Discuss Nokia 4A0-C02 Exam Topic 4 Question 62

When allocating scheduling resources, which of the following statements BEST describes how the egress port scheduler allocates bandwidth?

AThe egress port scheduler takes the ratio of requested bandwidth to total bandwidth request from all children. It allocates bandwidth fairly, using these percentages and not exceeding the egress interface speed.

BThe egress port scheduler allocates bandwidth based on a WRR distribution method that takes into account the CIR and PIR requested at each level and the max speed, either default or configured, on egress.

CThe egress port scheduler allocates bandwidth on a first come, first served distribution method that takes into account the total CIR and PIR requested at each level and the max PIR requested from a single level.

DThe egress port scheduler will limit the bandwidth offered to the egress port based on the over-subscription factor, provisioned under the router interface, while using a WRR scheduler for the remaining bandwidth.

EThe egress port scheduler will use the Russian Dolls Method to allocate bandwidth to each level of requested bandwidth. HPO-Only is automatically set to 100%, allowing only high priority traffic to be buffered during congestion.

D definitely covers the over-subscription factor well.

Wait, Russian Dolls Method? That’s new to me!

C sounds too simplistic for modern networks.

I think B makes more sense with WRR in play.

A is spot on, fair allocation is key!

I feel like option A is too simplistic. It doesn’t seem to account for the complexities of bandwidth requests like the others do.

I’m a bit confused about the Russian Dolls Method mentioned in option E. I don’t recall that being covered in depth.

I think option B sounds familiar since we practiced a question about bandwidth allocation using CIR and PIR.

I remember studying the different scheduling methods, but I'm not entirely sure if WRR is the best choice here.

Okay, I've got an idea. I think the user needs to set up their profile first before they can request software through the portal.

I'm confident I can nail this one. The key is to identify the option that best aligns with the stated benefits of self-service.

I feel pretty confident about this one. Nonmaleficence is all about not harming patients, so C is the clear choice here. The other options are important ethical principles, but they don't directly address the core idea of avoiding harm.

I'm feeling a little unsure about this one. There are a few different moving parts with the web roles, entity permissions, and managing the free courses. I'll need to re-read the question a few times to make sure I understand it fully before deciding on an answer.
