The correct answer is User Account Control (UAC) because it is the Windows security feature specifically designed to prevent unauthorized system changes by requiring explicit permission before allowing modifications to protected system settings. When a user installs software that attempts to alter network configurations or other critical system areas, UAC triggers a prompt asking for administrator approval; if the user denies this prompt, the application is blocked from making those changes, thereby safeguarding system integrity. On the CompTIA A+ Core 2 220-1202 exam, this concept tests your understanding of how UAC acts as a gatekeeper against privilege escalation and unauthorized configuration changes—a common trap is confusing UAC with antivirus software or Windows Defender Firewall, but remember that UAC focuses on permission prompts, not malware scanning. A useful memory tip: think of UAC as the “ask first” guard—if a program tries to change something without asking, UAC steps in to stop it.
220-1202 Logical Security Concepts Practice Question
This 220-1202 practice question tests your understanding of logical security concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 they can no longer access the internet after installing a new software application. The technician suspects the application modified system settings. Which security feature could have prevented this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
User Account Control (UAC)
User Account Control (UAC) prompts for permission before allowing changes that affect system settings. If the user had denied the UAC prompt, the application would not have been able to modify network settings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Windows Defender Firewall
Why it's wrong here
Windows Defender Firewall controls inbound/outbound traffic but does not prevent software from changing system settings.
✓
User Account Control (UAC)
Why this is correct
UAC prompts for administrator approval before system changes, which could have blocked the application from modifying settings.

✗
BitLocker Drive Encryption
Why it's wrong here
BitLocker encrypts the drive but does not prevent software from making system changes.
✗
Windows Defender Antivirus
Why it's wrong here
Antivirus software detects malware but may not block legitimate applications from changing system settings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
