She told me that the way she got her perfect score was by realizing when the questions were wrong and thinking of what answer the test creators believed to be correct.
She had to outguess the test creators and answer the questions wrong -- in the "right" way.
This seems like a similar situation.
"I probably won't ever do it like that and/or there's a syntax error in all four of the answers... but this is the answer you want to hear. It's wrong, mind you, but it's what you want to hear."
They're getting better at it though. More recently I've done their devops certification and it looks like they're recommending somewhat more sane practices now...
There were still questions where even after three or four tries at certification / reading up on whatever Microsoft thinks is 'good' we didn't find 'the correct answer' according to Microsoft though... ¯\_(ツ)_/¯
I tried the dispute process but it's basically impossible to dispute / report broken questions unless you have a photographic memory.
The question was "How do you delete all files in the current directory?". Using DOS 6.22 (I think, it's from memory).
My answer "del." was marked incorrect. Because the teacher didn't know enough about DOS to understand that's the standard shortcut for "del .". And the teacher refused to even try out the command, lets alone fix the incorrect mark. sigh
In my TAFE class, I was asked to list two examples of operating systems.
I listed Linux and eComStation. The teacher had never heard of eComStation and marked me wrong.
Refused to correct my mark even when I proved him right. I'm still bitter about it a decade later.
