A network engineer is configuring LLQ on a WAN edge router that must prioritize voice while guaranteeing minimum bandwidth to two data classes (business-critical and scavenger) during congestion. Voice is already placed in a strict-priority queue with the 'priority' command. For the business-critical and scavenger classes, the engineer wants each class to receive a proportional share of the bandwidth that remains after the priority queue is serviced, expressed as a percentage. Which command should be applied within those two class configurations in the policy map?
