第10题：

Which of the following statemets regarding Control Plane Policing （CoPP） is correct？（）

  • A、Control Plane Policing （CoPP） addresses the need to protect the management planes， ensuring routingstability， availability， and critical packet delivery.

  • C、Control Plane Policing （CoPP） uses a dedicated "control-plane" command via the Modular QoS CLI （MQC）to provide filtering and rate limiting capabilities.
  • D、Control Plane Policing （CoPP） uses "service policy" command under relevant interfaces to filter DOS packet to protect routing packets.
