CWS CWS Site Survey Fundamentals 2

Question 1

During a passive wireless site survey, which action best describes what the surveyor does?

Accepted Answer

Listens to existing RF traffic without transmitting probe frames

Answer

A passive survey involves only listening to existing RF transmissions without the survey device transmitting, allowing unobtrusive measurement of existing signal levels.

Question 2

What is the primary purpose of measuring the Signal-to-Noise Ratio (SNR) during a site survey?

Accepted Answer

To determine how well a signal can be distinguished from background RF noise

Answer

SNR quantifies the difference between the desired signal strength and the ambient noise floor, directly predicting data rate and connection reliability.

Question 3

A site surveyor notices the noise floor in a warehouse is -85 dBm. An AP signal reads -75 dBm. What is the SNR?

Accepted Answer

10 dB

Answer

SNR = Signal – Noise = -75 dBm – (-85 dBm) = 10 dB.

Question 4

Which document should a CWS candidate review BEFORE conducting an on-site survey to understand areas that may be off-limits or require escorts?

Accepted Answer

A site security policy or facility access agreement

Answer

A site security policy or facility access agreement identifies restricted zones, required escorts, and safety rules that must be followed during any physical survey.

Question 5

Which type of site survey uses software to model RF propagation before any hardware is installed?

Accepted Answer

Predictive (RF modeling) survey

Answer

A predictive survey uses floor plan data and propagation models in software to estimate coverage without deploying physical hardware.
