You have multiple domains in a single Google Workspace account. How can you provision users in a specific sub-domain?
The 'Add user' dialog includes a domain dropdown listing every verified domain in the account, so selecting the target sub-domain creates the user there directly. This satisfies provisioning into a specific sub-domain without separate admin accounts.
Why this answer
When adding a user in the Google Workspace Admin console, the 'Add user' dialog includes a dropdown menu that lists all verified domains and sub-domains in the account. Selecting the desired domain from this dropdown ensures the new user's primary email address is created under that specific domain. This is the standard, direct method for provisioning users in any domain or sub-domain without altering the primary domain or using aliases.
Exam trap
GWS-ADMIN often tests the misconception that organizational units (OUs) are used to assign domains to users, when in fact OUs are for policy management and the domain is selected explicitly during user creation.
How to eliminate wrong answers
Option A is wrong because renaming the primary domain changes the primary domain for the entire account and does not provision users in a sub-domain; it also has significant side effects on existing users and services. Option B is wrong because a group alias is used to create an additional email address for a group, not to provision individual user accounts in a sub-domain. Option C is wrong because an organizational unit (OU) is a container for applying policies and settings to users, not a mechanism for assigning a domain to a user; OUs do not determine a user's email domain.
