CompTIA Security+ (SY0-501) — Question 865

To determine the ALE of a particular risk, which of the following must be calculated? (Choose two.)

Answer options

• A. ARO
• B. ROI
• C. RPO
• D. SLE
• E. RTO

Correct answer: A, D

Explanation

To calculate the ALE, you need to determine the Annual Rate of Occurrence (ARO) and the Single Loss Expectancy (SLE). The ARO provides the frequency of the risk occurring within a year, while the SLE represents the monetary loss from a single occurrence. The other options, ROI, RPO, and RTO, do not directly contribute to calculating ALE.
