You have on-premises servers that run Windows Server. What should you implement to manage the servers by using the Azure portal?

Azure Arc is a hybrid cloud service that extends Azure management and services to any infrastructure, including on-premises servers. By installing the Azure Connected Machine agent on your on-premises Windows Servers, they are projected as resources within Azure. This allows you to manage, govern, and secure them directly from the Azure portal using familiar Azure tools like Azure Policy, Microsoft Defender for Cloud, and Azure Monitor, providing a single, unified management plane for both cloud and on-premises resources.

A. Azure Kubernetes Service (AKS): This is a managed container orchestration service for deploying and scaling containerized applications, not for managing the underlying on-premises server operating systems via the Azure portal.

C. Docker: This is a platform for building and running applications in containers. It is a technology that can run on a server but does not provide a mechanism to manage the server from Azure.

D. role-based access control (RBAC): This is an authorization system used to manage access permissions to Azure resources. While you would use RBAC on Arc-enabled servers, it does not provide the core functionality to connect them to Azure.

In the "What is Azure Arc-enabled servers?" section, it states, "Azure Arc-enabled servers lets you manage Windows and Linux physical servers and virtual machines hosted outside of Azure, on your corporate network, or other cloud provider."

2. Microsoft Learn. "Describe Azure Arc." AZ-900: Describe Azure management and governance. Accessed May 22, 2024. This module explains, "Azure Arc is a set of technologies that helps you manage your cloud environment... by projecting your existing non-Azure resources into the Azure Resource Manager."

3. Microsoft Learn. "What is Azure role-based access control (Azure RBAC)?" Azure RBAC Documentation. Accessed May 22, 2024. The overview section clarifies that Azure RBAC is for managing "who has access to Azure resources, what they can do with those resources, and what areas they have access to." This confirms it is an authorization system, not a hybrid connectivity solution.
