Which two application requirements are mandatory for traffic to receive proper treatment when placed in...

The priority queue (strict priority queue) is intended for real-time, delay-sensitive traffic like voice and certain video, which have:

D. Intolerance to jitter: Real-time traffic requires consistent latency.

E. TCP-based application: Many real-time video streams and some financial trading apps use TCP but still require minimal jitter and latency.

CCDE v3.1 emphasizes that strict priority queue should only be used for traffic highly sensitive to delay and jitter to avoid starving other queues.

Why other options are incorrect:

A: HTTP-like small transactions are delay-tolerant.

B: WRED (Weighted Random Early Detection) is used for congestion avoidance, not prioritization.

C: Priority queue is specifically for traffic intolerant to loss and jitter.
