Topic 6, Trey Research
Overview
Trey Research is a pharmaceutical company that has 10,000 users. Most of the users work
remotely, including the users in the finance department. The finance department users reside in
an organizational unit (OU) named Finance.
Trey Research purchases a partner pharmaceutical company named Fabrikam, Inc. Fabrikam has
2,000 users and hosts its own Exchange Server 2010 organization.
Existing Environment
Active Directory Environment
The network of Trey Research contains an Active Directory forest. The forest contains an empty parent domain
named treyresearch.com and a child domain named main.treyresearch.com. The forest contains one site
named DefaultSite.
The Trey Research network and the Fabrikam network connect to each other by using a WAN link. A two-way
trust exists between the Trey Research and Fabrikam networks.
Trey Research Exchange Server Organization
Trey Research has an Exchange Server 2013 organization that contains four servers. The servers are
configured as shown in the following table.
EX1 and EX2 are the members of a database availability group (DAG) named DAG1.
Trey Research has three databases named DB1, DB2, and DB3. DB1 and DB2 replicate between all of the
servers in DAG1. DB3 is mounted on EX4.
The storage on EX1 and EX2 is configured as shown in the following table.
The Exchange Server 2013 servers at Trey Research are configured as follows:
EX3 and EX4 perform spam filtering.
The public folder hierarchy mailbox is homed on DB3.
Each mailbox database contains a public folder mailbox.
HTTP traffic is load balanced by using a Layer 4 hardware load balancer.
The hardware load balancer uses the OWA virtual directory for health monitoring.
On EX1 and EX2, the mailbox database files and log files are stored on volume mount points.
IMAP is enabled on EX4 to download email messages for a custom help desk application.
Remote users access their mailbox by using Outlook Web App and Exchange ActiveSync.
The custom help desk application uses a service account that has a display name of Help Desk and an
SMTP address of helpdesk@treyresearch.com.Fabrikam Exchange Server Organization
Fabrikam has an Exchange Server 2010 organization that contains two servers. The servers are configured as
shown in the following table.
Fabrikam plans to implement the address rewrite feature to change the SMTP domain name of all outbound
email to use the treyresearch.com SMTP suffix.
Problem Statements
Trey Research identifies the following issues:
Recently on EX2, Volumel failed for three days. Once the volume was repaired, reseeding the database
from EX1 took more than six hours.
You recently discovered that when the MSExchangeOWAAppPool application pool on EX3 was in a stopped
state, the hardware load balancer marked EX3 as offline.
Users report that during the installation of updates on the Exchange Server 2013 servers, the users lost
access to their mailbox and were unable to modify public folders.
Several finance department users store sensitive data on their mobile device. The legal department requires
that Exchange ActiveSync be disabled for all of the finance department users.
An Active Directory administrator reports that the domain controllers in the treyresearch.com domain are
overused. The administrator requests that the Exchange Server 2013 servers only use the domain
controllers in the main.treyresearch.com domain.
Requirements
Business Goal
The legal department requires that the finance department users have a segmented view of the global address
list (GAL) that only shows recipients in the finance department
Planned Changes
Trey Research plans to implement the following spam confidence level (SCL) configurations:
Block email messages when the SCL score is 9.
Move the email messages to the postmaster mailbox when the SCL score is 7.
Block email messages and send a non-delivery report (NDR) when the SCL score is 8.
Resource Utilization Requirements
Users report that their connection to Outlook Web App is slow since the deployment of IMAP on EX4. The
users do not report that they experience performance issues when they use their mobile device.
Trey Research reports that the IMAP service is not business critical and must not have a higher priority over
hardware resources than Outlook Web App. On EX4, Outlook Web App has the same priority over hardware
resources as Exchange ActiveSync.
###EndCaseStudy###

a different volume.
Which command should you run?
A.
Set-MailboxDatabase
B.
Set-MailboxDatabaseCopy
C.
Set-DatabaseAvailabilityGroup
D.
Set-MailboxAutoRcplyConfigu ration
Explanation:
Exchange 2013 Auto Reseed
Exchange 2013 includes a great new high availability feature that is part of the Database Availability Group.
This feature will reseed a database in case of disk failure from a “pool” of volumes that were pre-configured for
this propose. In case that the failed drive contained an active database, Exchange will failover to one of the
other passive copies and reseed the database. In case that the failed drive contained one of the passive
copies, Exchange will reseed the database on the same drive.
AutoReseed reduces the need for Exchange Administrator or any other operator, to be on site at the moment of
the drive crash and replace it as soon as he can in order to preserve the healthy copies structure.
