SW1 will repeatedly forward a Hello out its fa0/4 interface with cost 19.
SW4's interface Fa0/1 will become the designated port on the link between SW1 and SW4.
SW4 will repeatedly forward a Hello out its fa0/1 interface with cost 10.
SW3’s fa0/2 interface will be its root port.

The diagram of a small switched network, with all switches acting as layer 2 switches in VLAN 10. The diagram notes the switch chosen as root switch, with each root port noted with the letters RP and each designated port noted with the letters DP.

Which of the following statements about RSTP states and roles in this network are true?
SW2’s port Gi0/1 must be in an alternate port role.
SW1’s port Gi0/1 might be in an alternate port role.
SW2’s port Gi0/1 must be in a backup port role.
SW1’s port Gi0/1 might be in a backup port role.
