CompTIA Security+ (SY0-601) — Question 435

Which of the following can be used to calculate the total loss expected per year due to a threat targeting an asset?

Answer options

• A. EF x asset value
• B. ALE / SLE
• C. MTBF x impact
• D. SLE x ARO

Correct answer: D

Explanation

The correct answer, D (SLE x ARO), is the formula used to calculate the Annual Loss Expectancy (ALE) by multiplying the Single Loss Expectancy (SLE) by the Annual Rate of Occurrence (ARO). The other options do not provide a correct method for calculating expected annual losses related to threats targeting assets.
