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.

What address does a switch build into its table to successfully send data to that device?

A switch builds a MAC address table, which contains the MAC addresses of devices connected to its ports along with the corresponding port numbers. When a switch receives a data frame, it reads the source MAC address and updates its table if the address is not already present. To send data to a specific device, the switch looks up the destination MAC address in its table and forwards the frame out of the appropriate port associated with that address. If the destination address is not found, the switch broadcasts the frame to all ports except the one it received it on.
