A SOHO customer purchases a Windows 11 computer.

The correct answer is D. The computer operating system is Home edition . Windows Home editions are intended for consumer and basic home use and do not support joining a traditional Windows domain. The All-in-One Exam Guide clearly states that Windows Home systems cannot become part of a domain and that a system needs Windows Pro or a higher edition for domain membership. The Mike Meyers/Mark Soper material also shows that Windows Home cannot use a Windows domain, while Windows Pro can, and explains that Windows 10 Pro is the most basic edition that supports joining a Windows domain. This same edition limitation applies to Windows 11 in the A+ exam context. Updating Windows, changing network settings, or restarting for Group Policy will not enable domain joining on Home edition. The correct fix would be upgrading to Windows Pro or another domain-capable edition.
