SK0-003 · Question #516
Which of the following is MOST likely to occur if the temperature in the server room is cooled too quickly after a power outage?
The correct answer is A. Server forms condensation. Rapid cooling of warm server components, especially in high humidity, can cause condensation to form on surfaces. This poses a significant risk of electrical shorts and hardware damage.

Why each option
Rapid cooling of warm server components, especially in high humidity, can cause condensation to form on surfaces. This poses a significant risk of electrical shorts and hardware damage.
When warm server components are exposed to rapidly cooled air, particularly if the air has high humidity, the temperature of the components can drop below the dew point. This causes water vapor to condense on their surfaces, which can short-circuit electronic components and cause severe hardware damage.
While condensation can damage components and prevent a server from POSTing later, the immediate and most likely physical phenomenon occurring directly from rapid cooling is the formation of condensation, not an immediate failure to POST.
Services not starting is a software or operating system issue that occurs after a successful boot and is not a direct consequence of rapid temperature change causing physical condensation.
Slow server response times are typically associated with performance bottlenecks, hardware issues, or high loads, not directly with temperature changes themselves, though extreme temperatures can lead to thermal throttling or component failure.
