    CORRECT ANSWER is –

    Answer: B
    Explanation: Issue: show policy-map interface gi0/0
    First find out which policy-map is applied (it called something like QOSPOLICY1)
    A is wrong. Class MARKING2 is indeed defined but not applied to that policy-map. There are two
    class-maps applied MARKING1 and class-default. Both will mark the traffic with MPLS EXP
    values.
    default:
    set mpls experimental imposition 0
    MARKING1
    set mpls experimental imposition 5
