Which automation level setting allows more control during VM placement and requires manual migration recommendations?

The choice that allows more control during VM placement and requires manual migration recommendations is Manual. This setting implies that all decisions regarding virtual machine placement and migration must be made by the user or administrator, providing the highest level of oversight and precision in managing VM resources.

In a Manual automation level, the administrator must evaluate the needs of the workloads and make informed decisions about where to place VMs based on performance requirements, resource availability, and other operational considerations. This setting is particularly useful when specific configurations or business policies dictate precise resource allocation practices.

In contrast, other automation levels such as Fully Automated, Partially Automated, and Automatic with reservations allow for varying degrees of automation in resource management. These settings typically utilize predefined algorithms or policies to handle VM placement and migrations without requiring administrative intervention beyond the initial configuration, limiting the control that an administrator might want to exert over the resources. This makes Manual the optimal choice when detailed oversight and recommendations are necessary.
