Which switch would STP choose to become the root bridge in the selection process?
A. 32768: 11-22-33-44-55-66
B. 32768: 22-33-44-55-66-77
D. 32769: 22-33-44-55-66-78
Correct Answer: A
Root switches are elected on the lowest priority. If two switches have the same priority, then the one with the lowest MAC address is chosen. Out of the four choices
here, A and B have the lowest priority, and A has the lowest MAC address, so A is chosen.
