Your network contains a single Active Directory domain.
The domain contains a server named Server1 that runs Windows Server 2008 R2.
An administrator connects Server1 to an iSCSI target.
You restart Server1 and discover that the iSCSI target is not connected.

You need to ensure that Server1 automatically connects to the iSCSI target when you restart the server.

What should you do?

A.
From the iSCSI Initiator console, add Server1 as a target portal.

B.
From the iSCSI Initiator console, add the target to the favorite targets list.

C.
From the Storage Explorer console, add a new iSCSI initiator.

D.
From the Storage Explorer console, disable the default Discovery Domain Set.

Explanation:
Favorite Targets properties

By marking a target as a favorite target, Microsoft iSCSI Initiator configures software and hardware initiators to always attempt to reconnect to a target whenever the computer is rebooted. The login information that is needed to connect to the favorite targets (for example, Challenge-Handshake Authentication Protocol (CHAP) secrets, portal information, etc.) is captured when you log in, and is saved by the software and hardware initiators in non-volatile storage. Hardware initiators can initiate a reconnection early in the boot process while the Microsoft Software Initiator kernel mode driver initiates a reconnection as soon as the Windows TCP/IP stack and the Microsoft iSCSI Initiator service loads.

Favorite targets
Microsoft iSCSI Initiator supports favorite (formerly called persistent) targets. By using common APIs and UI, Microsoft iSCSI Initiator can configure software and hardware initiators to always reconnect to a target when the computer is rebooted. Consequently, this requires that the devices on the target are connected to the computer at all times. The logon information that is needed to connect to the favorite targets (for example, CHAP secrets and portal) is captured when the persistent logon is performed by the administrator and saved by the software and hardware initiators in non-volatile storage. Hardware initiators can initiate reconnection early in the boot process, but the kernel-mode driver in Microsoft iSCSI Initiator initiates reconnection when the Windows TCP/IP stack and Microsoft iSCSI Initiator load.
