Which statement best defines a Major Malfunction?

• A. A nuisance alarm caused by weather
• B. A routine maintenance notification
• C. A failure that would allow an intruder to penetrate a restricted area boundary without crossing at least one line of detection.
• D. A false alarm due to lightning

Answer: (C)

Major Malfunction describes a serious failure in a security system that undermines its ability to detect or report an intrusion, creating a real vulnerability along the boundary. The option that fits this best describes a failure that would allow an intruder to penetrate a restricted area boundary without crossing at least one line of detection. That directly shows the system losing its protective function and missing a breach, which is the essence of a major malfunction. Nuisance alarms caused by weather, routine maintenance notifications, and false alarms due to lightning are not about a systemic loss of detection capability. They are interruptions or false signals, not a fundamental failure that creates a gap in the security boundary itself.
