Question No : 9
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.
