QUESTION 1
You work as the Exchange administrator at Certkingdom.com. The Certkingdom.com network has an Active
Directory domain named Certkingdom.com.
The Certkingdom.com Exchange organization contains two Exchange Server 2003 computers named
ABC-SR11 and ABC-SR12 respectively. ABC-SR11 is configured as the mailbox server and ABCSR12
is configured as the front-end server. ABC-SR12 has Microsoft Outlook Web Access over
SSL installed to allow Certkingdom.com employees to access their e-mail.
The Certkingdom.com intranet is connected to the Internet via a firewall. When several employees
complain that they are unable to access ABC-SR12, you investigate the issue and find that
employees are able to access Outlook Web Access using HTTP or HTTPS.
You have been instructed to make sure that the Certkingdom.com employees are only able to use HTTPS
to access Outlook Web Access.
Which of the following actions should you take?

A. You should reconfigure the firewall to allow Certkingdom.com employees to access port 443 on ABCSR12,
and then configure the default Web site on ABC-SR12 to require SSL connections.
B. You should reconfigure the firewall to allow Certkingdom.com employees to access port 80 on ABCSR12,
and then configure the default Web site on ABC-SR12 to use port 443 for SSL connections.
C. You should reconfigure the firewall to allow Certkingdom.com employees to access port 993 on ABCSR12,
and then configure the default Web site on ABC-SR12 to require SSL connections and 128-
bit encryption.
D. You should reconfigure the firewall to allow Certkingdom.com employees to access port 143 on ABCSR12,
and then configure the Exchange HTTP virtual server on ABC-SR12 to enable forms-based
authentication for Outlook Web Access.

Answer: A

Explanation: SSL utilizes port 443. The external firewall does not currently allow traffic on port
443 to pass. Opening up this port will take care of that issue. The default OWA site is currently not
correctly setup to use HTTPS. This is why internal clients can connect to OWA using HTTP.
Modifying the security on the OWA web site will solve this problem.

QUESTION 2
You work as the network Exchange administrator at Certkingdom.com, who has their headquarters located
in Miami. The Certkingdom.com network has an Active Directory domain named Certkingdom.com. All servers on
the Certkingdom.com network run Windows Server 2003 and all client computers run Windows XP
Professional.
The Certkingdom.com network includes a server named ABC-EX01, which runs Microsoft Exchange
Server 2003.
Certkingdom.com recently entered into partnership with Weyland Industries, who has their office located in
Toronto. Part of the network in the Toronto office is configured as an Active Directory site within
the Certkingdom.com domain. A server named ABC-EX02 is configured to run Microsoft Exchange Server
2003 and located in the Toronto office. The two Exchange servers are configured in separate
routing groups connected via a routing group connector. The Toronto and Miami offices are
connected to each other via a leased line connection.
You receive instruction from Certkingdom.com to configure an ISDN-dialup connection as a backup
connection in the event that the leased line connection becomes unavailable.
During the course of your maintenance you discover that the ISDN dial-up connection is not used
as a backup connection, but is used exclusively by the routing group connector.
Certkingdom.com wants you to make sure that the leased line connection is used as the primary
connection, and that the ISDN connection is used only if the leased line connection fails.
Which of the following actions should you take?

A. You should configure ABC-EX01 and ABC-EX02 to be in the same Active Directory site.
B. You should configure ABC-EX01 and ABC-EX02 to be in the same routing group.
C. You should have a lower IP route cost assigned to the ISDN link and a higher link cost to the
leased line link.
D. You should configure ABC-EX02 to use ABC-EX01 as a smart host.
E. You should have a lower IP route cost assigned to the leased line link and a higher link cost to
the ISDN link.

Answer: E

Explanation: It is possible that the administrator reversed the values of the cost on the
connections because IP route costs are used to set the preference levels between two routes to
the same destination.

QUESTION 3
You work as the Exchange administrator at Certkingdom.com. The Certkingdom.com network has an Active
Directory domain named Certkingdom.com. Certkingdom.com employs Exchange Server 2003 as its messaging
system. All servers on the Certkingdom.com network run Windows Sever 2003 and all Exchange servers
run Exchange Server 2003.
The Exchange organization contains an Exchange server named ABC-SR31, which is used to
pass SMTP e-mail messages between Certkingdom.com and the Internet and also stores the mailboxes of
all Certkingdom.com’s employees. The intranet is connected to the Internet via a firewall.
When several employees complain that they continuously receive numerous unwanted e-mail
messages, you investigate the issue and find that the unwanted e-mail messages received by
Certkingdom.com’s employees are the same. You also notice that the messages are being sent to a
universal distribution group in the Certkingdom.com domain.
You must configure the network so that distribution groups are prevented from sending e-mail
messages from the Internet to the Certkingdom.com users. Your solution must enable the Certkingdom.com users
to continue to send and receive legitimate e-mail messages.
Which of the following is the best solution?

A. You should consider having the universal distribution groups converted to Domain Local
Distribution groups.
B. You should consider having the Exchange Attributes removed from the universal distribution
groups.
C. You should consider having the distribution groups configured to only permit e-mail messages
from authenticated users.
D. You should consider having the membership of the universal distribution groups hidden.

Answer: C

Explanation: Your best option in this scenario would be to select Option C. The universal group is
used for mail distribution in your organization. You can configure the distribution group to accept
mail from authenticate users only to stop receiving spam.
Incorrect answers
A: Converting the universal groups to domain local security groups on its own will not protect you
against unsolicited mail. The security groups will still receive email
B: Removing the Exchange Attributes will remove the email address which would prevent
Certkingdom.com users from sending email to the groups.
D: Hiding the group membership will not protect you against unsolicited mail. The groups will still
receive email.

QUESTION 4
You work as the network Exchange administrator at Certkingdom.com. The Certkingdom.com network has an
Active Directory domain named Certkingdom.com. All servers on the Certkingdom.com network have Windows
Server 2003 installed and all workstations have Windows XP Professional installed.
The Certkingdom.com network contains an Exchange 2003 server named ABC-EX01, which hosts
thousands of mailboxes in a single storage group. ABC-EX01 is equipped with a single RAID-5
device, which is configured as a single logical drive. ABC-EX01 is additionally equipped with a
high-end CPU and has a 2GB of RAM.
During the course of the day the Certkingdom.com network users with mailboxes hosted on ABC-EX01
complain that at times of peak usage their email-services become considerably slower and it takes
longer for messages to be sent and opened using Microsoft Outlook. You have recently received
instruction from the Certkingdom.com network CIO to monitor the performance and you receive the values
shown in the following exhibit:

You are required to improve the performance of e-mail for the network Exchange users on ABCEX01.
What should you do?

A. You should consider having a full-text index created on the mailbox store
B. You should consider having a new volume created on the existing RAID-5 device and move the
Exchange transaction logs to the new volume
C. You should consider having a new RAID device added and the Exchange transaction logs
moved to the new device
D. You should consider installing additional RAM
E. You should consider installing an additional processor

Answer: C

Explanation: The performance results indicate that the hard disk usage is very high and the other
counter values are within acceptable limits. All changes to the Exchange databases are recorded
first in the transaction logs.

QUESTION 5
You work as the Exchange administrator at Certkingdom.com. The Certkingdom.com Exchange organization has
includes a solitary server named ABC-EX01 that has Exchange Server 2003 installed. All
Certkingdom.com users make use of Microsoft Outlook to send and receive e-mail messages.
ABC-EX01 is equipped with dual CPUs and 2 GB Random Access Memory (RAM). ABC-EX01 is
configured to host a storage group that contains one mailbox store.
You receive reports that opening Outlook takes too long, and that every e-mail message being
sent or opened takes too long. You monitor the ABC-EX01 and find that the inadequate RAM
results in the primary bottleneck, which then results in sluggish performance. You, therefore,
increase ABC-EX01’s RAM to 4 GB RAM. However, the Certkingdom.com users continue to report
sluggish Outlook performance.
Which of the following actions should you take to improve ABC-EX01’s performance?

A. You should increase the size of the virtual memory to 6GB.
B. You should place an additional switch that increases user mode memory usage to the Boot.ini
file in the mailbox servers.
C. You should increase the priority of the store.exe process in Task Manager.
D. You should set up an additional mailbox store on the server. Then divide the existing mailboxes
between the old and the new mailbox store.

Answer: B

Explanation: If you have more than 1 GB of physical memory installed on a server that is running
Exchange Server 2003, you must make sure that Exchange Server 2003 can make efficient use of
that memory.
If you are running Exchange Server 2003 on a Windows Server 2003-based computer, and if the
/3GB switch is set, Microsoft recommends that you set the /USERVA=3030 parameter in the
Boot.ini file. This configuration option increases the virtual address space.
