A network administrator is deploying QoS with the ability to provide a special queue for voice traffic so that voice traffic is forwarded before network traffic in other queues. Which queuing method would be the best choice?
A. FIFO
B. WFQ
C. LLQ
D. CBWFQ
Low Latency Queueing (LLQ) allows delay-sensitive data, such as voice traffic, to be defined in a strict priority queue (PQ). This allows it to always be sent first before any packets in any other queue are forwarded.
