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A new lightweight access point （LAP） has been installed in the Company WLAN. Which two statements correctly describe the association process between this LAP and a WLAN controller？ （）AAn access point will search for a controller using a broadcast address if using LWAPP Layer 2 and a unicast address if using LWAPP Layer 3 mode.BIf multiple wireless controllers are detected by an access point， the controller with the fewest associated access points is chosen to associate with.CIn order to associate in Layer 3 mode， the access point must have been preconfigured with an IP address.DOnce an access point associates with a controller in LWAPP Layer 3 mode， it receives an IP address from the controller.EAn access point first searches for a controller in LWAPP Layer 2 mode. If the search is not successful， the access point then attempts to locate a controller in LWAPP Layer 3 mode.FIf multiple wireless controllers are detected by an access point， all of them will be used and traffic will be load balanced.
