Which of the following is a case sensitive text string used in wireless network and having a maximum
length of 32 characters?
A.
SSID
B.
WTLS
C.
WAP
D.
WEP
Explanation:
SSID stands for Service Set Identifier. It is used to identify a wireless network. SSIDs are case sensitive
text strings and have a maximum
length of 32 characters. All wireless devices on a wireless network must have the same SSID in order
to communicate with each other.
The SSID on computers and the devices in WLAN can be set manually or automatically. Configuring
the same SSID as that of the other
Wireless Access Points (WAPs) of other networks will create a conflict. A network administrator
often uses a public SSID that is set on the
access point. The access point broadcasts SSID to all wireless devices within its range. Some newer
wireless access points have the ability to
disable the automatic SSID broadcast feature in order to improve the network security.
Answer D is incorrect. 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 C is incorrect. The Wireless Access Protocol (WAP) is a technology used with wireless
devices. The functionality of WAP is
equivalent to that of TCP/IP. WAP uses a smaller version of HTML called Wireless Markup Language
(WML) to display Internet sites.
Answer B is incorrect. Wireless Transport Layer Security (WTLS) is a security layer of WAP, which is
specifically designed for a wireless
environment. It provides privacy, data integrity, and authentication for client-server communications
over a wireless network. WTLS ensures
that a client and server are authenticated so that wireless transactions remain secure and the
connection is encrypted. WTLS is required
because a wireless network does not provide end-to-end security.
