Accepted Answer

A)  If the designated port is connected with P2P link, it can make a handshake with the connected bridge and enter the forwarding state immediately after it receives a response. 
B)  Once a port of the switch which is configured as edge port has been enabled, it will become designated port immediately and transit to forwarding state.
