What technique installs unauthorized smartphone software and enables new features?
A user would like to install software and features that are not available with a smartphone's default software. Which of the following would allow the user to install unauthorized software and enable new features?
Community Votes
100% of anonymous learners picked answer C. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The exam tests the distinction between jailbreaking/rooting and side loading: jailbreaking grants root-level access to enable new features, while side loading only installs apps outside official stores.
CompTIA Security+ SY0-701 mobile device security question: 'Jailbreaking' is the correct answer because it removes manufacturer restrictions, enabling unauthorized software and new features. Community consensus strongly favors C over side loading, citing features beyond app installation.
Choosing D 'Side loading' is the most common trap. Test takers focus on 'install unauthorized software' but miss 'enable new features,' which requires OS-level modification via jailbreaking.

Expert Analysis
Why the Answer Is Correct
Jailbreaking removes restrictions imposed by the smartphone manufacturer or operating system, granting the user root-level access. This access allows installation of unauthorized software and also enables new features, system modifications, and customization that default software would not permit. Community comments consistently highlight the phrase 'enable new features' as the deciding factor, since side loading alone does not provide that capability.
Why the Other Options Are Wrong
SQLi (A) and Cross-site scripting (B) are web-based attacks that target servers and browsers, not smartphone OS permissions, so they do not enable software installation or new features on a device. Side loading (D) does allow installing apps from unofficial sources, but it does not inherently grant deeper OS-level access or enable system features. As one commenter noted, you must jailbreak the phone first before you can sideload apps, making C the only option that fully satisfies both parts of the question.
Community Comment Notes
The overwhelming majority of comments answer C. Comment 1 originally thought D but changed to C because of 'enabling new features,' while comment 3 directly called out that keyword. Comment 2 correctly mentioned that Android equivalent is 'rooting,' reinforcing the concept of OS-level access. One commenter (6) chose D by focusing only on unauthorized installation, illustrating the common trap. Overall, the community consensus is that 'jailbreaking' is the best answer because it encompasses both installing unauthorized software and enabling new features.

Exam Strategy
Look for two-part questions: if the action includes both installing unauthorized software and enabling new features, it implies OS-level privilege escalation. Eliminate web attack options first, then compare side loading vs jailbreaking by asking 'does it only install apps or also unlock features?'
