A small business is considering placing a server in their warehouse. No one has accessed this warehouse for years. Which of the following considerations is of MOST concern?

ESD (Electrostatic Discharge) is a concern when handling components but is not a primary ongoing environmental concern for an operating server in an unaccessed warehouse.

While stable power is crucial, the question doesn't imply a power issue in the warehouse, and dust presents a more direct and probable environmental problem in an unaccessed space.

NTP (Network Time Protocol) ensures accurate time synchronization but is a network configuration issue, not an environmental or physical concern related to placing a server in a dusty warehouse.

Dust is a major concern in an old, unaccessed warehouse because it can accumulate rapidly on server components, blocking airflow, acting as an insulator, and causing overheating. Overheating can lead to reduced performance, component degradation, and eventual hardware failure, making it a critical environmental factor for server longevity in such a location.
