A document file that is stored on a file server is directly edited on a PC and then an attempt is made to overwrite the file, but the message “You do not have permission, so the file cannot be saved” is displayed. Which of the following is the appropriate combination of permissions that were set for the document file and the folder that it is stored in?
Explanation
File read Yes, file write No, folder read Yes — the file could be found and opened, and only saving over it failed.
Check each step against the permission it needs:
- •Finding the file in its folder on the server needs read permission on the folder: it succeeded, so Yes.
- •Opening and editing the document on the PC needs read permission on the file: it succeeded, so Yes.
- •Overwriting the file failed with "You do not have permission": write permission on the file is No.
Answer (b)
Why not others:
- •(a) — file write is Yes, so the overwrite would have succeeded; without folder read the file could not even have been reached
- •(c) — without file read the document could not have been opened for editing, and with file write the save would have succeeded
- •(d) — without file read the document could not have been opened and edited in the first place
Key rule: Read each permission against one action: folder read to reach the file, file read to open it, file write to save changes over it; the step that fails names the missing permission.
