单选题Choose the false statement concerning the use of CiscoWorks Internetwork Performance Monitor (IPM) in a Teleworker deployment.（）AIPM should not be run on a production network. BIPM helps verify if a Service Provider is meeting the Service Level Agreement. CIPM contains a database that can store data on latency, jitter, and drops of voice packets over a period of weeks or months.
