Exam SY0-601 topic 1 question 259 discussion

ARO - annualized rate of occurrence is a representation of the frequency of the event, measured in a standard year. In our case number of the defecive device per year. Annual loss expectancy (ALE) is the loss (amount of money) due ARO. The question is about the number of the device, not about money.

Option B, Annualized Rate of Occurrence (ARO), BEST describes the estimated number of devices to be replaced next year. ARO is the expected frequency of an event occurring over a given period of time based on historical data. In this case, the historical data shows a steady increase in the number of devices replaced due to loss, damage, or theft. Assuming this trend continues, the ARO can be used to estimate the number of devices that will need to be replaced next year. Option A, Annual Loss Expectancy (ALE), is the expected monetary loss per year due to a risk. This would not be the most appropriate measure for estimating the number of mobile devices to be replaced. Option C, Recovery Point Objective (RPO), is the maximum amount of data loss an organization can tolerate in the event of a disruption. This is not relevant to estimating the number of mobile devices to be replaced. Option D, Single Loss Expectancy (SLE), is the expected monetary loss from a single occurrence of a risk. This would not be the most appropriate measure for estimating the number of mobile devices to be replaced.

The ARO indicates how many times the loss will occur in a year. If the ARO is less than 1, the ARO is represented as a percentage. For example, if you anticipate the occurrence once every two years, the ARO is 50 percent or .5.

I initially thought the answer to this question was was (A) ALE until I watched Professor Messer's SYO-601 Risk Analysis video content. I would suggest watching it. Answer's (B) ARO....

so many abbreviations

So many abbreviation man, my brain might explode at some point

ALE - Annual Loss Expectancy which is the expected monetary loss for an asset due to a particular risk over a single year. The calculation is ARO * SLE = ALE

Answer B. ARO

ARO just tells how often it occurs, it does not tell you how many devices. So it could happen 12 times (once a month) but does not mean 12 devices, as each instance may vary. SLE tells how much 1 instance costs but this doesn't give you the whole picture. It is clearly ALE since it mentions last 5 years (annually it is up, 10% since 5 years ago) ALE is best because you know the cost of devices and divide the cost by the annual loss expected (if $1200 lost a year and devices are $50 then 24 devices, but using 12 as ARO does not tell you if 12 were lost, 24 or more)

Annualized Loss Exposure (ALE), sometimes referred to as annualized loss expectancy, is the most recognized and relevant figure businesses can pull from quantitative analysis... ALE talks about QUANTITY. ARO is how often.

estimated number of devices to be replaced next year sounds like annyal loss expectancy.... they are already expecting this.... so they want an estimate on how many devices to be replaced next year... ALE all day long they do not talk about the rate, they already know the rate, they are already expecting this loss

In the context of risk management and incident response, ARO stands for Annualized Rate of Occurrence. It represents the estimated frequency or likelihood of a particular event occurring in a given year. In this case, the IT manager is estimating the number of mobile devices that are expected to be replaced due to loss, damage, or theft next year. Given that the number of devices replaced due to loss, damage, or theft has steadily increased by 10% over the last five years, the ARO would be used to estimate the expected number of replacements for the upcoming year. The ARO takes into account historical data to project future occurrences of the event.

You are right. In the context of a CompTIA exam, the more straightforward answer for Question #259 would be: B. ARO Explanation: The Annual Rate of Occurrence (ARO) would best describe the estimated number of devices to be replaced next year. ARO represents the expected frequency of a specific event or risk occurring within a year. In this case, the steady increase in the number of devices replaced due to loss, damage, or theft can be estimated using the ARO. ^ you guys really gotta work on your prompts (and use GPT-4) if you want to paste ChatGPT answers as solutions

I think D.SLE is much more relevant answer. https://learn.saylor.org/mod/book/view.php?id=29692&chapterid=5327

Annual Loss Expectancy (ALE) is a measure of the estimated financial loss that an organization can expect to incur over a given period of time. In this scenario, the IT manager is trying to estimate the number of devices that will need to be replaced next year due to loss, damage, or theft. The IT manager is aware that the number of devices that were replaced over the last five years has steadily increased by 10%. To estimate the number of devices that will need to be replaced next year, the IT manager would use the ALE formula: ALE = SLE x ARO.

B is the Answer
