Wi-Fi联盟制定的安全认证方案WPA（Wi-Fi Protected Access）是 （ ） 标准的子集。
A.IEEE 802.11
B.IEEE 802.11a
C.IEEE 802.11b
D.IEEE 802.11i
B.IEEE 802.11a
C.IEEE 802.11b
D.IEEE 802.11i
参考答案
参考解析
解析：IEEE 802.11i是IEEE 802.11协议标准的扩展，于2004年正式被IEEE通过，取代原来脆弱的WEP加密技术。IEEE 802.11i为使用IEEE 802.11a、IEEE 802.11b和IEEE 802.11g标准的网络提供加密技术和安全认证功能，这样的网络被描述为RSN（Robust Security Network，健壮安全的网络）。
