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.
