| Question ID 14456 | 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?
|
| Option A | drop the frame
|
| Option B | forward it out of all ports except the one that received it
|
| Option C | forward it out of all ports
|
| Option D | store it until it learns the correct port
|
| Correct Answer | B |
Explanation Explanation: 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 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.
