False - ANS-Pont Coordination Function (PCF) is the currently implemented collision avoidance
system
True or False
Wi-fi - ANS-The wireless networking market these days is dominated by the most common
implementation of the IEEE 802.11 wireless standard
dipole - ANS-The standard straight wire antennas provide the most omnidirectional function are
called _________ antennas
True - ANS-Whitelisting and blacklisting are labor-intensive processes with whitelisting requiring
far more work
True or False
heat - ANS-a ______ map is nothing more than a graphical representation of the RF sources on
your site, using different colors to represent the intensity of the signal
Distributed Coordination Function (DCF) - ANS-______ is the current 802.11 collision avoidance
method that specifies rules for sending data onto the network media
Infastructure - ANS-__________ mode uses a WAP that, acts as a hub for all wireless clients
site survey - ANS-Before installing a Wifi network, be sure to do a ___________ to locate any
obstacles that need to be overcome and to determine the best location for your access points
Power over Ethernet - ANS-Which technology enables WAPs to receive their power from the
same Ethernet cables that transfer their data
signal-to-noise ration (SNR) - ANS-We measure RFI with the ______ essentailly comparing the
signal strength and the overall interference in the space
roaming - ANS-As clients move through the space covered by the broadcast area, they will
change WAP connections seamlessly, a process called
Rogue access point - ANS-a ________ is simply an unauthorized access point
True - ANS-the 802.11 standard defines both how wireless devices communicate and how to
secure that communication
True or False
, Radio Frequency (RF) waves
Enables flexibility and mobility - ANS-What does WiFi use to communicate between devices and
why?
IEEE 802.11 wireless Ethernet standard - ANS-What standard is implemented for wifi?
since the late 1990s - ANS-Since when have Wifi technologies been around
interconnects wireless network nodes with wired networks - ANS-What does Wireless Access
Points do?
A hub at layer 1 - ANS-What does a basic WAP operate like
link state - ANS-What term represents the condition of whether a wireless device is connected?
Wireless network mode
peer-to-peer
mesh topology
Works well for small groups of computers for temporary networks
IBSS - ANS-Ad hoc mode
Independent Basic Service Set (IBBS) - ANS-How are wireless devices organized?
Two or more wireless nodes communicating in ad hoc form - ANS-Independent Basic Service
Set
More common
Uses one or more WAPs
wired star topology
BSS and ESS - ANS-Infrastructure mode
Serviced by a single WAP - ANS-Basic Service Set (BSS)
Serviced by two or more WAPs - ANS-Extended Service Set (ESS)
Wireless networking Range - ANS-What is greatly affected by environmental factors and hard to
define
maximum range - ANS-Actual range is about half of manufacturers listed __________________
