organization have Exchange Server 2010 Service Pack 1 (SP1) installed.
You need to retrieve the following information for the organization:
The IP addresses of all client connections
The network latency for all MAPI connections
The version of Microsoft Outlook that is used to access all of the mailboxes
What should you use?

A.
the Microsoft Exchange Server User Monitor (ExMon)

B.
the Test-LogonStatistics cmdlet

C.
the Test-MAPIConnectivity cmdlet

D.
the Remote Connectivity Analyzer

Explanation:
Use the Microsoft Exchange Server User Monitor to gather real-time data to better
understand current client usage patterns, and to plan for future work. Administrators can
view several items, including IP addresses used by clients, versions and modes of Microsoft
Office Outlook, and resources such as CPU usage, server-side processor latency, and total
latency for network and processing. Works with Microsoft Exchange Server 2000, 2003,
2007 and 2010.
