I think the interviewee after realizing the shortcomings of the tester's understanding and the author of said "right answers" should have interrupted or ended the probing after a few red flags and politely suggested something along the following lines...

"Look I get the gist of what this screening is trying to do but please write down my answers and feed them to the technical staff who authored this Q&A and have them verify their misunderstandings and have them get back to me please. I am very confident you all have subtle details mixed up and could benefit by a strong candidate who understands such details with a higher level of fidelity."

Guess its another loss given to the recruitment focus on avoiding false positives over false negatives.
