What are three advantages of RSTP over STP? (Choose three.)

A.
RSTP introduces the alternate port role, which provides additional bandwidth for traffic heading
to the root bridge.

B.
RSTP allows an alternate link to immediately transition to the forwarding state if the point-topoint link fails.

C.
RSTP allows a port to be an edge port when it connects to a LAN with no other bridges.

D.
RSTP introduces the backup port role, which allows multiple ports to pass traffic into the same
LAN segment at the same time.

E.
RSTP introduces the backup port role, which allows a second port on the shared LAN segment
to act as a backup port.
