Exam Questions and CORRECT Answers
Wireless Personal Area Network or WPAN - CORRECT ANSWER - This type of network
allows users to connect various devices wirelessly to their own personal area network, including
computer keyboards, mice, and headsets.
Frequency Hopping Spread Spectrum or FHSS - CORRECT ANSWER - What technology
does Bluetooth use for wireless communication?
IEEE 802.15 - CORRECT ANSWER - What wireless standard does Bluetooth fall under?
The unlicensed 2.4 GHz Industrial, Scientific and Medical or ISM band. - CORRECT
ANSWER - What band does Bluetooth operate in?
False: Although infrared technology was a part of the original 802.11 standard, it is considered
obsolete. - CORRECT ANSWER - True or False: Infrared technology is part of the 802.11
standard and is commonly used for wireless communication today.
Wireless Local Area Network or WLAN - CORRECT ANSWER - A group of computers,
contained in the same physical area and usually are bounded by the perimeter of a building or a
group of buildings, that are connected wirelessly in a specific arrangement called a topology.
The unlicensed 2.4 GHz ISM band and the unlicensed 5 GHz Unlicensed National Information
Infrastructure or UNII band. - CORRECT ANSWER - What are the most common
frequency spectra for WLANs to operate in?
Wireless Metropolitan Area Network or WMAN - CORRECT ANSWER - Networks that
may span from several blocks of
, buildings to entire cities and interconnect devices for access to computer resources incorporating
wireless technology in an area larger than that covered by LANs but smaller than the areas
covered by WANs.
IEEE 802.16 standard - CORRECT ANSWER - The standard developed for a Wireless
Metropolitan Area Network or WMAN and may include the Worldwide Interoperability for
Microwave Access or WiMAX category.
Wireless Wide Area Network or WWAN - CORRECT ANSWER - A network
encompassing a very large geographical areas and may include different wireless technologies,
including cellular. It also provides wireless broadband communications for Internet access
through the use of special external adapters or even adapters built into notebook computers or
other mobile devices.
100 meters - CORRECT ANSWER - What is the physical distance limit that the IEEE
802.3 Ethernet standard allows for a copper-wired connection?
wireless hotspot - CORRECT ANSWER - A location that offers wireless network
connectivity for free or for-profit public or patron services. It allows a variety of mobile devices,
computers,
tablets, smart phones, and so on to connect to and access public Internet and private network
resources.
captive portal - CORRECT ANSWER - When a user connects to a hotspot router, they will
be prompted with a web page for authentication. At this point they might be asked to enter
information such as an account number, username and password, or a credit card number to
allow usage for a limited period of time. In the case of a free hotspot, typically this web page
lists terms and conditions the user agrees to prior to accessing the Internet.
False: Wireless hotspots are not secure and require users to use a Virtual Private Network or
VPN to create a secure tunnel. - CORRECT ANSWER - True or False: Wireless hotspots
offer a secure wireless connection to the internet.
