Click on the arrows to vote for the correct answer
A. B. C. D. E.D.
Based on the given scenario, the issue seems to be related to the standby time of an iOS mobile device after a new update. The technician has verified that no new applications were installed since the update, but the issue persists even after the update is removed.
A. Zero-day malware: Zero-day malware refers to malicious software that exploits a previously unknown vulnerability in a computer system or software. While malware can cause various issues, it is less likely to be the cause of the standby time issue described in the scenario.
B. Safari code injection: Safari code injection refers to a type of attack where malicious code is injected into a website viewed through the Safari web browser on an iOS device. While this type of attack can cause issues, it is unlikely to be the cause of the standby time issue described in the scenario.
C. OS corruption: OS corruption refers to a situation where the operating system of a device becomes damaged or unusable. This can cause various issues, including poor performance and battery life. Therefore, it is possible that OS corruption could be the cause of the standby time issue described in the scenario.
D. Overheating: Overheating occurs when a device's temperature rises to a level that can cause damage or reduce performance. Overheating can cause battery drain and reduced standby time, so it is possible that this could be the cause of the issue described in the scenario.
E. Time sync failure: Time sync failure refers to a situation where a device's clock is not synchronized with an accurate time source. While this can cause various issues, it is unlikely to be the cause of the standby time issue described in the scenario.
Given the information provided, the most likely cause of the issue is C. OS corruption or D. Overheating. However, further troubleshooting is required to determine the exact cause of the standby time issue.
