A company commissioned a site survey to check wireless network coverage. The technician noticed undesirable levels of RSSI in different areas of the office. Which of the following levels did the technician most likely notice?

In wireless networking, RSSI (Received Signal Strength Indicator) values are typically expressed in negative dBm (decibel milliwatts). The strength of the signal is inversely related to the dBm value: the closer to zero the value is, the stronger the signal. Conversely, the further from zero (i.e., more negative), the weaker the signal. At -82dBm, the signal is significantly weak, which is likely what the technician noticed as undesirable coverage during the site survey.
I passed today. I studied 1-852 until I felt good about it. Most of the questions I had were towards the end of this dump. Only two of the pbq questions I had were on here. I wouldn't haven't of passed without studying this whole thing though. Thanks to everyone and ExamTopics for the help. Good luck to all. STUDY THOSE PBQS AND YOU CAN FIND THEM!
IF YOU CAN FIND THEM*
All RSSI values will be negative, but the closer to 0, the stronger. In this case, -82dBm is going to be very weak, and what the tech is looking for
