Nokia 4A0-C02 Exam - Topic 10 Question 9 Discussion

Actual exam question for Nokia's 4A0-C02 exam

Question #: 9
Topic #: 10

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

AWhen 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.

BWhen 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.

CThe greater the difference between PIR and CIR rates in a queue, the less likely a CIR will be provided.

DPackets 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.

EWhen 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.

E is misleading, I don’t agree with that.

I recall that high-priority queues can lead to delays, but I’m not entirely certain about the trade-off between packet loss and delay.

I’m a bit confused about the difference between PIR and CIR rates; I feel like I read something that suggests a greater difference could affect CIR provision.

I think option B sounds familiar from our practice questions, especially regarding egress bandwidth and forwarding classes.

I remember something about profile-mode queues, but I'm not sure if they maintain the in-profile status at egress.

Partner Central sounds like the most relevant template based on the description. I'll make sure to double-check the details, but that's my initial impression.

Okay, let's think this through step-by-step. The key seems to be that the two APs involved in the roaming process need to have certain things in common.

This is a good opportunity to apply my knowledge of network security and access control. I've got a strategy for working through this.
