Supported File Formats for Microsoft Security Copilot Uploads
Short answer
E File1.docx, File2.pdf, and File3.txt are all supported formats for uploading to Microsoft Security Copilot to inform responses, assuming they meet the size constraints.
Question
You have the files shown in the following table.

Each file contains a copy of your company's compliance policy.
You need to ensure that Security Copilot responses are informed by the compliance policy.
Which files can be uploaded to Security Copilot?
Key Takeaways
The main trap is excluding valid formats like DOCX or PDF; Security Copilot supports multiple common text-based document types including DOCX, PDF, TXT, and MD.
This SC-200 question tests knowledge of file type compatibility when uploading documents to Microsoft Security Copilot. The correct answer identifies that DOCX, PDF, and TXT files are all supported for providing context.
Common mistake: Option D is a plausible distractor if one mistakenly believes DOCX is not supported or if there's an assumption about file sizes not shown. However, since DOCX is explicitly listed as a supported format in official docs, excluding it is incorrect.
Expert Analysis
The question asks which files can be uploaded to Microsoft Security Copilot to inform its responses with a compliance policy. The key constraint is the file format support for uploading documents to Security Copilot.
According to Microsoft's official documentation for Security Copilot, users can upload files to provide context for queries. Supported file types include common text formats such as DOCX, PDF, TXT, and MD. There are also size constraints: individual files must not exceed 3 MB, and the total upload size is limited to 20 MB. However, the question does not provide file sizes in the table (the image exhibit is referenced but not visible here), so we must assume the files meet the size requirements unless stated otherwise. The primary filter is the file extension/type.
Let's analyze the options based on supported formats:
- File1.docx: DOCX is a supported format.
- File2.pdf: PDF is a supported format.
- File3.txt: TXT is a supported format.
Since all three file types (.docx,.pdf,.txt) are explicitly supported by Microsoft Security Copilot for uploading content to inform responses, all three files should be eligible for upload, assuming they meet the size limits. Therefore, the correct answer should include all three files.
Looking at the options: A. File1.docx only - Incorrect, excludes others. B. File3.txt only - Incorrect, excludes others. C. File1.docx and File3.txt only - Incorrect, excludes PDF. D. File2.pdf and File3.txt only - Incorrect, excludes DOCX. E. File1.docx, File2.pdf, and File3.txt - Correct, includes all supported types.
The suggested answer D is likely incorrect because it arbitrarily excludes DOCX, which is a standard and supported format. The comments mention checking for common text file types like DOCX, MD, PDF, or TXT, confirming that DOCX is valid. Thus, if all files are within size limits, all three can be uploaded.
