Selected Answer: B
https://en.wikipedia.org/wiki/Low-latency_queuing Low-latency queuing (LLQ) is a feature developed by Cisco to bring strict priority queuing (PQ) to class-based weighted fair queuing (CBWFQ). LLQ allows delay-sensitive data (such as voice) to be given preferential treatment over other traffic by letting the data to be dequeued and sent first.
