It's only low signal if you directly score the answer based on presence or correctness of specific details.

Forget about that. The question is an open ended and adaptable tool to get a huge amount of information about knowledge, verbal ability, audience awareness, and all sorts of other directly relevant skills. No trick questions just "teach me everything you know about this subject" and then work with the other party.

That said I suppose there's no reasonable expectation that (for example) most firmware developers necessarily know anything whatsoever about loading a web page. But anyone whose touches network (ie most) should know something.
