Episode 105: VLANs — Segmenting the Network with Data and Voice

This episode introduces Virtual Local Area Networks (VLANs), which logically segment networks into separate broadcast domains on the same physical infrastructure. VLANs improve security, performance, and manageability by separating traffic such as user data and voice communications. VLANs are heavily emphasized on the exam because they are a core feature of modern switching.

Examples include configuring a voice VLAN for IP phones and a data VLAN for workstations on the same switch. Troubleshooting considerations include mismatched VLAN assignments, trunking misconfigurations, or devices placed in the wrong VLAN. By mastering VLAN concepts, you’ll be able to answer exam questions and apply VLANs effectively in enterprise environments.
