HP Exam HPE6-A85 Topic 1 Question 17 Discussion

Actual exam question for HP's HPE6-A85 exam
Question #: 17
Topic #: 1
[All HPE6-A85 Questions]

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?

Show Suggested Answer Hide 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.

Yeah, QoS settings can mess up voice quality. I'm sticking with B too. It's most logical considering the context.

No, I think option B is more accurate. CoS mapping directly affects the local-priority value which matches the problem description.

I agree, Carol. CoS mapping could be the key. But what about option A? DSCP trust setting could also align with the issue.

Exactly! Answer B makes sense. It says the QoS trust is set to CoS by default, and the VolP phone's priority is mapped to 1.

I think it's related to the QoS settings on those AOS-CX switches.

This question is tough! Why is the voice quality different at the branch office?
