In the Administering Windows Server Hybrid Core Infrastructure content for File Services, Microsoft describes File Server Resource Manager (FSRM) as the feature used to control the types of files that users can store on file servers. The guide explains that a file screen "prevents users from saving unauthorized file types on a volume or in a folder by applying a file group (such as Audio and Video) or custom file name patterns (for example, *.mp4)." It further clarifies that file screening "does not affect access permissions to other files and folders and allows permitted file types to be stored without restriction." By contrast, NTFS permissions govern access (read/write/modify) and "cannot filter by file extension," and NTFS quotas and File Management Tasks address capacity and automated tasks, not content blocking. Therefore, to stop users from storing .MP4 while allowing all other files, you create a File Screen on the path to Share1 and block either the built-in Audio and Video file group or a custom pattern *.mp4. This aligns precisely with the exam guide's directive that FSRM File Screening is the supported and intended method to restrict file types on Windows file shares while leaving other file operations unaffected.
