Question:
Why would a Layer 2 switch need an IP address?
- to enable the switch to send broadcast frames to attached PCs
- to enable the switch to function as a default gateway
- to enable the switch to be managed remotely
- to enable the switch to receive frames from attached PCs
Explanation: A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface. Routers, not switches, function as default gateways.
