A. SAP-ingress
B. network-egress
C. FFPC
D. SAP-egress
正解：C
質問 2：

A. Best-effort
B. Self-generated
C. Real-time
D. Assured
正解：A
質問 3：
Click the exhibit button below.
All interfaces are using their default trust states and MPLS is used as the transport tunnel. The SAP-ingress, SAP-egress, and network QoS policies have been configured as shown below. Assume that the default network-queue policy is used on each router.
At router PE 1, customer traffic is arriving marked with DSCP BE and tagged with a dot1p value of 3.
Based on the configuration shown below for the VPRN service, what will be the DSCP and dot1p marking for the packet egressing at router PE 2? (Choose two)
A. The DSCP value will be set to af21.
B. The DSCP value will be set to be.
C. Thedot1pvaluewillbesetto2.
D. TheDSCPvaluewillbesettoaf23.
E. Thedot1pvaluewillbesetto5.
F. The DSCP value will be set to af 12.
G. The dot1p value will be set to 3.
正解：E,F
質問 4：
In which of the following scenarios is self-generated traffic QoS (sgt-QoS) useful?
A. The priority of various control packets requires special treatment throughout the network.
B. The BGP process is consuming too many CPU cycles and is impacting OSPF performance.
C. EXP markings on transit control traffic are not set correctly.
D. The priority of all self-generated traffic needs to be lowered to allow all other traffic to take precedence.
正解：A
質問 5：
Click the exhibit button below. A service provider has applied the SAP-ingress policy configuration below on his customer's SAP. The service provider notices that all of the customer's traffic is being dropped at the SAP-ingress. Which of the following actions can resolve the problem, if applied on its own? (Choose three)
A. Map AF traffic to queue 1
B. Set queue 3 to use priority mode.
C. Set the high-priority-only value to 0.
D. Set the traffic classification of packets to in-profile.
E. Set the CIR of queue 3 to a non-zero value corresponding to the customer's expected bandwidth requirements.
正解：A,C,D
質問 6：
A hierarchical scheduler policy with the shown parameters is configured at a service ingress. If the offered rate of each queue is 10Mbps, what is the operational PIR and CIR for queue 3?
