Refer to the exhibit.
Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4.
What will Switch-1 do with this data?
A. Switch-1 will drop the data because it does not have an entry for that MAC address.
B. Switch-1 will forward the data to its default gateway.
C. Switch-1 will flood the data out all of its ports except the port from which the data originated.
D. Switch-1 will send an ARP request out all its ports except the port from which the data originated.
Correct Answer: C
The switch has to try to deliver the frame, but it doesn’t know in which direction the host is. In this situation, the switch sends the frame out on all ports (except the
one which received the frame) in the hope that the frame will eventually get received. If and when that host replies, the reply frame will come into the switch, and the
switch will take the (now) source MAC address of 00b0.d056.efa4 and add it to the switching table.
