Certified Information Systems Auditor (CISA) — Question 494

The PRIMARY benefit to using a dry-pipe fire-suppression system rather than a wet-pipe system is that a dry-pipe system:

Answer options

• A. disperses dry chemical suppressants exclusively.
• B. has a decreased risk of leakage.
• C. allows more time to abort release of the suppressant.
• D. is more effective at suppressing flames.

Correct answer: B

Explanation

The correct answer is B because a dry-pipe system contains pressurized air in the pipes, reducing the chance of water leakage compared to a wet-pipe system, which is filled with water. Options A, C, and D do not accurately describe the primary benefit of dry-pipe systems, as they focus on aspects that do not define the essential advantage of reduced leakage risk.
