HPE Aruba Certified Mobility Professional (ACMP) — Question 38

An AOS-Switch has type of service disabled on it globally. The administrator enters:
AOS-Switch(config)# interface 1 qos trust device aruba-ap
What is the effect of this command?

Answer options

• A. if the AOS-Switch is integrated with an Aruba Mobility Controller, it uses QoS settings sent by the controller to prioritize traffic sent on interface 1
• B. if interface 1 connects to an Aruba AP, it uses the incoming DSCP and a global DSCP map to prioritize traffic received on this interface
• C. if the AOS-Switch is integrated with an Aruba Mobility Controller, it uses QoS settings sent by the controller to classify traffic received on interface 1
• D. if interface 1 connects to an Aruba AP, the switch marks all traffic received on the interface with a higher than default priority value

Correct answer: A

Explanation

The command configures the AOS-Switch to use QoS settings from an Aruba Mobility Controller, allowing it to prioritize outgoing traffic on interface 1. Options B and D refer to incoming traffic processing, which isn't relevant here, while option C incorrectly states that the settings classify traffic instead of prioritizing it.
