Question 430
A switch receives BPDUs on an access edge configured with BPDU protection and disables the port. Which result would best establish that the correction succeeded?
Explanation
Correct Answer
This is an operational test of the required outcome rather than merely proof a setting exists. It checks that the edge protection is responding to an unexpected bridge on a user-facing port no longer prevents the service.
Incorrect Answers
This result may validate another network change, but it does not demonstrate recovery from the fault here: the edge protection is responding to an unexpected bridge on a user-facing port.
That explanation does not distinguish this option. “After master failure, clients continue using the virtual gateway through the surviving router” is an alternative action, but it does not by itself establish the outcome required in this case.
That explanation does not distinguish this option. “A single-member failure leaves all required server VLANs reachable” is an alternative action, but it does not by itself establish the outcome required in this case.
