C/D? I know blackout means total loss so D looks more accurate, but sometimes people say blackout when parts of the grid go down. Not totally sure which way the exam wants, anyone else pick C?
Maybe C since blackout sometimes gets used when most power is lost but not always 100%, especially in certain regional grid failures. I think it depends how strict the definition is on this exam. Open to counterpoints.
I was thinking C since blackout is often used for outages where demand way exceeds supply, even if some parts are still powered. Could be a trick-exam likes to catch you out with brownout vs blackout terms.
Option C for me. I thought blackout could apply when supply can't keep up and parts go dark, so figured it's not always total grid down. Not super confident though, let me know if anyone disagrees.
D imo. Saw a similar scenario in the official guide and some practice tests, pretty sure brownout is what they mean.
Probably D. Had something like this in a mock and brownout means not enough voltage but still some power, so the grid hasn't totally failed. Blackout would be a full outage. Pretty sure brownout is right here, correct me if I'm off.
Really clear question, appreciate that. I'd pick C, blackout. Blackout usually means a total loss, but sometimes it's used loosely for power shortages. I think it fits if the grid can't meet demand. Not 100% on this though.
