CompTIA A+ Core 2 (220-1002) — Question 38

A user calls a technician regarding an iOS mobile device that is having problems with standby time after a new update was applied. The technician verifies no new applications were installed since the update, but the device still has poor standby time even after the update is removed. Which of the following is the MOST likely cause of the issue?

Answer options

• A. Zero-day malware
• B. Safari code injection
• C. OS corruption
• D. Overheating
• E. Time sync failure

Correct answer: D

Explanation

The most likely cause of the poor standby time is overheating, as it can lead to increased power consumption and reduced battery efficiency. Zero-day malware, Safari code injection, and OS corruption are less probable in this scenario since there were no new applications installed and the update was reversed. Time sync failure is also unlikely to directly affect standby time in a significant way.
