The correct answer is Windows Defender Application Guard. This security feature is most likely causing the issue because it uses hardware-based isolation to run untrusted applications in a secure container, and a Windows update can alter its default policies or behavior, triggering the “Your IT department has limited access” message for legacy apps that previously ran without restriction. On the CompTIA A+ Core 2 220-1202 exam, this question tests your ability to distinguish Application Guard from Windows Sandbox—a common trap is confusing the two, since both use containers, but Application Guard is specifically designed for enterprise-managed devices and blocks apps from accessing local resources like the file system or camera. A helpful memory tip: think of Application Guard as a “bouncer for legacy apps” that gets stricter after updates, while Sandbox is a disposable test environment you launch manually.
220-1102 Windows Security Settings Practice Question
This 220-1202 practice question tests your understanding of windows security settings. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user reports that their Windows 10 computer is displaying a 'Your IT department has limited access to some features of this app' message when trying to run a legacy application. The application worked before the latest Windows update. Which security feature is most likely causing this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: Firewall rules block network traffic, not application features, and would not display this specific message.
B
Windows Defender Application Guard
Application Guard uses container technology to isolate untrusted apps, and the message is typical when an app tries to access resources outside the container.
C
User Account Control (UAC)
Why wrong: UAC prompts for elevation but does not display a message about limited access to app features.
D
BitLocker Drive Encryption
Why wrong: BitLocker encrypts the drive and does not affect application functionality directly.
