ISC CISSP Practice Test 10
Question 90
A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment. A later change introduces this additional requirement: Management wants dollar-based comparison of a proposed safeguard across sites. Select THREE elements that together supply the initial control, objective evidence of effectiveness, and the changed-requirement response. (Select THREE.)
- Rank risks by which executive complained most recently.
- Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option.
- The analysis documents annualized loss estimates, uncertainty and sensitivity to outage duration.
- Establish a documented scoring method grounded in business impact, likelihood evidence and risk criteria.
- A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
- Estimate expected annual loss and reduction using defensible frequency and loss assumptions.
Explanation
Correct Answers
D:Correct — initial control. Common assessed exposure supports rational treatment and investment decisions.
E:Correct — observable control evidence. The relevant result is: A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates. This provides a completed control test rather than an implementation promise.
F:Correct — changed condition. Quantitative risk measures inform cost-benefit tradeoffs beyond ordinal scoring.
Incorrect Answers
A:Incorrect — it fails the original constraint. Executive attention alone is neither probability nor loss magnitude.
B:Incorrect — the measure Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option. addresses a different case: A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data.
C:Incorrect — this evidence applies to another case: A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data. The specified requirement here is A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment.
Question 91
A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment. A designer proposes: Rank risks by which executive complained most recently. What is the MOST significant security deficiency in this proposal?
- Nonoccurrence of a breach is not evidence that future loss fits tolerance.
- Executive attention alone is neither probability nor loss magnitude.
- Untracked acceptance cannot support oversight or detect changes in exposure.
- Quantitative risk measures inform cost-benefit tradeoffs beyond ordinal scoring.
Explanation
Correct Answer
B:Executive attention alone is neither probability nor loss magnitude. This is the direct weakness in the proposed action.
Incorrect Answers
A:This is an advantage of another design (Require documented residual-risk acceptance with an expiry, compensating controls and periodic re-evaluation.), not the particular flaw of Rank risks by which executive complained most recently.
C:This is a limitation elsewhere: A business owner asks to accept unpatched internet-facing service risk indefinitely because 'nothing has happened yet.' It does not explain the deficiency of the specified proposed approach.
D:This explains a later shift in requirements (Management wants dollar-based comparison of a proposed safeguard across sites.), not the failure of the current proposal.
Question 92
A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment. The organization has now implemented this response: Establish a documented scoring method grounded in business impact, likelihood evidence and risk criteria. Which observation would MOST directly demonstrate that the security objective was met?
- An approved change ticket for Establish a documented scoring method grounded in business impact, likelihood evidence and risk criteria. without a completed verification result.
- A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
- Dependency analysis demonstrates common provider failure paths and accountable mitigation owners.
- An approved treatment plan shows residual loss, owners and criteria for deployment acceptance.
Explanation
Correct Answer
B:A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates. This validates that common assessed exposure supports rational treatment and investment decisions.
Incorrect Answers
A:An approved change without an executed test cannot prove operating effectiveness. The needed evidence is A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
C:This demonstrates controls in another circumstance: A supplier merger causes the same outsourced identity service to support five formerly independent business units.
D:This other observation is relevant to: A healthcare cloud migration has significant residual availability risk that exceeds approved tolerance despite proposed controls.
Question 93
A previous security situation was: A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment. Now the requirement changes: Management wants dollar-based comparison of a proposed safeguard across sites. Which NEW action BEST answers the changed need?
- A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
- Estimate expected annual loss and reduction using defensible frequency and loss assumptions.
- Establish a documented scoring method grounded in business impact, likelihood evidence and risk criteria.
- Rank risks by which executive complained most recently.
Explanation
Correct Answer
B:Quantitative risk measures inform cost-benefit tradeoffs beyond ordinal scoring. The revised action is Estimate expected annual loss and reduction using defensible frequency and loss assumptions.
Incorrect Answers
A:This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
C:This is the appropriate response to the original situation: Common assessed exposure supports rational treatment and investment decisions. It does not directly meet the new condition.
D:This remains inappropriate: Executive attention alone is neither probability nor loss magnitude.
Question 94
A healthcare cloud migration has significant residual availability risk that exceeds approved tolerance despite proposed controls. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Seek additional treatment or a formally authorized risk decision before accepting residual exposure.
- Claim the vendor alone accepts all healthcare outage risk.
- Update risk assessment to distinguish transferred financial loss from remaining operational and reputational risk.
- Require documented residual-risk acceptance with an expiry, compensating controls and periodic re-evaluation.
Explanation
Correct Answer
A:Residual risk must be evaluated by the accountable business risk owner against tolerance. This directly addresses the stated situation.
Incorrect Answers
B:Outsourcing technology does not eliminate the customer's business risk ownership. The proposal would not be defensible for this case.
C:This is appropriate for a later condition (The organization purchases insurance that covers part of the possible financial impact.), but it does not directly resolve the initial need. Insurance can transfer some monetary consequences but not prevent an outage or remove accountability.
D:This response addresses a different condition: A business owner asks to accept unpatched internet-facing service risk indefinitely because 'nothing has happened yet.' The present case requires the measure described by Seek additional treatment or a formally authorized risk decision before accepting residual exposure.
Question 95
A healthcare cloud migration has significant residual availability risk that exceeds approved tolerance despite proposed controls. A designer proposes: Claim the vendor alone accepts all healthcare outage risk. What is the MOST significant security deficiency in this proposal?
- Outsourcing technology does not eliminate the customer's business risk ownership.
- Ignoring concentration underestimates enterprise-wide exposure and recovery impact.
- Insurance can transfer some monetary consequences but not prevent an outage or remove accountability.
- Shared dependencies can turn apparently independent risks into a correlated loss scenario.
Explanation
Correct Answer
A:Outsourcing technology does not eliminate the customer's business risk ownership. This is the direct weakness in the proposed action.
Incorrect Answers
B:This is a limitation elsewhere: A supplier merger causes the same outsourced identity service to support five formerly independent business units. It does not explain the deficiency of the specified proposed approach.
C:This explains a later shift in requirements (The organization purchases insurance that covers part of the possible financial impact.), not the failure of the current proposal.
D:This is an advantage of another design (Assess concentrated third-party failure risk and include dependency relationships in the enterprise risk register.), not the particular flaw of Claim the vendor alone accepts all healthcare outage risk.
Question 96
A healthcare cloud migration has significant residual availability risk that exceeds approved tolerance despite proposed controls. The organization has now implemented this response: Seek additional treatment or a formally authorized risk decision before accepting residual exposure. Which observation would MOST directly demonstrate that the security objective was met?
- An approved treatment plan shows residual loss, owners and criteria for deployment acceptance.
- Dashboard trends reconcile risk scenarios, control effectiveness and loss or near-miss indicators.
- The analysis documents annualized loss estimates, uncertainty and sensitivity to outage duration.
- An approved change ticket for Seek additional treatment or a formally authorized risk decision before accepting residual exposure. without a completed verification result.
Explanation
Correct Answer
A:An approved treatment plan shows residual loss, owners and criteria for deployment acceptance. This validates that residual risk must be evaluated by the accountable business risk owner against tolerance.
Incorrect Answers
B:This demonstrates controls in another circumstance: An executive committee wants monthly risk dashboards, but the available report counts blocked phishing messages as proof that material risk fell.
C:This other observation is relevant to: A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data.
D:An approved change without an executed test cannot prove operating effectiveness. The needed evidence is An approved treatment plan shows residual loss, owners and criteria for deployment acceptance.
Question 97
A previous security situation was: A healthcare cloud migration has significant residual availability risk that exceeds approved tolerance despite proposed controls. Now the requirement changes: The organization purchases insurance that covers part of the possible financial impact. Which NEW action BEST answers the changed need?
- Update risk assessment to distinguish transferred financial loss from remaining operational and reputational risk.
- Seek additional treatment or a formally authorized risk decision before accepting residual exposure.
- Claim the vendor alone accepts all healthcare outage risk.
- An approved treatment plan shows residual loss, owners and criteria for deployment acceptance.
Explanation
Correct Answer
A:Insurance can transfer some monetary consequences but not prevent an outage or remove accountability. The revised action is Update risk assessment to distinguish transferred financial loss from remaining operational and reputational risk.
Incorrect Answers
B:This is the appropriate response to the original situation: Residual risk must be evaluated by the accountable business risk owner against tolerance. It does not directly meet the new condition.
C:This remains inappropriate: Outsourcing technology does not eliminate the customer's business risk ownership.
D:This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: An approved treatment plan shows residual loss, owners and criteria for deployment acceptance.
Question 98
A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Use only a red-amber-green label with no defined business loss assumptions.
- Add scenario ranges and qualitative judgement rather than presenting false numeric precision.
- Assess concentrated third-party failure risk and include dependency relationships in the enterprise risk register.
- Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option.
Explanation
Correct Answer
D:Frequency and impact estimates can compare expected annualized exposure for competing mitigations.
Incorrect Answers
A:A color label cannot compute the financial tradeoff the owner requests. The proposal would not be defensible for this case.
B:This is appropriate for a later condition (New data shows disruptive incidents are highly uncertain and historical counts are sparse.), but it does not directly resolve the initial need. Uncertainty requires ranges and explicit assumptions, not unjustified point estimates.
C:This response addresses a different condition: A supplier merger causes the same outsourced identity service to support five formerly independent business units. The present case requires the measure described by Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option.
Question 99
A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data. A designer proposes: Use only a red-amber-green label with no defined business loss assumptions. What is the MOST significant security deficiency in this proposal?
- More detections may reflect higher attack volume rather than improved residual risk.
- Uncertainty requires ranges and explicit assumptions, not unjustified point estimates.
- Activity volume is not equivalent to reduced likelihood or business impact.
- A color label cannot compute the financial tradeoff the owner requests.
Explanation
Correct Answer
D:A color label cannot compute the financial tradeoff the owner requests. This is the direct weakness in the proposed action.
Incorrect Answers
A:This is a limitation elsewhere: An executive committee wants monthly risk dashboards, but the available report counts blocked phishing messages as proof that material risk fell. It does not explain the deficiency of the specified proposed approach.
B:This explains a later shift in requirements (New data shows disruptive incidents are highly uncertain and historical counts are sparse.), not the failure of the current proposal.
C:This is an advantage of another design (Measure residual exposure, treatment outcomes and risk indicators against business objectives, not activity counts alone.), not the particular flaw of Use only a red-amber-green label with no defined business loss assumptions.
Question 100
A manufacturer wants to compare loss from server downtime under different restoration speeds and has reliable annual incident data. The organization has now implemented this response: Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option. Which observation would MOST directly demonstrate that the security objective was met?
- A risk register records scenario assumptions, impact dimensions, likelihood bands and review dates.
- The signed exception includes accountable owner, scope, duration, compensating controls and review threshold.
- An approved change ticket for Perform quantitative analysis of estimated event frequency and loss magnitude for each recovery option. without a completed verification result.
- The analysis documents annualized loss estimates, uncertainty and sensitivity to outage duration.
Explanation
Correct Answer
D:The analysis documents annualized loss estimates, uncertainty and sensitivity to outage duration. This validates that frequency and impact estimates can compare expected annualized exposure for competing mitigations.
Incorrect Answers
A:This demonstrates controls in another circumstance: A manufacturing risk assessment scores every scenario 'high' but lacks likelihood assumptions and cannot prioritize investment.
B:This other observation is relevant to: A business owner asks to accept unpatched internet-facing service risk indefinitely because 'nothing has happened yet.'
C:An approved change without an executed test cannot prove operating effectiveness. The needed evidence is The analysis documents annualized loss estimates, uncertainty and sensitivity to outage duration.
