Which of the following metrics are used to calculate the SLE? (Select TWO)

ROI (Return on Investment) is a financial metric for evaluating the profitability of an investment and is not used in SLE calculation.

ARO (Annualized Rate of Occurrence) represents the expected frequency of a threat's occurrence in a year, and it serves as the divisor for ALE when calculating SLE (SLE = ALE / ARO).

ALE (Annualized Loss Expectancy) is the total estimated financial loss from a specific risk over a year; when ALE is divided by ARO, it directly yields the SLE (SLE = ALE / ARO).

MTBF (Mean Time Between Failures) is a reliability metric indicating the average time an asset operates before failing, unrelated to SLE.

MTTF (Mean Time To Failure) is a reliability metric representing the average time an asset is expected to function before permanent failure, not used for SLE.

TCO (Total Cost of Ownership) is a comprehensive financial estimate of all direct and indirect costs associated with an asset, not directly used in SLE calculation.
