What should you include in the recommendation?

You are a network administrator for a school named Graphic Design Institute. The network contains
an Exchange Server 2010 Service Pack 1 (SP1) organization named graphicdesigninstitute.com.
Approximately 50,000 students enroll at the school each year. The students use Outlook Anywhere.
At the beginning of each academic year, you plan to create 25 new mailbox databases to host all of
the student mailboxes. You need to recommend which configurations must be performed on each
new mailbox database. The solution must meet the following requirements:
• Minimize the amount of disk space required on the Mailbox servers.
• Ensure that the students can search for email addresses and office locations of teachers when they
cannot access the school network.
What should you include in the recommendation? (Choose all that apply.)

A.
Modify the maintenance schedule of each mailbox database.

B.
Enable local continuous replication (LCR).

C.
Enable circular logging for each mailbox database.

D.
Configure the offline address book (OAB) properties of each mailbox database.

E.
Enable disk quotas for each volume.

F.
Create an offline address book (OAB) virtual directory for each mailbox database.

Explanation:
C and D are the best answers however please note that depending on how you will distribute your
offline address books you might create a OAB virtual directory.
Although it is not recommend it as a best practice, you can configure Exchange to save disk space by
enabling circular logging. Circular logging allows Exchange to overwrite transaction log files after the
data that the log files contain has been committed to the database.
In Exchange 2010, circular logging is disabled by default. By enabling it, you reduce drive storage
space requirements. However, without a complete set of transaction log files, you can’t recover any

data more recent than the last full backup. Therefore, in a normal production environment, circular
logging isn’t recommended.
An offline address book (OAB) in Exchange Server 2010 is a copy of an address book that’s been
downloaded so that an Outlook user can access the information it contains while disconnected from
the server. Exchange administrators can choose which address books are made available to users
who work offline, and they can also configure the method by which the address books are
distributed (Web-based distribution or public folder distribution).
Use the EMC to configure OAB properties
You need to be assigned permissions before you can perform this procedure. To see what
permissions you need, see the “Offline address books” entry in the Mailbox Permissions topic.
In the console tree, navigate to Organization Configuration > Mailbox.
In the result pane, click the Offline Address Book tab, and then select the offline address book that
you want to configure.
In the action pane, click Properties.
Use the General tab to view OAB properties and to set the update interval for the OAB.
Name This unlabeled box at the top of the tab displays the OAB name. You can modify this name.
Generation server This read-only field displays the OAB generation server. The OAB generation
server is the Mailbox server on which the OABs are generated. If you want to specify a different
generation server, use the Move-OfflineAddressBook cmdlet with the Server parameter. For more
information, see Move-OfflineAddressBook.
Default offline address book This read-only field displays a True or False status to indicate whether
the selected OAB is the default OAB. If this isn’t the default OAB, and you want to set it as the
default, right-click the OAB in the result pane, and then click Set as Default.
Modified This read-only field displays the last date and time that the OAB was modified.
Update Schedule This list displays the time and interval for the regularly scheduled update.
To customize the schedule, select Use Custom Schedule from the list, and then click Customize to
open the
Schedule dialog box and specify the schedule you want.
Use the Address Lists tab to select the address lists you want to include in the OAB. If you want to
include a global address list (GAL) other than the default GAL, you must use the Shell.
Include the default Global Address List Select this check box to include the default GAL in the OAB.
Include the following address lists Select this check box to add address lists to or remove address
lists from the OAB.
Click Add to select one or more address lists to add to the OAB.
Click to remove the selected address list from the OAB.
Use the Distribution tab to specify the client support and OAB distribution points for the OAB.
Client Support Select the OAB version that will be generated for the version of Outlook that is used
by your Exchange organization. If you have more than one version of Outlook in your organization,
you can select one or more of the following versions:
Outlook 98 SP1 or earlier (Version 2)
Outlook 98 SP2 or later (Version 3)
Outlook 2003 SP2 or later (Version 4)
If you don’t select one of the Client Support options, Version 4 will be generated.
Distribution Points OAB distribution is the method by which the OAB can be accessed by users when
they are working remotely or over a dial-up connection. To distribute the OAB, administrators can
use Web-based distribution, public folder distribution, or both. An OAB distribution point is the HTTP
Web address or public folder where client computers can download an OAB.
You can select one or both of the following check boxes:

Enable Web-based distribution Select this check box to enable Web-based distribution. Web-based
distribution is the distribution method by which Outlook 2007 or later clients that are working offline
or through a dial-up connection access the OAB. With Web-based distribution, a Client Access server
will contain an OAB virtual directory for Web distribution purposes.
Click Add to specify the virtual directory or directories from which you want to distribute the OAB.
Click to remove the selected virtual directory from the OAB.
Enable public folder distribution Select this check box to enable public folder distribution. Public
folder distribution is the distribution method by which Outlook 2003 or earlier clients that are
working offline or through a dial-up connection access OABs.
