Episode 26: Virtual Network Interfaces and Components

This episode explores virtual network interfaces and components, which allow logical networking functions to operate independently of physical hardware. A virtual network interface card (vNIC) enables virtual machines or containers to communicate over networks just as a physical NIC would, while virtual switches, routers, and firewalls provide routing, segmentation, and security entirely in software. These concepts are essential to understand for the exam because virtualization is a core part of modern IT infrastructures.

The discussion also covers how these components are configured and integrated. You will learn how a virtual switch can connect multiple virtual machines within a hypervisor, how vNICs are mapped to physical adapters, and how virtual firewalls enforce policies in dynamic environments. Real-world troubleshooting scenarios are highlighted, such as diagnosing misconfigured vNICs or addressing conflicts between virtual and physical networks.
