You are the network administrator of an enterprise company that just deployed a global IP telephony environment. In order to guarantee good voice quality， you asked your provider to implement QoS on the CE routers of your MPLS network. On your LAN， you have also deployed QoS. Users， however， keep complaining about bad voice quality， and the provider does not see matches on the DSCP values that you have asked him to match upon. What is most likely the problem？（）
Which statement is true of a source that wants to transmit multicast traffic to group 239.1.1.1？（）
Two directly connected routers， R1 and R2， are both configured for OSPF graceful restart. R2 is able to switch packets in hardware， but R1 is not. If a network administrator logs on to R2 and performs a system reload， which will be the result？（）
For the following items，what is the mathematical relationship between the committed information rate （CIR）， committed burst （Bc）， and committed rate measurement interval （Tc）？（）
Which three statements are true about policing？ （）
