Secure Wifi - Watchguard Test: Questions With
Correct Solutions
2.4 GHz wavelength Correct Answer - longer wavelengths,
better range
larger channel widths Correct Answer - provide faster speed
and throughput but can create greater interference
5 GHz wavelength Correct Answer - supports faster data rates
at shorter distances, suited for high density deployments because of
greater number of channels that do not overlap
What channel widths do 2.4 GHz support? Correct Answer - 20
and 40 MHz
What channel widths do 5 GHz support? Correct Answer - 20,
40, 80, 160 MHz
omnidirectional antenna Correct Answer - Can transmit and
receive with 360-degree coverage
directional antenna Correct Answer - directs signals where the
antenna oints
Beamforming Correct Answer - technology that enables
wireless devices with omnidirectional antennas to detect location of
other wireless devices and direct a stronger signal in the direction of
the devices
Antenna Gain Correct Answer - The increase in signal strength
by the concentration of radio waves by means of directional
propagation.
, ad hoc network Correct Answer - wireless network where
stations can communicate directly to each other
infrastructure network Correct Answer - wireless clients must
connect through a central wireless point that controls access to the
wireless and wired networks
wireless network service sets Correct Answer - BSS, BSSID,
SSID, ESS
mesh network Correct Answer - one or more AP's connected
to the wired network
best practices for channel planning Correct Answer - - To
avoid co-channel interference, make sure that adjacent APs do not
overlap channels.
- Larger channel widths can provide better throughput, but they can
cause more interference
in high density areas.
How many channels in 2.4 GHz Correct Answer - 14, (1, 6, and
11 do not overlap and these are the most used channels by AP)
How many channels in 5 GHz Correct Answer - 25 that do not
overlap
Which channels are mainly used in 5 GHz Correct Answer - 20
and 40 MHz
For high density deployments Correct Answer - use 20 MHz
channel width in 2.4 GHz to reuse channels
