What migration option allows you to move a VM to another host without moving its storage?

The option that allows you to move a VM to another host without transferring its storage is indeed related to the concept of migrating the compute resource of a VM independently from its associated storage. When you select a compute resource only migration, the virtual machine's compute resources are directed to another host, while the storage remains unchanged on its original datastore. This results in seamless migration of VM workloads for load balancing or maintenance purposes while ensuring that the data remains intact and accessible in its original storage location.

In contrast, other migration methods such as Storage vMotion involve both the movement of a VM and its associated storage to a different datastore, which is not the requirement in this context. A full migration typically refers to both compute and storage being moved simultaneously. Virtual device migration usually pertains to the transferring of virtual hardware devices rather than the VM itself or its storage. Thus, focusing solely on relocating the VM's compute resources while retaining its storage is why the selected option is correct.
