Designing a Microsoft Exchange
Server 2003 Organization
Exam Questions, Answers, Braindumps (70-285)
Hi to all and thanks to www.exams.ws and www.4exam.com
But there’s no need to have it from both of
them, only questions from only one are sufficient
I think. Here is my contribution.
Case Study #1, Woodgrove Bank
Overview
Woodgrove Bank provides business banking and financial
services throughout the world.
The company is centrally administered from a main
office in New York City.
Physical Locations
The company has 20 branch offices throughout the world.
Each branch office belongs to one of six regions.
No region contains more than four branch offices.
Each branch office has 800 users.
The main office has 1,000 users.
Many users work from home after business hours.
They access e-mail by using a Web interface.
Planned Changes
The company currently uses an outsourced Web-based
messaging system.
They are implementing Exchange Server 2003.
Messages from the old messaging system will not be
migrated.
There is no existing internal messaging environment.
Directory Services
• The company has a single Active Directory
domain.
• Each branch office has a single domain controller,
which is configured as a global catalog server.
• Each office connects directly to the Internet.
The Internet connection in each office uses a perimeter
network.
• The internal firewall on the perimeter network
in each branch office is configured so that domain
member servers can be placed on the perimeter network.
Administration
• The IT staff at the main office will control
all new Exchange servers.
• However, each region also has a server technician
who must be able to modify the
Exchange configuration on the server that contains
mailboxes for that region.
Security
• All servers that provide services to Internet
users must be located in a perimeter network.
Other servers are not permitted in the perimeter networks.
• The company requires end-to-end encryption
when users access their e-mail by using the
Internet.
• All inbound e-mail must be scanned for viruses.
Interviews
Chief Executive Officer:
• I know that the antivirus software for the
Exchange system is purchased on a server-byserver
basis.
• I want to minimize the number of servers on
which we must install the software.
• We need to ensure that the failure of a single
Microsoft Outlook Web Access server does not prevent
our users from accessing their e-mail when they work
from home.
• We also need to ensure that the failure of
any server will only have a minimal impact on the
ability of users, in each branch office, to send and
receive e-mail while they are in the office.
Messaging Infrastructure.
• All user e-mail messages must be backed up
daily.
• If a failure occurs, as much data as possible
must be recovered.
• However, several mailboxes support customer
service operations.
• Messages sent to these mailboxes do not need
to be backed up and they do not need to be recovered
if a failure occurs.
• Users who work from home will access e-mail
by using their home Internet connections.
• They will connect to a Microsoft Outlook Web
Access server that is hosted at their local branch
office.
• All Outlook Web Access servers will be configured
to require SSL-encrypted connections.
E-Mail Clients
• Users will use Microsoft Outlook to access
e-mail in the new Exchange Server 2003 environment.
Case Study #1, Woodgrove Bank (6 Questions)
QUESTION 1
You need to design a storage strategy that meets all
business and technical requirements. What should you
do?
A. Create a storage group for each office. Within
each storage group, create a single database.
B. Create a storage group for each region. Within
each storage group, create a single database.
C. Create a storage group for each region. Within
each storage group, create separate databases for
each office in that region.
D. Create a single storage group. Within that storage
group, create a separate database for each office.
Answer: C
Explanation
Requirements
All user e-mail messages must be backed up daily,
so that in the event of a failure occurring, as much
data as possible is recovered.
The company has 20 branch offices throughout the world.
Each branch office belongs to one of six regions.
No region contains more than four branch offices.
Each branch office has 800 users and has a single
domain controller, which is configured as a global
catalog server. Each Exchange server can contain 4
storage groups, in which you can include 5 databases.
In total you can split your users into 20 databases,
which speeds up the recovery of any Exchange that
crashes, by using a new Exchange feature called Recovery
Storage Group.
They tell you that users will connect to a Microsoft
Outlook Web Access server and that this server will
be hosted at their local branch office.
They have one central office, 6 regions and each branch
contains no more than 4 offices. This means that you
require 7 Exchange servers 1 Server in the Central
site and 1 per region; 4 storage groups per server;
1 Database per group and 20 Data Bases 1 per office
in each region storage office.
Storage group configuration
An Exchange 2003 server supports up to four storage
groups. Each one has its own set of transaction log
files and supports up to five databases. How you configure
your storage groups affects Exchange performance,
including how long it takes to back up and restore
Exchange databases. To achieve better performance,
you should consider minimizing the total number of
databases on each server. You should also maximize
the total number of databases (five) per storage group,
before creating any additional storage groups. To
increase the time it takes to back up and restore
Exchange, consider limiting the size of each of your
Exchange databases so that you can recover each database
in a reasonable amount of time.
Storage Group Configuration
The Exchange store uses two types of databases: mailbox
stores and public folder stores. These stores are
organized into storage groups. All of the databases
in a storage group share a single set of transaction
log files, a single backup schedule and a single set
of logging and backup-related settings.

QUESTION 2
You need to design an administrative model that meets
all business and technical requirements. What should
you do?
A. Place the mailboxes for each region on a separate
server. Create an administrative group for each region.
Assign each regional technician Exchange Full Administrator
permission over that region's administrative groups.
Assign the main office IT staff Exchange Full Administrator
permission over each administrative group.
B. Place the mailboxes for each region on a separate
server. Create an administrative group for each region.
Assign each regional technician Exchange Full Administrator
permission over all administrative groups.
Assign the main office IT staff Exchange Full Administrator
permission over each administrative group.
C. Place the mailboxes from multiple regions on each
server. Create an administrative group for each server.
Assign each regional technician Exchange Full Administrator
permission over the administrative groups that contain
servers that hold mailboxes for that region. Assign
the main office IT staff Exchange Full Administrator
permission over each administrative group.
D. Place the mailboxes from multiple regions on each
server. Create a single administrative group for all
servers. Assign each regional technician and the main
office IT Staff Exchange Full Administrator permission
over the administrative group.
Answer: A.
Explanation
They tell you that the IT staff at the main office
will control all new Exchange servers. However, each
region also has a server technician who must be able
to modify the Exchange configuration on server that
contains mailboxes for that region although they tool
us that must be able to modify the configuration they
do not tell us if they need to be able to modify the
permissions When you assign a user or a group Exchange
Full Administrator permissions, the user or the group
can fully administer Exchange Server computer information
and modify permissions.
Administrators, who have Exchange Full Administrator
permission can install, upgrade, remove, and perform
disaster recovery on servers in that Administrative
Group.
Incorrect Answers
B. Too much permission for Regional Technician over
other Admin Groups is not a required question
C, D. These places multiple regions on each server,
this cannot achieve the requirements and require more
administrative effort

QUESTION 3
You need to design a strategy for managing the messages
that are sent to the customer service mailboxes. What
should you do?
A. Create a separate storage group and database to
contain the customer service mailboxes.
Enable circular logging for this storage group.
B. Create a separate storage group and database to
contain the customer service mailboxes.
Set the deleted item retention period for this database
to zero.
C. Place the customer service mailboxes on a new mailbox
store in the storage group that contains the main
office user mailboxes. Enable circular logging for
this storage group.
D. Place the customer service mailboxes on a new mailbox
store in the storage group that contains the branch
office user mailboxes. Set the deleted item retention
period for this database to zero.
Answer: A
Explanation
Since the requirement is: messages sent to the database
of "Customer Service", which does not need
to be backed up and recovered, letter A is the best
choice.
When circular logging is on, Exchange writes transaction
logs as usual; however, after the checkpoint (Edb.chk)
file has been advanced, the inactive portion of the
transaction log is discarded and overwritten.

Logs KB article 147524
QUESTION 4
You need to design the Exchange 2003 server configuration
for remote e-mail access. What should you do?
A. Configure the front-end servers in each branch
office to be members of a new Active Directory site.
B. Configure the back-end servers to have server encryption
certificates issued by a commercial certification
authority (CA).
C. Configure two back-end servers to be members of
a Network Load Balancing cluster.
Configure Network Load Balancing for inbound RPC connections.
D. Configure multiple front-end servers in each branch
office to be members of a Network Load Balancing cluster.
Configure Network Load Balancing for inbound HTTPS
connections.
Answer: D
Explanation
Based on information gathered from the CEO, we need
to ensure failure tolerance, which is provided by
configuring multiple front-end servers.
CIO is concerned about spending too much in antivirus
licenses but CIO requests an OWA system with fault
tolerance in the whole organization. The only way
to achieve this with the given answers; is with answer
D.
QUESTION 5
You need to design the deployment of antivirus software.
What should you do?
A. Install the antivirus software on each mailbox
storage server.
B. Install the antivirus software on each Outlook
Web Access server.
C. Install the antivirus software on one Outlook Web
Access server at each office.
D. Install the antivirus software on a back-end server
that contains no mailboxes.
Answer: A
Explanation
They do not offer an infrastructure using SMTP in
and out connector to access Exchange server If the
requirement of the CIO is to reduce the numbers of
servers that will have AV installed and also to protect
the external and internal system, the AV should be
installed in the Mailbox server.
Front end servers do not have mail enabled recipients.
