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:

Telemetry Processor runs on one or more computers and collects inventory, usage, and telemetric data from the telemetry shared folder and imports the data to the
telemetry database. Telemetry Processor is installed as a Windows service named “Telemetry Processor.”
We recommend the following operating systems for computers that run Telemetry Processor:
For production environments for best performance, we recommend these operating systems:
Windows Server 2008
Windows Server 2008 R2
Windows Server 2012
Windows Server 2012 R2
For test or small production environments You can use computers that run Windows 7, Windows 8, and Windows 8.1 in test environments and in small production
environments. There is a limit of 20 concurrent connections for client operating systems, but in small environments, the agent randomization setting should
minimize any chances of more than 20 agents connecting at one time.
