Which two application requirements are mandatory tor traffic to receive proper treatment when placed in the priority queue? (Choose two.)

Small, consistent transactions (similar to fixed-size voice packets) are required so that the priority queue does not starve other queues by monopolizing bandwidth - the policer on the priority queue depends on predictable, low-volume bursts to function correctly.

WRED (Weighted Random Early Detection) is a congestion avoidance mechanism applied to non-priority queues; traffic in the strict priority queue is never subject to WRED drops.

Traffic in the priority queue should be intolerant to packet loss, not tolerant - loss-tolerant traffic does not require the special treatment of strict priority scheduling and should be placed in lower queues.

Intolerance to jitter is the defining requirement for priority queue placement, because LLQ provides strict priority scheduling that services the PQ before all other queues, minimizing queuing delay and delay variation for real-time applications such as VoIP.

TCP-based applications are poor candidates for the priority queue because TCP retransmission, windowing, and slow-start mechanisms interact poorly with strict priority scheduling; UDP real-time traffic such as VoIP is the intended use case.
