Which authentication methods can be used with WPA and WPA2? (Select Two)

WPA (Wi-Fi Protected Access) and WPA2 are security protocols that protect wireless networks. The correct answer involves authentication methods that support these protocols.

One major authentication method used with both WPA and WPA2 is the Pre-Shared Key (PSK). PSK authentication is a method suitable for personal networks where a single password is shared among users to gain access to the network. This method is often utilized in home networks or small business settings due to its simplicity and ease of deployment.

Another method that can be employed alongside WPA/WPA2 is 802.1X. This is a more secure and robust authentication framework that utilizes a RADIUS server for authenticating users trying to access the network. 802.1X is commonly used in enterprise environments where individual, device-level authorization is critical for security, enabling a higher level of control and security compared to PSK.

In contrast, PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) are not directly associated with WPA/WPA2 authentication methods. These protocols are more often used for authenticating users in different contexts, namely in Point-to-Point Protocol (PPP) networks or when establishing secure connections over networks that do not involve Wi-Fi. Thus, they do
