A POE device requires 47 W of power. What POE specification should be used?
A.
802.3at
B.
802.3af
C.
802.3bt
D.
802. 11at
The Answer Is:
C
This question includes an explanation.
Explanation:
A POE device that requires 47 W of power should use the 802.3bt specification. This is because 802.3bt is the latest POE standard that supports up to 90 W of power delivery over four pairs of wires in an Ethernet cable. The previous POE standards, such as 802.3af and 802.3at, only support up to 15.4 W and 30 W of power delivery over two pairs of wires in an Ethernet cable, respectively. Therefore, they are not sufficient for powering a device that requires 47 W of power. The 802.11at specification does not exist; it is a typo or confusion with the 802.3at specification.
