An engineer is determining powering requirements for a P2P wireless link using Cisco Aironet 1572EC access points. Which power method is valid for the access point?
The correct answer is B. Power over Cable. The Cisco Aironet 1572EC is an outdoor, high-power access point that uses Power over Cable (PoC) via a dedicated Cisco power injector. Its power requirements exceed what standard 802.3af (A, 15.4W) and 802.3at/PoE+ (D, 30W) can supply. Cisco Inline Power (C) is a legacy…

Explanation
The Cisco Aironet 1572EC is an outdoor, high-power access point that uses Power over Cable (PoC) via a dedicated Cisco power injector. Its power requirements exceed what standard 802.3af (A, 15.4W) and 802.3at/PoE+ (D, 30W) can supply. Cisco Inline Power (C) is a legacy proprietary pre-standard method. Power over Cable delivers the higher wattage needed for outdoor APs with high-gain antennas through a specialized injector unit, making it the correct and only valid option for this model.
