RG1 is a resource group that contains Vnet1, VM0, and VM1.

Azure policy definition Antimalware
Incorrect Answers:
Append:
Append is used to add additional fields to the requested resource during creation or update. A common example is adding tags on resources such as costCenter or specifying allowed IPs for a storage resource.
Deny:
Deny is used to prevent a resource request that doesn't match defined standards through a policy definition and fails the request.
Box 2: The Create a Managed Identity setting
When Azure Policy runs the template in the deployIfNotExists policy definition, it does so using a managed identity. Azure Policy creates a managed identity for each assignment, but must have details about what roles to grant the managed identity.
