ALE Question for Final Exam Q9-Q25: Metro Bank has an asset valued at $400,000, with an Exposure Factor (EF) of 80%. Its Annualized Rate of Occurrence (ARO) is 50%, resulting in an Annualized Loss Expectancy (ALE) of $160,000 as the base case. Currently, Metro Bank is evaluating two countermeasures with the same Annualized Countermeasure Cost of $40,000 but using different approaches: Countermeasure A will reduce ARO down to 20%, while keeping EF the same. Countermeasure B will reduce EF down to 10%, while keeping ARO the same.
