Case Study: 4
Litware Inc
Overview
Litware, Inc. is a pharmaceutical company.
Litware has an office in Montreal. Litware has a marketing department and a research department.
Existing Environment
Network Infrastructure
The network contains a single Active Directory domain named litwareinc.com. The domain contains
1,000 physical servers that run Windows Server 2008 R2.
All of the servers are located in a leased data center that has a high-bandwidth, low-latency network.
The data center contains third-party iSCSI SAN storage devices that support an SMI-S provider.
Application Infrastructure
Users in the research department use multiple instances of a three-tier application named Appl.
App1 consists of the components shown in the following table.
The Web Server (IIS) server role, WMI providers, Windows services, Windows drivers, and web
applications will be installed on the servers that host Tier 2.
Problem Statements
Litware identifies the following issues:
• The cost of leasing data center space is increasing steadily.
• The research department users report that it takes too long to provision new instances of
Appl.
Requirements
Planned Changes
Litware plans to deploy 400 additional servers that will run Windows Server 2008 R2. The servers will
be configured as shown in the following table.
Litware also plans to deploy the following System Center 2012 components:
• Orchestrator
• App Controller
• Service Manager
• Operations Manager
• Data Protection Manager (DPM)
• Virtualization Machine Manager (VMM)
Litware plans to provide the research department users with the ability to deploy instances of Appl.
Private Cloud Infrastructure Requirements
Litware identifies the following requirements for the planned private cloud infrastructure:
• VMM must be available if a server or a service fails.
• Virtual machines must be provisioning by using SAN copy cloning.
• The implementation of App Controller must support single sign-on.
• The implementation of Service Manager must support French and English.
• The implementation of VMM must support the provisioning of virtual machines by using SAN
copy.
• Virtual machines hosted on Hyper-V failover clusters must remain available during the
installation of Windows updates.
• Physical servers that have workloads that are suitable for a virtualized environment must be
virtualized. Performance data must be taken into account when identifying which servers must be
virtualized.
Private Cloud Integration Requirements
Litware identifies the following requirements for integrating the System Center 2012 components:
• Incidents in Service Manager must be resolved automatically, whenever possible.
• Alerts generated by Operations Manager must trigger incidents in Service Manager.
• Operations Manager alerts triggered by VMM events must be remediated automatically,
whenever possible.
• All of the Orchestrator components responsible for executing the activities of Service
Manager workflows must be highly available.
Private Cloud Services Requirements
Litware identifies the following requirements for managing services in the private cloud:
• App1 must be deployed by using a VMM service template.
• The Tier 2 of App1 must be deployed as a highly available virtual machine.
• The research department users must use App Controller to deploy virtual machines and
services.
• The virtual machines deployed by the research department users must be hosted on servers
in the research department.
• The virtual machines in Tier 1 of App1 must be configured as cluster nodes by using the
Network Load Balancing (NLB) feature.
• A web application named WA1 in Tier 2 of App1 must use a connection string that points to
a Microsoft SQL Server database in Tier 3 of Appl.
• The software components included in Tier 2 of App1 must be deployed as Microsoft Server
Application Visualization (Server App-V) packages, whenever possible.

DRAG DROP
You need to recommend a storage fabric configuration for VMM. The solution must meet the
requirements for the planned private cloud infrastructure. Which three actions should you
recommend performing in sequence? (To answer, move the appropriate three actions from the list
of actions to the answer area and arrange them in the correct order.)
Answer: 
Explanation:
The answer is correct. Look this link

First of all i’m going to show why the answer is incorrect.
1- We need “Microsoft iSCSI Software Target ” when we want to turn a server running Windows Server 2008 R2 into a Storage device supports iSCSI protocol. But the case study says “The data center contains third-party iSCSI SAN storage devices that support an SMI-S provider”. As we see, we have a iSCSI SAN storage that support SMI-S provider.
2- We can not “Allocate a storage pool to a host group” unless the storage has already been added. After “Adding” a storage we can allocate the storage to the host.
So the correct answer should be like that:
1- First we need to “Add Storage Device”
2- After adding a storage we should “Configure Storage Array” for configuring few settings
3- After adding and configuring we have to “Allocate a storage pool to a host group” otherwise we can create LUNs
Notice that we no need “Configuring the iSCSI initiator” because VMM use SMS-I provider to find, connect and manage SAN storge.
For more information look at this well-explained video about this: https://channel9.msdn.com/Shows/TechNet+Radio/TechNet-Radio-Part-4-Building-a-Private-Cloud-with-System-Center-2012-Service-Pack-1–Configuring-St#time=7m03s (Specially [13:29] )

I agree. Should be Add, Configure, Allocate

At 15:05 the video says: We want to make sure first that we are physically connected, we are zoned into that storage. In other words, that all of that hosts can see the storage across the storage network.
For this you have to configure the iSCSI initiator, then you add a storage device, and then you allocate a storage pool to a host group.
You have third party iSCSI boxes which need some configuration probably, but it seems to me that is outside the scope of the exam. A lot of confusion in this question.

I agree with this. Configure iSCSI, Add storage device, Allocate storage pool.
