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. If a failure occurs, as much 
data as possible must be recovered.

The company has 20 branch offices throughout the world.



 Each branch office belongs to one of six regions.

o No region contains more than four branch offices.



Each branch office has 800 users

Each branch office has a single domain controller, which is configured as a 
global catalog server.

Exchange ORG needs to match the business requirements,

Each Exchange server can contain



 4 Storage groups

o Inside each storage group you include 5 databases



In total you can split your users in 20 databases to speeds the recover of any 
Exchange crash using new Exchange feature Recovery Storage Group

They tell to you users will connect to a Microsoft Outlook Web Access server and 
that this server will be hosted at their local branch office.



The have one central office + 6 regions + each branch do not contain more 4 
offices this means

7 Exchange servers (1 server for main office plus one server per region)



 1 Server in the Central site

o Four storage groups

 1 Database per group

 1000 users

o 200 user per database

 20 Branch offices inside 6 regions (AD sites)

o 1 Server per region

 4 storage groups per server

 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 storage group 
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 total) 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 you can recover each database in a reasonable amount 
of time.



Key differences between Exchange 2003 Standard Edition and Exchange 2003 
Enterprise Edition



Feature Exchange 2003 Standard Edition Exchange 2003 Enterprise Edition



Storage group support 1 storage group 4 storage groups

Number of databases per storage 2 databases group 5 databases



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



 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



Exchange Full Administrator



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. A user who has Exchange Full Administrator permissions has 
the following rights:



Organization Rights



 Full Control permissions on the MsExchConfiguration container (this object and 
its subcontainers).

 Deny Receive-As permissions and Send-As permissions on the Organization 
container (this object and its subcontainers).

 Read permissions and Change permissions on the Deleted Objects container in 
the Configuration naming context (Config NC) (this object and its subcontainers).



Administrative Group Rights



 Read, List object, and List contents permissions on the MsExchConfiguration 
container (this object only).

 Read, List object, and List contents permissions on the Organization container 
(this object and its

 subcontainers).

 Full Control, Deny Send-As, and Deny Receive-As permissions on the 
Administrator Groups container (this object and its subcontainers).

 Full Control permissions (except for Change) on the Connections container 
(this object and its subcontainers).

 Read, List object, List contents, and Write properties permissions on the 
Offline Address Lists container (this object and its subcontainers).



Note:

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 and D uses suggests to put multiple regions on each server, that's 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" do 
not need to be backed up and recovered, letter A is the best choice.



Effect of Having Circular Logging Turned On

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. Typically, this represents the 
majority of the potential log data, because by definition, the total size of the 
active transactions is less than the total amount of random access memory (RAM) 
on a given computer. Thus, when circular logging is on, the system still has 
complete recoverability with respect to hard and soft failures. The element that 
is sacrificed is the extra protection against media failure. Also, because the 
transaction logs are used for incremental and differential backups, these backup 
methods are no longer valid. If you try to do an incremental or a differential 
backup on a server that has circular logging enabled, Microsoft Windows NT 
Backup generates an error message that informs you that the incremental or 
differential backup cannot be done.



When circular logging is enabled you can see more than one transaction log in 
the log directory. For example, if a user sends a message with a 25-MB 
attachment, because the maximum log file size is 5 MB, four logs are likely to 
be created to process this transaction in addition to the Edb.log file. That is, 
you see Edb00001.log, Edb00002.log, Edb00003.log, and Edb00004.log. After the 
transaction is processed completely, these log files remain until a full backup 
is performed on the database, at which time they are removed. If the number of 
log files generated with circular logging enabled is equal to or greater than 
four (not including Edb.log) the logs remain until a full backup is performed.



When circular logging is enabled, high-volume conditions also cause the number 
of log files to increase.



Because the inactive portion of a transaction log is only discarded and reused 
after the Edb.chk file has moved past the inactive portion, many transactions 
may build up in the logs before they can be processed. If the total number of 
unprocessed transactions exceeds 5 MB and more continue to build up, another log 
file (for example, Edb00001.log) is created to hold these transactions. If the 
high-volume conditions continue, the log files continue to increase in number 
until the transactions can be processed completely. After the transaction 
processing catches up and the Edb.chk file is advanced past the transactions in 
these log files, these log files become inactive and again are not be removed 
until a full backup is performed. Other possible causes of log files growing 
with circular logging enabled are faulty small computer system interface (SCSI) 
controllers or hard drives that cause the transactions not to be completed in a 
timely manner, and the Edb.log files being held open exclusively by another 
process other then

Jet (for example, backup programs, copying operations, and so on).

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:

Chief Executive Officer

I know that the antivirus software for the Exchange system is purchased on a 
server-by-server 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 dies 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 have only a minimal 
impact on the ability of users in each branch office to send and receive e-mail 
while they are in the office.



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.

Question 6.

You need to design access to e-mail by Internet users. What should you do?



A. Configure front-end servers to use HTTP to communicate with back-end servers.

B. Configure the internal firewall to allow IPSec traffic between front-end and 
back-end Exchange 

servers.

C. Require all users to encrypt all outbound e-mail messages.

D. Issue digital certificates to all remote users Require the certificates to be 
used when 

authenticating to Outlook Web Access.
