Which protocol is used with WPA to provide enterprise authentication?

• A. Wireless Transportation Layer Security
• B. Extensible Authentication Protocol
• C. WTLS
• D. SSL

Answer: (B)

WPA in enterprise deployments relies on a centralized authentication flow, typically using 802.1X. Extensible Authentication Protocol is the mechanism that carries the credentials between the client, the wireless access point, and the authentication server (often a RADIUS server). Because EAP is a flexible framework that can encapsulate multiple methods—such as EAP-TLS or PEAP—it's the standard way to achieve strong, scalable enterprise authentication over Wi-Fi. The other options aren’t used for this purpose: WTLS and similar protocols came from WAP-era security, and SSL is for securing web traffic, not for handling wireless network authentication.
