A customer wants to provide wireless coverage in a parking lot outside of a building.

This question hinges on a fundamental network engineering constraint: the maximum transmission distance of copper Ethernet cabling. IEEE 802.3 standards specify a maximum segment length of 100 meters (328 feet) for all standard PoE and Ethernet over Category 5e, 6, or 6A UTP copper cabling. The parking lot light poles are approximately 200 meters from the closest wiring closet — more than double the maximum copper distance. This immediately eliminates Options A and D, which specify Category 6 UTP cabling: at 200 meters, UTP copper cannot reliably carry Ethernet at any supported speed, and PoE cannot be delivered over this distance regardless of standard. The correct solution is fiber optic connectivity between the wiring closet and the parking lot, combined with a local AC/DC power module at each pole location. Fiber optic cabling supports single-mode runs of kilometers and multi-mode runs of hundreds of meters at Gigabit speeds — easily spanning 200 meters. At the AP mounting location on the light pole, an AC/DC power module (powered from the pole ' s existing electrical supply) converts AC power to the DC power the AP requires. Option B (fiber with 802.3af) is incorrect because PoE cannot be delivered over fiber — 802.3af requires copper cabling for simultaneous power and data delivery.
