Question 73

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

H-QoS capabilities must be enabled globally on the router

A scheduler-policy must be configured.

The queues in the SAP-ingress and SAP-egress policies do not require additional configuration attributes to make use of the hierarchical schedulers.

The network queue policy must be configured to make use of the scheduler-policy.

The scheduler-policy must be referenced in the SAP-ingress and SAP-egress policies.

The scheduler-policy must be applied on the service SAP.

Question 74

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

The larger the configured MBS value, the lower the amount of shaping performed.

When policing is enabled on the SAP-ingress, all traffic is considered as in-profile.

Setting the CIR to 1000 and the PIR to max will enable shapeless policing at 1 Mbps within the SAP-egress policy.

Configuring MBS to equal CBS will disable shaping.

Setting the CIR and PIR to equal values disables soft-policing.

Question 75

Click the exhibit button below. Given this scheduler-policy configuration, which of the following can be said about the scheduler called 'high'? (Choose two)

It is a parent scheduler.

It is the top-level scheduler.

It can allocate up to 50 Mbps of bandwidth to scheduler 'low' since the bandwidth is not used by another Tier 3 scheduler.

It is a child scheduler.

It can only have queues as children.

Question 77

Which of the following statements regarding egress FC and profile over-ride are TRUE? (Choose two)

Packets can be classified into 16 different FCs when using priority mode queuing.

This feature is available on egress SAPs within any service.

MPLS EXP bits can be changed based on multi-field classification.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, the BA classification can override the forwarding class while the MF classification can override the profile.
