An administrator is considering deploying a new storage array for a vSphere 5 implementation. If the array supports the vStorage APIs for array integration (VAAI), which two tasks can be performed directly by the array? (Choose two)
A.
creating VMFS datastores
B.

C.

D.

Answer: C and B
http://pubs.vmware.com/vsphere-4-esx-vcenter/topic/com.vmware.vsphere.server_configclassic.doc_41/esx_server_config/managing_storage/c_hardware_acceleration_requirements.html
When the hardware acceleration functionality is supported, the host can get hardware assistance and perform the following operations faster and more efficiently:
■
Migration of virtual machines with Storage vMotion
■
Deployment of virtual machines from templates
■
Cloning of virtual machines or templates
■
VMFS clustered locking and metadata operations for virtual machine files
■
Writes to thin provisioned and thick virtual disks
■
Creation of fault-tolerant virtual machines
