HPE Aruba Certified Mobility Professional (ACMP) — Question 64

A network administrator needs to configure an AOS-Switch to classify traffic. Comparing QoS policy and global policy, what is one function that only a class-based
QoS policy can fulfill?

Answer options

• A. Apply a DSCP to HTTP traffic from some sources but not other sources.
• B. Apply a DSCP rather than an 802.1p value to classified traffic.
• C. Override the incoming DSCP in the received traffic.
• D. Override the DSCP or priority applied directly to an interface.

Correct answer: B

Explanation

The correct answer is B because class-based QoS policies specifically allow for the application of a DSCP to traffic rather than using an 802.1p value, which is not a function of global policies. The other options either describe capabilities that can be fulfilled by both policy types or do not align with the unique features of class-based QoS.
