Who determines if domain users can create individual user memberships using their corporate email address?

The correct answer indicates that DocuSign administrators are the ones responsible for determining whether domain users can create individual user memberships using their corporate email addresses. This responsibility typically falls within the scope of administrative privileges in various software platforms, where administrators have the authority to set policies and permissions for user accounts.

Administrators can configure settings related to user account creation, including who is allowed to use their corporate email addresses for creating additional accounts. This can be crucial for maintaining security and compliance within an organization. By controlling these permissions, administrators ensure that only authorized individuals have the ability to create new user memberships, which helps protect sensitive corporate data and supports the organization’s overall security policies.

In contrast, the other choices do not align with the responsibility of setting these permissions. User account holders, while they may have the ability to manage their user settings, do not have the authority to dictate policies for creating accounts. The corporate IT department might enforce and implement these policies but ultimately, it is the responsibility of DocuSign administrators to define and control user membership creation permissions. External auditors typically do not have a role in setting up or controlling user creation functionalities within the software; their focus is more on compliance checks and assessments rather than active management of user accounts.
