CompTIA Security+ (SY0-601) — Question 108

An IT manager is estimating the mobile device budget for the upcoming year. Over the last five years, the number of devices that were replaced due to loss, damage, or theft steadily increased by 10%. Which of the following would BEST describe the estimated number of devices to be replaced next year?

Answer options

• A. ALE
• B. ARO
• C. RPO
• D. SLE

Correct answer: B

Explanation

The correct answer is ARO (Annual Rate of Occurrence), which quantifies the expected frequency of an event occurring within a year, in this case, device replacements. ALE (Annual Loss Expectancy) refers to the expected monetary loss per year, RPO (Recovery Point Objective) relates to data recovery, and SLE (Single Loss Expectancy) pertains to the monetary loss from a single incident, making them less relevant for estimating device replacements.
