A switch receives an Ethernet frame addressed to a computer connected to one of its ports. After learning the destination MAC address, what will the switch normally do?
- A.Send the frame only through the port associated with that MAC addressCorrect answer
- B.Convert the frame into an optical signal and send it to every port
- C.Replace the destination MAC address with the destination IP address
- D.Discard the frame because switches do not use MAC addresses
