Case Study #1, CONTOSO, LTD
Background
Contoso, Ltd is a military and aerospace research company that has approximately 16,000 employees.
You have been asked to provide consulting services for the design and implementation of the company’s enterprise Active Directory.
The company’s primary business since 1953 has been military research. However, in 1997 the company purchased an aerospace company and added aerospace research to its business. Although the corporate offices for both companies have been consolidated, a separation between divisions still exists. There are separate chief information officers (CIOs) for the military and aerospace divisions. The two CIOs report
to the chief executive officer (CEO) of Contoso, Ltd. and have equal authority. The CIOs have complete autonomy in most areas of IT. Each CIO has his own budget.
The CIOs have agreed to consolidate their efforts in some areas. The military division CIO is
responsible for providing IT services to corporate departments such as human resources and accounting. The military division CIO is also responsible for providing an enterprise wide messaging infrastructure. The military division incurs all costs for supporting and maintaining the messaging infrastructure. A fee
for each mailbox is assigned and internally charged against the aerospace budget on a quarterly basis. In return, the military division CIO provides a guaranteed uptime of 99 percent to the aerospace.
The headquarters office for Contoso, Ltd. is located in New York. Approximately 3,700 employees
work at headquarters. Executives from both divisions work in the headquarters office. Contoso, Ltd. also has locations in the following cities:
Military Division:
• Boston (2,500 users)
• Atlanta (1,300 users)
Aerospace Division
• Seattle (5,800 users)
• San Francisco (1,200 users)
• San Diego (700 users)
Existing Environment:
Contoso, Ltd. has a single registered domain name of Contoso.com hosted on a UNIX DNS server. Currently, the A (host) records for all UNIX-based devices and web servers are statically registered on
the DNS server.
The military division currently provides e-mail services to the entire company.
WAN Architect Interview
I manage the entire WAN. Atlanta, Boston, and Seattle have T1 lines to New York. San Francisco and
San Diego have T1 lines to Seattle. There is a 56-Kbps connection between San Francisco and San Diego for redundancy. We have a single connection to the Internet in New York. A firewall provides protection between our network and the Internet connection. All of my WAN equipment is stored in secure data centers in each location
Aerospace Division CIO Interview
We currently outsource our messages application to the military division. They have guaranteed us an uptime of 99 percent, but it seems like e-mail is always down. My primary network administration team
is located in Seattle. There are technical people in each location to provide on-site support for users in my division.
Business Requirements
Military Division CIO Interview
We have had many problems in the past maintaining a stable messaging infrastructure. We plan to

migrate to Microsoft Exchange 2000 to take advantage of the clustering technologies provided. We hope
to be able to provide a service level of 99.995 percent after the migration is complete.
Aerospace Division CIO Interview
My responsibly is to the users in the aerospace division. I cannot afford to depend on another division to provide my network operating system (NOS) services. I have been told that I must continue to outsource our e-mail services to the military division. I have been assured that e-mail services will be upgraded
soon to increase reliability and that I will gain control over my users’ mailboxes
My office is in New York and I want to ensure that I have the fastest possible logon speed.
Aerospace Division IT Manager Interview
Because the military division domain contains the corporate departments, we must have access to
resources in the military division domain. One important application that we must be able to access at all times is a Microsoft SQL server database located in New York. There are currently no resources that the military division needs to access in our domain. All of our user and client computer accounts, including those of our CIO, will be located in our domain. One problem that we have had several times in the past
is that the UNIX DNS server has gone offline. When that happened, we were not able to access many of these important resources.
We plan to store some sensitive information, such as employee payroll numbers, in Active Directory. We want to limit view access of this type of information to specific individuals. We plan to limit view access for all objects to Active Directory to authenticated users only. We also plan to create groups that
will have view access to this sensitive information.
Technical Requirements
Both CIOs have already agreed to the following design decisions. There will be two forests in the Contoso, Ltd. enterprise. One forest will contain the military division and the other will contain the aerospace division. Both of these forests will contain an empty root domain. A joint budget has already been allocated, and your consulting company will be providing the Active Directory design for both divisions. A metadirectory synchronization program will be installed in New York.
Aerospace Division IT Manager Interview
The military division has agreed to allow us to manage certain properties of our e-mail accounts directly.
I will be creating two accounts in my root domain for this purpose. These two accounts will be allowed
to modify these certain mailbox properties.
Military Division IT Manager Interview
Currently, a local site administrator is responsible for managing all user and computer accounts for each site. With the implementation of Active Directory, we will be changing the way we administer accounts. The existing site administrators will continue to manage resources. However, new teams for each department will be created in New York. These new department-based teams will manage the user
accounts in each department.
Redundancy of our root domain controllers is extremely important to me. I want to ensure that if there is
a disaster, we have an off-site copy of this root domain. A network file share located in New York
contains all human resources documents for the entire company. We will need to provide access to these documents to everyone. We also have human resources staff located in Seattle who will need to update these documents. Because the documents are large, we want to provide local copies of the documents in Seattle. We currently plan to use DFS and to replicate this share to a DFS server in the aerospace
domain. I am concerned about how we will be able to provide a single directory to our e-mail users.
Case Study #1, CONTOSO, LTD (9 Questions)

QUESTION 1
Which factor or factors in the company’s forest design decision will increase the administrative overhead of managing its enterprise NOS environment? (Choose all that apply)

A. Providing a single enterprise directory
B. Duplication in planning teams for directory deployment
C. Directory management duplication
D. Complexity relating to the separation of users and resources in different forests
E. Initiation of separate design processes
Answer: C, D Explanation:
Since there will be no automatic replication between forests internal to Active Directory, an outside package is required to keep the forests in sync. This will be done by using a metadirectory
synchronization package. Even in this situation, some care must be taken when running multiple forests. The complexity of users and resources in the different forests relate to having to establish and maintain trusts between various domains. There may even be more issues to deal with since Contoso expects to
make changes to and add to the Active Directory Schema. Incorrect Answers:
A: There really isn’t a single enterprise directory, since each forest will have its own separate enterprise directory, and keeping them synchronized can only be done by a 3rd party package.
B: Planning and initial implementation is a one time up front action. This in itself does not add to the administrative overhead since it is not ongoing. It is overhead, but extra overhead to design
and implement the system which is the cost of conversion.
E: Having separate design processes, one for each forest is also the overhead of system implementation/conversion, and is a one-time cost. It would not be considered administration overhead since it is not ongoing. When we talk about administration overhead, we are talking about ongoing maintenance of the system.

QUESTION 2
Which technical factor or factors influenced the company’s forest design decision? (Choose all that apply)

A. Network Address Translation (NAT) devices are separating domain controllers
B. None: the decision was not influenced by technical factors
C. Bandwidth is not sufficient to support a single forest
D. Firewalls are separating the domain controllers
E. The company wants to eliminate trusts between domains
F. DNS service cannot resolve name throughout the forest
Answer: B Explanation:
Lets look at the early part of the case study, specifically: “However, in 1997 the company purchased an aerospace company and added aerospace research to its business. Although the corporate offices for
