  1. C is the correct answer

    To recover a port that is in an Errdisable state, manual intervention is required, and the administrator must access the switch and configure the specific port with ‘shutdown’ followed by the ‘no shutdown’ command. This command sequence will enable the port again.

    According to below Cisco link, A,B & D are incorrect.

  2. Took the exam and passed last week.
    50% of the questions were from this site.
    The rest was completely new.
    Lots of Drag & Drop Qs.

  3. if anyone doing the exam any soon, please leave a feedback if these are still kinda accurate.
    i have heard that around 10% of these question are still valid. none of the Sims.
    is it worth it to get the vcePlus verison of questions?

  4. Answer is C.

    When a violation occurs on a switch port in restrict mode: the frame is dropped and will only accept traffic from known mac addresses.

    Violation protect mode doesn’t generate syslogs.
    A switch using port security will not allow traffic from unknown MAC addresses.

  5. Good chance you will see theses questions, but it’s not a guarantee because they pull from about 600 questions
