How will SwitchB handle the frame it just received?
A.
It will forward the frame out all ports
B.
It will forward the frame out FastEthernet0/4 only
C.
It will drop the frame
D.
It will record the source MAC address
E.
It will forward the frame out FastEthernet0/10 only
Explanation:
SwitchB will forward the frame out FastEthernet0/10 only. The MAC address table indicates that the switch has
the destination MAC address in its table and the destination is located on switch port FastEthernet 0/10,
therefore it will switch the frame to that interface.
It will not forward the frame out all ports. It will only do that when it receives a frame for which it knows no
destination and then it will forward it out all ports except the one on which it arrived. For example if it were
sending a frame to 00c0.5658.d26e, which is nowhere to be found in the table and the frame arrived on port
FastEthernet0/10 it would send the frame to very port except FastEthernet0/10.
It will not forward the frame out FastEthernet0/4. The MAC address located on that port is 00c0.57ce.ce33,
which means that is the port on which the frame arrived.
It will not drop the frame. It will not drop the frame when it has the destination in its MAC table.
It will record the source MAC address. That address is already present in the table.
