QUESTION 2
How should you ensure that the Active Directory design will accommodate Exchange 2000
Server?

A. Define the single domain at a Microsoft Windows 2000 site.
Ensure there is a single global catalog Server in Chicago, which is used by all of the
regional offices.
B. Define the single domain at a Microsoft Windows 2000 site.
Configure one domain controller in each location as a global catalog Server.
C. Define each location as a Microsoft Windows 2000 site.
Configure the domain controller in Chicago as global catalog Server for all locations.

D. Define each location as a Microsoft Windows 2000 site.
Configure one domain controller in each location as a global catalog Server.
Answer: D
Explanation
They tell use that AD implementation will be one Domain one site in Proseware Corporation
They also rely heavily on email communication, they will like to recover mailbox user for
everyone in one single server, and they want to reduce the cost of administration in each regional
mail servers.
In this way we can achieve the entire goal by placing the entire server in the central site and just
and site for performance replication reason and organizational structure. Also to get a better
performance we place a GC in each site for Exchange search in Active Directory.

QUESTION 3
What should you do to improve employee's access e-mail by using Microsoft Internet
Explorer 5?

A. Install a front-end Server at each location.
Configure each Server to use SSL, and use Outlook Web Access to connect to these
servers.
B. Install two front-end servers in Chicago.
Configure each Server to use SSL, and use Outlook Web Access to connect to these
servers.
C. Install an IIS Server at each location
Configure each Server to use SSL, and use Outlook Web Access to connect to these
servers.
D. Install two IIS servers that use SSL in Chicago.
Install Outlook Web Access on each of these servers.
Answer: B
Explanation
They have this administrative model:
The administrator of the ProseWare Corporation domain is performed in the Chicago office. All
Exchange Server computers are administered from the Chicago office.
They want to reduce the administrator cost of supporting each of the Exchange Server computers
at the six regional offices.
They need to access mail from Internet explorer 5. In this way they need to access to a front end
servers based in their central location Chicago

QUESTION 4
How should you change the client computer software for the managing consultants to meet
the interoperability requirements?

A. Replace the POP3 and IMAP4 with Outlook Web Access.
B. Replace the POP3 and IMAP4 software with Outlook 2000.
C. Replace the IMAP4 software with POP3 software.





D. Replace the POP3 software with IMAP4 software.
Answer: A
Explanation
As result of redeploy we just need to kept one Bill of client, Internet Explorer provide access to
most of functionality also because is a better solution to provide access to migration consultants
from remote locations

QUESTION 5
How should you design the Active Directory Connector (ADC) Recipient Connection
Agreements?

A. Create a one-way Connection Agreement for one Exchange 5.5 site.
B. Create a one-way Connection Agreement for each Exchange 5.5 site.
C. Create a two-way Connection Agreement for one Exchange 5.5 site.
D. Create a two-way Connection Agreement for each Exchange 5.5 site.
Answer: B
Explanation
Active Directory Connector, provide synchronization between Exchange 5.5 and Exchange 2000
Active directory object, in Exchange 5.5 each site have each own directory and LDAP provider,
in this way we need to establish one connection agreement for each Exchange 5.5 site

QUESTION 6
Which upgrade method should you use to upgrade ProseWare Corporation's mailbox
servers to Exchange 2000 Server?

A. Use the Exchange 2000 Server exmerge utility to move the mailboxes to Exchange
2000 Server.
B. Use the move mailbox upgrade method to a new Exchange 2000 environment.
C. Use the in place upgrade feature in Exchange 2000 Server.
D. Use the leapfrog upgrade method using the two new servers.
Answer: C
Explanation
Because they just have a domain which several sites one of upgrade methods is the in pace
upgrade, after taken all the necessary precautions, backup architecture, replication, connector,
routing and so on is the fast way to do it.
Also they tell us that all Exchange 5.5 are capable to run Exchange 2000, that is one of the reason
for do take the in place upgrade approach.

QUESTION 7
The Active Directory Connector (ADC) in the labs is not updating the directory properly.
What should you change to solve this problem?


A. Reinstall the Exchange 2000 Server ADC. Reconfigure the connection agreement to
the one way.
B. Configure the Exchange Server 5.5 and the ADC connection agreement to use LDAP
port 389.
C. Configure the Exchange Server 5.5 and the ADC connection agreement to use LDAP
port 390.
D. Reinstall the Windows 2000 ADC. Reconfigure the connection agreement to be oneway.
Answer: C
Explanation
Windows 2000 uses its own LDAP Server service which initializes prior to Exchange Server's
LDAP Server service. This service uses Ports 389 and 636. When Exchange Server starts, the
Exchange Directory attempts to initialize the same ports (for Secure Sockets Layer connectivity).
The above stop errors are generated for this initialization failure

Use a routing group for each existing Exchange Server 5.5 site.
D. Use an administrative group for each Exchange Server 5.5 site.
Combine all Exchange Server 5.5 sites into one routing group.
Answer: C
Explanation
The meaning of administrative group in exchange 2000 change a bit from those concepts that you
may have about exchange 5.5
In exchange 2000 an administrative group is used by grouping the differences servers that will
configure a routing group and from each routing group we design the flow between connectors

database?

A. Back up each Exchange database separately.
B. Back up each Exchange storage group separately.
C. Back up the Exchange 2000 Server computer offline.
D. Back up drive M on each Exchange 2000 Server computer.
Answer: B
Explanation
By doing different storage groups we can get a faster restore back, because usually in a good
design each storage group will be placed in different disk array
Reference
Chapter 12 -Server Design for Backup and Restore

QUESTION 10
How should you configure the Exchange 2000 Server mailbox computers in Chicago to meet
archiving requirements?

A. On one Server, create one storage group with one database. Place the executive's
mailboxes and 800 other mailboxes in this database. On the second Server, create one
storage group with one database. Place 1000 mailboxes in this database. Backup each
storage group to tape.
B. On one Server, create one storage group with one database. Place the executive's
mailboxes and 800 other mailboxes in this database. On the second Server, create one
storage group with one database. Place 1000 mailboxes in this database. Backup each
database to tape.
C. On each Server create one storage group with five databases. Place the executive
mailboxes in one database. Place 200 mailboxes in each of the remaining databases.
Back up the storage group to tape.
D. On each Server create one storage group with five databases. Place the executive
mailboxes in one database. Place 200 mailboxes in each of the remaining databases.
Back up each database to tape.
Answer: C
Explanation
The recommendation for database capacity planning on non-clustered Exchange 2000 Servers is a
maximum of four storage groups that contain a maximum of five databases for each storage
group. This results in a maximum of 20 databases for each Exchange 2000 server.
They have 2000 people in Chicago, we create a one storage group 5 databases in total, we can put
the executives in one database and split the rest in the other databases
Incorrect answers:
You can not put five databases in one storage group. This limit is enforced inside the Exchange
System Manger snap-in, so administrators cannot create more storage groups than the system
enables.

Bismarck. The company has hundreds of offices and research factories, which are located all over
the world. The company employs approximately 10,000 computers.
A large company named Enchantment Lakes Corporation owns Contoso, Ltd. The headquarters
Enchantment Lakes Corporation is located in New York. Contoso, Ltd., exercises complete
control of over its own business.
Contoso, Ltd., recently acquired a small agricultural research company that has offices in
Calcutta, Milan and Tripoli.

Company Profile:

Contoso, Ltd., specializes in crop development, generic manipulation and the sale of seeds. The
company's primary customers are farmers and government agencies. The company has
approximately 10,000 Exchange Server mailboxes.
Bismarck headquarters employs approximately 5,000 people. Each of the other regional offices
in the following cities employs 750 and 1,000 people.
.
Bonn

.
Cairo
.
Hong Kong
.
Rio de Janeiro
The other company locations each employ between 5 and 100 people.
Network planning is preferred in Bismarck. Each regional office has an IT staff that is
responsible for the day-to-day operations of the servers and network connections in that office.
Factors that influence Business Strategies:

Communication and collaboration are very important at Contoso, Ltd., The company believes that
it will succeed if it can successfully communicate its message to employees, to customers and to
shareholders.
Contoso, Ltd., will continue to operate as an independent company. However, employees of
Contoso, Ltd., will continue to communicate much more frequently with Enchantment Lakes
Corporation in the future.

Existing IT Environment:
Directory Design:

The Contoso, Ltd., Active Directory design is shown in the Exhibit.








Contoso, Ltd., keeps the Active Directory employee data, such as office location, department and
phone number, up-to-date by exporting information from the Human Resources (HR) employs
database to the Exchange Server 5.5 directory.
The connection from the HR database to the Exchange Server 5.5 is written in Directory API
(DAPI), and work is currently being done to migrate the connection to Active Directory Services.
Contoso, Ltd., keeps the Active Directory employee data, such as office location, department and
phone number up-to-date by exporting information from the Human Resources (HR) employee
database to the Exchange Server 5.5 directory.







The connection from the Human Resources (HR) database to Exchange Server 5.5is written in
Directory API (DAPI), and work is currently being done to migrate the connection to Active
Directory Services Interface (ADSI).
The migration will not be completed until the Exchange 2000 Server deployment is complete.


Messaging Environment:

Bismarck headquarters has two mailbox servers. BismarckMail1 and BismarckMail2.
Headquarters also has bridgehead mail Server named BismarckHUB1.
Every Contoso, Ltd., location has at least one Exchange Server 5.5 computer.
Exchange Server 5.5 is configured as one Exchange organization and 12 Exchange sites. Sites
that have stable bandwidth are connected to Bismarck headquarters by means of site connectors.
Sites that have unreliable connections to headquarters use X400 connectors.
When Exchange Server 5.5 was installed, sites were configured according to number of users and
the types use Microsoft Outlook 2000.
SMTP mail is used at all Contoso, Ltd., offices to communicate to Enchantment Lakes
Corporation. However, full SMTP e-mail addresses are currently typed manually.
All of the Exchange Server computers in Contoso, Ltd., locations are members are member
servers. The Contoso, Ltd., WAN is currently configured in a hub-and-spoke topology.
Public folder usage at Contoso, Ltd., is minimal. The public information store is 200 MB. Public
folders are not currently backed up.
The Calcutta, Milan and Tripoli offices of the newly acquired agriculture-research company do
not have e-mail servers.


.
Users in Calcutta offices use the mail Server in the Hong Kong office and store the e-mail
messages on the Server.
.
Users in the Milan office use the mail Server in the Bonn office and download the e-mail
messages from that Server.
.
Users in the Tripoli office use the mail Server in Cairo office and store these e-mail
messages on that Server.
Network Infrastructure:

The Contoso, Ltd., WAN design is shown in the exhibit.
Contoso, Ltd., plans to upgrade the WAN. However, the company will be unable to upgrade for
at least two years.
The regional offices run Microsoft Windows 2000 Advanced Server. Offices that have lower than
500 employees run Windows 2000 Standard.







All Internet access is routed through Bismarck headquarters.
There are domain controllers at each regional office. Most of other locations use one Server for
all services.
All domains are administered locally, except for the North American domains and servers. The
North American domains are administered from Bismarck headquarters.


Exchange 2000 Server Requirements and Goals:
Security Requirements:

Contoso, Ltd., and Enchantment Lakes Corporation plan to use e-mail to communicate more
frequently after Exchange 2000 Server is implemented.
The companies want messages between executives to be encrypted in the future; they might want
the ability to encrypt all messages that are sent between the two companies.


Archiving Requirements:

Contoso, Ltd., wants to backup the mailboxes and public folders every night and to create weekly
and monthly archives.
Contoso, Ltd., does not currently have a recovery solution. Toe expedite the recover of e-mail
company wants to install recovery servers at strategic locations.


Availability Requirements:

Contoso, Ltd., wants to cluster the servers in the regional offices and headquarters because there
are more people working at those offices and because the company wants to provide high
availability for mailbox access.
Contoso, Ltd., wants to implement Outlook Web Access to make the company's mail Server more
accessible to employees. The Sales team in particular must have this improved accessibility.
Users must be able to connect to local e-mail servers even when WAN connections are down.


Interoperability Requirements:

Contoso, Ltd., wants SMTP e-mail addresses for Enchantment Lakes Corporation to appear in an
address list.

Goals:

Bismarck headquarters has two computers that the company plans to use as dedicated instant
Messaging servers. The servers will be named M1 and M2.
The company is considering the implementation of additional front-end servers in the five
regional offices: Bismarck, Bonn, Cairo, Hong Kong and Rio de Janeiro.
Users in Milan office must be able to view their own calendars and some public folders. They
must be able to access their e-mail when they are offline.
Contoso, Ltd., plans to use public folders as a central repository for all research documents.
The company wants to implement a backup solution for public folders. In addition, the company
wants to be able to restore all public folders in the most efficient manner.
The company wants to continue storing confidential research information in same public folders
and allowing employees of only the research facilities to have access to this data.
The administrative staff at Bismarck headquarters wants to limit the administrative overhead
necessary for maintaining message routing throughout Contoso, Ltd.,


Client Computer Configuration:

Contoso, Ltd., wants to implement instant Messaging between the Bismarck headquarters and
Contoso, Ltd., and the New York headquarters of Enchantment Lakes Corporation. The first
implementation of instant Messaging will be an experimental test phase.
The Sales team frequently hosts meetings in Canberra and Athens. The Sales will require the use
of Outlook Web Access, when they are not in their home office.






Contoso, Ltd., wants to acquire additional small agricultural-research firms and quickly integrate
them into the company. Typically the e-mail communication between the companies will occur
by means of SMTP or X400 mail systems.

QUESTION 2
What should you do to enable communication between Contoso, Ltd., and newly acquired
research facilities until the facilities are fully integrated into the organization?

A. Implement an X 400 connector or an SMTP connector on the front-end mail Server at
Bismarck headquarters.
B. Implement an X 400 connector or an SMTP connector on the back-end mail Server at
Bismarck headquarters.
C. Implement an X 400 connector, or use the current SMTP connector that is on one of
the SMTP connector servers.
D. Implement a dedicated Server for foreign connectors at the regional office that is
nearest to the office that needs to communicate with the new research facility.
Answer: D

Explanation
They tell us
Typically the e-mail communication between the companies will occur by means of SMTP or
X400 mail systems.
Also they tell us Sites that have unreliable connections to headquarters use X400 connectors.
They have Exchange 5.5 servers, they have very poor lines between the central sites and some of
theirs spoke X.400 protocol have a better performance for routing large e-mail than smtp, also we
van design a X.400 flow queuing messaging system to transmit this email out of normal business
hours

X.400 Connector An Exchange component integrated with the MTA that can be configured to
connect sites within Exchange, or to route messages to foreign X.400 systems.
X.400 Recommendations Defines the standard interfaces of an electronic messaging system.
These recommendations specify the structure of a message handling system, message structure
and components, and the method used to transfer messages.
X.400 transport stack Networking software required to support X.400 server-to-server message
transport.
QUESTION 3
What should you do to add to Contoso, Ltd's DNS Server SRV records to accommodate
unified namespace for instant Messaging?

_rvp_tcp.contoso.com SRV 10.0.80 BismarckReg1.contoso.com
Answer: A
Explanation
They tell us
Bismarck headquarters has two computers that the company plans to use as dedicated instant
Messaging servers. The servers will be named M1 and M2.
The Contoso.com has register Contoso.com namespace already
In this case the SRV DNS records in Contoso.com name space will be
_rvp_tcp.contoso.com SRV 0.0.80 M1.contoso.com for server M1
rvp_tcp.contoso.com SRV 10.0.80 M2.contoso.com for server M2
Configuring Instant Messaging

Exchange Server 5.5 directory.
Answer: B
Explanation
They tell use
Users in Milan office must be able to view their own calendars and some public folders. They
must be able to access their e-mail when they are offline.
Contoso, Ltd., wants SMTP e-mail addresses for Enchantment Lakes Corporation to appear in an
address list.
One of the ADC Active Directory Connector is to schedule the replication flow, between
Exchange 5.5 LDAP directory and the Active directory, GAL and users objects.
The way to take their infrastructure as much updated as is possible we will select the option to
replicate continuously. In that way any user that still in Exchange 5.5 or Exchange 2000, can
located each other on the GAL (Global Address List) Book

QUESTION 6
How should you modify the Active Directory Design to provide increased availability of
directory access for Exchange server?

A. Ensure that there is a global catalog server at each location that has at least one
Exchange server computer.
B. Ensure that there is a DNS server at each location that has at least one Exchange
server computer.
C. Ensure that there is a domain controller at each location that has at least one Exchange
server computer.






D. Ensure that there is a DHCP server at each location that has at least one Exchange
server computer.
Answer: A
Explanation
To provide to Exchange 2000 with a rapid way to search any user mail enabled the best way for
that is to locate Exchange 2000 and an AD GC in the same subnet.
The reason is that when you are mailing to a user mail enabled Exchange need to lookup in the
MS-exchange attributes like GAL.
Exchange make a 3268 LDAP port query to a GC to located any mail enabled resource

Case Study #2, Hiabuv Toys

Introduction:

You are hired by Hiabuv Toys to assist the company with migrating its messaging system from
Exchange Server 5.5 to Exchange 2000 Server. You need to evaluate the company's current
messaging infrastructure, access current and future business needs, and design and deploy
Exchange 2000 Server in the company's environment.

Background:
Company Profile:

Hiabuv Toys designs and sells high-quality electronic toys. The company sells its products
through its web site, catalog distributors and rental stores. The company has 8,000 employees in
five U.S locations.
Company headquarters are located in Portland. Office locations and number of employees are
shown in the list.

Location Employees

Chicago 2,000
Dallas 600







Kansas City 1,500
Los Angeles 800
Portland 3,000

Business Plan:

Hiabuv Toys currently develops new toys. The company actively seeks customer feedback on
how to improve its products.

Existing IT Environment:
Network Infrastructure:

The network diagram is shown in exhibit.


Chief Information Officer (CIO):

I want to implement Exchange 2000 Server so that we can create collaboration services that will
allow our employees to communicate online with our business partners and suppliers in real time.
We are planning to give all of our employees Handheld PCs. We want to ensure that employees
can access their e-mail while they are in the office or in remote locations.

Director of IT:

Our environment consists of a Microsoft Windows 2000 Active Directory network. We run
Windows 2000 professional on all of our client computers.
We have an Exchange Server 5.5 messaging system for the entire company. We have a separate
Exchange site for each office, with at least one Exchange Server computers in each office.
I want to ensure that our high-speed data lines are not burdened with unnecessary network and
messaging traffic, even if we must spend more time managing our messaging infrastructure. I
want the messaging systems to use as little bandwidth as possible over our WAN connections.

E-mail manager:

All administration for the Exchange Server 5.5 computers is performed by an IT group in the
Portland office Network administration for the LANs and the WAN is performed by a separate
technical support group.
Each office has a LAN analyst who is responsible for resetting user passwords, managing
distribution lists and Updating exchange user information, such as telephone numbers and
addresses.
The deployment plan details the following deployment order:

1. Portland
2. Dallas
3. Los Angeles
4. Chicago

5. Kansas City
The company executives and designers are in the Portland office. Executives should have their
mailboxes backed up daily, and the backup tapes should be retained for atleast one year. I also
want to ensure that we can recover their mailboxes as quickly as possible and before those of
other network users, if possible.
Designers should have their mailboxes backed up daily, and the backup tapes should be
maintained for five years. We should be able to restore their mailboxes after those of the
executives, but before those of all other network users.
We have an aggressive internship program that places a total of 20 to 30 interns in various
departments throughout the company. I want to limit the size of each interns mailbox to 20MB.
I want to allow employees to access their e-mail by using home computers, but I do not want our
technical support staff to provide equipment or install special software on these home computers.
Because the migration might take the several months, I want to ensure that out IT group can
continue to use the Exchange 5.5 Administrator application until all offices are upgraded to
Exchange 2000 Server.
I want to use the Exchange Server 5.5 computer in Portland office as the bridgehead Server for
the Active Directory Connector (ADC) because it has a faster CPU and more disk space than the
other Exchange Server 5.5 computers.
Messaging System:

Each office currently has its own Exchange Server 5.5 computer in the Portland and Chicago
offices.
Exchange Server computer has approximately 30GB of data in the private information store and
approximately 8GB of data in its public information store. Nightly backups of Exchange Server
computers in the Portland and Chicago offices currently take 10hours each.
The total data stored on each of the Exchange Server 5.5 computer in the other company offices
is between 5Gba and 10 GB.
All Exchange 2000 Server configurations should allow maximum single-instance storage and
should minimize Server memory usage where possible.
Employees use Microsoft Outlook 2000 for e-mail use.


Hardware:

These benchmarks were achieved when Exchange 2000 Server was tested on the planned
hardware configurations.

.
Each Exchange 2000 Server computer can support 3,000 users.
.
Each Exchange 2000 Server computer can generate approximately 45 global catalog queries
per second.
.
The global catalog Server configuration can support 240 queries per second.
Questions, Case Study #2, Hiabuv Toys

QUESTION 1
How should you configure the Active Directory Connector (ADC)?


A. Configure a one-way connection agreement from Active Directory to each Exchange
Server 5.5 site.
B. Configure a one-way connection agreement from Exchange Server 5.5 site to Active
Directory.





C. Configure a two-way connection agreement between Exchange Server 5.5 site and
Active Directory.
D. Configure a two-way connection agreement between the hub Exchange Server 5.5 site
and the root domain in the Active Directory forest.
Answer: A
Explanation
They tell us
I want to ensure that our high-speed data lines are not burdened with unnecessary network and
messaging traffic, even if we must spend more time managing our messaging infrastructure. I
want the messaging systems to use as little bandwidth as possible over our WAN connections.
To avoid part of the sync traffic we just select one way replication model.
Also because they have several site we need to deploy different connections agreements from
each Exchange site.

QUESTION 2
What should you do to minimize the effect of denial of service attacks on the Server that is
used by company employees for remote e-mail access?

A. Use two storage groups on the Exchange 2000 Server computer that provides Internet
mail access.
B. Place two front-end Exchange 2000 Server computers in a perimeter network. (DMZ).
C. Enable IPSec on the Exchange 2000 Server computer that provides Internet mail
access.
D. Enable SSL connections on the Exchange 2000 Server computer that provides Internet
mail access.
Answer: B
Explanation
They tell us
I want to allow employees to access their e-mail by using home computers, but I do not want our
technical support staff to provide equipment or install special software on these home computers.
In this way the best solution is to implement OWA access over SSL
Performance and Scalability
OWA performance and scalability benefit greatly from the partitioned services architecture of
Exchange 2000. The Exchange 2000 FE/BE server topology can be scaled horizontally by adding
front-end OWA servers as needed to increase application performance or client-load capacity.
Freed from the responsibility of managing a messaging database, a front-end OWA server
performs HTTP protocol handling and proxy functions at high speed.
OWA availability can also be increased by balancing client requests across multiple front-end
servers with Network Load Balancing (NLB). NLB ensures that user requests are directed to
servers that are available and helps maintain user Secure Sockets Layer (SSL) sessions (when
used) on a particular server until they disconnect.

QUESTION 3
Which permission should you designate to the Exchange administrators in the Portland
office?

A. Exchange Administrator
B. Exchange Full Administrator
C. Exchange View Only Administrator
D. Enterprise Administrator
Answer: B
Explanation:
They tell us
E-mail manager:
All administration for the Exchange Server 5.5 computers is performed by an IT group in the
Portland office Network administration for the LANs and the WAN is performed by a separate
technical support group.
The company executives and designers are in the Portland office. Executives should have their
mailboxes backed up daily, and the backup tapes should be retained for atleast one year. I also
want to ensure that we can recover their mailboxes as quickly as possible and before those of
other network users, if possible.
Exchange Administration Delegation Wizard
Similar to Active Directory Delegation of Control Wizard, the Exchange Administration
Delegation Wizard is a tool that assists in delegating responsibility for managing Exchange
configuration objects in Active Directory. As described in Table 11.3, the tool allows you to
assign one of three roles to groups or individual users. These roles are similar to the roles
assigned in Exchange 5.5. Use the wizard to modify the organization or the individual
administrative groups. Permissions are inherited from the top down, but can be overridden at
lower levels if desired.
Table 11.3 Administration Delegation Wizard roles

Role Right

Exchange View Only Administrator View configuration of all Exchange objects.
Exchange Administrator Modify configuration of all Exchange objects.
Exchange Full Administrator Same as Exchange Administrator with the added ability
to modify permissions on Exchange objects.
Create groups for the purpose of delegating administration by using Exchange Administration
Delegation Wizard instead of specifying individual accounts. This makes it easy to change
administrative rights by changing group membership rather than having to run the wizard again.

QUESTION 4
How should you implement a fault-tolerant configuration for users who access e-mail by
using Outlook 2000?






A. Use two front-end servers in each office.
B. Use clustered Exchange 2000 mailbox Servers.
C. Use an Exchange 2000 directory Server in Portland office.
D. Use an Exchange 2000 public-store Server in the Chicago office.
Answer: B
Explanation
In the Exchange architecture front end server must not have storage group for security reason, if
we would like to provide fault tolerance we must enable two or more NLB enable front end
server and on or more cluster server as back end server.
Windows Clustering
A server cluster is a group of independent computer systems, known as nodes, working together
as a single system to ensure that mission-critical applications and resources remain available to
clients. Each node has one or more physical disks used for storing the operating system, the swap
file, non-shared applications (such as Exchange 2000 binary files), and so on that only they have
access to. At the same time, every node is attached to one or more shared cluster storage devices
(such as a Storage Area Network) that contain the cluster quorum drive and Exchange 2000
shared resources (such as log files, public stores and message stores). Clustering allows users and
administrators to access and manage the nodes as a single system rather than as separate
computers.

QUESTION 5
You are designing a collaboration service that will fulfill the company's business
requirements. How should you ensure that the service could be used by internal users and
with suppliers?

A. Use an Exchange 2000 Server computer running the Chat service in auditorium mode.
Create a Web site that suppliers can access.
B. Use a dedicated Exchange 2000 client Server running the Chat service in moderated
mode. Create a Web site that suppliers can access.
C. Use a dedicated exchange 2000 Instant Messaging Server.
Allow internal employees to use Instant Messaging.
Enable suppliers to access the Hiabuv Toys instant Messaging Server.
D. On an exchange 2000 Server computer, create a public folder for each supplier.
Create an SMTP connector that will be used to replicate the contents of these public
folders to the suppliers.
Answer: C
Explanation
Chief Information Officer (CIO):
I want to implement Exchange 2000 Server so that we can create collaboration services that will
allow our employees to communicate online with our business partners and suppliers in real time.
We are planning to give all of our employees Handheld PCs. We want to ensure that employees
can access their e-mail while they are in the office or in remote locations.
In this way we need to plan an enable instant messaging and to enable to partners also to use it

QUESTION 6
How should you provide a redundant front-end Server configuration to support users who
access their e-mail from home?

A. Install two Windows 2000 Server computers that run Routing and Remote Access.
Connect modems to each of these servers.
B. Use two storage groups on each Exchange 2000 Server computer.
Use one storage group to support users who access e-mail from home, and the other
storage groups to support users who access e-mail in the office.
C. Place two front-end protocol servers on the Internet.
Configure these two servers to use Network Local Balancing (NLB).
D. Place the LDAP on the Internet.
E. Configure the LDAP server to have two separate ports: one for each protocol Server.
Answer: C
Explanation
Front end servers configuration in exchange is provided by configuring from two to 32 member
in a NLB cluster array to perform high availability and performance
HTTP-Specific Configuration
The front-end server's virtual directories and HTTP virtual servers must exactly match those of
the back-end server. In a default setting, no additional configuration is necessary on the front-end
server-the "exchange" and "public" virtual directories already match.
Optimizing the Front-End Server
You now have a default configuration front-end server that does not store any mailboxes. You
can optimize this server for OWA by removing unnecessary protocols.
The front-end server you are configuring will only be used for OWA (HTTP) services. Therefore,
the services required by the other e-mail protocols (POP3 and IMAP4) can be disabled. The
following table shows the Exchange services required for these protocols that you should disable.

Protocol Service Name to Internal Name
disable
POP3 Exchange POP3 POP3Svc
Exchange Information Store

Service MSExchangeIS
Exchange System MSExchangeSA
Attendant

IMAP4 Exchange IMAP4 IMAP4Svc
Exchange Information Store MSExchangeIS
Service
Exchange System Attendant

To stop and disable the services related to POP3 and IMAP4, use the Services Microsoft
Management Console (MMC) snap-in and configure the services to disabled.







Configuring a Back-End Server
Back-end servers must be specially configured to support the front-end server. First, the back-end
servers must be in the same domain as the front-end.
Public folders can be replicated in any way that is desired. Back-end servers can be accessed
directly if required, with no effect on the behavior of the front-end/back-end setup.
Reference
Exchange 2000 Upgrade Series
Chapter 8 -Installing Front-End Servers

QUESTION 7
What should you do to maximize security on the Server that is used by company employees
for remote e-mail access?

A. Use the Internet Authentication Service.
B. Use digital certificates on the client computers.
C. Place the front-end Server outside the Internet firewall.
D. Require SSL connections on the front-end Server.
E. Use IPSec to encrypt traffic on port 25.
Answer: D
Explanation
The best way to secure remote access to a OWA server is to enable SSL communications for
HTTP protocol
Security Requirements
Internet-connected OWA solutions require increased security measures and the application of
corporate security policies. Servers need to be exposed to the Internet, which usually involves
placing the front-end server behind a firewall.
Protecting user login and session data requires the use of SSL between the OWA client and the
Exchange server (front-end server only in an FE/BE server topology). To deploy this you must
plan for the acquisition and installation of Web server certificates, which are required to enable
SSL sessions.
If you plan to use an FE/BE server topology, only Basic Authentication is supported. Because
Basic Authentication does not protect user passwords, it is recommended that you use SSL,
particularly because SSL encrypted sessions are required by OWA when users change their
password.
If the OWA user community is limited to a corporate intranet, NTLM or Kerberos V5
authentication can be used to protect the logon process, but the user data sessions will remain
unencrypted. If you have a need to protect the data session in this environment, you should
implement Internet Protocol (IP) Security (IPSec) or SSL.

Case Study #3, ProseWare Corporation

Introduction:

ProseWare Corporation has hired you to provide design and deployment services for the
implementation of Microsoft Exchange 2000 Server throughout the company. This
implementation will be in upgrade from Exchange Server 5.5, which is the company's existing email
system.

Background:
Company Profile:

ProseWare Corporation supplies other companies with human resources for a variety of positions.
The company currently has offices in seven cities in the United States. Approximately 1,000
people work in each of six regional offices. Approximately 2,000 people work at the company
headquarters in Chicago. Two hundred of the headquarters employees are executives.

History:

ProseWare Corporation has expanded by acquiring other staffing resource companies. ProseWare
Corporation recently acquired a company in Boston. The Boston office employs about 800 people
who use Lotus notes for e-mail.

Business Plan:

The executives at ProseWare Corporation will continue the company's expansion by acquiring
other companies.

Existing IT Environment:
Directory Design:

ProseWare Corporation has a single Microsoft Windows NT 4.0 domain. The domain contains all
ProseWare Corporation user accounts and computers.
ProseWare Corporation is in the process of upgrading to Windows 2000. The company has
recently completed the Active Directory design and has implemented this design across the
organization. Only 50 employees have been added to Active Directory. The Active Directory
structure consists of one domain and one site. There are two domain controllers in each location.

Administrative Model:

The administrator of the ProseWare Corporation domain is performed in the Chicago office. All
Exchange Server computers are administered from the Chicago office.

Network Infrastructure:

ProseWare Corporation has a 100-Mbps LAN for servers at each location. Client computers of
each location are connected in a 10-Mbps LAN. ProseWare Corporation currently uses permanent
15-Mbps links to connect the locations. The network diagram is shown in the Exhibit.








ProseWare Corporation currently uses WINS for name resolution. There are two WINS servers at
each location. After the implementation of Windows 2000, the company will use DNS for name
resolution.

Servers:

All of the Exchange Server 5.5 computers are capable of running Exchange 2000 Server. The
existing Exchange Server configurations are shown in the exhibit.


The IT staff at ProseWare Corporation has installed Exchange 2000 Server on a domain
controller in a lab. They cannot connect to the Exchange 5.5 directory, which is also in the lab,
when configuring connection agreements.
There is money in the project budget for two additional Server computers.


Client Computers:

ProseWare Corporation has recently upgraded all client computers to Windows 2000







Professional. Most of these computers run Microsoft Outlook 2000. About 200 migrating
consultants use either POP3 or IMAP4 client computer software to remotely access Exchange.
Exchange Server 5.5 Outlook Web Access is available to all employees.

Messaging Environment:

ProseWare Corporation relies heavily on e-mail for communication within each location.
Approximately 5% of the company's e-mail messages are sent between locations.
The executives of the ProseWare Corporation use e-mail predominately to communicate with
other executives within the company. The executives store many more messages than the typical
ProseWare Corporation e-mail users.
When the company installed Exchange Server 5.5, the manager in charge of the e-mail system
instructed employees to use public folders.
However, she has discovered that employees are not using public folders.
Employees avoid using public folders because it's difficult to locate specific documents within
the public folders. Also, the folders are available only to people who use Microsoft Outlook.
The manager in charge of the e-mail system is concerned that if the employees did start to use
public folders. The resulting increase in usage might cause a bottleneck on the Exchange Server
computers and increased network traffic.
There is an internal SMTP host that relays across the existing Exchange 5.5 Internet Mail Service.


Exchange 2000 Server Requirements and Goals:
Security Requirements:

ProseWare Corporation wants to increase security to eliminate relay on undedicated commercial
e-mail, to prevent forged e-mail messages, and to reduce e-mail virus attacks.

Archiving Requirements:

The Exchange 2000 Server computers should be designated to allow recovery of mailboxes
without designating e-mail availability for every employee on any single Server.
All Exchange Servers must be recoverable to the point of failure.
All exchange backups should truncate and purge the log files.


Interoperability Requirements:

ProseWare Corporation wants to complete the upgrade from Exchange Server 5.5 to Exchange
2000 Server within one year.
The people in Boston who use the Nodes Server computer must have maximum interoperability
between Nodes and Exchange users at ProseWare Corporation.
An Exchange 2000 Server computer will replace the Nodes Server near the end of the Exchange
2000 implementation.
The manager in charge of the e-mail system wants to allow employees to access e-mail messages
by using Microsoft Internet Explorer 5 when they are not in the office. She wants this solution be
scalable and easy to use.
The Managing Consultants need to be able to their calendars and contacts with messaging client
software.

Support Requirements:

ProseWare Corporation wants to reduce the administrator cost of supporting each of the
Exchange Server computers at the six regional offices.
The company also wants to provide a single tool for the administration of Exchange Server 5.5
mailboxes and Exchange 2000 Server mailboxes.
The executives should have higher storage limits than the rest of the Exchange users. Every effort
to minimize the amount of storage used by the executives should be made.







Downtime should be minimized in the event of a failed upgrade.
