• Question 188:

  Which of the following statements about CIR of a queue is TRUE?

  A. It may exceed PIR of the queue.
  B. It may be exceeded by the average servicing rate of the queue.

• Question 189:

  Which of the following statements regarding scheduling on the Nokia 7750 SR is TRUE? (Choose two)

  A. When using profile-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will still be considered as in-profile at egress.
  B. When an HQoS strategy using an egress port-scheduler has been deployed, Tier 1 receives its scheduling rates based on the amount of egress bandwidth available for each forwarding class.
  C. The greater the difference between PIR and CIR rates in a queue, the less likely a CIR will be provided.
  D. Packets scheduled out of high-priority queues in the default scheduler will have a lower chance of packet loss at the expense of incurring a higher probability of delay.
  E. When using priority-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will be considered as in-profile at egress.
