Certified Ethical Hacker (CEH v11) — Question 216

Which IOS jailbreaking technique patches the kernel during the device boot so that it becomes jailbroken after each successive reboot?

Answer options

• A. Tethered jailbreaking
• B. Semi-untethered jailbreaking
• C. Semi-tethered jailbreaking
• D. Untethered jailbreaking

Correct answer: D

Explanation

The correct answer is D, as untethered jailbreaking permanently patches the kernel, allowing the device to remain jailbroken after reboots without any additional steps. In contrast, tethered and semi-tethered methods require a computer or specific actions after a reboot to maintain jailbreak functionality, while semi-untethered offers some level of persistence but still relies on user intervention.
