Final answer:
To give users the functionality to backup and restore files without allowing them to make changes to the system, the technician should implement user access controls and configure user accounts as standard users rather than administrators. Additionally, providing backup and restore software that requires administrator credentials to run can further restrict access to system settings.
Step-by-step explanation:
The technician can give users the functionality to backup and restore files on their computers without allowing them to make changes to the system by implementing user access controls. User access controls are settings that determine what actions users can perform on a system. The technician can set the user access controls to allow users to backup and restore files, but restrict their ability to make changes to the system settings.
By configuring the user accounts as standard users instead of administrators, the technician can prevent users from installing software or modifying system settings. This ensures that users have the ability to backup and restore files, but they do not have the privileges to make changes to the system.
Additionally, the technician can provide users with backup and restore software that requires administrator credentials to run. This way, users can initiate the backup and restore process, but they cannot access or modify the software settings without the appropriate permissions.
