Azure Document Intelligence File Requirements
Short answer
C File3.tiff is the only file that meets both the 500 MB size limit and the 50x50 to 10000x10000 pixel dimension requirements.
Question
Key Takeaways
This question tests the minimum and maximum input requirements for Document Intelligence; the common trap is assuming only maximum limits exist and ignoring the minimum 50x50 pixel dimension requirement.
Azure AI Document Intelligence enforces strict file size and dimension limits for document analysis. This page establishes that only files meeting both the 500 MB size limit and the 50x50 to 10000x10000 pixel dimension constraints are valid for analysis.
Common mistake: Selecting D (File2.jpg and File3.tiff) by assuming the 1 KB file size of File2.jpg makes it valid, without checking its 25x25 pixel dimensions against the 50x50 minimum threshold.
Expert Analysis
Why the Answer Is Correct
Option C is correct because File3.tiff (5 MB, 5000x5000 pixels) is the only file that satisfies all input requirements for Azure AI Document Intelligence. The Standard S0 tier permits files up to 500 MB and requires image dimensions to be between 50x50 and 10,000x10,000 pixels. File3 comfortably falls within both the file size and dimension limits.
Why the Other Options Are Wrong
File1.pdf (800 MB) exceeds the 500 MB maximum file size limit for Document Intelligence, eliminating options A and E. File2.jpg (1 KB, 25x25 pixels) fails the dimension requirement because its 25x25 pixel resolution is below the minimum 50x50 pixel threshold, eliminating options B and D. Extremely small dimensions prevent the service from successfully extracting readable text or layout data.
Community Comment Notes
Commenters correctly highlighted the specific dimension limits, noting that "File 2 <50x50 pixels so NO" as Alan_CA observed. Another commenter explicitly validated the boundary, stating "Between 50 x 50 pixels and 10,000 pixels x 10,000 pixels." The Microsoft documentation link provided by chrillelundmark further confirms these exact input requirements for the prebuilt models.

Exam Strategy
Always check both file size and image dimension limits when evaluating Azure AI Document Intelligence inputs. Remember that dimensions have both a maximum (10,000x10,000) and a strict minimum (50x50) threshold that easily disqualifies very small images.

chrillelundmark 👍 5 Answered CHave a look on any of the prebuilt models and you will see File3.tiff is the only one that fits. https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/prebuilt/contract?view=doc-intel-4.0.0#input-requirements

kennynelcon 👍 3 Answered DIn the Standard (S0) tier of Azure AI Document Intelligence, the key constraints you usually run into are: File‐size limits of roughly 200 MB for PDFs and up to 420 MB for images (JPG/PNG/TIFF). Image dimension limits of up to around 10,000 × 10,000 pixels. File1.pdf (800 MB) exceeds the typical 200 MB PDF limit, so it cannot be analyzed. File2.jpg (1 KB, 25×25) is well below both the size and dimension limits for images, so it can be analyzed. File3.tiff (5 MB, 5000×5000) is below the ~420 MB limit and within the 10,000×10,000 pixel limit, so it can be analyzed. Therefore, the files you can analyze in DI1 (S0 tier) are File2.jpg and File3.tiff.

cheetah313 👍 3 Answered BAccording to ChatGPT the max size for PDFs is 200 MB and for images 50 MB. so File 1 is ruled out. But then it also says that the max resolution for image files "should" not exceed 4200 x 4200 pixels. Therefore I would say answer B: "File2.jpg only" is correct.

gyaansastra 👍 1 Answered CThe correct answer is: C. File3.tiffonly Here's why: File1.pdf(800 MB): The Standard S0 pricing tier for Azure AI Document Intelligence has file size limits, and 800 MB exceeds the allowable limit for file analysis. File2.jpg(1 KB, 25 x 25 pixels): This file is too small (both in terms of size and resolution) to be analyzed effectively. The minimum recommended resolution for analysis is typically higher, as such a low resolution might not provide enough data for meaningful results. File3.tiff(5 MB, 5000 x 5000 pixels): This file is within the size and resolution limits for the Standard S0 tier. The system is capable of analyzing high-resolution images like this.

syupwsh 👍 1 Answered CFile3.tiff meets all the requirements for processing by the Azure AI Document Intelligence resource: The file size is 5 MB, which is within the 500 MB limit for the Standard S0 tier. Its dimensions are 5000 x 5000 pixels, which are within the acceptable range of 50 x 50 pixels to 10,000 x 10,000 pixels. C for correct
