The correct answer is C. The QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS. 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…
Question
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?
Options
- 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
- DThe QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS

Explanation
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.
