Explanation

Common mistakes.

A. Application policy is used for application-aware routing decisions such as path preference and SLA matching, not for enabling QoS on transport interfaces.
B. NetFlow is a traffic telemetry and flow-export feature for monitoring purposes, not a QoS configuration setting.
C. Cloud QoS Service side applies QoS policies to the service-side (LAN-facing) interfaces, not the transport-side interfaces.
