Selected Answer: B

Answer: B. Configuring QoS rules at the internet router to prioritize the VoIP calls By implementing Quality of Service (QoS) on the existing network equipment, you can ensure voice traffic is given higher priority than other applications (such as the new document management system). This approach should mitigate audio issues without requiring expensive new links or hardware.
