    Not sure about the answer to Question 2 (Even without an exhibit):

    Question 2

    A question about UDLD port disable.

    A. When a link is repaired, the administrator must enter udld reset command to recover disabled interfaces.
    B. When a link is repaired, the administrator must enter err-disable recovery cause udld command to recover disabled interfaces.
    C. UDLD puts the port in STP inconsistent port mode.
    D. ?

    Answer: C

    In normal mode, if the link state of the port was determined to be bi-directional and the UDLD information times out, no action is taken by UDLD. The port state for UDLD is marked as undetermined. The port behaves according to its STP state.

    In aggressive mode, if the link state of the port is determined to be bi-directional and the UDLD information times out while the link on the port is still up, UDLD tries to re-establish the state of the port. If not successful, the port is put into the errdisable state.
