单选题Which statement is true about the Call Admission Control （CAC） feature in VoIP networks？（）A
CAC is used to allocate enough bandwidth for the number of calls that are allowed on the VoIP network.B
CAC is used to protect the quality of the voice calls by preventing call establishment if enough resources are not available on the network.C
CAC provides queuing mechanisms for voice calls if the packets exceed the configured or budgeted rate.D
In a VoIP network the CAC can be replaced with the LLQ QoS mechanism if it has been properly implemented.

单选题Choose the false statement concerning the use of CiscoWorks Internetwork Performance Monitor (IPM) in a Teleworker deployment.（）A
IPM should not be run on a production network. B
IPM helps verify if a Service Provider is meeting the Service Level Agreement. C
IPM contains a database that can store data on latency, jitter, and drops of voice packets over a period of weeks or months. D
The QoS service policy should contain an allocation of sufficient bandwidth in the priority queue (LLQ) for both the SAA probe simulating a voice call and the voice call. If not, voice quality will suffer.
