CWDP: Certified Wireless Design Professional v303 — Question 26

When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?

Answer options

• A. Missing AP licenses in the controller
• B. Spanning-tree convergence
• C. Layer 3 routing
• D. Lack of PoE budget on the switch

Correct answer: D

Explanation

The correct answer is D, as a lack of PoE budget on the switch would prevent the AP from receiving the necessary power, even if the cable is functional. Options A, B, and C are irrelevant in this situation, as they do not directly affect the power delivery to the AP.
