CompTIA Security+ (SY0-501) — Question 335

Which of the following is the summary of loss for a given year?

Answer options

• A. MTBF
• B. ALE
• C. SLA
• D. ARO

Correct answer: B

Explanation

The correct answer is ALE (Annualized Loss Expectancy), which quantifies the expected yearly loss due to risks. MTBF (Mean Time Between Failures) measures reliability, SLA (Service Level Agreement) outlines service expectations, and ARO (Annual Rate of Occurrence) estimates how often a risk may occur, but none provide a summary of loss like ALE does.
