Which method should be used to create user accounts efficiently in a high-turnover organization?

The choice of installing Google Cloud Directory Sync on a supported server is the best method for efficiently creating user accounts in a high-turnover organization. This tool is specifically designed to synchronize user account data between an on-premises directory (like Active Directory) and Google Workspace. By implementing Google Cloud Directory Sync, organizations can automate the process of creating new user accounts based on the information already maintained in their existing directory.

This automation streamlines user account provisioning, especially crucial for high-turnover environments where new hires are frequent. It helps ensure that user information is accurate and up-to-date without the need for manual entry, which can be prone to errors and is time-consuming. Additionally, synchronization can include changes or deletions, further ensuring that user statuses reflect the current state of employment.

In contrast, while other options may serve different purposes—such as syncing Outlook with Google Workspace or automating scripts—they do not directly address the need for efficient user provisioning from an existing directory. Thus, utilizing Google Cloud Directory Sync on a supported server stands out as the most effective solution for managing user accounts in such dynamic organizational settings.
