What term refers to any event that is not part of the ordinary operation of a service that causes, or may cause, an interruption to, or a reduction in, the quality of that service?

• A. Event
• B. Frequency
• C. Exploit
• D. Incident

Answer: (D)

An incident is any event that is not part of the normal operation of a service and that causes, or could cause, an interruption to, or a reduction in, the quality of that service. This captures both actual disruptions and situations that could lead to disruption, making it central to incident management which aims to restore service quickly and minimize impact. A routine event that doesn’t affect service isn’t considered an incident. An exploit is a method attackers use to take advantage of a vulnerability, not the disruption itself. Frequency is just a measure, not a type of disruptive event. So the term that best fits the description is incident.
