CompTIA A+ Core 2 (220-1102) — Question 268

A company-owned mobile device is displaying a high number of ads, receiving data-usage limit notifications, and experiencing slow response. After checking the device, a technician notices the device has been jailbroken. Which of the following should the technician do next?

Answer options

• A. Run an antivirus and enable encryption
• B. Restore the defaults and reimage the corporate OS
• C. Back up the files and do a system restore
• D. Undo the jailbreak and enable an antivirus

Correct answer: B

Explanation

The correct action is to restore the defaults and reimage the corporate OS (Option B) because this will eliminate any unauthorized modifications and return the device to a secure state. Running an antivirus (Option A) may not fully address the jailbreaking issue, while backing up files (Option C) or undoing the jailbreak (Option D) does not guarantee complete restoration of the device's security and functionality.
