Your network contains 20 iSCSI storage appliances that will provide storage for 50 Hyper-V hosts
running Windows Server 2012 R2.
You need to configure the storage for the Hyper-V hosts. The solution must minimize administrative
effort.
What should you do first?
A.
Install the iSCSI Target Server role service and configure iSCSI targets.
B.
Install the iSNS Server service feature and create a Discovery Domain.
C.
Start the Microsoft iSCSI Initiator Service and configure the iSCSI Initiator Properties.
D.
Install the Multipath I/O (MPIO) feature and configure the MPIO Properties.
Explanation:
Windows Server 2012 includes an iSCSI Target role that, along with Failover Clustering, allows it to
become a cost-effective and highly-available iSCSI Storage Array.
We can connect from our Hyper-V host to the iSCSI target on the storage array with the following
PowerShell command line:
New-IscsiTargetPortal –TargetPortalAddress<IP_Address or FQDN of storage array>
$target = Get-IscsiTarget
Connect-IscsiTarget –NodeAddress $target.NodeAddress
Incorrect:
Not B. Discovery Domains in an iSCSI fabric, like zones in a Fibre Channel fabric, enable you to
partition the storage resources in your storage area network (SAN). By creating and managing
Discovery Domains, you can control the iSCSI targets that each iSCSI initiator can see and log on to.
Configure iSCSI Target Server Role on Windows Server 2012
the answer is B.

C – You need to configure the Hyper-V hosts that run Windows Server 2012 R2. The Hyper-V hosts are the iSCSI Initiators and the storage appliances are the iSCSI targets.
You need the iSCSI Initiator installed first to configure the iSNS server in iSCSI Initiator tool.

Could be B – Not sure anymore, not well written question. You need to configure “the storage for hyper-v hosts”, does it mean which part of the storage? the iSCSI target or initiator? the iSNS will improve the discover of the 20 targets for the hyper-v hosts, it can be installed first, in any server I believe.

The answer is B ! (check at the bottom)

A is wrong: 20 ISCSI storage appliances (with targets) are ready for provide the storage. Any other ISCSI target is useless.
B can be useful only after the configuration of ISCSI initiators.
So the first step is:
Exam Ref 70-412: Configuring Advanced Windows Server 2012 R2 Services
Page 128:
#Enabling iSCSI Initiator
The iSCSI client component included in Windows Server is called iSCSI Initiator. iSCSI Initiator is already installed by default, but its associated service (Microsoft iSCSI Initiator service) is not running by default. Before you can begin to configure shared storage, you need to start this service and set it to start automatically in the future.
Answer C: Start the Microsoft iSCSI Initiator Service and configure the iSCSI Initiator Properties.

The correct answer should be C (hyper-v host is the client or ISCSI initiator and the ISCSI Storage appliance the ISCSI target)

Spent way too much time, trying to figure out is it A or C and my final vote goes to C.
As said by many before me:
A) 20 iSCSI storage appliances have already been configured as iSCSI Targets.
C) The iSCSI client component included in Windows Server is called iSCSI Initiator. iSCSI Initiator is already installed by default, but its associated service (Microsoft iSCSI Initiator service) is not running by default. Before you can begin to configure shared storage, you need to start this service and set it to start automatically in the future.
You can perform this task just by opening iSCSI Initiator in the Tools menu of Server Manager.
To configure a local storage server to provide logical disks to a remote server through iSCSI, perform the following steps. (These steps assume that the iSCSI Target Server is already installed on the storage server and that iSCSI Initiator is already enabled on the remote server.)
1. In Server Manager on the storage server, create a new iSCSI virtual disk by using the New iSCSI Virtual Disk Wizard. You will be prompted to add the new virtual disk to an iSCSI target. If no target is yet available, you will be prompted to create a new target in the wizard and to add iSCSI initiators to the target.
2. Configure the iSCSI Initiator on the remote server to connect to the iSCSI target.
3. When the new disk or disks appear in Server Manager on the remote server, bring them online, initialize them, and then create volumes as needed.
B) That would be the next step.
-As per MS Exam Ref. 70-412…. iSNS Server is an installable Windows Server feature. iSNS acts as a central repository of iSCSI components that are available on a network. iSNS generally works like this: First, you register iSCSI initiators and targets with the iSNS server. You then configure each iSCSI Initiator with the address of the iSNS server. After that, initiators are able to query iSNS for a list of targets available on the network.
PAY ATTENTION To the part…First, you register iSCSI initiators….

I think the answer is B. What should you do first? You have to install the isns feature before you can register the iscsi initiators with that service.
