HPE Aruba Certified Mobility Professional (ACMP) — Question 28

A company has a Unified Communications and Collaboration (UCC) solution.
✑ Users run softphones on their desktops and laptops.
✑ The UCC solution is configured to use a certain range of Layer 4 ports for VoIP traffic.
✑ The user devices connect to AOS-Switches.
A network administrator needs to configure the AOS-Switches to prioritize only the VoIP traffic. Where can the administrator configure a DSCP value to meet this goal?

Answer options

• A. in a global UDP port-based QoS policy
• B. on the interfaces through which the VoIP traffic is forwarded
• C. on the interfaces that connect to the user devices
• D. on the VLAN to which the user devices are assigned

Correct answer: B

Explanation

The correct answer is B because configuring the DSCP value on the interfaces that handle VoIP traffic allows for effective prioritization of that specific traffic. Options A and D are less direct since they either apply to a broader policy or at a VLAN level, which may not prioritize the traffic as effectively. Option C focuses on user device connections and does not directly influence the VoIP traffic prioritization.
