Ann is a member of the Sales group. She needs to collaborate with Joe, a member of the IT
group, to edit a file. Currently, the file has the following permissions:
Ann:read/write
Sales Group:read
IT Group:no access

If a discretionary access control list is in place for the files owned by Ann, which of the following
would be the BEST way to share the file with Joe?

A.
Add Joe to the Sales group.

B.
Have the system administrator give Joe full access to the file.

C.
Give Joe the appropriate access to the file directly.

D.
Remove Joe from the IT group and add him to the Sales group.

Explanation:
Joe needs access to only one file. He also needs to ‘edit’ that file. Editing a file requires Read and
Write access to the file. The best way to provide Joe with the minimum required permissions to
edit the file would be to give Joe the appropriate access to the file directly.
