0How is SLE calculated?
Answer Options
A
AV * EF
B
RTO * AV
C
MTTR * EF
D
AV * ARO
Correct Answer: A
Explanation
The single loss expectancy (SLE) describes what a single risk event is likely to cost. It is calculated using the asset value (AV) times the exposure factor (EF), which is an estimated percentage of the cost that will occur in damage if the loss occurs. MTTR is the mean time to repair, ARO is the annual rate of occurrence, and RTO is the recovery time objective. These are not part of the SLE equation.
