Which PoE mode enables powered-devices detection and guarantees power when the device detected?

Answer options

• A. auto
• B. static
• C. dynamic
• D. active

Correct answer: B

Explanation

The correct answer is B (static) because static mode ensures that power is consistently provided to detected devices. The other options, such as auto and dynamic, may not guarantee power delivery in the same way, as they can vary based on detection and negotiation processes.
