A network administrator at a small office wants to simplify the configuration of mobile clients connecting to an encrypted wireless network.
Which of the following should be implemented in the administrator does not want to provide the wireless password or he certificate to the employees?

A. B. C. D.A.
Option A: WPS (Wi-Fi Protected Setup) is a network security standard designed to simplify the process of connecting wireless devices to a secure wireless network. However, WPS has known vulnerabilities and should not be used as the sole method for securing a wireless network.
Option B: 802.1x is a network access control protocol that provides authentication, authorization, and accounting (AAA) services for devices trying to connect to a network. 802.1x is a robust security mechanism, but it requires a certificate-based infrastructure and can be complex to implement.
Option C: WPA2-PSK (Wi-Fi Protected Access II with Pre-Shared Key) is a security protocol that uses a shared key to authenticate devices and encrypt data on a wireless network. While WPA2-PSK is easier to configure than 802.1x, it requires the pre-shared key to be distributed to all authorized users, which can be a security risk if the key is compromised.
Option D: TKIP (Temporal Key Integrity Protocol) is a security protocol used in conjunction with WPA and WPA2 to provide data encryption and key management on wireless networks. However, TKIP is vulnerable to certain attacks, and it is recommended to use AES (Advanced Encryption Standard) instead.
Therefore, based on the above analysis, the best option for the network administrator to simplify the configuration of mobile clients connecting to an encrypted wireless network while not providing the wireless password or certificate to the employees would be Option B: 802.1x. While it may require more infrastructure and configuration, it provides a more robust and secure solution than the other options.
