A switch receives a frame on one of its ports. There is no entry in the MAC address table for the
destination MAC address. What will the switch do with the frame?
A.
drop the frame
B.
forward it out of all ports except the one that received it
C.
forward it out of all ports
D.
store it until it learns the correct port
Explanation:
Explanation/Reference:
Understanding this concept is prime for understanding that when switch receives the data frame
from the host not having the MAC address already in the MAC table, it will add the MAC address
to the source port on the MAC address table and sends the data frame. If the switch already has
the MAC address in it’s table for the destination, it will forward the frame directly to the destination
port. If it was not already in it’s MAC table, then they frame would have been flooded out all ports
except for the port that it came from.
