Question 857

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

It sends the frame to ports within the CAM table identified with an unknown source MAC address.

It floods the frame out all interfaces, including the interface it was received on.

It associates the source MAC address with the LAN port on which it was received and saves it to the MAC address table.

It attempts to send the frame back to the source to ensure that the source MAC address is still available for transmissions.

Correct Answer: C

When a switch receives a frame from an unknown source MAC address, it associates the source MAC address with the LAN port on which it was received and saves it to the MAC address table. This helps the switch keep track of which MAC addresses are reachable on which ports, optimizing future network traffic handling.
