Which two components are part of storage I/O multipathing on ESXi? (Choose two.)

A.
SATP

B.
VASA

C.
PSP

D.
VAAI

Explanation:
The NMP associates a set of physical paths with a specific storage device, or LUN. The specific details of
handling path failover for a given storage array are delegated to a Storage Array Type Plug-In (SATP). The
specific details for determining which physical path is used to issue an I/O request to a storage device are
handled by a Path Selection Plug-In (PSP). SATPs and PSPs are sub plug-ins within the NMP module.
