$3\mathrm{.}4\mathrm{.}10$ Lesson Review

Question $15$ of $16$

$$

What is the significance of the "four$-$pair" mode in Power Over Ethernet $($PoE$)$ technology?

It delivers power only, without data transmission.

It delivers power over all four pairs of wires in the cable.

It is only compatible with the original PoE standard.

It is used exclusively for $10$ G Ethernet connections.

I want to review this question later. $($Optional$)$
