The mac address and priority are to separate things that make up the Bridge ID.
In STP the switches look at the priority first, the lowest becomes the root bridge. If all or some of the priority numbers are the same (this will happen most of the time *default priority= 32768* ) they then look at the mac addresses, the lowest mac address becomes the root bridge.
you can change the mac address of a switch but its almost never done and way outside the scope of this test. so for this test you cant change the mac address of any device.
did this answer your question?
