Alcatel-Lucent NRS II – IP/MPLS Services — Question 3

In the context of hierarchical scheduling, a scheduler is configured with a CIR weight of 0. Which of the following statements is TRUE?

Answer options

• A. The scheduler will be allocated its "within CIR" bandwidth before all other children at the same level have received their "within CIR" bandwidth.
• B. The scheduler will be allocated its "within CIR" bandwidth after all other children at the same level have received their "within CIR" bandwidth.
• C. The scheduler will be allocated its "within CIR" bandwidth after all other children at all levels have received their "within CIR" bandwidth.
• D. The scheduler will not be allocated its "within CIR" bandwidth.

Correct answer: D

Explanation

The correct answer is D because a CIR weight of 0 means the scheduler is not entitled to any 'within CIR' bandwidth allocation. The other options incorrectly suggest that the scheduler can still receive bandwidth in various scenarios, which is not possible with a weight of 0.
