What traffic class is voice?

Explanation:
Voice traffic is real-time because it is highly sensitive to delay and jitter, and requires quick, predictable delivery to maintain call quality. In QoS, real-time traffic is typically handled by marking RTP voice packets with DSCP Expedited Forwarding (EF). This marking signals routers to treat voice with very high priority, minimizing queuing delays and ensuring low latency. Other traffic classes like best-effort data, bulk transfers, or scavenger traffic are not designed for this level of priority and would risk degraded voice quality if given the same treatment. So the best fit is real-time traffic marked with DSCP EF for voice.
