Your network contains a System Center 2012 R2 Configuration Manager Service Pack 1 (SP1)
environment.
You are creating a configuration item that contains application settings for Microsoft Office 2013.
You need to detect whether Office 2013 is installed before validating the configuration item.

What should you do?

A.
Set Software Inventory to True.

B.
Create a report to display all installed software.

C.
Set Hardware Inventory to False.

D.
Enable Use a custom script to detect this application.

Explanation:
A detection method in Configuration Manager contains rules that check whether an application is
already installed on a device. This detection occurs before the application is installed, immediately
after the application is installed, and at regular intervals afterward. This detection can prevent
Configuration Manager from needlessly reinstalling the application and can also determine whether
the user has already uninstalled the application. A custom script can be used to determine the
presence of a deployment type.
Note: A System Center 2012 Configuration Manager application contains the files and information
that are required to deploy software to a device. An application contains one or more deployment
types that comprise the installation files and information that are required to install software. A
deployment type also contains rules that specify when and how the software is deployed.
