Totally with you, Jeanice! D makes the most sense here.

Wait, how can PIR be 10Mbps with that ingress rate? Sounds off.

I’m leaning towards A, but I’m not sure about the CIR.

No way, it’s definitely C, PIR = 10Mbps!

I vaguely recall that the best-effort traffic gets a portion of the total bandwidth, but I can't remember the exact numbers. I might need to guess between A and C.

I feel like the CIR is usually a fixed value, but the PIR can vary based on the total ingress. I’m leaning towards option D, but I’m not entirely confident.

I remember something about how best-effort traffic is allocated bandwidth based on the ingress rate, but I'm not sure how to apply that here.

I think I practiced a similar question where the ingress rate was different, and it had a clear formula for calculating PIR and CIR. I hope I can recall that now.

Hey, did you guys see the latest meme about network administrators? Apparently, they can fix any problem by rebooting the router. Hilarious, right? Anyway, back to the question at hand...

This is easy, folks. The scheduler-policy clearly states the percentages, so the answer has to be D. Although, I do wonder if the exam writer has a twisted sense of humor and will mark E as the correct answer, just to keep us on our toes.

Hmm, I'm going with B. Gotta keep it simple, you know? 1Mbps for both PIR and CIR, that's the safe bet.

I see your point, but I still think E is the best answer. PIR and CIR both at 1.25Mbps.

Wait, are we sure this isn't a trick question? I bet the answer is C, just to mess with us. 10Mbps PIR? Sounds too good to be true!

Let's see, the correct answer is actually D. The PIR is 5Mbps and the CIR is 1.25Mbps.

I think you might be onto something, but I'm leaning towards D. The PIR and CIR values seem more balanced.

I think the answer is D. The scheduler-policy shows that the best-effort traffic has a PIR of 50% of the total bandwidth, which is 10Mbps. So the PIR should be 5Mbps, and the CIR is 25% of that, which is 1.25Mbps.
