   A hospital connects its main campus to a remote clinic over a 50 Mbps MPLS link. The clinic runs an electronic health record (EHR) system, VoIP phones, and a backup service that transfers large files at night. During the day, the backup service occasionally runs and saturates the link, causing voice calls to drop. Which QoS strategy should be implemented?

   • AApply a shaper to VoIP traffic to limit its bandwidth usage
   • BMark VoIP as EF, EHR as AF, and backup as BE, then apply a policer to backup traffic
   • CMark all traffic as best effort and rely on the MPLS provider to prioritize
   • DMark backup as EF to ensure it completes quickly during the day
