Which statement is true regarding the Infrastructure Master Active Directory FSMO role?

The Infrastructure Master Active Directory FSMO role is primarily responsible for managing references to Active Directory objects that are located in other domains, particularly when it comes to group memberships. This role is crucial in multi-domain environments where groups may contain users from different domains. The Infrastructure Master ensures that group memberships are accurate and up-to-date, coordinating between domains to maintain consistency in the directory.

In contrast, the other statements do not accurately depict the functions of the Infrastructure Master role. For instance, limiting the role to one per domain controller is incorrect, as it refers to the nature of how Active Directory roles are assigned, not the specific function of the Infrastructure Master. The coordination of user password changes is handled by the Domain Naming Master and not the Infrastructure Master. Lastly, while the Infrastructure Master operates within the context of a domain, its function for coordinating group membership does not mean it is limited to one role per forest, as each domain can have its own Infrastructure Master. This multifaceted nature of the role underscores its importance in maintaining the integrity of group memberships across different domains within an Active Directory environment.
