Which queuing mechanism should you configure to ensure voice traffic is always forwarded with the...

Quality of Service (QoS) on AOS-CX switches relies on hardware queues to manage congestion. Different traffic types require different handling logic.

Strict Priority (SP) Queuing: In an SP model, the switch services the highest-numbered queue (usually Queue 7 for Voice) until it is completely empty before it even considers sending a single packet from a lower-priority queue. This ensures that latency-sensitive traffic like Voice (VoIP) is never delayed by data bursts, providing the " highest priority " forwarding required by the prompt.

Weighted Fair Queuing (WFQ/DWRR): These methods (like Deficit Weighted Round Robin) assign a percentage of the bandwidth to each queue. While this prevents " queue starvation " for data traffic, it doesn ' t guarantee that voice will always go first; it just guarantees voice gets its " fair share. "

FIFO: This is the default " no-QoS " behavior where the first packet to arrive is the first to leave, regardless of its importance.

Virtual Output Queuing (VOQ): This is an internal architectural design of the switch fabric (often found in the 8000 series) used to prevent Head-of-Line (HOL) blocking across the switch backplane. It is not a configurable end-user queuing strategy for traffic prioritization.
