200-301 Question #957: Real Exam Question with Answer & Explanation
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
Question
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?
Options
- AAll four pairs of the cable are used
- BIt detects the device is a powered device
- CThe default level is used for the access point
- DPower policing is enabled at the same time
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.
