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.

the file servers in the main office.

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.

Improve the performance of the file servers.
C.
Provide additional storage on the file servers without causing downtime.
D.
Enable users to access the previous versions of all the files stored on the file servers.
Explanation:
http ://technet.microsoft.com/en-us/library/cc732422.aspx
A striped volume is a dynamic volume that stores data in stripes on two or more physical disks. Data
in a striped volume is allocated alternately and evenly (in stripes) across the disks. Striped volumes
offer the best performance of all the volumes that are available in Windows, but they do not provide
fault tolerance. If a disk in a striped volume fails, the data in the entire volume is lost.
You can create striped volumes only on dynamic disks. Striped volumes cannot be extended. You can
create a striped volume onto a maximum of 32 dynamic disks.
