Which of the following statements about STP bridge ID is correct?

Which of the following statements about STP bridge ID is correct?
A . The bridge with the smallest bridge ID in the network will eventually become the root bridge after STP calculation.
B . The bridge ID consists of the bridge MAC address and the priority field. When comparing bridge IDs, the MAC address is compared first, and the one with the smaller MAC address value is preferred.
C . The MAC addresses of SWA and SWB are 00-E0-FC-00-00-11 and 00-E0-FC-11-00-11 respectively, and their priorities are 32768
and 4096, when SWA and SWB are connected in a ring network and the spanning tree protocol is enabled, SWA will become the root bridge.
D . The bridge priority field is 2 bytes long, so the bridge priority value range is 0-65535

Answer: A
