How are VLANs typically configured on a network switch?

1. Through the VLAN management tool on a server

2. By adjusting the router's configuration settings

3. By configuring VLAN numbers and names in the switch

4. Using a dedicated VLAN control panel

The correct answer is: By configuring VLAN numbers and names in the switch

VLANs, or Virtual Local Area Networks, are typically configured directly on a network switch. This process involves assigning specific VLAN numbers and names in the switch's configuration settings. Each VLAN serves as a separate broadcast domain, allowing for segmentation of network traffic to improve performance and security. When configuring VLANs on a switch, network administrators utilize commands or a graphical user interface to define which ports belong to which VLAN. This setup enables devices connected to those ports to communicate with each other, while restricting traffic from devices in different VLANs unless routing is provided. The other options do not accurately reflect the common methods for VLAN configuration. A VLAN management tool on a server is not the standard method; VLAN management and configuration typically occur at the switch level. Adjusting a router's configuration settings is related to inter-VLAN routing but does not configure VLANs themselves. Lastly, while some network appliances might have dedicated control panels, this is not a standard method used across all switches, making it less common than configuring VLANs directly in the switch’s settings.
