Yournetwork contains servers that run Windows Server 2012 R2.
The network contains a large number of iSCSI storage locations and iSCSI clients.
You need to deploy a central repository that can discover and list iSCSI resources on the network
automatically.
Which feature should you deploy?
A.
the Windows Standards-Based Storage Management feature
B.
the iSCSI Target Server role service
C.
the iSCSI Target Storage Provider feature
D.
the iSNS Server service feature
Explanation:
A)
Windows Server 2012 R2 enables storage management that is comprehensive and fully
scriptable, and administrators can manage it remotely.
A WMI-based interface provides a single mechanism through which to manage all storage, including
non-Microsoft intelligent storage subsystems and virtualized local storage (known as Storage
Spaces). Additionally, management applications can use a single Windows API to manage different
storage types by using standards- based protocols such as Storage Management Initiative
Specification (SMI-S).
B)
Targets are created in order to manage the connections between an iSCSI device and the servers
that need to access it. A target defines the portals (IP addresses) that can be used to connect to the
iSCSI device, as well as the security settings (if any) that the iSCSI device requires in order to
authenticate the servers that are requesting access to its resources.
C)
iSCSI Target Storage Provider enables applications on a server that is connected to an iSCSI target
to perform volume shadow copies of data on iSCSI virtual disks. It also enables you to manage iSCSI
virtual disks by using older applications that require a Virtual Disk Service (VDS) hardware provider,
such as the Diskraid command.
D)
The Internet Storage Name Service (iSNS) protocol is used for interaction between iSNS servers
and iSNS clients. iSNS clients are computers, also known as initiators, that are attempting to
discover storage devices, also known as targets, on an Ethernet network.
