Given the SAP-ingress policy, to which forwarding class is the traffic matched?
- A . AF
- B . EF
- C . H2
- D . H1
- E . BE

- A . Policing, expedited
- B . Metering, marked discard eligible
- C . Marking, marked discard eligible
- D . Policing, discarded
- E . Shaping, discarded
Based on queue usage, which of the following QoS-policies when combined will allow queue rates to be dynamically allocated? (Choose two)
- A . The slope-policy
- B . The SAP-ingress policy
- C . The network-queue policy
- D . The scheduler-policy
- E . The network-policy
- F . The WRED-policy
- G . The arbitrator-policy
Which of the following statements regarding the egress port scheduler is TRUE?
- A . The egress port scheduler can have up to 17 children spread across 8 levels.
- B . Multiple egress port schedulers can be assigned to a single port with many HQoS children.
- C . Multiple HQoS policies can be children of a single port scheduler.
- D . Multiple egress port schedulers can be children of a single HQoS scheduler.
Which of the following can be used as classifiers of customer traffic? (Choose three)
- A . DSCP value
- B . 802.1p value
- C . IP DF bit
- D . TCP/UDP port numbers
- E . HTML version number
Which of the following statements are TRUE when discussing self-generated traffic QoS? (Choose two)
- A . In order to mark Layer 2 traffic, sgt-qos will set various ToS bits.
- B . DSCP bits can be set per application, per routing instance.
- C . The DSCP marking stays nc1 for all applications. Only the internal FC is manipulated across different applications.
- D . In order to mark Layer 2 self-generated traffic, network interfaces must be set to dot1Q.
- E . The internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.

Given that the slope-policy (below) has been enabled and applied on a network port, which of the following statements are TRUE? (Choose three)
- A . All out-of-profile traffic will be dropped before any in-profile is dropped.
- B . The time average factor of 0 will discard all packets arriving in the shared buffer pool.
- C . When the shared buffer utilization reaches 51%, in-profile packets might be dropped.
- D . The highest probability with which an out-of-profile packet can be dropped is 20%.
- E . When an in-profile packet arrives and the shared buffer utilization is at 69%, the packet will have approximately a 60% likelihood of being discarded.
