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. -
