Certified Information Systems Auditor (CISA) — Question 716

Which of the following is the MOST appropriate and effective fire suppression method for an unstaffed computer room?

Answer options

• A. Water sprinkler
• B. Fire extinguishers
• C. Carbon dioxide (CO )
• D. Dry pipe

Correct answer: C

Explanation

Carbon dioxide (CO2) is the most appropriate fire suppression method for an unstaffed computer room as it effectively extinguishes fires without causing damage to electronic equipment. Water sprinklers and fire extinguishers can cause water damage or require human intervention, making them less suitable for unattended spaces. Dry pipe systems may not be as effective in quickly suppressing a fire in sensitive environments.
