The correct answer is B. A power surge occurred. The precise timing overlap between the cleaning crew starting their shift and the unexpected server shutdown points to a power surge from the crew's electrical equipment as the most likely cause.
Question

Options
- AA hard disk on the server failed.
- BA power surge occurred.
- CThe CPU on the server overheated.
- DA memory module on the server failed.

Why each option
The precise timing overlap between the cleaning crew starting their shift and the unexpected server shutdown points to a power surge from the crew's electrical equipment as the most likely cause.
A hard disk failure causes I/O errors or degraded array status but does not typically trigger an immediate, clean shutdown of the entire server.
Cleaning crews use high-draw appliances such as vacuums and floor scrubbers that can cause power surges or momentary outages on circuits shared with server equipment. A power surge can force an unplanned server shutdown instantly, and the strong temporal correlation with the crew starting work makes an electrical disturbance the most logical explanation.
CPU overheating is a gradual process driven by sustained workload, not an event that suddenly occurs the moment external personnel begin their shift.
Memory module failures produce system errors or crashes over time and are not correlated with environmental events such as a cleaning crew starting work.
