Why each option

This question requires calculating the Annualized Loss Expectancy (ALE) based on a given Single Loss Expectancy (SLE) and Annualized Rate of Occurrence (ARO).

A$2,000

$2,000 is an incorrect calculation and does not result from the given SLE and ARO values.

B$2,500Correct

The Annualized Loss Expectancy (ALE) is calculated by multiplying the Single Loss Expectancy (SLE) by the Annualized Rate of Occurrence (ARO). Given an SLE of $250,000 and an ARO of 0.01, ALE = $250,000 * 0.01 = $2,500.

C$3,510

$3,510 is an incorrect calculation and does not result from the given SLE and ARO values.

D$3,500

$3,500 is an incorrect calculation and does not result from the given SLE and ARO values.
