A file on a Linux server has default permissions of rw-rw-r–. The system administrator has verified
that Ann, a user, is not a member of the group owner of the file. Which of the following should be
modified to assure that Ann has read access to the file?

A.
User ownership information for the file in question

B.
Directory permissions on the parent directory of the file in question

C.
Group memberships for the group owner of the file in question

D.
The file system access control list (FACL) for the file in question

Explanation:
The file permissions according to the file system access control list (FACL) are rw-rw-r–.
The first ‘rw-‘ are the file owner permissions (read and write).
The second ‘rw-‘ are the group permissions (read and write) for the group that has been assigned
the file.
The third ‘r–‘ is the All Users permissions; in this case read only.
To enable Ann to access the file, we should add Ann to the group that has been assigned to the
file.
