Overview
Fabrikam, Inc. is an international manufacturing company that has 5,000 employees. The company has sales,
marketing, research, and human resources departments.
Fabrikam has two main offices and three branch offices. The main offices are located in New York and London.
The branch offices are located in Seattle, Montreal, and Paris.
The offices connect to each other by using a WAN link. Each office connects directly to the Internet. The WAN
connections from the main offices to the branch offices are reliable.
Existing Environment
Exchange Environment
The Exchange Server organization contains servers that have either Exchange Server 2010 or Exchange
Server 2013 installed. Each main office contains two Exchange Server 2013 servers. Each branch office
contains one Exchange Server 2010 server.
MX records are configured to deliver email to the offices in New York and London. Email is delivered to the
London office only if the New York office is unavailable.
Each office is configured to use a separate namespace for client access. The New York office is configured to
use a namespace of mail.fabrikam.com.
The servers in the New York and London offices are members of a database availability group (DAG). Each
mailbox database in the New York and London offices has three copies.
The technical support staff in the branch offices have administrative access to the existing Exchange servers
and are assigned Organization Management permissions.
Users from the sales department frequently send email messages that contain the Social Security number of
customers in the United States.
Problem Statements
Fabrikam identifies the following issues on the network:
Users in the Paris office report that when launching Microsoft Outlook, they receive a security alert indicating
a certificate name mismatch. The security alert is not generated when they connect to Outlook Web Access.
Users from the other offices do not report receiving the security alert.
Network administrators report that the mailbox databases in the New York office sometimes activate on the
Exchange servers in the London office, resulting in poor performance for the New York office users.
Planned Changes
Fabrikam plans to implement the following changes to the network:
Upgrade the organization to Exchange Server 2016 during the next six months.
Enable online document viewing and editing from Outlook on the web.
High Availability Requirements
Fabrikam identifies the following high-availability requirements for the planned deployment:
Mailbox databases that contain mailboxes for the New York office users must only be activated on the
servers in the London office manually.
All client access connections to the London and New York offices must use load-balanced namespaces.
The load balancing mechanism must perform health checks.Security and compliance requirements
Fabrikam identifies the following security and compliance requirements:
After the planned upgrade, the maximum mailbox size must be 5 GB.
Administrators from the branch offices must be able to view the mailbox properties and reset the passwords
of the users, but must be prevented from changing the mailbox database configurations.
Users who are involved in legal disputes with customers must be prevented from permanently deleting email
messages pertaining to the dispute. The users must be able to delete all other messages permanently.
If a user enters a Social Security number in an email message addressed to an external recipient, the user
must receive a notification before sending the message. If the user sends the message, the message must
not be delivered. A compliance officer must be notified of the violation.
Connectivity requirements
Fabrikam identifies the following connectivity requirements:
Connections for inbound and outbound email must be initiated and terminated from an Edge Transport
server in the perimeter network.
All external client connections from the branch office users must be proxied from the New York office to the
branch offices.
The number of namespaces used for client access must be minimized.

###EndCaseStudy###

You deploy Layer 7 load balancers to the New York and London offices.
You are planning the namespace configuration that will be used once you complete the planned upgrade to
Exchange Server 2016.
You need to recommend a solution to meet the connectivity requirements for the namespaces.
What should you recommend?

A.
On the New York office servers, change the internal URLs to mail.fabrikam.com.

B.
On all of the branch office servers, change the external URLs to $null.

C.
On all of the branch office servers, change the external URLs to mail.fabrikam.com.

Explanation:
* Scenario:
/ Fabrikam connectivity requirements include: The number of namespaces used for client access must be
minimized.
/ Each office is configured to use a separate namespace for client access. The New York office is configured to
use a namespace of mail.fabrikam.com.
