ISC2 ISSAP Exam - Topic 4 Question 34 Discussion

Actual exam question for ISC2's ISSAP exam
Question #: 34
Topic #: 4
[All ISSAP Questions]

Single Loss Expectancy (SLE) represents an organization's loss from a single threat. Which of the following formulas best describes the Single Loss Expectancy (SLE)?

Show Suggested Answer Hide Answer
Suggested Answer: A

the occurrence of a risk on an asset. It is mathematically expressed as follows:

Single Loss Expectancy (SLE) = Asset Value (AV) * Exposure Factor (EF)

where the Exposure Factor is represented in the impact of the risk over the asset, or percentage of asset lost. As an example, if the Asset

Value is reduced two thirds, the exposure factor value is .66. If the asset is completely lost, the Exposure Factor is 1.0. The result is a

monetary value in the same unit as the Single Loss Expectancy is expressed.

Answer options D, B, and C are incorrect. These are not valid formulas of SLE.

I thought it was B at first, but A makes more sense.

It's definitely A, that's the standard formula.

I thought SLE was linked to the Annualized Rate of Occurrence, but that might be for a different calculation. I need to double-check my notes!

I feel a bit confused about the differences between SLE and ALE. I think SLE is related to the asset value, but I can't recall the exact formula.

I remember practicing a question like this, and I believe the correct answer is A. It makes sense to multiply the asset value by the exposure factor.

I think SLE is calculated using Asset Value and Exposure Factor, but I'm not entirely sure if it's the right formula.

Hmm, I'm a bit unsure about this one. I'll need to review my notes on server form factors to make sure I understand the difference between 1U, 2U, and other rack sizes before I can confidently answer this question.

Hmm, this is a tricky one. I'll need to think carefully about the criteria used to determine quality requirements relationships.

I'm a little confused by the options here. Reformatting the hard drive or deleting the partition seem like overkill. I'm going to go with the Disk Cleanup tool - that seems like the most efficient way to clear out those temporary files.
