Selected Answer: B
Since only eight out of twelve cameras are powering on via the PoE switch, the issue is likely related to power limitations, not data. PoE switches have a maximum power budget (measured in watts), and if each camera consumes a certain amount of power, the switch may not be able to support all twelve simultaneously. The engineer should check the switch’s power budget and compare it to the total power requirements of the connected cameras.
