Answer: A

Explanation:

Power over Ethernet (PoE) is defined by the IEEE 802.3af and 802.3at standards.

PoE allows an Ethernet switch to provide power to an attached device (for example, a wireless access point, security camera, orIP phone) by applying power to the same wires in a UTP cable that are used to transmit and receive data.
