On which device do you configure VLANs?

1. Wireless repeater

2. Hub

3. Switch

4. Router

The correct answer is: Switch

The correct answer is the switch, as VLANs (Virtual Local Area Networks) are primarily configured on network switches. A VLAN allows network segmentation, which enhances security and improves performance by isolating broadcast domains within a network. Switches operate at the data link layer (Layer 2) and are capable of managing traffic based on MAC addresses, which is essential for implementing VLANs. When configuring VLANs on a switch, administrators can group devices logically even if they are not in the same physical location. This provides flexibility in network design and efficient use of resources, enabling better traffic management and enhanced security. In contrast, while routers can also handle VLANs (especially in routing between them), the initial configuration and management of VLANs typically happen on switches. Hubs, being simplistic devices that do not operate at Layer 2, do not have VLAN capabilities. Wireless repeaters do not support VLAN configuration as they merely extend signal coverage and do not involve traffic management or separation functionalities like switches do.
