CWDP: Certified Wireless Design Professional v303 — Question 9

What is the minimum PoE budget needed on a switch to support 6 (six) APs that can only be powered using IEEE 802.3at if no other details are provided?

Answer options

• A. 320 W
• B. 60 W
• C. 180 W
• D. 240 W

Correct answer: B

Explanation

The correct answer is B, 60 W, because each IEEE 802.3at compliant access point can consume up to 30 W, so for 6 APs, the total power requirement is 180 W. However, to calculate the minimum budget, it is essential to consider the power supplied by the switch rather than the total requirement. The other options are incorrect as they exceed the minimum necessary budget.
