多项选择题Refer to the exhibit. A customer indicates their teleworkers plan to use IP phones in their home offices. The IT department has surveyed the planned teleworkers, resulting in the user groupings shown in the exhibit. To provide the highest voice quality, the best recommendations to this customer are（）.

A.Deploy all three groups with a QoS service policy, choosing the parameters for Traffic Shaping based on the average uplink speed across the three groups. 
B.Teleworkers in Groups A and B should inquire with their DSL providers for subscriptions with higher uplink bandwidths. 
C.Teleworkers in Group C should change their subscriptions to DSL for deployment consistency.
D.Teleworkers in Group A should upgrade their subscription to obtain static IP addresses
