Which of the following identifies a wireless network and is sometimes referred to as a “network
name”?

A.
BSSID

B.
SSID

C.
BSS

D.
IBSS

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 and 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
network security. An SSID is sometimes referred to as a “network name.” It allows stations to
connect to the desired network when multiple
independent networks operate in the same physical area.
Answer A is incorrect. BSSID (Basic Service Set Identifier) is an identifier used to identify a particular
BSS (Basic Service Set) within an
area. In Infrastructure BSS networks, the BSSID is the MAC (Medium Access Control) address of the
wireless protected access point (WPA),
whereas in Independent BSS or ad hoc networks, the BSSID is a locally administered MAC address
generated from a 46-bit random number.
The individual/group bit of the address is set to 0, and the universal/local bit of the address is set to
1.
Answer C is incorrect. BSS (Basic Service Set) is the basic building block of an IEEE 802.11 wireless
LAN. BSS is the collection of stations
that can communicate together within an 802.11 WLAN (Wireless Local Area Network). The BSS may
or may not include an AP (Access Point)
which provides a connection onto a fixed distribution system such as an Ethernet network. There are
two types of BSS: Independent Basic
Service Set and Infrastructure Basic Service Set.
Answer D is incorrect. IBSS (Independent Basic Service Set) is an ad-hoc network of client devices
that does not require a central
control access point. In IBSS, the SSID is chosen by the client device that starts the communication.
The broadcasting of the SSID is performed

in a pseudo-random order by all devices that are members of the network.
