QUESTION 99
In what three ways is QoS applied in the campus network? (Choose three.)
A. No traffic marking occurs at the core layer. Layer 2/3 QoS tags are trusted from distribution layer switches and used to prioritize and queue the traffic as it traverses the core.
B. 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.
D. The distribution layer inspects a frame to see if it has exceeded a predefined rate of traffic within a certain time frame, which is typically a fixed number internal to the switch. 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.
