A user attempts to install a new and relatively unknown software program recommended by a colleague.
The user is unable to install the program, dispute having successfully installed other programs previously.
Which of the following is MOST likely the cause for the user’s inability to complete the installation?

A.
Application black listing
B.
Network Intrusion Prevention System
C.
Group Policy
D.
Application White Listing
This is incorrect. The answer should be D. If the software is “new and relatively unknown,” there would be no reason to blacklist it. Only a whitelist would block installation of unknown software. The answer is therefore Application White Listing.

The reason he was “unable to install the program” because the application is on black list.

The correct answer is whitelisting. This is a new and unknown program–it would not be on the blacklist. Since it is not on the whitelist, people cannot install it on the system. D is the correct answer.
