Each office is configured as an Active Directory site.
All user accounts are in an organizational unit (OU) based on their department. All users are

are configured as shown in the following table.

The mailbox databases are mounted on the Exchange servers shown in the following table.

All of the mailboxes of the users in the executives department are mounted on DB3.
A public folder database named PF1 is mounted on EX5.
The Exchange Server organization has the following configurations:

mailbox named Legal. Legal is enabled for InPlace Hold. Legal is the only mailbox on DB2.
• All inbound and outbound email messages to
and from the Internet are routed through EX1.

are secured by using Mutual TLS.
• All public folders are stored in PF1.
All users connect to their mailbox by using Microsoft Outlook 2013 and Outlook Web App.
Fabrikam has an Exchange Server 2013 organization.
Problem Statements
Trey Research identifies the following issues:
• After a change to a certificate, users report that
email messages sent to Fabrikam are not
delivered.
• The storage for DB3 fails. The storage will be
offline for the next two days.
Requirements
Planned Changes
Trey Research plans to implement the following changes:
• Move all public folders to an Exchange Server
2013 server. The solution must ensure that all
users cannot modify the public folders stored on
EX5 after the planned move.• Integrate Unified Messaging (UM) services with
the Lync Server 2013 infrastructure.
Collaboration Requirements
Custom recipient MailTips created in the Exchange Server organization of Trey Research
must be visible to the users at Fabrikam. The solution must ensure that administrators can
define a subset of users who can share their MailTips.
Auditing Requirements
The following actions must be audited for actions in the Legal mailbox only:
• Delegate – Purge mailbox content
• Delegate – Transfer file between folders
• Administrator – Messages sent by administrator
• Administrator – Open any content within the
mailbox
Security Requirements
Trey Research identifies the following security requirements:
• Ensure that the users in the finance department
can protect email messages from being altered in
transit, regardless of the recipient.
• Prevent the email messages sent to the users in
the human resources department from being
forwarded to external recipients.
• Prevent the audio files in voice mail message
marked as Private from being extracted from
email messages.
• Redirect email messages that contain social
security information to the legal department.
Compliance Requirements
Trey Research identifies the following compliance requirements:
• All users must be notified before they send an
email message that contains any five bank
account numbers to an external recipient. The
users must be able to override the requirement if
they have a valid business reason to send the
email message.
• Users must use a custom message classification
when they send email messages that contain
information about the planned acquisition of
Fabrikam.
• Only the users in the legal department must be
able to use eDiscovery to view the contents of
email messages sent by the finance department
users.

HOTSPOT
You are attempting to resolve the email delivery issue for Fabrikam.
You need to identify which certificate is being used by the servers in the Exchange Server
organization of Fabrikam.
In which directory on EX1 should you review the log files? (To answer, select the appropriate
directory in the answer area.)

Answer:

Explanation:
* Scenario: After a change to a certificate, users report that email messages sent to Fabrikam are not
delivered.
* ProtocolLog
Protocol logging records the SMTP conversations that occur between messaging servers as part of
message delivery. These SMTP conversations occur on Send connectors and Receive connectors that
exist in the Front End Transport service on Client Access servers, the Transport service on Mailbox
servers, and the Mailbox Transport service on Mailbox servers. You can use protocol logging to
diagnose mail flow problems.
