QUESTION: 38

IN QOS DESIGN, THE DESCRIPTION OF THE DESIGN PRINCIPLES OF TRAFFIC SCHEDULING IS INCORRECT ()

LPQ/WFQ scheduling strategies can be used to avoid low-priority services not being able to obtain bandwidth resources
The current QoS policy needs to take into account the subsequent expansion of the network
Core services and video-voice services should ensure the absolute priority of forwarding and use PQ scheduling
Unless the business has special requirements, some parameters of the scheduling policy should be defaulted as much as possible
