Users at the Charleville Company began experiencing high network delays when Internet connectivity was enabled for all users. After investigating the traffic flow, you determine that peerto-peer traffic from a music download site is consuming a large amount of bandwidth.

Use class-based WRED to randomly drop the peer-to-peer traffic during network congestions.C. Use class-based policing to limit the peer-to-peer traffic rate.D. Use class-based shaping to delay any excessive peer-to-peer traffic. Answer: C

考题
You work as a network technician. Your boss is interested in the QoS technology in the context ofvideo traffic. What can be said of application of this technology in this type of network？（）A、The access layer is the initial point at which traffic enters the network. Traffic is marked （orremarked） at Layers 2 and 3 by the access switch as it enters the network， or is "trusted" that it isentering the network with the appropriate tagB、No traffic marking occurs at the core layer. Layer 2/3 QoS tags are trusted from distributionlayer switches and used to prioritize and queue the traffic as it traverses the coreC、Traffic inbound from the access layer to the distribution layer can be trusted or reset dependingupon the ability of the access layer switches. Priority access into the core is provided based onLayer 3 QoS tagsD、IP precedence， DSCP， QoS group， IP address， and ingress interface are Layer 2 characteristics that are set by the access layer as it passes traffic to the distribution layer. Thedistribution layer， once it has made a switching decision to the core layer， strips these offE、MAC address， Multiprotocol Label Switching （MPLS）； the ATM cell loss priority （CLP） bit， theFrame Relay discard eligible （DE） bit， and ingress interface are established by the voicesubmodule （distribution layer） as traffic passes to the core layerF、The distribution layer inspects a frame to see if it has exceeded a predefined rate of trafficwithin a certain time frame， which is typically a fixed number internal to the switch. If a frame isdetermined to be in excess of the predefined rate limit， the CoS value can be marked up in a waythat results in the packet being dropped

考题
Which three practices are important to the implementation of a DiffServ QoS architecture？（）A、 Because services are allocated throughout the network before the transmission of data begins， traffic classes can be guaranteed QoS services.B、 Traffic classes are marked with Layer 2 markings to allow for more granularity in identifying traffic classes.C、 Traffic classes are marked with Layer 3 markings to allow them to traverse different network types without loss of QoS information.D、 Traffic classes allow networks to provide proper QoS treatment of packets without applications having to request services.E、 Based upon the network capabilities， QoS markings are placed on packets as needed throughout the network to allow for proper QoS treatment of packets.F、 QoS markings are placed on packets as close to the network edge as possible to allow distribution and core devices to determine QoS actions as quickly as possible.
考题
Which two statements are true about trust boundaries？（）A、Classifying and marking traffic should be done as close to the traffic source as possible. B、Classifying and marking traffic should be done at the distribution layer.C、Traffic is classified and marked as it travels through the network.D、If untrusted traffic enters a switch， it can be marked with a new QoS value appropriate for the policy in place.E、The trust boundary moves depending on the type of traffic entering the network.
考题
You need to determine where the trust boundaries will be in a new Company VOIP design. Which two statements are true about these trust boundaries？（）A、Trust boundaries are configured in the core of the network to provide the most efficient forwarding based upon QoS markings，B、Setting trust boundaries at the edge of the network allows intermediate hop devices to administer QoS policies without detailed packet identification.C、Trust boundaries are used to determine which QoS mechanism will be applied to the traffic. D、At the trust boundaries， the untrusted traffic will be marked with a new QoS value appropriate for the policy in place at the point where the traffic entered the campus network. E、Trust boundaries define the firewall rules for QoS admission into a network.
