PLANNED CHANGES
Blue Yonder Airlines plans to implement the following changes:
• Upgrade all client computers to Windows 7.
• Deploy a virtualization solution for the company’s developers.
• Implement coexistence between the users in Fabrikam and the users in Blue Yonder Airlines.
EXISTING ENVIRONMENT

One user in each office runs a point-of-sale (POS) application named Appl. App 1 requires access to a
local USB device and only runs on Windows XP Service Pack 3 (SP3).
Blue Yonder Airlines has a finance department.
Business Goals
Blue Yonder Airlines plans to acquire a company named Fabrikam, Inc. Fabrikam has an Active
Directory forest named fabrikam.com. Fabrikam.com contains only domain controllers that run
Windows Server 2003 Service Pack 2 (SP2).
Fabrikam.com contains multiple Web servers that are secured by using certificates. All server
certificates are issued by the internal CA of Fabrikam.
Existing Active Directory Environment

The network contains an Active Directory forest named blueyonderairlines.com. The forest contains
a single domain.
The domain contains domain controllers that run Windows Server 2008. The domain controllers are
configured as shown in the following table.
The forest contains a single Active Directory site. A subnet object is defined for each office.
The forest contains a certification authority (CA).
Existing Network Infrastructure
Each office has a file server and a print server.
The main office has a file server named Server1. The shared folders on Server1 are configured as
shown in the following table.

Blueyonderairlines.com has a standalone DFS root named \\serverl\corp that contains a link named
sales. Replicas of \\serverl\corp\sales are deployed in each office.
Current Administration Model
Administrators manage the Active Directory objects by using the Active Directory module for
Windows Power Shell.
TECHNICAL REQUIREMENTS
Blue Yonder Airlines must meet the following requirements for coexistence between Blue Yonder
Airlines and Fabrikam:

• Only specific users in Fabrikam must be allowed to access specific shares in
blueyonderairlines.com.
• Users in Blue Yonder Airlines must be able to access the secure Web servers in fabrikam.com
without receiving a warning message about the certificate.
• All administrators in Blue Yonder Airlines must be able to administer Active Directory objects
in fabrikam.com by using their default administrative tools.
The corporate security policy states that when a domain controller fails, all references to the domain
controller must be permanently removed from the domain before the domain controller is replaced.
Blue Yonder Airlines must meet the following virtualization requirements:
• Ensure that each developer can create and manage his own virtual machine (VM).
• Prevent the developers from configuring the settings of other developers’ VMs.
• Prevent the developers from creating VMs that use more than 2 GB of memory,
• Minimize the amount of bandwidth used when users access files over WAN links.
