Despite the D'Kora showing up many times, its abilities are still pretty vague. In "The Last Outpost", the first time we see the
Ferengi, the D'Kora is mentioned as being slightly below the Galaxy in some respects, and greatly below Federation technology in others.
Later on the capabilities of the D'Kora are not even hinted at, or sometimes made to seem inferior overall.
