Answer 1

Explanation:

With groups, the task is much simpler: create a student group and a staff group, placing each user in the proper group. The entire group can be granted access to the appropriate directory. To add or remove an account, one must only need to do it in one place (in the definition of the group), rather than on every directory. This workflow provides clear separation of concerns: to change access policies, alter the directory permissions; to change the individuals which fall under the policy, alter the group definitions.
