You have an Exchange Server 2013 organization that contains two servers. The servers are
configured as shown in the following table.
You need to create a new database availability group (DAG) that contains EX1 and EX2. Which three
actions should you perform?
To answer, move the three appropriate actions from the list of actions to the answer area and
arrange them in the correct order.
Answer: 
Explanation:
Box 1: Add the Exchange Trusted Subsystem universal security group to the local Administrators group on Server1.
Box 2: Create a new DAG and specify Server1 as the file share witness.
Box 3: Add EX1 and EX2 to the DAG.
Note:
* A database availability group (DAG) is a set of up to 16 Microsoft Exchange Server 2013 Mailbox
servers that provide automatic database-level recovery from a database, server, or network failure.
When a Mailbox server is added to a DAG, it works with the other servers in the DAG to provide
automatic, database-level recovery from database, server, and network failures.
* You can specify a name for the DAG and the witness server that you want to use, and leave the
Witness directory field empty. In this scenario, the task will create the default witness directory on
the specified witness server.
* If the witness server you specify isn’t an Exchange 2013 or Exchange 2010 server, you must add the
Exchange Trusted Subsystem universal security group to the local Administrators group on the
witness server. These security permissions are necessary to ensure that Exchange can create a
directory and share on the witness server as needed.

The answer is wrong – This is correct
1 – Add the Exch Trusted Sub to local admin on server 1 – The Ex Trusted Subsytem includes all Exchange server and allows them to check the file share whitness)
2 – Create a DAG and set Server 1 a FSW
3 – Add EX1 and EX2 to DAG
•No need to install Exch on Server 1 as it is a file share witness. This can be any server in the environment (non-DC preferred).
•DAG will never auto select file share witness. It won’t just randomly pick a server in your environment.
I agree with BigHaig
I just lack to understand why they don’t even mention Server1 in the question…
I dont agree, the question does not mention that “Server1” is already installed, so my answer is:
1) Install Exchange Server 2013 on Server1 (This will add the Exchange Trusted Group to local admin)
2) Create DAG and Specify Server1 as the file share witness.
3) Add EX1 and EX2 to DAG.
Question its self said, servers are already installed. Then why we need to install the Exchange again.
