CWNA Wireless Site Survey Fundamentals Quiz

1. What does the term 'near-far problem' refer to in wireless networks?

Clients far from the AP transmit stronger signals than nearby clients

Strong nearby signals overwhelming weak distant signals

The inability to detect distant access points

Frequency separation between 2.4 and 5 GHz bands

Submit

3. Which channel configuration maximizes coverage with minimal interference in a 2.4 GHz network deployment?

Channels 1, 6, 11

Channels 1, 2, 3

Channels 6, 7, 8

All available channels

4. True or False: During a passive site survey, the surveyor actively sends probe requests to locate all available networks.

True

False

Submit

6. Which of the following materials typically causes the greatest RF attenuation?

Drywall

Glass

Metal and concrete

Wood

7. True or False: Co-channel interference occurs when two APs operating on the same channel overlap in coverage area.

True

False

8. What is the relationship between antenna gain and antenna radiation pattern in site survey planning?

Higher gain antennas have narrower coverage patterns

Antenna gain and pattern are independent

Higher gain always produces omnidirectional coverage

Pattern determines the gain value only
