Selected Answer: D
A. qos profile Used to apply a predefined QoS profile, but does not enable trusting DSCP markings. B. ip dscp-remark 1 This is used to set or remark DSCP values on outbound traffic — not to trust inbound values. C. qos-tos map dscp-priority Used to map DSCP to internal priorities, but without trust dscp, the switch won't use DSCP from the incoming packets.
