Explanation

Wireless zero configuration supports Wi-Fi Protected Access (WPA), which is the most modern wireless encryption available today. Wi-fi Protected Access (WPA) is an interoperable security standard for Wireless LAN (WLAN). For using WPA, encryption is required. WPA provides encryption by using Temporal Key Integrity Protocol (TKIP). TKIP uses a new encryption algorithm, which is stronger than WEP algorithm. 802.1x authentication is required in WPA. Answer option D is incorrect. WEP (Wired Equivalent Privacy) is supported, but is an earlier/older encryption method. Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security, which is equivalent to wired networks, for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. WEP incorporates a checksum in each frame to provide protection against the attacks that attempt to reveal the key stream. Answer option B is incorrect. There is no WEP2. WEP has been supplanted by WPA (though there is a WPA2). Answer option C is incorrect. PKI is a protocol for exchanging encryption keys but is not an encryption algorithm.
