多选题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？（）AThe 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 tagBNo 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 coreCTraffic 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 tagsDIP 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 offEMAC 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 layerFThe 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
多选题Your boss， Miss ，is interested in CEF. What should you tell her？ （）AThe FIB lookup is based on the Layer 3 destination address prefix （shortest match）.BThe adjacent table is derived from the ARP table.CThe FIB table is derived from the IP routing table.DWhen the adjacency table is full， a CEF TCAM table entry points to the Layer 3 engine to redirect the adjacency.ECEF IP destination prefixes are stored in the TCAM table， from the least specific to the most specific entry.FWhen the CEF TCAM table is full， packets are dropped.
