ACME Tools has a vSphere 5.x deployment with an older iSCSI storage array. The administrator is considering adding an additional array which will include support for the vStorage APIs for Array Integration (VAAI). Which two tasks would be completed in a reduced period of time if the new array was added? (Choose two.)
A. creating VMFS datastores on the new array
B. creating fault tolerant virtual machines on the new array
C. migrating virtual machines using Storage vMotion between the arrays
D. writes to thin provisioned virtual disks on the new array
Correct Answer: BD

"Creating fault tolerant virtual machines on the new array" is correct because VAAI uses this fundamental operation: Clone Blocks/Full Copy/XCOPY, which is used to copy or migrate data within the same physical array.
"writes to thin provisioned virtual disks on the new array" is correct because VAAI uses this fundamental operation: Thin Provisioning in ESXi 5.x and later hosts, which allows the ESXi host to tell the array when the space previously occupied by a virtual machine (whether it be deleted or migrated to another datastore) can be reclaimed on thin provisioned LUNs.
