An administrator wants to restrict access to a particular database based upon a stringent set of requirements. The organization is using a discretionary access control model. The database cannot be written to during a specified period when transactions are being reconciled. What type of restriction might the administrator impose on access to the database

Time of the day and object restrictions

Explanation:

From the question, we understand that the database is not allowed to be accessed at a certain period of time.  

Because this has to do with time (period), the administrator will need to set a time of the day object restriction on the database in order to prevent the users from accessing the database objects
