Alcatel-Lucent NRS II – IP/MPLS Services — Question 5

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

Answer options

• 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.

Correct answer: B, E, F

Explanation

The correct actions to implement Hierarchical-QoS include configuring a scheduler policy (B), referencing it in the SAP-ingress and SAP-egress policies (E), and applying it on the service SAP (F). Options A, C, and D are incorrect because they either misstate requirements or pertain to unrelated configuration aspects of QoS.
