Refer to the exhibit. On the basis of the output of the show spanning-tree inconsistentports command, which statement about interfaces FastEthernet 0/1 and FastEthernet 0/2 is true?
A.
They have been configured with the spanning-tree bpdufilter disable command.
B.
They have been configured with the spanning-tree bpdufilter enable command.
C.
They have been configured with the spanning-tree bpduguard disable command.
D.
They have been configured with the spanning-tree bpduguard enable command.
E.
They have been configured with the spanning-tree guard loop command.
F.
They have been configured with the spanning-tree guard root command.
Explanation:
If another switch advertises a superior BPDU, or one with a better Bridge ID, on a port where root guard is enabled, the local switch will not allow the new switch to become the root. As long as the superior BPDUs are being received on the port, the port will be kept in the root-inconsistent STP state.
