During a city WLAN design review, the security architect asks how clients learn which AKM suites and pairwise ciphers an AP supports before associating. Which element advertises those RSN capabilities?
Select an answer to reveal the explanation.
Short Explanation
Beacons and probes are the AP’s sandwich-board on the sidewalk—RSN info tells clients which locks and key ceremonies are on offer before anyone associates. DHCP and RADIUS accounting show up too late to be that advertisement.
Full Explanation
Robust Security Network (RSN) information elements in beacons and probe responses advertise supported AKM suites and pairwise cipher suites so stations can select a compatible security policy. DHCP, RADIUS accounting, and switch SNMP descriptions are not the 802.11 mechanism that advertises WLAN RSN capabilities pre-association. City design reviews should capture the advertised suites as the client-visible security contract for each SSID.
