What protocol was used in this scenario?  ARP  DHCP  DNS  WINS Q.12 A switch receives a frame with a destination MAC address that is currently not in the MAC table. What action does the switch perform?  It drops the frame.  It sends out an ARP request looking for the MAC address.  It floods the frame out of all active ports, except the origination port.  It returns the frame to the sender.
