cloud integration. This course is designed specifically for beginners with no prior networking experience who want a clear, structured path into the IT infrastructure field.
