You have two Windows Server 2019 VMs (VM1 and VM2) and are creating an Update Management deployment named Update1 in Azure Automation. Update1 must automatically apply updates to VM1 and VM2 and automatically include any new Windows Server 2019 VMs. What should you include in Update1?

A dynamic group query is the correct choice because it allows you to define criteria (like operating system and version) that automatically include existing and future VMs matching those criteria in the Update Management deployment. This ensures that new Windows Server 2019 VMs are automatically managed without manual intervention. Security groups (whether Assigned or Dynamic Device) are used for managing access to resources, not for defining the scope of an Update Management deployment. While Dynamic Device groups can automatically include devices, they are not directly integrated into Azure Automation Update Management for defining the target scope in this manner. A Kusto Query Language (KQL) query is used for log analytics and data exploration, not for defining the scope of an Update Management deployment.
