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 recommend a Windows update strategy for the new branch office. What should you
recommend doing in the new branch office?
A.
Deploy WSUS in replica mode. Configure updates to be stored on the new WSUS server.
B.
Deploy WSUS in autonomous mode. Configure updates to be stored on the new WSUS server.
C.
Deploy WSUS in replica mode. Configure the WSUS clients to retrieve updates from Microsoft
Update.
D.
Deploy WSUS in autonomous mode. Configure the WSUS clients to retrieve updates from
Microsoft Update.
Explanation:
New office has a 2MMbps link to the internet and only a 512Kbps link to HQ. so configuring WSUS to
update from MS Update will meet the requirement to minimize WAN Link utalization. Making the
WSUS server a replica will meet the requirement to minimize the administrative effort to approve
updates as all updates would be approved in HQ and this approval would be replicated out to the
branch offices.

Replica mode (centralized administration)In replica mode, an upstream WSUS server shares updates, approval status, and computer groups
with downstream servers. Downstream replica servers inherit update approvals and are not
administered separately from the upstream WSUS server.
The following image shows how you might deploy replica WSUS servers in a branch office
environment.
