HPE6-A85 Exam - Topic 1 Question 17 Discussion

Actual exam question for HP's HPE6-A85 exam

Question #: 17
Topic #: 1

A network technician at a branch office is connecting VolP phones to a newly configured AOS-CX switch. Users are complaining that voice quality is not as good as at the corporate office. Further investigation

shows the local-priority value at the branch office is 1 while at the corporate office is 5.

What describes the issue regarding the default QoS behavior on the AOS-CX switch?

AThe QoS trust is set to DSCP by default, and the VolP phone's local-priority value is mapped to 1.

BThe QoS trust is set to CoS by default, and the VolP phone's local-priority value is mapped to 1.

CThe QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 1.

DThe QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 0.

Show Suggested Answer

Suggested Answer: C

In an AOS-CX switch, if the QoS trust mode is not configured, it is set to none by default. The VoIP phones will mark their traffic with a local-priority value, which, if the QoS trust mode is none, will correspond to CoS map entry 1 by default. The local-priority value of 1 at the branch office likely indicates that the traffic is not being prioritized correctly compared to the corporate office, where a local-priority of 5 suggests a higher level of prioritization for voice traffic.

I thought CoS was the default for VoIP setups, but maybe I'm wrong?

I think it's set to none by default, so that makes sense.

Wait, isn't the default QoS trust usually set to DSCP?

Totally agree, that low priority is hurting voice quality!

The local-priority value difference is key here.

I vaguely remember that if the local-priority is low, it could lead to poor voice quality. I just can't remember which option aligns with that.

I feel like the answer could be about the QoS trust being set to none, but I can't recall the specifics of the CoS mapping.

I think I practiced a similar question where the local-priority value affected voice quality. It might be related to how the switch handles QoS.

I remember something about QoS settings, but I'm not sure if the default trust is set to DSCP or CoS.

This seems straightforward to me. The key is understanding the default QoS trust setting on the AOS-CX switch and how that affects the mapping of the local-priority value. I think I can confidently select the correct answer.

I'm a bit confused by the technical details here. I'll need to review my notes on QoS and how it works on the AOS-CX switch. Maybe I can eliminate some of the options based on what I do know, and then make an educated guess.

Alright, I think I've got this. The question is asking about the default QoS behavior, so I need to focus on the default settings rather than any custom configurations. I'll need to carefully evaluate each answer option to determine which one best describes the issue.

Okay, let's see. The question mentions that the local-priority value is different between the branch office and the corporate office, so that must be the key issue. I'll need to consider the default QoS trust settings and how that affects the mapping of the local-priority value.

Hmm, this seems like a tricky one. I'll need to think carefully about the QoS behavior on the AOS-CX switch and how the local-priority value is mapped.

I'm pretty confident about this one. I know that INTERSECT returns the common rows between the two queries, so option C is definitely true.

I remember practicing questions on VoIP, and I think capacity could also be a factor, but that doesn't quite match the description here.

Hmm, I'm a bit unsure about this one. The options seem pretty similar - they all involve some kind of communication or reporting. I'll have to think this through carefully to make sure I don't miss anything.
