Exam FC0-U61 topic 1 question 469 discussion

A. Mobile phone Explanation: A mobile phone connected via USB can charge and even access the system briefly before being unplugged. Since the device is never present when the technician checks, it is likely a mobile phone that an employee plugs in during work hours and removes before leaving. Mouse (B) and Scanner (C) are unlikely because they are usually permanently connected and wouldn't trigger intermittent log entries. External hard drive (D) could be a possibility, but file audits revealed no unexpected changes, making it less likely.

Mobile phones can be connected to workstations via USB to charge or transfer data. They are often plugged in and unplugged frequently throughout the day, and may not be present when the technician checks the machine. Since file audits reveal nothing unexpected, it suggests that the device is not being used for malicious purposes, which aligns with the behavior of a mobile phone being connected for charging or occasional data transfer.
