You have an Exchange Server 2013 organization that contains two Edge Transport servers. The Edge
Transport servers are configured to perform recipient filtering.
You deploy a new Edge Transport server named Edge3.
You need to ensure that Edge3 performs recipient filtering.
What should you do?

A.
Create a new Edge Subscription for Edge3.

B.
Run the Set-TransportConfig cmdlet on Edge3.

C.
Export the Edge Subscription from an existing Edge Transport server and import the Edge Subscription to
Edge3.

D.
Run the ExportEdgeConfig.ps1 and the ImportEdgeConfig.ps1 scripts.

Explanation:
We copy the configuration from an existing Edge Transport server with the ExportEdgeConfig.ps1 script and
apply to new server Edge3 with ImportEdgeConfig.ps1 script.
Note: Configure Edge Transport server using cloned configuration
You can use the provided Exchange Management Shell scripts (located in %ExchangeInstallPath%Scripts) to
duplicate the configuration of an Edge Transport server. This process is referred to as cloned configuration.
Cloned configuration is the practice of deploying new Edge Transport servers based on configuration
information from a previously configured source server. The configuration information from the previously
configured source server is copied and exported to an XML file, which is then imported to the target server.
Two Shell scripts are used to perform cloned configuration tasks:
* ExportEdgeConfig.ps1 Exports all user-configured settings and data from an Edge Transport server and
stores that data in an XML file.
* ImportEdgeConfig.ps1 During the validate configuration step, the ImportEdgeConfig.ps1 script checks the
exported XML file to see whether the server-specific export settings are valid for the target server.
Incorrect answers:
Not A: We do not need to create a new Edge subscription.
Not B: The Set-TransportConfig cmdlet is used to modify the transport configuration settings for the whole
Exchange organization, but we just to copy the configuration of an Edge Transport server.
Not C: There are no commands to export and import Edge subscriptions.
