Free Microsoft 365 Fundamentals MS-900 Practice Question

Microsoft 365 E3 is the correct choice because it combines Office 365 productivity apps with advanced security features and device management capabilities in one license. This subscription includes Windows 10 Enterprise, Office 365 E3, and Enterprise Mobility + Security (EMS) E3, fulfilling all the company's requirements. Office 365 E3 provides productivity apps but lacks the full suite of security and device management features. Office 365 E5 includes additional security features over E3 but does not include Windows 10 Enterprise or EMS. Windows 10 Enterprise E3 offers the operating system with some security features but does not include productivity apps or comprehensive device management.
