- A
Enable pop-up blocker.
Why wrong: Pop-up blocker only prevents unwanted pop-up windows, not sandboxing of applications.
- B
Enable private browsing mode.
Why wrong: Private browsing prevents history and cookie storage but does not provide sandboxing from system resources.
- C
Enable browser sandboxing.
Sandboxing isolates the web application process, preventing it from accessing the system or other tabs, which is exactly what is needed.
- D
Disable JavaScript.
Why wrong: Disabling JavaScript might break many web apps, but it does not provide sandboxing.
Question 535 of 750
How Browser Sandboxing Enhances Security
This 220-1202 practice question tests your understanding of browser and application security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
During a software deployment, a technician needs to ensure that a new web application can run in a sandboxed environment to prevent it from accessing other system resources. Which browser feature should be configured?
Quick Answer
The correct answer is to enable browser sandboxing. This security feature works by isolating each open tab or web application into its own restricted environment, preventing malicious code from accessing the operating system, other tabs, or system resources. On the CompTIA A+ Core 2 220-1202 exam, this concept often appears in scenario-based questions about software deployment or secure browsing, testing your understanding of how browser sandboxing enhances security by containing threats. A common trap is confusing sandboxing with private browsing or pop-up blockers—remember that sandboxing is about process isolation, not privacy. For the exam, think of it as a "digital quarantine": each tab runs in its own cage, so if one gets infected, the rest of the system stays safe. A helpful memory tip is "Sandbox stops the box from being popped"—the sandbox prevents the browser from breaking out of its secure container.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable browser sandboxing.
Option C is correct because browser sandboxing is a security mechanism that isolates the web application's processes from the rest of the system, preventing it from accessing other system resources such as the file system, registry, or other processes. This is commonly implemented in modern browsers (e.g., Chrome's multi-process architecture with a sandbox layer) to contain potential exploits from a compromised web application.
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.
- ✗
Enable pop-up blocker.
Why it's wrong here
Pop-up blocker only prevents unwanted pop-up windows, not sandboxing of applications.
- ✗
Enable private browsing mode.
Why it's wrong here
Private browsing prevents history and cookie storage but does not provide sandboxing from system resources.
- ✓
Enable browser sandboxing.
Why this is correct
Sandboxing isolates the web application process, preventing it from accessing the system or other tabs, which is exactly what is needed.

Why it's wrong here
Disabling JavaScript might break many web apps, but it does not provide sandboxing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between privacy features (like private browsing) and security features (like sandboxing), leading candidates to confuse 'preventing local storage of data' with 'preventing system resource access.'
Detailed technical explanation
How to think about this question
Browser sandboxing typically leverages operating system-level mechanisms such as Windows Job Objects, Linux namespaces (e.g., PID, network, mount), or macOS Seatbelt profiles to restrict the child process's capabilities. For example, Chrome's sandbox uses a restricted token on Windows that denies access to most system objects, and the renderer process runs in a separate integrity level (Low Integrity) to prevent write access to higher-integrity processes. This ensures that even if an attacker exploits a vulnerability in the web application, they cannot escape the sandbox to execute arbitrary code on the host.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- 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.
