Which switch provides the spanning-tree designated port role for the network segment that
services the printers?

A.
Switch1

B.

Explanation:
Printers are connected by hubs. Decide the switch that provides the spanning-tree designated port

addresses. Switch3 with a smaller MAC address will provide a designated port for printers.
