A flood model shows that if the riverside 911 radio shed floods, 40% of the $200,000 equipment value would be destroyed. In quantitative risk terms, what does that 40% figure represent?
Select an answer to reveal the explanation.
Short Explanation
Exposure factor is the slice of the pie that gets ruined when the flood hits—not how often floods arrive and not how long repairs take. Forty percent means two-fifths of that shed's gear value is gone in that scenario.
Full Explanation
Exposure factor (EF) is the percentage of an asset's value expected to be lost if a specific threat materializes. Combined with asset value it yields single loss expectancy (SLE = AV × EF). ARO, appetite, and MTTR describe frequency, governance preference, and repair time—not the fraction of value lost in one event.
