Dispatch voice handsets roam across city-yard APs and drop syllables during full 802.1X each hop. Which secure roaming feature should the design select first?
Select an answer to reveal the explanation.
Short Explanation
Full 802.1X on every AP hop is like re-badging at every doorway while talking on the radio—calls stutter. 802.11r FT keeps security but speeds the handoff for voice. Open SSIDs and WEP are the wrong shortcuts.
Full Explanation
802.11r Fast BSS Transition is designed to accelerate secure roaming while preserving enterprise security context, which benefits latency-sensitive voice over WLAN. It reduces the need to repeat a full 802.1X exchange on every BSS transition when properly supported. Deprecated crypto or portal re-auth harms both security and call quality.
