I think - Policing - Marking - Queuing - Classification

I agree. I'm disappointed that the answers they have been chosen past 800 (where we pay to see more) have been the least accurate. I was feeling pretty good with the first set of questions, but now I'm feeling confused and second guessing everything when I see these questions. Then I see everyone is feeling the same. Not good...

given answers are incorrect applies a specific action to packets whenever the maximum rate of packets is exceeded == policing set the ToS value to associate a packet with a QoS group == marking reduces traffic congestion by holding packets and distributing them when the available bandwidth allows == queuing the overall process of using specific criteria to differentiate traffic into categories == classification

This is a weird question. Actually, it is shaping for 'reduces traffic congestion by holding packets and distributing them when the available bandwidth allows'. But there is no shaping in the question.

This is misleading. I am totally disappointed. We paid for this.

What is the purpose of classifying network traffic in QoS? A. configures traffic-matching rules on network devices B. services traffic according to its class C. identifies the type of traffic that will receive a particular treatment D. writes the class identifier of a packet to a dedicated field in the packet header
