  1. Correct answer B.
    If it has the default settings, then switch-1 will strip the QOS value since trk1 isn’t manually configured to trust 802.1P values.

    If qos type of service was set, then it would automatically honor the 802.1P values.

    It will be C, as it is switched on the same VLAN. Therefore the switch honours the same 802.1P value…
