单项选择题Refer to the exhibit. You have noticed that several users in the network are consuming a great deal of bandwidth for the peer-to-peer application Kazaa2. You would like to limit this traffic， and at the same time provide a guaranteed 100 kb s bandwidth for one of your servers. After applying the configuration in the exhibit， you notice no change in the bandwidth utilization on the serial link； it is still heavily oversubscribing the interface. What is the cause of this problem？（）

A.CEF needs to be enabled for NBAR
B.In class Kazaa2， you should configure a policer instead of a drop command.
C.The server class should have a priority of 100.
D.The bandwidth parameter on serial 0/0 is wrong.
E.Kazaa2 is not a valid protocol.
