CORRECTED (Previously C) 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.

B is correct.
Because it says you have 20 iSCSI devices which will be providing iSCSI services, so iSNS can be used as a directory to minimize effort.
Not A, it never says you will be using MS iSCSI target or mentions any servers which will be hosting iSCSI (just the non MS devices).

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 $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.

in the end is A??B

Answer: B
The only reason I am not picking A is because we are using “iSCSI storage appliances”. Generally speaking an appliance is a custom image or device that would be configured to provide specific services. As such it would not be unreasonable to assume the appliances are not Windows devices, and even if they are it would be reasonable to assume that the iSCSI Target role was already installed on them.
