Case Study: 2
Contoso, Ltd.
Scenario:
COMPANY OVERVIEW
Contoso, Ltd. is a consulting company that has a main office and two branch offices. The
main office is located in Johannesburg. The branch offices are located in Brisbane and
Montreal. The Johannesburg office has 400 users. Each branch office has 100 users.
PLANNED CHANGES
Contoso plans to open a new branch office. The new office will have a 512-Kbps connection
to the Montreal office and a 2-Mbps connection to the Internet. The new branch office will
have a domain controller, a DirectAccess server, a file server, and a Web server. All branch
office servers will be virtualized. Contoso plans to implement role-based access control for
all new virtual machines (VMs) deployed on Hyper-V servers.
In the new branch office, a user named User1 must be permitted to perform only the
following actions on the Hyper-V server:
• Start the VMs.
• View the configuration of the VMs.
EXISTING ENVIRONMENT
All servers run Windows Server 2008 R2. All client computers run Windows 7 Enterprise.
The main office has multiple file servers. Each branch office has one file server. Each file
server has two hard disks. One disk has the server’ s operating system installed and the other

disk stores data files. File server backups are performed regularly. The main office has a
Windows Server Update Services (WSUS) server. All client computers are configured to
receive updates from the WSUS server. The main office connects to each branch office by
using a 512-Kbps WAN link.
Existing Active Directory/Directory Services
The network contains a single Active Directory domain named contoso.com. An Active
Directory site exists for each office. Each Active Directory site contains three subnets. Each
subnet contains client computers.
The main office has two domain controllers. Each branch office has one domain controller.
REQUIREMENTS
Storage Requirements
Contoso must meet the following storage requirements:
• Improve data availability on the file servers.
• Improve the performance of the file servers.
• Limit each user’s storage space on the file servers to 2 GB.
• Prevent users from storing audio and video files on the file servers.
• Provide additional storage on the file servers without causing downtime.
• Enable users to access the previous versions of all the files stored on the file servers.
Technical Requirements
Contoso must meet the following technical requirements:
• Minimize the potential attack surface.
• Minimize WAN link utilization between the offices.
• Minimize the number of server licenses purchased.
• Minimize server downtime caused by Applying updates.
• Minimize the amount of administrative effort required to approve the updates.
• Minimize the amount of time it takes for users in the branch offices to access files on
the file servers in the main office.
Problem Statements
Users in the accounting department use a custom Application named App1. The
configurations for App1 can only be changed by editing the registry. Currently, a technician
must visit each client computer in the accounting department to change the App1
configurations.

You need to identify which operating system must be installed on the HyperV server in the new
branch office. Which operating system should you identify?

A.
a Server Core installation of Windows Server 2008 R2 Enterprise

B.
a Server Core installation of Windows Server 2008 R2 Standard

C.
Windows Server 2008 R2 Enterprise

D.
Windows Server 2008 R2 Standard

Explanation:

Hyper-V has specific requirements. Hyper-V requires an x64-based processor, hardware-assisted
virtualization, and hardware data execution prevention (DEP). Hyper-V is available in x64-based
versions of Windows Server 2008—specifically, the x64-based versions of Windows Server 2008
Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter technical

requirements include minimizing attach surface, Server Core achieves this. so should you use
Enterprise or Standard as Hyper V can be implemented on both x64 versions?

1 Windows Server 2008 Standard, Enterprise, and Datacenter are also offered in “without Hyper-V”
editions that do not include the hypervisor technology.
2 When customers exercise the maximum number of OS instances permitted by the server license,
the physical OS instance may not be used to run any workload beyond hosting the virtual machines.
3 A single package contains both 32-bit and 64-bit versions. The server license grants the customer
the option to use either the 32-bit version or the 64-bit version of the software.
4 Supports hot addition of memory, but not hot replacement of memory, nor hot add or
replacement of processors.
5 Use of Windows Server 2008’s new Terminal Services Gateway capability is limited to 250
connections.
6 Includes restrictions limiting scalability.
7 Volume licensing customers typically receive additional discounts of 10% to 30%.
8 Client Access Licenses (CALs) retail for US$40 apiece but are offered to volume customers for as
much as 50% off. External Connectors are available only via volume licensing programs. Pricing for
an External Connector starts at approximately US$1,800 in the least-discounted programs
Under the planned changes it states that each branch will have one DC, a DirectAccess Server a File
Server and a Web Server and that all branches will be virtualised. therefore you will be running 4
VMs Windows server 2008 Enterprise allows the running of 4 VMS on one license
So the answer is A becase Server core reduces the surface attack area and virtualization on
Enterprise server will meet the VM and licensing requirements
