11. Refer to the exhibit. Switches A and C are running PVST+ STP, and Switch B is running 802.1Q STP. If the
BPDU of the root in VLAN 1 is better than the BPDU of the root in VLAN 2, then there is no blocking port in the
VLAN 2 topology. The BPDU of VLAN 2 never makes a "full circle" around the topology; it is replaced by the
VLAN 1 BPDU on the B-C link, because B runs only one STP merged with VLAN 1 STP of PVST+. Thus, there
is a forwarding loop.

C. Switch C will put port C-B into a type-inconsistent state, which prevents the loop.
B. Switch B sends PVST+ BPDUs of VLAN 1 (to the SSTP address that is flooded by Switch A) towards Switch
C. Switch C will put port C-B into a type-inconsistent state, which prevents the loop.
C. Switch C sends PVST+ BPDUs of VLAN 2 (to the SSTP address that is flooded by Switch B) towards Switch
C. Switch A will put port C-B into a type-inconsistent state, which prevents the loop.
D. Switch A sends PVST+ BPDUs of VLAN 1 (to the SSTP address that is flooded by Switch B) towards Switch
B. Switch A will put port C-B into a type-inconsistent state, which prevents the loop.
