Discuss Cisco 350-501 Exam Topic 4 Question 126

Refer to the exhibit:

Which statement supports QPPB implementation?

AQoS policies are identified in the MPLS forwarding table

BQoS policies rely exclusively on BGP attributes to manipulate traffic

CQoS policies use BGP to gain full coverage on the network.

DQPPB policies affect only egress traffic

Suggested Answer: C

QPPB (QoS Policy Propagation via BGP) is a mechanism that allows the application of QoS policies using IP precedence or QoS group settings based on BGP community lists, AS paths, and prefix lists. In the context of the exhibit provided, it's clear that QPPB is being used to apply a specific QoS policy (qos-group 10) based on AS path attributes. This aligns with option C, as it indicates that QoS policies are utilizing BGP to achieve comprehensive network coverage.

Overall, C covers the most ground. I feel confident about it.

D is misleading. QPPB affects more than just egress.

Paulina 2 months ago

But B seems too limiting. Relying only on BGP?

Lindsey 2 months ago

A is interesting too. It connects QoS with MPLS.

Charisse 2 months ago

Agreed! C makes sense for QPPB implementation.

Viki 2 months ago

I think C is the best choice. It shows full network coverage.

Isadora 3 months ago

D) only affecting egress? That seems too limited for QPPB.

Loren 3 months ago

Wait, are we sure about C)? Sounds a bit off to me.

Eun 3 months ago

B) can't be right, BGP alone doesn't handle QoS like that.

Raelene 3 months ago

Totally agree, A) makes the most sense here!

Paris 3 months ago

A) is the right choice, QoS policies are in the MPLS table.

Kris 3 months ago

A) is a fact, but it’s not the whole picture.

Phuong 4 months ago

Wait, I thought QPPB only affected egress traffic?

Sharee 4 months ago

C) is the best option here, no doubt!

Leontine 5 months ago

I disagree, B) makes more sense for QPPB.

Helga 6 months ago

A) is definitely the right choice.

Makeda 6 months ago

I vaguely recall that QPPB affects egress traffic, but does that mean option D is the best answer? I’m not entirely sure.

Ernest 6 months ago

I’m a bit confused about the role of QoS policies in the MPLS table. Does that mean option A could be relevant?

Gabriele 6 months ago

I feel like I've seen a similar question before, and I think it was about how QoS interacts with BGP. Maybe option C is the right choice?

Reena 7 months ago

I think I remember that QPPB is about managing traffic, but I'm not sure which option really supports its implementation.
