Correct Answer: BE
Explanation/Reference:
Explanation:
This module discusses the types of queueing and queueing-related features (such as bandwidth management) which constitute the congestion management QoS features:
Class-based WFQ (CBWFQ): extends the standard WFQ functionality to provide support for userdefined traffic classes. For CBWFQ, you define traffic classes based on match criteria including protocols, access control lists (ACLs), and input interfaces. Packets satisfying the match criteria for a class constitute the traffic for that class. Priority queueing (PQ): With PQ, packets belonging to one priority class of traffic are sent before all lower priority traffic to ensure timely delivery of those packets.
