CompTIA CS0-003 Practice Test 92

Question 910

A hotfix is deployed directly to production and later causes outages. What is the MOST appropriate analyst action based on the evidence?

  1. Tie vulnerability recurrence to software build and release controls.
  2. Report emergency authorization, testing gaps and corrective change practices.
  3. Verify patch state through alternate authorized credentials before declaring fixed.
  4. Document verified operational constraints and controlled alternate safeguards.

Explanation

Correct Answer

B:

Risk treatment must include safe execution and traceable governance. Report emergency patch change control defect.

Incorrect Answers

A:

Reintroduced components indicate supply-chain or build policy drift. It would report reintroduced vulnerable dependency, but it would not report emergency patch change control defect.

C:

Scanner reachability loss is not software remediation. That is relevant to change management link to vulnerabilities, not to report emergency patch change control defect.

D:

Regulated or certified equipment may need nonstandard safe remediation sequences. It would explain regulated asset patch constraint, but it would not report emergency patch change control defect.

Question 911

A scan report marks endpoints clean because network filters blocked every probe. Which next step is MOST defensible for the security team?

  1. Redact secrets and limit report access while protecting original secured evidence.
  2. Add affected components, exploit prerequisites and business risk interpretation.
  3. Identify coverage failure and request a retest; never report a true negative.
  4. Include the rating methodology and relevant environmental adjustments.

Explanation

Correct Answer

C:

An inaccessible target has unknown vulnerability status. Correct inaccurate scan pass report.

Incorrect Answers

A:

Reports can create new disclosure paths for captured credentials. It could help remove secrets from distributed scanner evidence, but it would not correct inaccurate scan pass report.

B:

Implementers need scope and managers need relevant consequences. That is relevant to scanner-to-stakeholder communication integrity, not to correct inaccurate scan pass report.

D:

Readers need scoring definitions to interpret severity consistently. It could help disclose proprietary scanner severity basis, but it would not correct inaccurate scan pass report.

Question 912

A cloud platform rolls out managed patching but the customer cannot prove individual instances are fixed. Which action BEST aligns with sound security operations?

  1. Report an asset verification task and uncertainty before declaring enterprise exposure.
  2. Present the security risk and operational impact for an authorized decision.
  3. Escalate changed urgency and communicate revised interim controls.
  4. Request provider or management evidence of affected-version closure.

Explanation

Correct Answer

D:

Outsourced patching does not remove the need for assurance. Validate managed cloud patch status.

Incorrect Answers

A:

Unknown inventory is not proof of either vulnerability or safety. That is relevant to emerging vulnerability risk and monitoring, not to validate managed cloud patch status.

B:

Executives need both cyber and service consequences to choose containment. It would communicate safe emergency shutdown trade-off, but it would not validate managed cloud patch status.

C:

Confirmed active exploitation shifts likelihood and remediation priority. It could help update remediation after active exploitation, but it would not validate managed cloud patch status.

Question 913

A hospital cannot patch an unsupported operating system without taking a diagnostic service offline. Which response BEST addresses the security problem described?

  1. Report business constraint, temporary isolation, owner-approved plan and replacement timeline.
  2. Report live exposure and a short-term isolation plan despite future retirement.
  3. Document contractual restriction and agree on vendor-managed remediation and interim controls.
  4. Present delayed patch impact and temporary safeguards for accountable risk approval.

Explanation

Correct Answer

A:

Legacy remediation reporting must balance patient service availability with risk. Document legacy system patch blocker.

Incorrect Answers

B:

Future disposal does not remove present vulnerability. It could help communicate interim retired-device risk, but it would not document legacy system patch blocker.

C:

Unilateral patching may violate support terms and operational assurances. That is relevant to legacy system remediation inhibitors, not to document legacy system patch blocker.

D:

Business process timing can justify controlled sequencing, not silent neglect. It would report finance maintenance freeze risk, but it would not document legacy system patch blocker.

Question 914

A developer team repeatedly reintroduces SQL injection after each release. Which investigative or response action BEST fits the evidence?

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

Explanation

Correct Answer

B:

Recurring findings call for preventive engineering, not only per-CVE tickets. Communicate recurring secure coding gap.

Incorrect Answers

A:

Education works best when paired with workflow-specific controls. It could help prevent recurrent repository credential leaks, but it would not communicate recurring secure coding gap.

C:

Human procedural weaknesses require behavior and control checks, not one broadcast. It would train help desk on secure reset workflow, but it would not communicate recurring secure coding gap.

D:

Prevention begins before vulnerable unsupported products enter the environment. It could help teach secure supplier lifecycle selection, but it would not communicate recurring secure coding gap.

Question 915

A risk exception's scope says one server but its implementation excludes an entire subnet. What is the MOST appropriate analyst action based on the evidence?

  1. Clearly record continued vulnerability, residual impact and control conditions.
  2. Trigger reassessment and notify the responsible owner with new reachability evidence.
  3. Correct the scope and report unauthorized residual exposure.
  4. Route acceptance to the accountable authorized risk owner.

Explanation

Correct Answer

C:

Broader exceptions may conceal significant unapproved risk. Identify exception-control scope mismatch.

Incorrect Answers

A:

Risk acceptance is a governance decision, not technical remediation. That is relevant to risk acceptance reporting and governance, not to identify exception-control scope mismatch.

B:

Exposure changes invalidate old treatment assumptions. It would reopen expired or changed vulnerability acceptance, but it would not identify exception-control scope mismatch.

D:

Third parties cannot accept organizational exposure without proper authority. That is relevant to risk acceptance reporting and governance, not to identify exception-control scope mismatch.

Question 916

A legacy application is declared 'compensated' based on a firewall rule no one has tested. Which next step is MOST defensible for the security team?

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

Explanation

Correct Answer

D:

A claimed compensating control needs validated operation. Verify legacy network isolation control.

Incorrect Answers

A:

Third-party assessments may use different proof methods from network scans. It would include SaaS risk assurance without illegal scanning, but it would not verify legacy network isolation control.

B:

No scan data cannot be counted as security assurance. It could help correct unassessed segmented systems report, but it would not verify legacy network isolation control.

C:

Supposed retirement is not proof an exposed device was removed. That is relevant to asset coverage and lifecycle reporting, not to verify legacy network isolation control.

Question 917

The scan evidence references a private customer hostname that should not be publicly disclosed. Which action BEST aligns with sound security operations?

  1. Restrict the report to approved recipients and mask identifying details in external copies.
  2. Obtain effective installed version and runtime verification output.
  3. Present risk approval, interim mitigations, ownership and dated remediation evidence.
  4. Maintain a canonical remediation register with evidence-backed owner approvals.

Explanation

Correct Answer

A:

Disclosure of asset naming can increase reconnaissance risk. Safeguard confidential vulnerability report data.

Incorrect Answers

B:

Executing an installer does not prove successful remediation. That is relevant to audit-ready vulnerability disposition, not to safeguard confidential vulnerability report data.

C:

Defensible exceptions need a documented decision trail. It would justify overdue vulnerability audit trail, but it would not safeguard confidential vulnerability report data.

D:

Consolidated records prevent contradictory closure claims across tools. It could help coordinate cross-vendor vulnerability evidence, but it would not safeguard confidential vulnerability report data.

Question 918

An asset owner requests prolonged remediation because upgrades may break certification status. Which response BEST addresses the security problem described?

  1. Verify patch state through alternate authorized credentials before declaring fixed.
  2. Document verified operational constraints and controlled alternate safeguards.
  3. Tie vulnerability recurrence to software build and release controls.
  4. Report emergency authorization, testing gaps and corrective change practices.

Explanation

Correct Answer

B:

Regulated or certified equipment may need nonstandard safe remediation sequences. Explain regulated asset patch constraint.

Incorrect Answers

A:

Scanner reachability loss is not software remediation. That is relevant to change management link to vulnerabilities, not to explain regulated asset patch constraint.

C:

Reintroduced components indicate supply-chain or build policy drift. It could help report reintroduced vulnerable dependency, but it would not explain regulated asset patch constraint.

D:

Risk treatment must include safe execution and traceable governance. That is relevant to change management link to vulnerabilities, not to explain regulated asset patch constraint.

Question 919

A business leader wants a single remediation SLA for all vulnerabilities regardless of risk. Which investigative or response action BEST fits the evidence?

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

Explanation

Correct Answer

C:

Different impacts require proportionate response windows. Design risk-based remediation service levels.

Incorrect Answers

A:

Risk acceptance changes treatment, not the historical presence of exposure. It would disclose exceptions in SLO reporting, but it would not design risk-based remediation service levels.

B:

Inconsistent timing rules invalidate SLA comparisons. It could help standardize vulnerability SLO clock, but it would not design risk-based remediation service levels.

D:

Incomplete deployment cannot satisfy real remediation objectives. It would reject false SLO success on standby exposure, but it would not design risk-based remediation service levels.

Question 920

A weekly report shows zero vulnerabilities on systems never scanned due to network segmentation. What is the MOST appropriate analyst action based on the evidence?

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

Explanation

Correct Answer

D:

No scan data cannot be counted as security assurance. Correct unassessed segmented systems report.

Incorrect Answers

A:

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 correct unassessed segmented systems report.

B:

Supposed retirement is not proof an exposed device was removed. That is relevant to asset coverage and lifecycle reporting, not to correct unassessed segmented systems report.

C:

A claimed compensating control needs validated operation. It would verify legacy network isolation control, but it would not correct unassessed segmented systems report.
