Certified Information Systems Auditor (CISA) — Question 867

Where should photoelectric smoke detectors be installed to improve fire detection at an offsite data processing facility?

Answer options

• A. Entry points
• B. Air vents
• C. Server cages
• D. Exit points

Correct answer: C

Explanation

Installing photoelectric smoke detectors in server cages is crucial because these areas house critical equipment that can easily overheat and catch fire. Entry points and exit points are not effective since they do not monitor the areas where fires are most likely to start. Air vents might distribute smoke but do not provide adequate coverage for fire detection in high-risk zones.
