Compared with STP, which of the following port roles does RSTP add? (Choose all that apply.)
Compared with STP, which of the following port roles does RSTP add? (Choose all that apply.)
Compared with STP, RSTP introduces two additional port roles: Alternate port and Backup port. The Alternate port provides an alternative path to the root switch and can quickly transition to the forwarding state if the current path fails. The Backup port offers a redundant connection on a network segment where another switch port is already actively forwarding packets. The roles of Root port and Designated port are present in both STP and RSTP, so they are not new additions made by RSTP.
Correct Answer: C. Alternate port D. Backup port
CD are correct

C y D correctas Alternate Port: This is a new role introduced in RSTP. An alternate port is one that provides an alternative path to the root switch, different from the path that the root port takes. It's in a blocking state but can transition to forwarding quickly if the network topology changes and the primary path (via the root port) fails. Backup Port: This is another new role introduced in RSTP. A backup port provides a redundant (backup) path to a segment where another switch port already connects. This port is also in a blocking state, and will only become active if the designated port for that segment fails.
Alternate and Backup are new roles compared to STP
