Question 1: What is the 2.4 GHz wavelength
characteristic?
CORRECT ANSWER : longer wavelengths, better range
Question 2: What do larger channel widths provide?
CORRECT ANSWER : provide faster speed and
throughput but can create greater interference
Question 3: What is the 5 GHz wavelength characteristic?
CORRECT ANSWER : supports faster data rates at
shorter distances, suited for high density deployments because of greater number of channels that do not overlap
Question 4: What channel widths do 2.4 GHz support?
CORRECT ANSWER : 20 and 40 MHz

Question 5: What channel widths do 5 GHz support?
CORRECT ANSWER : 20, 40, 80, 160 MHz
Question 6: What is an omnidirectional antenna?
CORRECT ANSWER : Can transmit and receive with
360-degree coverage
Question 7: What is a directional antenna?
CORRECT ANSWER : directs signals where the
antenna points
Question 8: What is 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
Question 9: What is Antenna Gain?
- | Page
CORRECT ANSWER : The increase in signal strength
by the concentration of radio waves by means of directional propagation.
Question 10: What is an ad hoc network?
CORRECT ANSWER : wireless network where stations
can communicate directly to each other
Question 11: What is an infrastructure network?
CORRECT ANSWER : wireless clients must connect
through a central wireless point that controls access to the wireless and wired networks
Question 12: What are wireless network service sets?
CORRECT ANSWER : BSS, BSSID, SSID, ESS
Question 13: What is a mesh network?
CORRECT ANSWER : one or more AP's connected to
the wired network

Question 14: What are the 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.
Question 15: 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)
