Voice and video for emergency operations must keep priority from servers to Wi-Fi clients. What QoS planning is required?
Select an answer to reveal the explanation.
Short Explanation
QoS is a relay race—if the switch drops the baton, fancy WMM on the AP won’t save the call. Map DSCP to WMM end to end and make the wired gear trust those marks. Putting backups in the voice queue just lets the dump truck into the HOV lane.
Full Explanation
Effective WLAN QoS requires consistent classification and trust from application/DSCP through switch queues into WMM access categories. Wireless-only remarks fail when upstream switches remark or ignore DSCP. Placing bulk traffic in voice queues or disabling DiffServ defeats prioritization.
