CompTIA CS0-003 Practice Test 84

Question 830

A ransomware tabletop always ends with immediate payment and no recovery decisions. What is the MOST appropriate analyst action based on the evidence?

  1. Capture decision timestamps, handoffs and follow-up actions during the exercise.
  2. Rework the scenario to exercise containment, evidence, restoration and escalation trade-offs.
  3. Update ownership and test the corrected call tree before the next drill.
  4. Include identity, cloud, legal and business owners relevant to that scenario.

Explanation

Correct Answer

B:

A useful exercise tests decision points rather than one scripted outcome. Broaden ransomware tabletop response decisions.

Incorrect Answers

A:

Observed exercise performance guides measurable process improvements. It could help measure tabletop decision bottlenecks, but it would not broaden ransomware tabletop response decisions.

C:

Exercises expose operational readiness failures needing verified correction. It would repair stale tabletop contact roster, but it would not broaden ransomware tabletop response decisions.

D:

Exercises should involve the functions needed for real containment. It could help include proper stakeholders in cloud tabletop, but it would not broaden ransomware tabletop response decisions.

Question 831

Repeated password-reset failures result from help-desk agents bypassing verification steps. Which next step is MOST defensible for the security team?

  1. Report the systemic SDLC defect and recommend secure coding tests and code review.
  2. Target secret-handling coaching and enforce automated repository scanning.
  3. Deliver focused process training and measure adherence to identity proofing.
  4. Add vendor lifecycle assurance to procurement training and approval.

Explanation

Correct Answer

C:

Human procedural weaknesses require behavior and control checks, not one broadcast. Train help desk on secure reset workflow.

Incorrect Answers

A:

Recurring findings call for preventive engineering, not only per-CVE tickets. That is relevant to training and prevention communication, not to train help desk on secure reset workflow.

B:

Education works best when paired with workflow-specific controls. It would prevent recurrent repository credential leaks, but it would not train help desk on secure reset workflow.

D:

Prevention begins before vulnerable unsupported products enter the environment. That is relevant to training and prevention communication, not to train help desk on secure reset workflow.

Question 832

An asset inventory has many retired devices that still appear in recent scan results. Which action BEST aligns with sound security operations?

  1. Request rule effectiveness evidence and residual path review.
  2. Obtain vendor assurance and contractual evidence under approved access paths.
  3. Label them unassessed and plan authorized coverage before declaring compliance.
  4. Reconcile retirement records against actual network observations.

Explanation

Correct Answer

D:

Supposed retirement is not proof an exposed device was removed. Flag apparently retired but reachable assets.

Incorrect Answers

A:

A claimed compensating control needs validated operation. It would verify legacy network isolation control, but it would not flag apparently retired but reachable assets.

B:

Third-party assessments may use different proof methods from network scans. It could help include SaaS risk assurance without illegal scanning, but it would not flag apparently retired but reachable assets.

C:

No scan data cannot be counted as security assurance. That is relevant to asset coverage and lifecycle reporting, not to flag apparently retired but reachable assets.

Question 833

A quarterly briefing highlights patch counts but hides overdue internet-facing critical systems. Which response BEST addresses the security problem described?

  1. Report overdue exposure by criticality and remediation SLO alongside patch volume.
  2. Summarize critical business services, exposure trends and required risk decisions.
  3. Explain reachability, exploit maturity and business impact used to set priorities.
  4. Show the top residual risks and exposure distribution rather than relying on averages.

Explanation

Correct Answer

A:

Activity metrics alone can disguise urgent unmanaged risk. Surface overdue high-impact vulnerabilities.

Incorrect Answers

B:

Executive reporting should translate findings into business impact and accountability. That is relevant to executive vulnerability reporting, not to surface overdue high-impact vulnerabilities.

C:

Transparent risk-based prioritization shows why scores alone do not dictate order. It would justify risk-based vulnerability remediation order, but it would not surface overdue high-impact vulnerabilities.

D:

Mean severity can hide individual high-consequence assets. It could help avoid vulnerability severity averages hiding outliers, but it would not surface overdue high-impact vulnerabilities.

Question 834

The COO wants to know whether ransomware could interrupt warehouse operations, not a list of CVEs. Which investigative or response action BEST fits the evidence?

  1. Distinguish vulnerability potential from observed data access and relevant records.
  2. Link exploitable exposure and recovery dependencies to the warehouse service.
  3. Provide approved reproduction steps and the required authorization boundary.
  4. Compare claimed fix scope against actual inventory and validated versions.

Explanation

Correct Answer

B:

Business-specific scenarios make vulnerability information decision-ready. Answer executive operational continuity concern.

Incorrect Answers

A:

Legal decisions depend on confirmed event facts and applicable obligations. That is relevant to stakeholder expectations and risk evidence, not to answer executive operational continuity concern.

C:

Clear technical evidence supports a targeted root-cause fix. It could help give engineer actionable auth bypass finding, but it would not answer executive operational continuity concern.

D:

Supplier assurance needs asset-level confirmation. That is relevant to stakeholder expectations and risk evidence, not to answer executive operational continuity concern.

Question 835

A finding names a vulnerable application but omits the business owner and change constraints. What is the MOST appropriate analyst action based on the evidence?

  1. Reconcile stable asset identifiers and scan timestamps before maintaining the claim.
  2. Include asset, affected version, exploit path, impact, proposed remedy and validation.
  3. Add service owner, criticality and operational remediation dependencies.
  4. Share minimum necessary technical evidence through access-controlled channels.

Explanation

Correct Answer

C:

Assignable work needs responsibility and feasibility context. Enrich finding with ownership and constraints.

Incorrect Answers

A:

Misattributed scan evidence can send changes to the wrong system. It would correct asset identity in vulnerability report, but it would not enrich finding with ownership and constraints.

B:

Remediation owners need reproducible targeted evidence. It could help write actionable CVE remediation finding, but it would not enrich finding with ownership and constraints.

D:

Vulnerability reports can contain sensitive exploit details. It would restrict exploit detail distribution, but it would not enrich finding with ownership and constraints.

Question 836

A ticket meets its due date but the vulnerable service remains exposed through a standby system. Which next step is MOST defensible for the security team?

  1. Define tiered remediation targets based on risk and business constraints.
  2. Report residual risk and approved exception status transparently.
  3. Define clock start, calendar basis and verified close event uniformly.
  4. Measure verified full-scope mitigation rather than administrative ticket closure.

Explanation

Correct Answer

D:

Incomplete deployment cannot satisfy real remediation objectives. Reject false SLO success on standby exposure.

Incorrect Answers

A:

Different impacts require proportionate response windows. It could help design risk-based remediation service levels, but it would not reject false SLO success on standby exposure.

B:

Risk acceptance changes treatment, not the historical presence of exposure. That is relevant to risk and remediation slo reporting, not to reject false SLO success on standby exposure.

C:

Inconsistent timing rules invalidate SLA comparisons. It would standardize vulnerability SLO clock, but it would not reject false SLO success on standby exposure.

Question 837

A policy requires ten-day critical vulnerability closure but exceptions are approved indefinitely. Which action BEST aligns with sound security operations?

  1. Recommend time-bounded exception governance and periodic reauthorization.
  2. Include active-version verification as a separate completion metric.
  3. Report the change failure, rollback and revised test controls alongside risk reduction.
  4. Group overdue fixes by business service and risk-based priority.

Explanation

Correct Answer

A:

Unlimited exceptions undermine enforceable remediation policy. Report exception governance weakness.

Incorrect Answers

B:

Installed patches may not protect until services restart. It would measure active patch state, but it would not report exception governance weakness.

C:

Balanced reporting captures both security and availability outcomes. It could help report patch-induced business impact, but it would not report exception governance weakness.

D:

Backlog sorting should focus attention on meaningful exposure. That is relevant to patch program governance reporting, not to report exception governance weakness.

Question 838

A report includes screenshots but no timestamps or stable device identifiers. Which response BEST addresses the security problem described?

  1. Identify the benchmark release and explain mapped control differences.
  2. Attach reproducible evidence metadata for controls tested.
  3. Report the exception, residual exposure and approved compensating controls.
  4. Supply appropriately authorized external assessment evidence for applicable systems.

Explanation

Correct Answer

B:

Audit artifacts need traceable asset and observation context. Make compliance evidence reproducible.

Incorrect Answers

A:

Control baseline version is necessary to interpret compliance results. It would disclose baseline version in audit report, but it would not make compliance evidence reproducible.

C:

Incomplete exceptions make compliance statements misleading. That is relevant to compliance and evidence reports, not to make compliance evidence reproducible.

D:

Regulatory test scope and method are part of compliance proof. It would report PCI external scan evidence, but it would not make compliance evidence reproducible.

Question 839

A chart claims vulnerabilities have fallen but scanning frequency halved. Which investigative or response action BEST fits the evidence?

  1. Separate scope expansion from actual risk deterioration in trend charts.
  2. Report recurrence and root-cause process weakness separately from one-time closures.
  3. Include assessed asset and test coverage with the count trend.
  4. Use verified remediation outcomes and distinguish unvalidated closures.

Explanation

Correct Answer

C:

Reduced visibility can create misleading apparent improvement. Disclose declining scan coverage in KPI.

Incorrect Answers

A:

New asset coverage can increase counts without weaker controls. It could help interpret exposure trend after asset discovery, but it would not disclose declining scan coverage in KPI.

B:

Repeat defects indicate remediation-system problems. That is relevant to vulnerability trend and recurrence metrics, not to disclose declining scan coverage in KPI.

D:

Closure status without technical proof is not confirmed risk reduction. It could help measure validated vulnerability closures, but it would not disclose declining scan coverage in KPI.

Question 840

A patch causes an outage during rollout but the report omits operational impact. What is the MOST appropriate analyst action based on the evidence?

  1. Recommend time-bounded exception governance and periodic reauthorization.
  2. Include active-version verification as a separate completion metric.
  3. Group overdue fixes by business service and risk-based priority.
  4. Report the change failure, rollback and revised test controls alongside risk reduction.

Explanation

Correct Answer

D:

Balanced reporting captures both security and availability outcomes. Report patch-induced business impact.

Incorrect Answers

A:

Unlimited exceptions undermine enforceable remediation policy. That is relevant to patch program governance reporting, not to report patch-induced business impact.

B:

Installed patches may not protect until services restart. It would measure active patch state, but it would not report patch-induced business impact.

C:

Backlog sorting should focus attention on meaningful exposure. It could help risk-rank vulnerability patch backlog, but it would not report patch-induced business impact.
