MAC addresses are burned into the networking hardware. They are, in theory, unique in the world. Cloning is a software process that translates the MAC address when sending packets.

Virtuall all operating systems allow you to change the MAC address of a NIC. MAC "cloning" is the practice of changing your MAC address to that of one that is authorized on a system.
Since it is childs play to determine the MAC addresses of all NICs on an unencrypted network, MAC filtering is a very poor way to secure a network.
The advanced properties for any NIC has an option for changing the MAC address, including Realtek. Sometimes it's called "locally administered address" or someting similar, but the option is there for all NICs.

MAC cloning can be very useful when troubleshooting network problemsor monitoring specific machines, but both 1 and 2 are correct
