Answer: 
Explanation:
Note:
Box 1: make a shadow copy of the message on another server
From the exhibit we see that: ShadowRedundacyEnable: True
With shadow redundancy in Microsoft Exchange Server 2013 the transport server makes a redundant copy of
any messages it receives before it acknowledges successfully receiving the message back to the sending
server.
Box 2: two days
In the exhibit we see: ShadowMessageAutoDiscardInterval : 2.00:00:00
This means two days.
Note: Use the ShadowMessageAutoDiscardInterval parameter of the Set-TransportConfig cmdlet to configure
the maximum age for shadow messages in your organization. By default, shadow messages are discarded
automatically after two days.
This example reduces the retention period of shadow messages to four hours for your organization.
Set-TransportConfig -ShadowMessageAutoDiscardInterval 04:00:00
