Refer to the exhibit.
The ports that are shown are the only active ports on the switch. The MAC address table is shown
in its entirety. The Ethernet frame that is shown arrives at the switch.
What two operations will the switch perform when it receives this frame? (Choose two.)
A.
The MAC address of 0000.00aa.aaaa will be added to the MAC address table.
B.
The MAC address of 0000.00dd.dddd will be added to the MAC address table.
C.
The frame will be forwarded out port fa0/3 only.
D.
The frame will be forwarded out fa0/1, fa0/2, and fa0/3.
E.
The frame will be forwarded out all the active ports.
Explanation:
If the switch already has the MAC address in its table for the destination, it will forward the frame
directly to the destination port. If it was not already in its MAC table, then they frame would have
been flooded out all ports except for the port that it came from. It will also add the MAC address of
the source device to its MAC address table
According to the explanation the answer will be A & C
@bash. The switch doesn’t know on what port mac dddd is. Meaning it cant be added to the table. The question is what happens when it RECIEVES the frame from aaaa.
And as it also doesn’t know mac aaaa it will be added first. So A & D is still correct. (Only after dddd responds the switch adds the mac and port to its table.)
