Question 2

During a validation survey, a technician measures a consistent RSSI of -67 dBm in a conference room. The noise floor in the same area is measured at -92 dBm. What is the Signal-to-Noise Ratio (SNR) for this location?

Accepted Answer

25 dB

Answer

159 dB

Answer

-25 dB

Answer

Question 3

A technician performing a site survey in an office breakroom notices significant, wideband RF interference across the entire 2.4 GHz band every day around lunchtime. This interference is not present on the 5 GHz band. Which of the following is the MOST likely source of this non-Wi-Fi interference?

Accepted Answer

Microwave oven

Answer

Bluetooth headsets

Answer

Adjacent channel interference from another AP

Answer

Co-channel interference from a neighboring network

Question 4

A network engineer needs to troubleshoot a Wi-Fi performance issue in a manufacturing facility. It is suspected that machinery is emitting RF energy that disrupts the wireless network. What is the best tool to visualize ALL RF activity, including Wi-Fi and non-Wi-Fi sources, across the frequency spectrum?

Accepted Answer

A spectrum analyzer

Answer

A protocol analyzer

Answer

A throughput tester

Answer

A standard Wi-Fi scanner

Question 5

Before starting a physical walk-through with site survey software, what is the most critical first step to ensure the accuracy of the collected data points on the floor plan?

Accepted Answer

Calibrate the map by defining the distance between two known points.

Answer

Identify all potential sources of interference.

Answer

Perform a throughput test to the default gateway.

Answer

Configure the survey access point with the final production SSID.

Question 6

A post-deployment survey in a high-density office reveals an area where two APs, both configured on channel 36 in the 5 GHz band, provide coverage with a strong RSSI of -60 dBm each. Users in this overlap area report poor performance and frequent connection issues. This issue is an example of what?

Accepted Answer

Co-Channel Interference (CCI)

Answer

Adjacent Channel Interference (ACI)

Answer

The hidden node problem

Answer

Excessive RF attenuation
