City hall laptops show notes about preauthentication and PMKSA caching on capable Wi-Fi clients. What do those advanced client features primarily help with?
Select an answer to reveal the explanation.
Short Explanation
Think of preauth and PMKSA caching like keeping your building badge warm in your pocket so the next door opens faster. They help capable clients re-authenticate quicker when roaming—not skip security setup. You still need the right SSID and security settings.
Full Explanation
Preauthentication and PMKSA caching are advanced client features that reduce roam-time authentication delay on Enterprise (and related) networks when both client and WLAN support them. They do not substitute for correct SSID or security configuration, change band preference by themselves, or replace QoS settings. At CWTS technician depth, recognize them as roam-acceleration capabilities rather than a redesign of the WLAN architecture.
