how will SwitchA handle this frame?

Refer to the exhibit.

SwitchA receives the frame with the addressing shown. According to the command output also
shown in the exhibit, how will SwitchA handle this frame?

A.
It will drop the frame.

B.
It will forward the frame out port Fa0/3 only.

C.
It will flood the frame out all ports.

D.
It will flood the frame out all ports except Fa0/3.

Explanation:
Switches learn the MAC addresses of PCs or workstations that are connected to their switch ports
by examining the source address of frames that are received on that port.
Machines may have been removed from a port, turned off, or moved to another port on the same
switch or a different switch.
This could cause confusion in frame forwarding.
The MAC address entry is automatically discarded or aged out after 300 seconds
If there is not MAC address of destination host in MAC table, switch sends broadcast to all ports
except the source to find out the destination host.
In the output there is no MAC address of the given host so the switch will flood to all ports except
the source port, which is port fa 0/3.
