Why Would a Layer 2 Switch Need an IP address?

0

To enable the switch to emit broadcast frames to associated PCs, 

to serve as a default gateway, 

to be administered remotely

to receive frames from attached PCs.

The correct answer is: to be administered remotely

Explanation:Because it is a Layer 2 device, a switch does not require an IP address to send frames to linked devices. When a switch is accessed remotely over the network, it requires a Layer 3 address. The IP address must be applied to a virtual interface instead of a physical interface. Routers, not switches, are the default gateways.
