Which of these apps and services can you access with both an unmanaged and Managed...

iCloud Backup is available with a personal, unmanaged Apple Account and can also be made available with a Managed Apple Account in supported organizational deployment models. Apple documents that Account-driven Device Enrollment and User Enrollment extend Managed Apple Account services to include contacts, calendars, reminders, notes, iCloud Drive, and iCloud Backup. Therefore, option A is correct. Health and Find My are examples of services that are unavailable to Managed Apple Accounts. Apple One is a consumer subscription bundle and is not a Managed Apple Account service. Organizations can also use Apple Business Manager or Apple School Manager to control which supported iCloud services their Managed Apple Account users can access. This provides organizational control while allowing supported cloud services such as iCloud Backup where appropriate.
