Your customer is using Windows XP Service pack 1 with wireless zero configuration. Which is the
most modern encryption supported with
wireless zero configuration?

A.
WPA

B.
WEP2

C.
PKI

D.
WEP

Explanation:

Wireless zero configuration supports Wi-Fi Protected Access (WPA), which is the most modern
wireless encryption available today.
What is WPA? Hide
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.
What is WEP? Hide
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.
