Question 30
A switch receives BPDUs on an access edge configured with BPDU protection and disables the port. Which immediate engineering change most directly addresses this issue?
Explanation
Correct Answer
The underlying issue is that the edge protection is responding to an unexpected bridge on a user-facing port. This intervention addresses that cause directly. A useful result to confirm is: the endpoint port remains healthy without permitting a rogue bridging device.
Incorrect Answers
This is suited to a different condition, such as when a campus uses VRRP on an SVI but hosts keep targeting a physical gateway address rather than the shared virtual address. The reported fault instead arises because the edge protection is responding to an unexpected bridge on a user-facing port.
This is suited to a different condition, such as when a VSX deployment uses a keepalive route through the same physical links as its inter-switch link. The reported fault instead arises because the edge protection is responding to an unexpected bridge on a user-facing port.
This is suited to a different condition, such as when a redundant OSPF network has two uplinks, but one interface's routing adjacency never forms because its area ID is wrong. The reported fault instead arises because the edge protection is responding to an unexpected bridge on a user-facing port.
