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. The distribution layer, once it has made a switching decision to the core layer, strips these off. C. MAC address, Multiprotocol Label Switching (MPLS), the ATM cell loss priority (CLP) bit, the Frame Relay discard eligible (DE) bit, and ingress interface are established by the voice submodule (distribution layer) as traffic passes to the core layer.

If a frame is determined to be in excess of the predefined rate limit, the CoS value can be marked up in a way that results in the packet being dropped. E. The access layer is the initial point at which traffic enters the network. Traffic is marked (or remarked) at Layers 2 and 3 by the access switch as it enters the network, or is "trusted" that it is entering the network with the appropriate tag. F. Traffic inbound from the access layer to the distribution layer can be trusted or reset depending upon the ability of the access layer switches. Priority access into the core is provided based on Layer 3 QoS tags. Answer: AEF 21. Which two Aironet enterprise solution statements are true? (Choose two.) A.

PassGuide 642-892


B: A switch is not concerned about its local configuration of the STP timers values. It will only consider the value of the STP timers contained in the BPDU it is receiving. C: To successfully exchange BPDUs between two switches, their STP timers value (hello, forward delay, max age) must be the same. D: If any STP timer value (hello, forward delay, max age) needs to be changed, it should at least be changed on the root bridge and backup root bridge. E: On a switched network with a small network diameter, the STP hello timer can be tuned to a lower value to decrease the load on the switch CPU. F: The root bridge passes the timer information in BPDUs to all routers in the Layer 3 configuration. Answer: ABD 253. Which two statements are true about HSRP, VRRP, and GLBP? (Choose two.) A.
