H12-841_V1.5 · Question #234
In Huawei's WAN solution, which of the following technologies can optimize the transmission experience of "cross-regional video conferencing" and reduce lag and latency? (Multiple choice)
The correct answer is A. Video traffic priority scheduling (based on DSCP tag priority forwarding of video data packets) B. Edge node caching (caching video streams locally to reduce long-distance transmission latency) C. Dynamic bandwidth adjustment (adjusting video bitrate based on link load). See the full explanation below for the reasoning.

Question
In Huawei's WAN solution, which of the following technologies can optimize the transmission experience of "cross-regional video conferencing" and reduce lag and latency? (Multiple choice)
Options
- AVideo traffic priority scheduling (based on DSCP tag priority forwarding of video data packets)
- BEdge node caching (caching video streams locally to reduce long-distance transmission latency)
- CDynamic bandwidth adjustment (adjusting video bitrate based on link load)
- DNo traffic priority; video and regular data compete for bandwidth.
- EFixed video bitrate, not adjusted according to link status .
