Question #41

In which of the following scenarios is the egress port scheduler useful? (Choose two)

A . A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress.
B . A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are being dropped on ingress.
C . A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps.
D . An equipment manufacturer has requested a NULL epipe service that will transparently pass dot1Q between the new location and national headquarters.

Question #42

Policing improves bandwidth utilization by using buffering to absorb high bursts of traffic.

Question #43

On the Nokia 7750 SR, which of the following QoS-related policies can be configured on a SAP? (Choose three)

Question #44

Which of the following statements BEST describes where shaping mechanisms should be applied?

A . On all ports on the Nokia 7750 SR.
B . At the junction of high-speed to low-speed links or at places of traffic aggregation.
C . At the junction of low-speed to high-speed links or at places of traffic aggregation.
D . On low-speed WAN links.
E . Nowhere. Shaping is only performed in hardware and serviced in a round-robin.

Question #45

When using an egress port scheduler, on which scheduling loop are orphaned queues serviced?

Question #46

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.

Question #47

Traffic assigned to forwarding classes is placed into queues, while the contents of the queues are serviced in a controlled manner using____________.

Question #48

To implement Hierarchical-QoS (Multi-tiered scheduling), which of the following actions must be undertaken? (Choose three)

A . H-QoS capabilities must be enabled globally on the router
B . A scheduler-policy must be configured.
C . The queues in the SAP-ingress and SAP-egress policies do not require additional configuration attributes to make use of the hierarchical schedulers.
D . The network queue policy must be configured to make use of the scheduler-policy.
E . The scheduler-policy must be referenced in the SAP-ingress and SAP-egress policies.
F . The scheduler-policy must be applied on the service SAP.

Question #49

Which of the following statements regarding policing and shaping on the Nokia 7750 SR are TRUE? (Choose two)

A . The larger the configured MBS value, the lower the amount of shaping performed.
B . When policing is enabled on the SAP-ingress, all traffic is considered as in-profile.
C . Setting the CIR to 1000 and the PIR to max will enable shapeless policing at 1 Mbps within the SAP-egress policy.
D . Configuring MBS to equal CBS will disable shaping.
E . Setting the CIR and PIR to equal values disables soft-policing.

Question #50

Click the exhibit button below.

Given this scheduler-policy configuration, which of the following can be said about the scheduler called "high"? (Choose two)

A . It is a parent scheduler.
B . It is the top-level scheduler.
C . It can allocate up to 50 Mbps of bandwidth to scheduler "low" since the bandwidth is not used by another Tier 3 scheduler.
D . It is a child scheduler.
E . It can only have queues as children.
