Requirements
Business Goals
Fabrikam has the following business goals:
• Minimize hardware costs.
• Minimize administrative
Minimize WAN link utilization between the two offices.
Planned Changes
Fabrikam plans to migrate to Exchange Server 2010 Service Pack 1 (SP1).
You plan to deploy a Hub Transport server named SEA-HUB-1 in the Seattle site.
You plan to deploy a Hub Transport server named LA-HUB-1 in the Los Angeles site.
Archiving Requirements
Email messages that are older than 180 days must be moved automatically to a distinct
mailbox database.
Security Requirements
Fabrikam must meet the following security requirements:
• Anti-spam filtering must be performed on all email messages before the messages enter the
network.
• The help desk staff must be prevented from modifying user accounts for users located in
remote offices.
• The number of permissions assigned to the members of a group named Exchange Server
Troubleshooters must be minimized.
Security Requirements
Fabrikam must meet the following security requirements:
• Anti-spam filtering must be performed on all email messages before the messages enter the
network.
• The help desk staff must be prevented from modifying user accounts for users located in
remote offices.
• The number of permissions assigned to the members of a group named Exchange Server
Troubleshooters must be minimized.
Redundancy Requirements
Fabrikam must meet the following redundancy requirements:
• A copy of all the mailbox databases must exist in both sites.
• The impact on users must be minimized if a single server fails.
• Users must be able to send and receive messages if a single server fails.

Problem Statements

The WAN link between the Seattle office and the Los Angeles office is heavily congested.
During normal business hours, the average round-trip time for packets to travel across the
WAN link is 200 ms. The portable computer of the manager of the accounting department
recently experienced a hard disk failure. The hard disk failure resulted in the loss of more
than two years of email and other personal data.

You are evaluating the implementation of SEA-HUB1 and LA-HUB1. You need to recommend a Hub
Transport server topology that meets the redundancy requirements of Fabrikam. The solution must
also support the business goals of Fabrikam. What should you include in the recommendation?

A.
Deploy SEA-HUB1 and an additional Hub Transport server named SEA-HUB2 to the Seattle site.
Deploy LA-HUB1 and an additional Hub Transport server named LA-HUB2 to the Los Angeles site.
Deploy a hardware load balancer to each site. Configure the virtual IP address of the load balancer to
point to the Hub Transport servers.

B.
Deploy SEA-HUB1 to the Seattle site. Deploy LA-HUB1 to the Los Angeles site. Create one Send
connector in each site.

C.
Deploy SEA-HUB1 to the Seattle site. Deploy LA-HUB1 to the Los Angeles site. Deploy a hardware
load balancer to each site. Configure the virtual IP address of the load balancer to point to the Hub
Transport servers.

D.
Deploy SEA-HUB1 and an additional Hub Transport server named SEA-HUB2 to the Seattle site.
Deploy LA-HUB1 and an additional Hub Transport server named LA-HUB2 to the Los Angeles site.
Create one Send connector in each site.
