Hmm, I'm not sure about C. Doesn't the question say the queues need additional configuration? Anyway, A, B, and E are definitely the right choices.

A, B, and E are the correct answers. The question clearly states that 3 actions must be undertaken, and those 3 cover the necessary steps.

I believe E is important since the scheduler-policy needs to be referenced in both SAP-ingress and SAP-egress policies, but I'm not 100% sure about the others.

I'm not entirely sure, but I feel like we had a practice question that mentioned configuring a scheduler-policy. Maybe B is correct?

I remember that enabling H-QoS globally is usually a first step, so I think A is definitely one of the answers.

I'm a little unsure about this one. There are a lot of technical terms and concepts that I'm not super familiar with. I think I'll need to review my notes on hierarchical QoS before I can confidently answer this question. Maybe I'll start by identifying the options that seem the most essential and go from there.

Okay, let's see. I know that hierarchical QoS involves multiple levels of scheduling, so I'm guessing the options related to configuring scheduler policies and applying them to different parts of the network are going to be important. I'll focus on those and try to eliminate the ones that don't seem essential.

I agree with John. The question is straightforward, and those 3 options are the ones required to implement Hierarchical-QoS.

This looks straightforward enough. I'd say the key things are enabling H-QoS globally, configuring a scheduler policy, and then applying that policy to the relevant SAP-ingress and SAP-egress policies. The other options seem like they might be nice-to-haves, but the core actions are those three.

Hmm, this seems like a pretty technical question. I'm not super familiar with hierarchical QoS, so I'll need to think through the options carefully. Maybe I'll start by looking up the definition of hierarchical QoS to get a better understanding of the concepts involved.

I think the key here is to focus on the actions that must be undertaken, as the question asks. I'd start by looking at the options that mention "must" or "required" to get a sense of the essential steps.
