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 tag B . 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 core C . 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 tags D . 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 off E . 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 layer F . 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

A .  The Cisco Aironet AP handles real-time portions of the LWAPP protocol， and the WLAN  controller handles those items which are not time sensitive.

C .  Virtual MAC architecture allows the splitting of the 802.11 protocol between the Cisco Aironet  AP and a LAN switch. D .  A Cisco Aironet solution includes intelligent Cisco Aironet access point （APs） and Cisco  Catalyst switches. E .  In the Cisco Aironet solution， each AP is locally configured by the use of either a web interface  or the command line interface.

A .  LWAPP is a proprietary protocol， and because of its very high overhead it is not widely adopted. B .  Control traffic is encapsulated in UDP packets with a source port of 1024 and a destination port  of 12223. C .  Layer 3 LWAPP is a UDP/IP Frame that requires a Cisco Aironet AP to obtain an IP address  using DHCP. D .  Data traffic is encapsulated in UDP packets with a source port of 1024 and a destination port of  12223. E .  Control traffic is encapsulated in TCP packets with a source port of 1024 and a destination port  of 12223.
