When you are configuring a wireless access point, which of the following is broadcasted by default
and should be disabled from the security point of view?

A.
Wireless Access Protocol (WAP)

B.
Service Set Identifier (SSID)

C.
MAC address

D.
Multicast address

Explanation:

Service Set Identifier (SSID) is broadcasted by default and should be disabled from the security point
of view.
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. 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.
Answer C is incorrect. Media Access Control (MAC) address is a numerical identifier that is unique
for each network interface card (NIC).
MAC addresses are 48-bit values expressed as twelve hexadecimal digits, usually divided into
hyphen-separated pairs: for example, FF-00-F8-
32-13-19. A MAC address consists of two parts. The first three pairs are collectively known as the
Organizationally Unique Identifier (OUI). The
remaining part is known as device ID. The OUI is administered by IEEE. MAC addresses are also
referred to as hardware addresses, Ethernet
addresses, and universally administered addresses (UAAs).
Answer A 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 D is incorrect. A multicast address is a single address that refers to multiple network
devices. It represents a group of devices
on a segment. Membership of a group is dynamic, i.e., devices can join or leave the group as and
when required. The Mac address format
used by IP for multicasts is 0100.5exx.xxxx, where x is a valid value.
