220-1102 Question #731: Real Exam Question with Answer & Explanation

Question

Which of the following environmental controls is most important to maintain the safety of a data center?

Options

• ATemperature control
• BHumidity control
• CFire suppression control
• DPower management control

Explanation

While all environmental controls are important, fire suppression control is the most critical for maintaining data center safety because a fire can cause catastrophic damage, complete data loss, and pose an immediate danger to personnel.

Common mistakes.

• A. Temperature control is crucial for equipment longevity and performance, but a sudden temperature spike is less immediately catastrophic to safety than an uncontrolled fire.
• B. Humidity control prevents static discharge and corrosion, important for equipment health, but uncontrolled humidity is not as immediate or catastrophic a safety hazard as a fire.
• D. Power management control ensures continuous operation and protects against power surges, but a power failure or surge does not typically pose the same immediate threat to physical safety or complete destruction as a fire.
