Final answer:
The dsadd command is employed via the command prompt to establish a new user account within Active Directory. The correct answer is D. dsadd.
Step-by-step explanation:
In an Active Directory Domain Services (AD DS) domain, the command prompt utility for creating a new user account is 'dsadd.'
This versatile command, designed for Active Directory object creation, includes the capability to establish user accounts.
The syntax for creating a user account with 'dsadd' is structured as follows: dsadd user "DN" [-samid ] [-upn ] [-fn ] [-ln ] [-display ] [-desc ] [-memberof ...].
Here, "DN" represents the distinguished name of the container where the user account is to be generated, and the additional parameters allow specification of various user account details.
Leveraging 'dsadd' in the command prompt facilitates the streamlined creation of user accounts within the AD DS domain.
Therefore, the correct answer is D. dsadd.
