A switch receives a frame with a destination MAC address that is currently not in the MAC table What action does the switch perform?

It duplicates the frame to all Ethernet ports, except the port it came from.
A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
