Q

From a quantitative risk perspective, when will SLE and AV be equal?

A. When ARO is %100
B. When AV is 50%
C. When EF is 50%
D. When EF is 100%

A

D. When EF is 100%

Explanation:
AV (asset value) is how much an asset is worth

EF (Exposure factor) is how much a particularly threat could impact a given asset, expressed as a percentage

SLE (Single loss eexpectancy) is the amount of loss expected if an even occurs. The SLE formula is:

SLE = AV x EF

Therefore, SLE will equal AV when EF is 100% because the formula becomes:

SLE= AV x 1.00
