WGU Introduction to Cryptography (D830) Exam - Topic 1 Question 10 Discussion

802.1X is a port-based network access control framework that enables centralized authentication using an authentication server (commonly RADIUS). EAP (Extensible Authentication Protocol) runs within 802.1X to support many credential types (password-based methods like PEAP, certificate-based methods like EAP-TLS, and others). WPA-Enterprise is the wireless security mode that explicitly uses 802.1X + EAP with an authentication server to perform per-user/per-device authentication and to derive dynamic session keys. By contrast, WPA-PSK uses a pre-shared key without an external authentication server; all users share the same PSK, which is weaker for enterprise identity management. WEP is an older mechanism using static keys and does not provide modern 802.1X/EAP enterprise authentication in the WPA-Enterprise sense. TKIP is an encryption/integrity protocol used under WPA, not the full authentication ''standard'' involving an authentication server. Therefore, the correct choice is WPA-Enterprise.
