Correct answer : D
Forwarding State
A port in the forwarding state forwards frames across the attached network segment. In a forwarding state, the port will process BPDUs , update its MAC Address table with frames that it receives, and forward user traffic through the port. Forwarding State is the normal state. Data and configuration messages are passed through the port, when it is in forwarding state.
