What is a feature of WPA?

TKIP/MIC encryption. WPA was introduced as an interim improvement over WEP and is strongly associated with TKIP and MIC. TKIP replaced WEP’s weak key handling, and MIC added message integrity protection to detect tampering. 802.1X can be used with enterprise WLAN authentication, but it is not the most distinctive feature of WPA in this option set. Preshared keys are also supported, but the defining protocol improvement over WEP is TKIP/MIC. Cisco CCNA 200-301 v1.1 Network Access expects engineers to place WEP, WPA, WPA2, and WPA3 in the right security progression. The corrected answer is TKIP/MIC encryption. WPA2 moved the preferred encryption mechanism to AES/CCMP, while WPA3 added SAE for stronger personal authentication. Selecting 802.1X here misses the feature that specifically identifies WPA.
