220-1102 Practice Question: During a software deployment, a technician needs…
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?
⚠ Common exam trap
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.'

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.
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.
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
Enabling a pop-up blocker is designed to prevent unsolicited new browser windows or tabs from automatically opening, typically for advertising or intrusive content. While it enhances user experience by reducing distractions, it offers no mechanism for isolating an application's process from the underlying operating system or other browser components. Therefore, it does not provide the security isolation required for sandboxing during a software deployment.
- ✗
Enable private browsing mode.
Why it's wrong here
Enabling private browsing mode, often called incognito mode, primarily focuses on user privacy by preventing the browser from storing local data such as browsing history, cookies, cache, and form data on the device. This mode ensures that no traces of the browsing session remain after the window is closed. However, it does not create a secure, isolated environment that restricts the web application's access to system resources or prevents interaction with other processes, which is the core function of sandboxing.
- ✓
Enable browser sandboxing.
Why this is correct
Enabling browser sandboxing is the correct approach because it creates a highly controlled and isolated environment for web applications or specific browser processes. This isolation mechanism restricts the application's access to critical system resources, such as the file system, network interfaces, and memory outside its designated space. By confining the application, sandboxing prevents potential malicious code from affecting the host operating system or other browser tabs, thereby ensuring secure software deployment.
- ✗
Disable JavaScript.
Why it's wrong here
Disabling JavaScript prevents client-side scripts from executing within a web browser, which can reduce certain attack vectors by eliminating dynamic content and potential script-based vulnerabilities. However, this action does not establish a secure, isolated container for the entire web application process itself. While it might prevent some forms of malicious activity, it fails to provide the comprehensive process isolation and resource restriction that defines true sandboxing for secure software deployment.
