Free CISSP Certification Practice Questions:
Which formula can be used to calculate the Annualized Loss Expectancy (ALE)?
A) SLE (Single Loss Expectancy) + ARO (Annualized Rate of Occurrence)
B) Asset Value * EF (Exposure Factor)
C) Asset Value * EF (Exposure Factor) * ARO (Annualized Rate of Occurrence)
D) SLE (Single Loss Expectancy) * ARO (Annualized Rate of Occurrence) * Asset Value
-
[Ans: C]
The ALE (Annualized Loss Expectancy) is
calculated as follows:
SLE (Single Loss
Expectancy) * ARO (Annualized Rate of Occurrence).
The SLE (Single Loss Expectancy) is calculated
as follows: Asset Value * EF (Exposure Factor)
Hence, ALE can also be calculated as follows: Asset Value * EF (Exposure Factor) * ARO (Annualized Rate of Occurrence).
