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.
WAP
C.
WTLS
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 option 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 option B 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 option C 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.
