What is a characteristic of video traffic that governs QoS requirements for video?
A. Video is typically variable bit rate.
B. Voice and video traffic are different, but they have the same QoS requirements.
C. Video is typically constant bit rate.
D. Voice and video traffic are the same, so they have the same QoS requirements.
they dont ask about voice, they just throw it in to confuse.. IMHO
What is a characteristic of Video Traffic that governs QOS Requirements… it is Variable…
This question is too generic:
answer A:’Video is typically variable bit rate’ is basically true but imo has nothing in common with QoS.
Looking from pespective of 4-class QoS model: B is correct (voice + video: EF).
Starting from 8-class model: voice (EF) is differentiated from interactive video (EF41).
