A bare VM is required when creating a virtual desktop template on FusionAccess.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

Bare VM creation rules in FusionAccess are strict to ensure template consistency and successful provisioning:

A is true: The system disk must use Common configuration mode, not thin provisioning.

B is true: For linked-clone bare VMs, NICs are added after template creation, during desktop provisioning.

C is false: Bare VMs should use management-plane networking, not user service-plane DVS/port groups.

D is false: Thin provisioning is not allowed for the system disk of a bare VM.

Therefore, the correct answers are A and B.
