Your network contains a System Center 2012 Configuration Manager environment.
Software Inventory and Hardware Inventory are enabled for all client computers.
All of the client computers have an application named App1 installed. App1 saves files to the
C:\Program Files\App1 folder. All of the files saved by App1 have a file name extension of
.xyz.

You configure Software Inventory to inventory all of the files that have the .xyz extension and
the .exe extension.
After six months, you discover that some of the client computers fail to inventory .xyz files.
All of the client computers inventory .exe files.
You need to ensure that the .xyz files are inventoried.
What should you do?

A.
Modify C:\Program Files\App1 \Skpswi.dat.

B.
Modify C:\NO_SMS_On_Drive.sms.

C.
Delete C:\Program Files\App1 \Skpswi.dat.

D.
Delete C:\NO_SMS_On_Drive.sms.

Explanation:

The hidden file Skpswi.dat is used by Configuration Manager administrators to avoid the
overhead of running software inventory on large disk drives. When it is placed in the root of
each folder that must be excluded from Configuration Manager software inventory, software
inventory will not report any inventory data for that drive.
