A company is upgrading its 3,000 client computers to Office 365 ProPlus. The company uses the Telemetry
Dashboard to identify document compatibility issues. The Telemetry Agent is deployed to all client computers.
The telemetry environment is described in the following table.

You need to ensure that telemetry data is collected for more than 20 client computers at a time.
What should you do?

A.
Migrate the telemetry database to a computer that runs SQL Server 2008.

B.
Use the Registry Editor to trigger the data collection.

C.
Use Group Policy to set the MaxConnectionsPerServer setting to 100.

D.
Migrate the Telemetry Processor to a computer that runs Windows Server 2012.

Explanation:
Test or small production environments support computers running Windows 7, Windows 8, and Windows 8.1.
These environments are, however, limited of 20 concurrent connections for client operating systems. You,
therefore, have to migrate the Telemetry Processor to a computer that supports a larger production
environment. Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server
2012 R2 are operating systems that are recommended for this type of environment.
