Question 440
Two divisions rate the same unencrypted backup issue as 'high' and 'medium' because their analysts use different likelihood descriptions. What improves comparability?
Explanation
Correct Answer
Consistent criteria and evidence make qualitative ratings comparable across organizational units. Recovery controls have to be tested against actual restore requirements and isolated from the same compromise path; possessing a backup is not evidence that a timely, usable restoration is possible. The case turns on their analysts use different likelihood descriptions; “Apply an agreed likelihood-impact rubric with documented assumptions” addresses that precise condition. “Average the words high and medium to obtain a precise monetary loss” is not equivalent because ordinal labels cannot be arithmetically converted into financial impact without a model.
Incorrect Answers
Ordinal labels cannot be arithmetically converted into financial impact without a model. Risk work separates frequency and loss estimates, risk tolerance, authorized treatment and documented residual exposure. In the reported situation, their analysts use different likelihood descriptions. The effective mechanism is “Apply an agreed likelihood-impact rubric with documented assumptions”: consistent criteria and evidence make qualitative ratings comparable across organizational units.
Headcount is not a defensible substitute for shared risk assessment criteria. The evidence is their analysts use different likelihood descriptions. Risk work separates frequency and loss estimates, risk tolerance, authorized treatment and documented residual exposure. By contrast, “Apply an agreed likelihood-impact rubric with documented assumptions” operates on the specific concern: consistent criteria and evidence make qualitative ratings comparable across organizational units.
Eliminating assumptions harms explainability without correcting inconsistent risk scales. Telemetry provides evidence and may trigger a response; it does not automatically deny a transaction or remediate its cause. Here the decisive fact is their analysts use different likelihood descriptions. “Apply an agreed likelihood-impact rubric with documented assumptions” matches that requirement because consistent criteria and evidence make qualitative ratings comparable across organizational units.
