The answer is correct: First = File001 Last = File000 At least 50 positive samples (up to 500) and at least 150 negative samples (up to 1500) are required to train a classifier. The more samples you provide, the more accurate the predictions the classifier makes will be. The trainable classifier processes up to the 2000 most recently created samples (by file created date/time stamp).

Agreed. The 2000 samples are a mix of positive and negative samples

The question is poorly formulated. If it is positive content it is up to 500 files, if it is negative content you can upload up to 1500. The type of content is not specified. https://learn.microsoft.com/es-es/purview/trainable-classifiers-get-started-with

I think the answer is as follows. First = File001 Last = File500 Creating a trainable classifier requires between 50 and 500 seed sample files. If there are more than 500 files uploaded to a Microsoft SharePoint Online site, only the first 500 files are processed based on the time stamp.

no, you are wrong. 500 files only for positive content. But the question and don't split into positive and negative content. 500 files for positive content and 1500 for negative content results into 2000

Negative seed content has to be contained in a separate SharePoint folder, so this is clearly only the positive seed content. So I agree with Dools: First = File001 Last = File500
