Which of the following WLAN security policies support open link authentication?

Comprehensive Explanation: WEP (Wired Equivalent Privacy) is the only security policy in this list that supports open link authentication, which means no actual user credentials are required to associate with the network. WEP uses a shared key for encryption but offers minimal protection and is considered insecure. Other security methods like WPA, WPA2-PSK, and WPA2-802.1X use more secure forms of authentication, requiring credentials such as a password or centralized authentication server.
