In RSTP, which three port roles are associated with the discarding state? (Choose three.)
In RSTP (Rapid Spanning Tree Protocol), the three port roles associated with the discarding state are backup, alternate, and disabled. The discarding state is a state where the port does not forward frames and does not learn MAC addresses. A backup port provides a redundant pathway to the same segment, an alternate port offers a different path to the root bridge, and a disabled port is administratively shut down.
