CCNP Certification / BCMSN Exam:
Short answer: Can a switch be configured to open an err-disabled port on its own, rather than require manual intervention? If so, how?
Answer: Yes, with the errdisable recovery command. Otherwise, the port stays in err-disabled state until you manually reopen the port.
CCNP Certification / ONT Exam:
Short answer: You've just completed a CBWFQ configuration - almost. You want to apply the policy map CCNP to traffic leaving interface serial0. What command on S0 will do this?
Answer: service output CCNP. This is the command to apply the policy, but you'll need to disable flow-based WFQ as well with the no fair-queue command on that interface.
See you later today with more practice questions and answers, plus a new tutorial!
