See, I would advocate using the filter questions for sorting the apps,
and tell the applicants "We're expecting a 5 words or less answer,
not a history lesson or technical explanation."; if more than 25%
of applicants out of say 1000 get it correct, then the filter is
considered valid, and the ones that pass the most filter questions
are the least likely to not be a waste of time.
I'm not sure which era exactly in which you consider it legal and
kosher to assign to a network, but even if you relax all the rules
that require contiguity, it is still an illegal network mask for end
hosts, just like 255.255.255.254 is; if an applicant doesn't flag it
out as bad/invalid subnet mask in this era, then they might fail the
even if they correctly observe that you can't fit that many hosts in.

Correct... it's not even enough bits for 1 end host; it's enough bits for
1 broadcast address.
