If a switch receives a frame and the source MAC address is not in the ...
Explanation:

When a switch receives a frame, it looks up the destination MAC address in its MAC address table to determine the outgoing port. If the destination MAC address is found in the table, the switch forwards the frame out the corresponding port. However, if the source MAC address is not in the table, the switch must learn it before it can forward frames from that source.

The correct answer is option C - "Add the source address and port to the MAC address table and forward the frame out the destination port". This is because the switch has already learned the destination MAC address, so it knows which port to forward the frame out. However, it does not yet know the source MAC address, so it must learn it before it can forward frames from that source. Therefore, the switch adds the source MAC address and the port it received the frame on to its MAC address table, and then forwards the frame out the destination port.

Summary:

- When a switch receives a frame, it looks up the destination MAC address in its MAC address table to determine the outgoing port.
- If the destination MAC address is found in the table, the switch forwards the frame out the corresponding port.
- If the source MAC address is not in the table, the switch must learn it before it can forward frames from that source.
- The correct answer is option C - "Add the source address and port to the MAC address table and forward the frame out the destination port".
