HP Exam HPE6-A85 Topic 7 Question 19 Discussion

Actual exam question for HP's HPE6-A85 exam

Question #: 19
Topic #: 7

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 wonder if the corporate office is using some kind of secret VoIP sorcery to get that sweet, sweet voice quality. Must be the local-priority setting!

Haha, I bet the network technician is wishing they had a magic 'fix voice quality' button on the switch. Option B it is!

I'm still a bit confused about the QoS trust settings on the AOS-CX switch. Isn't it supposed to be DSCP by default? *scratches head*

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

A: Maybe adjusting the local-priority value at the branch office to match the corporate office could improve the voice quality.

B: That's correct. The issue might be with the local-priority value at the branch office being lower than at the corporate office.

Hmm, I was thinking it might be option D, since the QoS trust is set to none by default, and the VoIP phone's local priority is configured for CoS map entry 0. But B makes more sense.
