Certified Information Systems Auditor (CISA) — Question 212

Which of the following is the MOST important environmental equipment that should be located above the false ceiling of a data center?

Answer options

• A. Air pressure sensors
• B. Motion detectors
• C. Smoke detectors
• D. Humidity sensors

Correct answer: C

Explanation

Smoke detectors are essential for fire safety in a data center, making them the most important equipment to place above the false ceiling. While air pressure sensors, motion detectors, and humidity sensors provide useful environmental monitoring, they do not address the immediate danger posed by smoke and fire, which can have catastrophic consequences.
