    A network administrator is planning a PoE deployment for a new office. The switch has a PoE budget of 740W. The administrator needs to power 20 IP phones (15.4W each), 10 cameras (30W each), and 5 access points (60W each). The total demand is 308W + 300W + 300W = 908W, which exceeds the budget. The administrator wants to ensure that the cameras and access points are always powered, but the phones can be powered if budget allows. What is the best strategy?
