Testlet 1
Topic 4, A Datum Corporation
Overview
A)
Datum Corporation is an airline catering company that has 8,000 users. A. Datum has three main offices.
The offices are located in Detroit, Chicago, and New York.
Existing Environment
Active Directory Environment
The network contains an Active Directory forest named adatum.com. The forest contains a single domain. All
domain controllers run Windows Server 2012.
Each main office contains two domain controllers. Each office is configured as an Active Directory site.
The functional level of the forest is Windows Server 2012.
Network Infrastructure
The offices connect to each other by using a dedicated WAN link. Only the office in New York and the office in
Detroit connect directly to the Internet. Each office has a firewall.
The public DNS records for A. Datum are configured as shown in the following table.

The external interface for the firewall in the New York office is configured to use an IP address of
131.107.1.200 and to pass inbound traffic on port 25 and port 443 to EX2.
The external interface for the firewall in the Detroit office is configured to use an IP address of 131.107.2.200
and to pass inbound traffic on port 443 to EX4.
The Active Directory site is configured as shown in the Sites exhibit. (Click the Exhibit button.)
Exchange Server Organization
A)
Datum has an Exchange Server 2013 organization that contains two servers. The servers are
configured as shown in the following table.

Each server contains 15 mailbox databases.
Users use the name mail.adatum.com to connect to their mailbox from the Internet. The users use the FQDN of
the servers to connect from the internal network.
AM of the users in the Detroit office have a mailbox hosted on EX2.
The default email address policy contains a single email address format of @adatum.com.
A separate Send connector exists for the Chicago office and the New York office. The local servers in each
office are the only source servers in each Send connector.
The New York office is configured as a hub site. Antimalware filtering is disabled on EX1 and EX2.
Problem Statements
A)
Datum identifies the following issues:
Users in the Detroit office report that sometimes, Microsoft Outlook takes a long time to open.
During a recent storage failure, administrators failed to restore the latest backup and lost all of the email
messages from the previous 48 hours.
Users report that the email messages sent to some Internet domains are not received. Users in the Chicago
office report that some of their email messages generate a non-delivery report (NDR).
The help desk in the New York office reports that its most common Exchange-related task is to restore
email messages that were deleted by users more than 14 days ago. The task requires time-consuming
restore operations by the help desk.
Requirements
Business Requirements
A)
Datum wants to provide users with the ability to access their email from Internet Explorer 10, even when the
users are disconnected from the network. This ability must only be available if the users log on to Outlook Web
Access by using the Private option.
Planned Changes
You plan to deploy three additional Exchange Server 2013 servers. The servers will be configured as shown in
the following table.

After the planned deployment, all of the mailboxes of the Detroit office users will be moved to EX3. All of the
Detroit office users will use the name detroitmail.adatum.com when they connect from the Internet and the
name ex4.adatum.com when they connect from the internal network.
Technical Requirements
A)
Datum identifies the following technical requirements:
All existing and future mailboxes must be limited to 5 GB of storage.
Antimalware and anti-spam filtering must be enabled for the entire Exchange Server organization.If storage for the mailbox database fails, administrators must be able to recover email messages handled by
transport services for to the last five days.
Only the members of a group named Executives must be able to schedule meetings in a room mailbox
named Boardroom. Meeting requests must not be moderated.
All of the servers in the New York office that have the Client Access server role installed must be accessed
by using a load balancing solution that can mark a server as down if a specific URL on the server is
unavailable.
Mailbox Creation Requirements
A)
Datum identifies the following requirements for creating new mailboxes:
All mailboxes must automatically have single item recovery enabled.
All mailboxes must automatically have the Exchange ActiveSync feature disabled.

HOTSPOT
You need to recommend a solution to meet the technical requirements for email message recovery.
Which command should you include in the recommendation? (To answer, configure the appropriate options in
the answer area.)
Hot Area:

Answer:

Explanation:
Set-MailboxTransportService
Use the Set-MailboxTransportService cmdlet to view the transport configuration information for the Mailbox
Transport service on Mailbox servers.
Example 1
This example sets the ReceiveProtocolLogPath parameter to C:\\SMTP Protocol Logs\\Receive.log for the
Mailbox Transport service on server Mailbox01.
Set-MailboxTransportService Mailbox01 -ReceiveProtocolLogPath “C:\\SMTP Protocol Logs\\Receive.log”
Set-TransportConfig
Use the Set-TransportConfig cmdlet to modify the transport configuration settings for the whole Exchange
organization.
EXAMPLE 1
This example configures the Exchange organization to forward all DSN messages that have the DSN codes
5.7.1, 5.7.2, and 5.7.3 to the postmaster email account.
Set-TransportConfig -GenerateCopyOfDSNFor 5.7.1,5.7.2,5.7.3
Set-TransportServer
Use the Set-TransportServer cmdlet to set the transport configuration options for the Transport service on
Mailbox servers or for Edge Transport servers.
EXAMPLE 1
This example sets the DelayNotificationTimeout parameter to 13 hours on server named Mailbox01.Set-TransportServer Mailbox01 -DelayNotificationTimeout 13:00:00
Set-TransportService
Use the Set-TransportService cmdlet to set the transport configuration options for the Transport service on
Mailbox servers or for Edge Transport servers.
EXAMPLE 1
This example sets the DelayNotificationTimeout parameter to 13 hours for the Transport service on a Mailbox
server named Mailbox01.
Set-TransportService Mailbox01 -DelayNotificationTimeout 13:00:00
-MaxDumpsterTime
This parameter isn’t used by Microsoft Exchange Server 2013. It’s only used by Microsoft Exchange 2010
servers in a coexistence environment.
-MessageExpirationTimeout
Not a parameter of Set-TransportConfig
-SafetyNetHoldTime
Parameter of Set-TransportConfig
The SafetyNetHoldTime parameter specifies how long a copy of a successfully processed message is retained
in Safety Net.
Unacknowledged shadow copies of messages auto-expire from Safety Net based on adding the values of the
SafetyNetHoldTime parameter and the MessageExpirationTimeout parameter on the Set-TransportService
cmdlet.
To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s =
seconds.
The default value is 2.00:00:00 or 2 days.
-ShadowMessageAutoDiscardinterval
The ShadowMessageAutoDiscardInterval parameter specifies how long a server retains discard events for
shadow messages.
A primary server queues discard events until queried by the shadow server. However, if the shadow server
doesn’t query the primary server for the duration specified in this parameter, the primary server deletes the
queued discard events.
To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s =
seconds.
Valid input for this parameter is 00:00:05 to 90.00:00:00. The default value is 2.00:00:00 or 2 days.
STEPS
1. Set-TransportConfig. Need to use Safety Net and this is a parameter of Set-TransportConfig
2. SafetyNetHoldTime Need to configure Safety Net.
How Safety Net Works
Safety Net can be considered to be having two parts- Shadow Redundancy and Safety Net Redundancy.
While the safety Net keeps a redundant copy of a message after it is successfully processed, shadow
redundancy keeps a redundant copy of the message which is in transit. All features of shadow redundancy like
transport high availability boundary, primary messages, primary servers, shadow messages and shadow
servers will be applicable to Safety Net.
The Primary Safety Net is applicable for a Mailbox server that holds the primary message before the Transport
service completely processes the message. Once the processing of the message is over, the primary server
moves the message to the Primary Safety Net from the active queue on the same server.
The Shadow Safety Net is applicable to the Mailbox server which holds the shadow message. Once the
shadow server receives the information that the primary server has successfully processed the primary
message, the shadow message is moved to the shadow safety net from the shadow queue on the server. For
the Shadow Safety Net operation, shadow redundancy should be enabled, and shadow redundancy is enabled
by default in Exchange 2013.
