Which two features provide physical path resiliency from a Windows 2016 server to an iSCSI LUN on a 12-
node ONTAP cluster? (Choose two.)

A.
broadcast domains

B.
MPIO

C.
failover groups

D.
ALUA

Explanation:
Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop
multipath solutions that contain the hardware-specific information needed to optimize connectivity with their
storage arrays. These modules are called device-specific modules (DSMs). The concepts around DSMs are
discussed later in this document.
MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached
SCSI (SAS) interfaces in Windows Server.
Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSIconcepts and commands that define path prioritization for SCSI devices.
