A user creates a GPO. What do you need to do for that user to manage his or her GPO that he or she created?

Nothing should be done.

Explanation:

Group Policy helps in the provision of a centralized management of operating systems, and applications. It should be noted that a group policy object (GPO) is simply referred to as the configurations involving the group policy.

Nothing should be done to manage the GPO created. When the permission to create a GPO has been given to someone, it means that they can also manage the GPO therefore, nothing needs to be done anymore.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
