The 15 questions situated at the end of the section, on question number 4 asks
"The PoE standard 802.3af has 15.4 watts of DC power, while the PoE standard 802.3bt has 51 watts on type 3 and 71.3 watts on type 4. For smaller deployments, you could use the PoE standard________that only uses 25.5 watts. My answer is PoE standard 802.3at as illustrated in the teaching video.
What can I do to bypass this issue?
Might be miss wording so try another class in standard, would not be the first time.
