The answer is that a jailbroken iPhone’s most direct security risk is the bypass of app sandbox restrictions. On a standard iOS device, each app runs in its own isolated sandbox, preventing it from accessing data stored by other apps. Jailbreaking removes these kernel-level protections, meaning a malicious or compromised app can read corporate email, contacts, or documents from any other app on the device. On the CompTIA A+ Core 2 220-1202 exam, this concept tests your understanding of mobile device security controls and the real-world dangers of privilege escalation. A common trap is focusing on customization or malware alone, but the core exam point is that sandbox bypass enables data leakage across apps, which is the primary corporate concern. To remember this, think of the sandbox as a locked filing cabinet: jailbreaking removes the locks, so every drawer is open to every user.
220-1202 Mobile OS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of mobile os features and tools. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 security audit, a technician discovers that an employee's company-issued iPhone has been jailbroken. The employee claims they only did it to customize the home screen. Which security risk is most directly associated with a jailbroken device in a corporate environment?
Why wrong: While jailbroken devices often cannot update normally, the most direct security risk is the loss of app sandboxing, not just update inability.
B
It voids the warranty.
Why wrong: Voiding warranty is a support issue, not a direct security risk to corporate data.
C
It bypasses app sandbox restrictions, potentially exposing corporate data.
Jailbreaking removes iOS security layers, including sandboxing, allowing malicious apps to access data from other apps, which is a severe data leakage risk.
D
The device will perform slower.
Why wrong: Performance degradation can occur but is not the primary security concern; data exposure is the critical risk.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It bypasses app sandbox restrictions, potentially exposing corporate data.
This question tests understanding of jailbreaking risks. The correct answer is that jailbreaking removes sandbox restrictions, allowing apps to access data from other apps, which can lead to data leakage. This is a primary concern for corporate devices handling sensitive information.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
