Answer:
D. The technician should be setting NTFS permissions instead of using Group Policy.
Step-by-step explanation:
If the technician wants to limit the access of the sales department to files of the accounting department, then the best way to do so is through the use of NTFS permissions. NTFS permissions affect both local users and network users. Moreover, with this method, a person can choose to share entire drives or individual folders with the network. The technician would be able to do this if he is the administrator. He would also be able to provide access control.
