Your company has four regional offices and 20 branch offices. The regional offices connect to each other by
using a 30-Mbps WAN link. Each branch office connects to its nearest regional office by using a 1-Mbps WAN
link.
The network contains an Active Directory forest. The forest contains a domain controller in each office. Each
office maps to an Active Directory site. Each branch office site connects to the nearest regional office site by
using an Active Directory site link.
You have an Exchange Server 2013 organization that contains one server in each office.
You need to implement a messaging solution to meet the following requirements:
The users in the branch offices must only be able to send email messages that are up to 2 MB to the users
in the other offices.
The users in the regional offices must be prevented from sending email messages that are larger than 5 MB
to the users in any of the regional offices.
Which cmdlet should you run?

A.
Set-TransportRule

B.
Set-ADSite

C.
Set-AdSiteLink

D.
Set-RoutingGroupConnector

Explanation:
NOT A
Does not relate to message size
Set-TransportRule
Use the Set-TransportRule cmdlet to modify an existing transport rule in your organization.
For information about the parameter sets in the Syntax section below, see Syntax.EXAMPLE 1
This example modifies the Sales Team Disclaimer transport rule. Modifying the value of one predicate doesn’t
affect other predicates used in the rule’s conditions or exceptions and doesn’t affect actions on the same rule.
This example sets the FromMemberOf parameter to a value of Sales-Group, which specifies that the rule is
applied if the sender of the message is a member of the Sales-Group distribution group.
Set-TransportRule “Sales Team Disclaimer” -FromMemberOf “Sales-Group”
NOT B
Does not relate to message size
Set-ADSite
Use the Set-AdSite cmdlet to configure the Exchange settings of Active Directory sites.
EXAMPLE 1
This example configures the Active Directory site named Default-First-Site-Name as a hub site.
Set-AdSite Default-First-Site-Name -HubSiteEnabled $true
NOT D
Does not relate to message size
Set-RoutingGroupConnector
With routing groups and Routing Group connectors you can consolidate communication between servers by
designating bridgehead servers that act as communication points between routing groups. For example, your
organization may have a remote site connected through a wide-area-network (WAN) link to your main office. In
this example, you can use a Routing Group connector to route Exchange traffic between a server at your main
office and a server at your remote site.
C
The only command that deals with message size.
Set-AdSiteLink
Use the Set-AdSiteLink cmdlet to assign an Exchange-specific cost to an Active Directory IP site link. You can
also use this cmdlet to configure the maximum message size that can pass across an Active Directory IP site
link.
EXAMPLE 1
This example assigns an Exchange-specific cost of 25 to the IP site link DEFAULT_IP_SITE_LINK and
configures a maximum message size limit of 10 MB on the IP site link.
Set-AdSiteLink DEFAULT_IP_SITE_LINK -ExchangeCost 25 -MaxMessageSize 10MB
