Technicians working with servers hosted at the company's datacenter are increasingly complaining of electric shocks when touching metal items which have been linked to hard drive failures. Which of…

Decreasing room temperature primarily addresses heat management and cooling efficiency, not the buildup of static electricity.

Increasing the humidity in the room makes the air more conductive, allowing static electricity to dissipate more readily from surfaces and bodies, thereby preventing the buildup of charge that causes painful shocks and destructive electrostatic discharge (ESD) to sensitive components like hard drives.

Utilizing better hot/cold aisle configurations is a thermal management strategy aimed at improving cooling efficiency, not preventing electrostatic discharge.

Implementing EMI (Electromagnetic Interference) shielding protects against electromagnetic interference that can disrupt electronic signals, not the electrostatic discharge causing physical shocks and component failures.
