Explanation
QoS requirements (C) and traffic classification (E) must be identified first because they are foundational to all subsequent QoS decisions. You must first understand what performance guarantees voice traffic requires (latency, jitter, bandwidth) and then identify and classify all traffic types on the network before you can determine how to mark, police, or prioritize anything. QoS marking (A) and policing (B) are downstream actions that can only be configured after requirements and classification are defined. Data traffic usage (D) is a capacity planning concern, not a QoS design prerequisite.
