On which operating systems is Azure Arc supported? Select three.

Azure Arc is a service that extends Azure management capabilities to servers, whether they're on-premises or in other cloud environments. It supports a variety of operating systems, allowing users to manage diverse environments from a single control plane.

The correct answer includes operating systems that are actively supported and compatible with Azure Arc for management purposes. AlmaLinux, Red Hat Enterprise Linux, and SUSE Linux all align with Azure's strategy to offer hybrid cloud solutions and are recognized for their capabilities within the Azure ecosystem.

Windows Server 2008 R2, on the other hand, is not supported for Azure Arc. This operating system is considered outdated and is no longer receiving mainstream support from Microsoft, which limits its compatibility with newer Azure services and features. For those looking to leverage Azure Arc effectively, using modern, supported operating systems is essential.
