B and D are correct.
SMP is Symetrical Multi Processing. With FT you are only allowed 1 vCPU.
vSphere Features Not Supported with Fault Tolerance
The following vSphere features are not supported for fault tolerant virtual machines.
■
Snapshots. Snapshots must be removed or committed before Fault Tolerance can be enabled on a virtual machine. In addition, it is not possible to take snapshots of virtual machines on which Fault Tolerance is enabled.
■
Storage vMotion. You cannot invoke Storage vMotion for virtual machines with Fault Tolerance turned on. To migrate the storage, you should temporarily turn off Fault Tolerance, and perform the storage vMotion action. When this is complete, you can turn Fault Tolerance back on.
■
Linked clones. You cannot enable Fault Tolerance on a virtual machine that is a linked clone, nor can you create a linked clone from an FT-enabled virtual machine.
■
Virtual Machine Backups. You cannot back up an FT-enabled virtual machine using Storage API for Data Protection, VMware Data Recovery, or similar backup products that require the use of a virtual machine snapshot, as performed by ESXi. To back up a fault tolerant virtual machine in this manner, you must first disable FT, then re-enable FT after performing the backup. Storage array-based snapshots do not affect FT.
