CompTIA Security+ (SY0-501) — Question 848

Which of the following metrics are used to calculate the SLE? (Choose two.)

Answer options

• A. ROI
• B. ARO
• C. ALE
• D. MTBF
• E. MTTF
• F. TCO

Correct answer: B, C

Explanation

The correct answers are B (ARO) and C (ALE) because the Single Loss Expectancy (SLE) is calculated using the Annual Rate of Occurrence (ARO) and the Average Loss Expectancy (ALE). The other options like ROI, MTBF, MTTF, and TCO do not directly contribute to calculating SLE.
