Final answer:
NTFS permissions manage file and folder access on NTFS-formatted drives, affecting both local and network-based interactions, while share permissions solely govern network access through shared folders. NTFS permissions offer granular control, whereas share permissions are coarser, with the most restrictive permission being applied in mixed scenarios.
Step-by-step explanation:
The answer to how NTFS permissions differ from share permissions is C) NTFS permissions control access to the file system, while share permissions control network access. NTFS permissions are applied on files and folders stored on NTFS-formatted drives. They control local access to the files and folders, regardless of whether they are accessed locally or over a network. These permissions allow you to set different levels of access such as Read, Write, Modify, and Full Control for individual users or groups.
On the other hand, share permissions apply only when accessing files and folders over a network through a shared folder. Share permissions are less granular and include options such as Read, Change, and Full Control. Since share permissions are set on the shared object itself, they do not affect users who have direct access to the file system locally. In a scenario where both NTFS and share permissions are applied, the more restrictive permission is always the determining factor.
