.Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?
A. SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
B. SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.
C. SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
D. SW1 drops the frame because it does not know the destination MAC address.
