Community Insight
Document Intelligence limits file uploads to 500 MB and rejects password-protected PDFs, making only non-encrypted, under-limit files valid.
Azure AI Document Intelligence custom extraction models have specific file size and format requirements. This page establishes that only non-locked, properly-sized supported files like JPG and PDF can be used for training.
Choosing options that include XLSX or PNG files over 500 MB, or assuming password-protected PDFs can be processed by the service.

Expert Analysis
Why the Answer Is Correct
Option E is correct because File1 (JPG, 400 MB) and File2 (PDF, 250 MB, not password-locked) both meet the Azure AI Document Intelligence file size limit of 500 MB and the format requirements for training a custom extraction model. Neither file is encrypted, allowing the service to access the raw content for processing and model training.Why the Other Options Are Wrong
Options A, B, C, and D are incorrect because they include files that violate the service limits or security constraints. File3 (PNG, 600 MB) and File4 (XLSX, 600 MB) exceed the 500 MB maximum file size limit for the S0 tier. File5 (PDF, 250 MB, password-locked) is invalid because the service cannot process password-protected or encrypted PDFs to extract text and structures.Community Comment Notes
Commenters correctly point out that the S0 tier supports files up to 500 MB, which immediately disqualifies File3 and File4. As one user noted, "Encryption prevents the service from accessing the necessary data for processing", which eliminates File5. This leaves only File1 and File2 as valid training data.Official Reference
Exam Strategy
Check both the file format and the file size against the 500 MB limit for the S0 tier. Also, always eliminate any files that are password-protected or encrypted, as Document Intelligence requires access to raw content.
