I am studying for the Part 107 exam and am puzzled by the instructions re monitoring nearby air traffic with a handheld radio while flying a drone. Given DJI's Geozones and LAANC's demarcation of allowable places to fly, I do not know of scenarios in which I would need to monitor air traffic. Perhaps if I were surrounded by airports, as seems to be the case in heavily populated parts of the US, monitoring air traffic would be helpful, but not where I live. I would appreciate hearing from anyone who monitors air traffic on a radio and an explanation of why.
