You are the systems administrator for your company. You install Windows Essential Business Server 2008 on the network. Several users on the network use mobile devices to access the Messaging Server. You want to create a new Exchange ActiveSync mailbox policy to require password for all mobile devices. You want to use the Set-ActiveSyncMailboxPolicy cmdlet for this purpose.

What is the minimum Exchange administrator role you will require?

A.
the Exchange Organization Administrators role

B.
the Exchange Recipient Administrators role

C.
the Exchange Server Administrators role

D.
the Exchange Public Folder Administrators role

Explanation:
You will require the Exchange Organization Administrators role. The Set-ActiveSyncMailboxPolicy cmdlet enables you to apply a variety of mailbox policy settings to a server. Exchange ActiveSync mailbox policies are used to apply a common set of policies or security settings to a collection of users. By using Exchange ActiveSync mailbox policies, you can require a password for mobile devices, specify the minimum password length, and require a number or special character in the password. You can use the New Exchange ActiveSync Mailbox Policy wizard or the Set-ActiveSyncMailboxPolicy cmdlet to create an ActiveSync mailbox policy. To run the Set-ActiveSyncMailboxPolicy cmdlet, you must use an account that is delegated the Exchange Organization Administrators role.

All other options are incorrect because the account you use to create a new Exchange ActiveSync mailbox policy must be delegated the Exchange Organization Administrators role. The Exchange Organization Administrators role gives administrators full access to all Exchange properties and objects in the Exchange organization. The Exchange Recipient Administrators role has permissions to modify any Exchange property on an Active Directory user, contact, group, dynamic distribution list, or public folder object. The Exchange Server Administrators role provides its members permissions to administer a particular Exchange server, but does not grant permissions to perform operations that have global impact in the Exchange organization. The Exchange Public Folder Administrators role provides its members the required administrative permissions to manage all public folders.
