CCNA: Cisco Certified Network Associate — Question 757

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?

Answer options

• A. Power policing is enabled at the same time.
• B. The default level is used for the access point.
• C. All four pairs of the cable are used.
• D. It detects the device is a powered device.

Correct answer: D

Explanation

The correct answer is D because auto mode allows the PoE switch to identify the connected device as a powered device, ensuring it receives the appropriate power. The other options do not accurately describe advantages of auto mode; for instance, A and B do not pertain to the detection capability, while C relates to power usage rather than allocation mode advantages.
