An engineer is designing the physical infrastructure for an IEEE 802.11ac network. Which power design should the engineer use?
The correct answer is C. 802.3af PoE ports. IEEE 802.11ac access points are typically powered via Power over Ethernet. 802.3af (IEEE standard PoE) delivers up to 15.4W per port, which is sufficient for standard 802.11ac APs. The key distinction among the choices is that 802.3af ports (built into the switch) represent the…

Explanation
IEEE 802.11ac access points are typically powered via Power over Ethernet. 802.3af (IEEE standard PoE) delivers up to 15.4W per port, which is sufficient for standard 802.11ac APs. The key distinction among the choices is that 802.3af ports (built into the switch) represent the proper integrated design approach, whereas 802.3af injectors (option D) are mid-span add-on devices-functional but not a clean infrastructure design. 802.3at PoE+ (option A) provides up to 30W and is more than necessary for basic 802.11ac, making it costlier without added benefit. 'Inline PoE' (option B) is a generic/marketing term for mid-span injectors rather than a standards-based design. For a proper IEEE 802.11ac deployment, 802.3af ports integrated into the switching infrastructure are the recommended choice.
