What is an advantage of using auto mode versus static mode for power allocation when an access point is connected to a PoE switch port?
The correct answer is B. It detects the device is a powered device. Auto mode allows the PoE switch to automatically detect whether a powered device (such as an access point) is connected and then dynamically allocates power based on the device's actual requirements. This detection ensures that power is only supplied when a compatible powered dev

Explanation
Auto mode allows the PoE switch to automatically detect whether a powered device (such as an access point) is connected and then dynamically allocates power based on the device's actual requirements. This detection ensures that power is only supplied when a compatible powered device is present, improving efficiency and preventing unnecessary power usage. In contrast, static mode pre-allocates a fixed amount of power to the port regardless of whether a powered device is connected or not, guaranteeing power but without detection-based negotiation. Therefore, the key advantage of auto mode is the detection of the powered device and dynamic power allocation based on that detection.
