Explanation
Cisco vEdge routers perform Quality of Service (QoS) traffic classification on the ingress interface.
Common mistakes.
- A. While QoS policies can be associated with VPNs, the actual packet classification occurs at the interface level, not at the abstract VPN level.
- B. 'Per VEdge' is too general; QoS operations are specific to interfaces and applied policies.
- C. Egress interfaces are typically where queuing, shaping, and scheduling actions are performed based on the classification that occurred at the ingress interface.
