H31-161 Question #136: Real Exam Question with Answer & Explanation

The inner VLAN tag in layer 2 user packets is used to differentiated key services from other services. If packets are not processed after being encapsulated by QinQ, the 802. 1p information of the inner VLAN tag becomes invalid. After the QinQ is employed, three methods can be used to configure conditions for sensing 8021p configuration of the inner VLAN tag: 1. Reset the 802.1p of the outer VLAN tag regardless of the existing 02 1p configurations of the inner VLAN tag. 2. Automatically swap the 802. 1p configurations of the inner VLAN tag to that of the outer VLAN tag. 3. Reset the 802.1p configurations of the outer VLAN tag based on the existing 802.1p configurations of the different VLAN tags
