Suggested Answer: D Vote an answer
Switches learn the MAC addresses of PCs or workstations that are connected to their switch ports
by examining the source address of frames that are received on that port.
Machines may have been removed from a port, turned off, or moved to another port on the same
switch or a different switch.
This could cause confusion in frame forwarding.
The MAC address entry is automatically discarded or aged out after 300 seconds
If there is not MAC address of destination host in MAC table, switch sends broadcast to all ports
except the source to find out the destination host.
