Which two statements are true about STP port states? (Choose two.)

The correct answer is B. A port that has been administratively disabled under the STP protocol drops all BPDUs. C. In the learning state, the port drops all data packets. B: A port in the disabled state is manually isolated from the network. A port in the disabled state does not participate in frame forwarding or the operation of STP because a port in the disabled state is considered non-operational. C: The learning state is a 15-second interval…

Explanation

B: A port in the disabled state is manually isolated from the network. A port in the disabled state does not participate in frame forwarding or the operation of STP because a port in the disabled state is considered non-operational. C: The learning state is a 15-second interval during which the bridge does not pass user data frames while the bridge is building its bridging table. As the bridge receives frames, it places the source MAC address and port of each frame into the bridging table. The learning state reduces the amount of flooding required when data forwarding begins.
