A network administrator is configuring QoS on vEdge 5000 router and needs to enable it on the transport side interface. Which policy setting must be selected to accomplish this goal?

Application policy is used for application-aware routing decisions such as path preference and SLA matching, not for enabling QoS on transport interfaces.

NetFlow is a traffic telemetry and flow-export feature for monitoring purposes, not a QoS configuration setting.

Cloud QoS Service side applies QoS policies to the service-side (LAN-facing) interfaces, not the transport-side interfaces.

Cloud QoS is the specific policy setting in Cisco SD-WAN that applies QoS shaping and scheduling to the transport-side (WAN) interface of a vEdge router. It allows administrators to define traffic classes and queue behaviors for traffic exiting toward the WAN transport, which is required when enabling QoS on the transport side of a vEdge 5000.
