Which three EAP protocols are supported in WPA and WPA2? (Choose three)

1. EAP-FAST

2. EAP-AKA

3. EAP-EKE

4. EAP-EEE

The correct answer is: EAP-FAST

WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access II) are security protocols designed to secure wireless networks. They support various Extensible Authentication Protocol (EAP) methods, which enable authentication for clients connecting to the network. EAP-FAST, which stands for EAP Flexible Authentication via Secure Tunneling, is one of the EAP methods supported by both WPA and WPA2. It was developed by Cisco as a replacement for LEAP (Lightweight EAP) and provides a fast and secure way to authenticate users. In the context of WPA and WPA2, EAP-FAST is advantageous because it mitigates the need for a client-side certificate, allowing for quicker authentication processes while maintaining a high level of security through tunnel creation for the subsequent user authentication. EAP-AKA (Authentication and Key Agreement) is another supported EAP method for WPA and WPA2. This protocol is primarily used in mobile networks and offers secure authentication based on a user's SIM card, leveraging a mobile operator's authentication infrastructure. EAP-EKE (EAP with Encrypted Key Exchange) and EAP-EEE (EAP for Enhanced Encryption) are not typically supported in WPA or WPA2. Instead, they exist as specialized E
