Question 10

John indicates that he cannot edit the file Test.docx, which is stored on a network shared drive. John
can access and edit other files on the shared drive. You review permissions for the file and see the
permissions shown in the following screenshot.

Which change will allow John to access and edit the Test.docx file, while retaining account-level
control?

  • A. Move the file to a different folder on the same shared drive.
  • B. Modify the NTFS permissions on the file to allow read & execute.
  • C. Modify the share permissions on the file to give John full control.
  • D. Tell John to modify the NTFS permissions on the file to allow read & execute.
Answer:

B


Explanation:
The screenshot shows that John Douglas is explicitly denied "Read & execute" permissions on the file
Test.docx, which overrides any inherited allow permissions. To allow John to edit the file, you must
modify the NTFS permissions on the file and remove or change the Deny rule that applies to his
account. Simply allowing "read & execute" would not be enough; you must grant "Modify" or higher
and remove the Deny.
