Which PoE mode enables powered-devices detection and guarantees power (CCNA 200-301)
Which PoE mode enables powered-devices detection and guarantees power when the device detected?
A. auto
B. static
C. dynamic
D. active
Solution
Correct answer: B. static.
The static PoE (Power over Ethernet) mode enables powered-devices detection and guarantees power when the device is detected. In this mode, the power sourcing equipment (PSE) provides a fixed amount of power to the powered device (PD) regardless of the PD's power requirements.
The other PoE modes are:
A. auto - The PSE automatically detects the PD's power requirements and adjusts the power accordingly.
C. dynamic - The PSE dynamically adjusts the power based on the PD's changing power requirements.
D. active - The PSE actively monitors the PD's power consumption and adjusts the power accordingly.
