In the fifth season of Voyager, we get to see that Species 8472 built a Terrasphere specifically to train for the invasion of the Federation. According to not-Boothby, the facility was built last year (2374). It recreated Starfleet Command circa 2371 to 2373. Given that Scorpion I/II starts in last days of 2373 and the first days of 2374 and that it takes place right after Star Trek: First Contact given their Stardates.
From what not-Boothby said, their only Federation contact was Voyager but assumed there were other Starfleet vessels in the Delta Quadrant. Given that Voyager's Starfleet information was from 2371, so the simulation was only Starfleet Command 2371 and that the information about the ships stated, Intrepid and Hor'cha, were also from that time period. The reason why I am making this statement, is because Memory Alpha doesn't state that the Intrepid of 2371 was on a three-year RNZ patrol and the Hor'cha received a Starfleet exchange officer in that year.
