CWNA: Certified Wireless Network Administrator v108 — Question 12

A dual-band 802.11ac AP must be powered by 802.3at PoE. As a class 4 device, what minimum power level should be received at the AP?

Answer options

• A. 30 W
• B. 12.95 W
• C. 25.5 W
• D. 15.4 W

Correct answer: C

Explanation

The correct answer is C, 25.5 W, because class 4 devices under 802.3at PoE receive a minimum of 25.5 W. The other options, A (30 W), B (12.95 W), and D (15.4 W), do not meet the requirements for class 4 devices, making them incorrect choices.
