HPE7-A06 · Question #50
Refer to the exhibit. An end-to-end QoS design needs to be implemented for wired and wireless. What is needed on the LAN side to maintain the correct DSCP tags?
The correct answer is B. to trust all DSCP-marked packets in the QoS interior ports. In an end-to-end QoS design, the AP already maps WMM (wireless QoS) values to DSCP values when traffic enters the wired LAN. To preserve these QoS markings, the LAN edge and LAN core devices must be configured to trust the DSCP values instead of re-marking them. Trusting DSCP…

Explanation
In an end-to-end QoS design, the AP already maps WMM (wireless QoS) values to DSCP values when traffic enters the wired LAN. To preserve these QoS markings, the LAN edge and LAN core devices must be configured to trust the DSCP values instead of re-marking them. Trusting DSCP- marked packets ensures the QoS tags from the wireless side are carried consistently through the
