QUESTION 20
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.

QUESTION 2
Client 1 is able to ping 209.65.200.226 but not the Web Server at 209.65.200.241. Initial troubleshooting
shows and R1 does not have any BGP routes. R1 also does not show any active BGP neighbor.
In the above ticket R1 and all others are able to ping 209.65.200.226 but not the Web Server only. This is
because R1 is directly connected to 209.65.200.226 and BGP is not required in order to ping directly
connected network and as soon as R1 knows about 209.65.200.224 network all other devices are also
able to ping 209.65.200.226, since they are coming to R1 for any unknown route, because of default route
propagate through R1′s OSPF (using ‘default-information originate always’ command). However Web
Server is not accessible until BGP configured properly between R1 and ISP(209.65.200.226) because only
then R1 will receive the information about Web Server’s network.
Following are the symptoms of above ticket:
1- No one is able to ping Web Server.
2- Client 1 and all others can ping upto 209.65.200.226.
3- ‘sh ip route BGP’, you will not see any BGP route.
4- ‘sh ip bgp neighbor’ on R1, you will not see any active BGP neighbor.

In this scenario you need to check bgp neighbotship “show ip bgp sum”.
The neighbor`s address in the neighbor command is wrong under router BGP (use ipv4 Layer 3).
You need to delete the wrong neighbor statement and enter the correct neighbor address in the neighbor
command (change 209.56.200.226 to 209.65.200.226).
