What two things will occur when an edge port receives a BPDU? (Choose two.)
A.
The port immediately transitions to the Forwarding state.
B.
The switch generates a Topology Change Notification (TCN) BPDU.
C.
The port immediately transitions to the err-disable state.
D.
The port becomes a normal STP switch port.
Explanation:
An edge port that receives a BPDU immediately loses edge port status and thus becomes a normal port in the spanning-tree topology going through the Discarding -> Learning -> Forwarding stages.
TCN only gets sent when the topology has converged…. thus meaning the port must be in forwarding state for a TCN to be sent.
