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

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

What are two differences between Class of Service (CoS) and Differentiated Services Code Point
(DSCP)? (Choose two.)

• A. DSCP defines priority levels and CoS manipulates traffic according to these defined priority levels.
• B. CoS defines priority levels and DSCP manipulates traffic according to these defined priority levels.
• C. DSCP operates at Layer 2 in OSI model, whereas CoS operates in Layer 3.
• D. CoS operates at Layer 2 in OSI model, whereas DSCP operates in Layer 3.
• E. DSCP is simpler and can scale easily as the network grows. CoS becomes more complex as network demand for prioritized data increase.
