You have a System Center 2012 R2 Configuration Manager deployment.
All users have client computers that run Windows 8.1.
The users log on to their client computer as standard users.
An application named App1 is deployed to the client computers by using System Center.
You need to recommend a solution to validate a registry key used by App1.
If the registry key has an incorrect value, the value must be changed.
The registry key must be validated every day.
The solution must generate a report on non-compliant computers.
What is the best approach to achieve the goal? More than one answer choice may achieve the goal. Select the BEST answer.

A.
Group Policy preferences

B.
A desired configuration baseline

C.
The Windows PowerShell Desired State Configuration (DSC) feature

D.
The Microsoft Baseline Security Analyzer (MBSA)

Explanation:
The question indicates that we HAVE System Center deployed so there is no need to fiddle around with Group Polcies that won’t really work properly.
Not A – Above reason.
Not C – We dont need to install the DSC Powershell Tools, we need to create a DSC baseline.
Not D – MBSA can analyze and report but NOT carry out actions (cannot change the value of the registry key).
B – A Desired State Configurtion can stipulate the required status of the registry key. DSC also provides a means for non-compliant machines to remidiate their
compliance.
