1. use the dsadd command.-a. incorrect: there is no native cmdlet in windows powershell for creating users.b. incorrect: the setinfo method commits a new user and its properties to active directory, but it must be used in conjunction with commands that create the object and its attributes. it cannot be used as a single command.c. incorrect: a container, such as an ou or domain, provides a create method to create objects of a specified class, but until the setinfo method is used, the object is not saved to active directory. therefore, create is not sufficient as a single command.d. correct: the dsadd command can create a user with a single command.
