When did Occam's Razor get so dull? The simplest answer is usually the right one.
Umm, you seem to be talking about Trump's Razor here. The simplest answer is never the right one in the real world.
Ol' Occam phrased it a bit differently, but he was still talking out of his ass, assigning mystical qualities to the elegance of simplicity. Every answer is full of assumptions, typically the sum total of assumptions made by mankind up till that point. Being blind to those assumptions doesn't help with giving right answers, but it doesn't necessarily hinder, either. Razors like that are simply irrelevant.
Fandom as far back as the 70s accepted a neutral zone between Federation and Klingon space. A lot of 70s Franz Joseph Fandom made its way into those early movies.
If it's good for the goose... The UFP seems to believe in Neutral Zones. Assuming they have one with the Klingons is fine and well, then. Although not "the simplest" by any definition.
Yes, Romulans used Klingon design. It was a surprise in Enterprise Incident but well known by TWOK.
Funnily enough, it wasn't a surprise even in the TOS episode - Spock knew, he just didn't deem it fit to tell Kirk! No doubt there's a perfectly logical reason for that. But it won't be "simple".
The scenario was crossing the neutral zone to rescue the ship. The trainees knew where in space they were and what border they were crossing. Dialog states Klingon ships. Computer identification, not a mistaken identification from a trainee.
And apparently surprise is supposed to be a factor here. After all, the scenario is about observing how the students deal with the impossible - but if the scenario is based on well-established facts, there's a textbook way for dealing with the scenario, because Starfleet would have written that book in order to cope with these facts out there in the field. Yet we don't see textbook here: different students come up with different solutions, and in the end, none of them matter because the test is not about the solutions.
So the truth value of the scenario is dubious at very best. And probably would be the more counterproductive, the greater.
For dramatic storytelling purposes a line would have been inserted letting the viewers know if said Klingon ships were in Romulan territory. Especially since the first thought uttered would have been "why are Klingons defending Romulan space?"
Defending space? No, they are there to ambush poor Saavik. In the famous words of Admiral Ackbar...
Gamma Hydra was near Romulan space in TOS Deadly Years. I believe the original intent was the KM to be in Romulan territory but the re-use of the TMP footage altered the idea (justified by Harve Bennet stating Klingons were the more common Federation adversary). Occam's Razor implies the simplest answer is Gamma Hydra passed under Klingon control.
Gamma Hydra keeps "changing" all right: in DSC, it's an Andorian colony, in TOS, the target of an expedition led by humans. In the former, it's six lightyears from Klingon-claimed space, in the latter, it's next to the RNZ.
The "simplest" answer would have it be next to everybody. Not particularly difficult in 3D space. But that completely ignores the real issue, which is that it cannot be next to everybody. In TOS, say, there are no Andorians to help out the poor aging expedition leader, or anybody to help out the Andorians. In TWoK, there is no mention of the Romulans or the Andorians. So fuck "simple" - we need a string of offscreen adventures to explain where everybody went.
Or then we can do the only truly simple thing and declare, like Occam would have us do, that "a wizard did it". That is, the simulation is all fake, and has no strings attached.
But where's the fun in that?
