When a switch receives a frame from an unknown source MAC address, which action does the switch take with the frame?

  • AIt sends the frame to ports within the CAM table identified with an unknown source MAC address.
  • BIt floods the frame out all interfaces, including the interface it was received on.
  • CIt associates the source MAC address with the LAN port on which it was received and saves it to the MAC address table. (correct answer)
  • DIt attempts to send the frame back to the source to ensure that the source MAC address is still available for transmissions.
Reveal answer & explanation
Correct answer: C

The correct answer is C. Option C: It associates the source MAC address with the LAN port on which it was received and saves it to the MAC address table.
