Secure Wifi - Watchguard Test Exam
UPDATED QUESTIONS AND CORRECT
ANSWERS
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
