Your company has a private cloud that is managed by a server named Server1. Server1 has System
Center 2012 Virtual Machine Manager (VMM) installed. You add a Hyper-V host named Server2 to
the server fabric. Server2 is connected to a SAN named SAN1 by using Fiber Channel connections.
You need to optimize access to the LUNs in SAN1 from Server2. What should you do first?

A.
install the Multipath I/O (MPIO) feature on Server1.

B.
Configure Server2 to connect to SAN1 by using an iSCSI channel.

C.
install the Multipath I/O (MPIO) feature on Server2.

D.
Configure Server1 to connect to SAN1 by using an iSCSI channel.

The Multipath I/O (MPIO) feature must be added on each host that will access the Fibre Channel or
iSCSI storage array. You can add the MPIO feature through Server Manager. If the MPIO feature is
already enabled before you add a host to VMM management, VMM will automatically enable MPIO
for supported storage arrays by using the Microsoft provided Device Specific Module (DSM). If you
already installed vendorspecific DSMs for supported storage arrays, and then add the host to VMM
management, the vendor-specific MPIO settings will be used to communicate with those arrays.
