Fortinet Exam NSE6_FWF-6.4 Topic 3 Question 20 Discussion
Topic #: 3
Refer to the exhibit.
If the signal is set to -68 dB on the FortiPlanner site survey reading, which statement is correct regarding the coverage area?
A. Areas with the signal strength weaker than -68 dB are shown with black background.
B. Areas with the signal strength equal to -68 dB are zoomed in to provide better visibility.
C. Areas with the signal strength weaker than -68 dB are highlighted in orange and red to indicate that no signal was propagated by the APS.
The FortiPlanner site survey reading is a tool that shows the predicted signal strength of the wireless network based on the floor plan, the placement of the APs, and the propagation model. The signal strength is measured in decibels (dB), which is a logarithmic scale that indicates how much power the signal has. The higher the dB value, the stronger the signal.
The site survey reading allows the user to set a threshold value for the signal strength, which is -68 dB by default. This means that any area with a signal strength equal or stronger than -68 dB is considered to have adequate coverage for most wireless applications. These areas are highlighted in green circles on the floor plan. Any area with a signal strength weaker than -68 dB is considered to have poor coverage or no coverage at all. These areas are shown with different colors, such as yellow, orange, red, or black, depending on how weak the signal is.
Therefore, the correct answer is D. Areas with the signal strength equal or stronger than -68 dB are highlighted in green circles.
