1Fabrikam, Inc
Overview
Fabrikam, Inc., is a pharmaceutical company located in Europe. The company has 5,000 users. The
company is finalizing plans to deploy an Exchange Server 2013 organization.
The company has offices in Paris and Amsterdam.
Existing Environment
Active Directory Environment
The network contains an Active Directory domain named fabrikam.com. An Active Directory site
exists for each office.
Network Infrastructure
The roles and location of each server are configured as shown in the following table.

Client computers run either Windows 7 or Windows 8 and have Microsoft Office 2010 installed.
The Paris office uses the 192.168.1.0/24 IP range. The Amsterdam office uses the 192.168.2.0/24 IP
range.
The offices connect to each other by using a high-speed, low-latency WAN link. Each office has a 10-
Mbps connection to the Internet.
Planned Exchange Infrastructure
The company plans to deploy five servers that run Exchange Server. The servers will be configured as
shown in the following table.

The company plans to have mailbox databases replicated in database availability groups (DAGs). The
mailbox databases and DAGs will be configured as shown in the following table.

DAG1 will use FS1 as a file share witness. DAG2 will use FS3 as a file share witness.
You plan to create the following networks on each DAG:
• A dedicated replication network named DAGNET1
• A MAPI network named DAGNET2
All replication traffic will run on DAGNET1. All client connections will run on DAGNET2. Client
connections must never occur on DAGNET1. Replication traffic must only occur on DAGNET2 if
DAGNET1 is unavailable.
Each Exchange Server 2013 Mailbox server will be configured to have two network adapters.
The following two mailbox databases will not be replicated as part of the DAGs:
• A mailbox database named AccountingDB that is hosted on EX1
• A mailbox database named TempStaffDB that is hosted on EX4
EDGE1 will have an Edge Subscription configured, with both EX1 and EX2 as targets.
Requirements
Planned Changes
An external consultant reviews the Exchange Server 2013 deployment plan and identifies the
following areas of concern:
• The DAGs will not be monitored.
• Multiple Edge Transport servers are required to prevent the potential for a single point of
failure.
Technical Requirements
Fabrikam must meet the following technical requirements:
• Email must be evaluated for SPAM before the email enters the internal network.
• Production system patching must minimize downtime to achieve the highest possible service
to users.
• Users must be able to use the Exchange Control Panel to autonomously join and disjoin their
department’s distribution lists.
• Users must be able to access all Internet-facing Exchange Server services by using the names
of mail.fabrikam.com and autodiscover.fabrikam.com.
The company establishes a partnership with another company named A. Datum Corporation. A.
Datum uses the SMTP suffix adatum.com for all email addresses. Fabrikam plans to exchange
sensitive information with A. Datum and requires that the email messages sent between the two
companies be encrypted. The solution must use Domain Security.
Users in the research and development (R&D) department must be able to view only the mailboxes
of the users in their department from Microsoft Outlook. The users in all of the other departments
must be prevented from viewing the mailboxes of the R&D users from Outlook.
Administrators plan to produce HTML reports that contain information about recent status changes
to the mailbox databases.
Fabrikam is evaluating whether to abort its plan to implement an Exchange Server 2010 Edge
Transport server and to implement a Client Access server in the Paris office instead. The Client
Access server will have anti-spam agents installed.

Contoso Ltd
Overview
General Overview
Contoso, Ltd., is a scientific research and supply company that has offices along the east coast of
North Americ
a. The company recently completed an upgrade to Exchange Server 2013.
Physical Locations
The company has three sales offices and a research office. The sales offices are located in Atlanta,
New York, and Montreal. The research office is located in Miami.
Existing Environment
Active Directory Environment
The network contains one Active Directory forest named contoso.com. The Miami office has its own
domain named research.contoso.com.
Each office is configured as an Active Directory site. Each site contains two domain controllers that
run Windows Server 2008 R2 x64. All of the FSMO roles for contoso.com are owned by a domain
controller in the New York site. All of the FSMO roles for the research.contoso.com domain are
owned by a domain controller in the Miami site.
One domain controller in each site is configured as a global catalog server. All of the domain
controllers are configured as DNS servers.
The functional level of the forest and domains is Windows Server 2008 R2.
Network Infrastructure
All client computers are configured to connect to the DNS servers in their respective office only.
Contoso.com has a standalone certification authority (CA) on a server that runs Windows Server
2008 R2.
All offices connect to the New York office by using a high-speed WAN link.
Email Infrastructure
The Exchange Server 2013 organization contains four servers in the New York office. The servers are
configured as shown in the following table.

All external access for the contoso.com organization is provided through an Internet link at the New
York office. Load balancing is provided by using DNS round robin. All inbound and outbound email
for the domain is routed through a mail appliance in the New York office.
The Exchange Server 2013 organization contains four servers in the Atlanta office. The servers are
configured as shown in the following table.

The file share witness for NY-DAG is on a file server in the Atlanta office.
The Exchange Server 2013 organization contains two servers in the Montreal office and two servers
in the Miami office. The servers are configured as shown the following table.

All external access to the organization of the research.contoso.com domain is provided through the
Internet link at the Miami office. Load balancing is provided by using DNS round robin. All inbound
and outbound email for the domain goes through an email appliance in the Miami office.
All Exchange Server 2013 servers run Windows Server 2012 Standard.
All users have Windows Phone devices that connect to the Exchange organization by using Exchange
ActiveSync.
User Issues
You discover the following user issues:
• Some users report that, intermittently, they fail to connect to their email from their
Windows Phone device.
• Some users from the New York office report that some searches from Outlook Web App
return incomplete results.
• Some of the users in each office report that they fail to access their mailbox during the
maintenance period of the Active Directory domain controllers.
You verify that all of the remote users can connect to the network successfully by using a VPN
connection, and can then launch Outlook successfully.
Partnerships
Contoso recently entered into a partnership with a company named A) Datum Corporation. A) Datum has a main office and four branch offices. The main office is located in Toronto.
A) Datum has a messaging infrastructure configured as shown in the following table.

Requirements
Planned Changes
Contoso plans to deploy a hardware load balancer in the New York office. The load balancer must
bridge all SSL connections to the Exchange servers.
You plan to deploy two new Exchange Server 2013 servers in a virtual server environment in the
Miami office. The servers will host a few mailboxes as part of an evaluation of resource utilization for
virtualized Exchange servers.
You also plan to deploy a high availability solution for Mailbox servers in the
You plan to replace the email appliance in New York because of recent power outages.
Business Requirements
Contoso identifies the following business requirements:
• Minimize the hardware costs required for a load balancing solution.
• Minimize the software costs required for a load balancing solution.
• Minimize user interruptions if a service fails on a Mailbox server.
• Minimize user interruptions if a service fails on a Client Access server.
###EndCaseStudy###

You need to identify which business requirement will be met by implementing the planned hardware
load balancer.
Which business requirement should you identify?
