Option A is correct. Document AI documents must be no more than 125 pages long. A 130-page document would exceed this limit, leading to an error such as 'Document has too many pages. Actual: 150. Maximum: 125.'. Option B is incorrect. If the Document AI model does not find an answer in the document, the model does not return a 'value' key. It only retums the 'score' key, which indicates how confident the model is that the document does not contain the answer. Option C is incorrect. Document AI supports processing documents in English, Spanish, French, German, Portuguese, Italian, and Polish, but notes that results for other languages might not be satisfactory. Ukrainian is not listed among the supported languages. Option D is correct. The sources state that in table extraction, if a cell is empty, the Document AI model does not return a 'value' key but does return the 'score' key, which indicates how confident the model is that the cell is empty. This is illustrated in the example output for 'tablel Itak and 'table21date' . Option E is incorrect. For general entity extraction, the Document AI model returns answers that are up to 512 tokens long (about 320 words) per question. The 2048-token limit applies specifically to answers from the model for table extraction.
