Nokia 4A0-107 Exam - Topic 10 Question 71 Discussion

Actual exam question for Nokia's 4A0-107 exam

Question #: 71
Topic #: 10

Refer to the exhibit.

Given the scheduler-policy parameters shown, and assuming the offered rate of each queue is 10 Mbps, what are the operational PIR and CIR for queue 3?

APIR = 4 Mbps, CIR = 1 Mbps

BPIR = 1 Mbps, CIR = 1 Mbps

CPIR = 10 Mbps, CIR = 1 Mbps

DPIR = 5 Mbps, CIR = 1.25 Mbps

EPIR = 1.25 Mbps, CIR = 1.25 Mbps

Wait, how can PIR be lower than the offered rate?

I think it's actually C, not D.

PIR = 5 Mbps, CIR = 1.25 Mbps is the right choice!

I feel like I saw a question where the PIR was 4 Mbps, but I can't remember if that was for queue 2 or 3. This is confusing!

I practiced a similar question where the CIR was 1 Mbps, so I’m leaning towards options that have that value.

I remember something about how the CIR is often lower than the PIR, but I can't recall the exact values for queue 3. This is tricky!

I think the PIR is usually the peak rate, so maybe it could be 10 Mbps for queue 3? But I'm not sure about the CIR.

Okay, I've got this. I just need to carefully read through the scheduler-policy parameters and do the math to find the PIR and CIR for queue 3. I'm confident I can get the right answer.

I've seen similar questions before, so I think I know the approach. I'll need to apply the scheduler-policy rules to the offered rate to determine the PIR and CIR for queue 3.

I'm a bit confused by the terminology here. What exactly are PIR and CIR, and how do I use the information provided to calculate them for queue 3?

Okay, let me think this through step-by-step. The offered rate for each queue is 10 Mbps, and the scheduler-policy parameters are given. I should be able to work this out.

Hmm, this looks like a tricky one. I'll need to carefully review the scheduler-policy parameters and the offered rate to figure out the PIR and CIR for queue 3.
