Case Study: 2
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 recommend a temporary solution to reroute all of the outbound email messages
through the Miami mail appliance during the planned replacement of the New York mail appliance.
What are three possible ways to achieve the goal? (Each correct answer presents a complete
solution. Choose three.)
A.
Modify the value of the SmartHost of the Send connector in the New York office.
B.
Increase the cost of the Send connector in the Miami office.
C.
Increase the cost of the Send connector in the New York office.
D.
Decrease the cost of the Send connector in the New York office,
E.
Modify the value of the SmartHost of the Send connector in the Miami office.
F.
Disable the Send connector in the New York office.
Can anyone explain why you would disable the send connector in the new York office? Surely this would stop the users in new York from being able to send emails altogether? Or does this mean that we have to assume that we have already created a new send connector?
Joe – Since the question ask for three answers and B, D, and E do not make any sense you basically have to choose F. I realize that does not answer your question but considering the fact that they are asking you how to force mail out though Miami, i would am guessing that you have to assume the new connector is existing.
One thing I have learnt from doing Microsoft exams is that sometimes you have to just rule answers out until there are only the correct answers left.
After reading the question over and over I have realised these answers are probably correct.
At first I though A was an option, before I found the part about research.contoso.com mail going through the appliance at Miami.
My mistake, A is correct, I meant to say E
Think of it like this, if C makes sense then Exchange is aware of the Miami connector otherwise it wouldnt matter what the cost of the connector is.
In this same sense if you completely remove the NY send connector Exchange still knows that Miami has a connector with the address space of * and will use that regardless of the cost if it is the only connector available within the organization.
I am curious if anyone can tell me why E is not an answer and why F is not wrong just as Joe is asking?
A is correct, not E.
According to the case study:
All contoso.com email is going out in New York, all research.contoso.com mail is going out in Miami. Both are using a mail appliance for outbound email so they both have a smart host send connector configured. Assuming they’ve been setup with default settings, they both have a cost of 1. So you have to increase the cost of the send connector in NY to force the traffic to go out in Miami.
And why weren’t the other sites using the Miami send connector before the modification? Well, because all sites are linked directly to NY, so the cost to use the Miami send connector would have been higher.
Thank you Guy. Well put.
A – true. The servers will be directly sent to smarthost in Miami
C – true. The server selects the connector with the shortest path to the Internet and using intra-site connectors will be sent first to the servers in Miami -> Internet.
F – true. The NY servers send mail to Miami throuh AD intra-site connectors -> Internet
