Ruckus Certified Network Integrator (RCNI) — Question 25

Which command must be configured at the interface level to honor Differentiated Services Code Point (DSCP)-based Class of Service (CoS) on a ICX7750?

Answer options

• A. qos profile
• B. ip dscp-remark 1
• C. qos-tos map dscp-priority
• D. trust dscp

Correct answer: D

Explanation

The correct answer is D, 'trust dscp', as it configures the interface to recognize and prioritize packets based on their DSCP values. The other options either define QoS profiles, remark DSCP values, or map priorities without enabling the trust feature that allows the interface to honor the incoming DSCP markings.
