Refer to the exhibit. A PC with the MAC address of 0800.069d.3841 attached to port Fa0/8 is sending data to a device that has the MAC address of 6400.6a5a.6821. What will the switch do first to handle the data transfer?
The switch will add the address 6400.6151.6821 to the MAC address table.
The switch will send the frame to ports Fa0/4 and Fa0/6.
The switch will add the address 0800.069d.3841 to the MAC address table.
The switch will send the frame to port Fa0/6.
The switch will flood the frame out all ports except port Fa0/8.
The switch will add the address 0800.069d.3841 to the MAC address table.
Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?
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.
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.
SW1 drops the frame because it does not know the destination MAC address.
SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
What are two actions performed by a Cisco switch? (Choose two.)
utilizing the MAC address table to forward frames via the destination MAC address
