CompTIA CS0-003 Practice Test 83

Question 820

An exercise simulates a cloud identity breach but includes only network engineers. What is the MOST appropriate analyst action based on the evidence?

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

Explanation

Correct Answer

D:

Exercises should involve the functions needed for real containment. Include proper stakeholders in cloud tabletop.

Incorrect Answers

A:

A useful exercise tests decision points rather than one scripted outcome. It would broaden ransomware tabletop response decisions, but it would not include proper stakeholders in cloud tabletop.

B:

Exercises expose operational readiness failures needing verified correction. It could help repair stale tabletop contact roster, but it would not include proper stakeholders in cloud tabletop.

C:

Observed exercise performance guides measurable process improvements. That is relevant to tabletop exercise design, not to include proper stakeholders in cloud tabletop.

Question 821

An incident response plan lists technical activities but no authority to disconnect customer services. Which next step is MOST defensible for the security team?

  1. Assign accountable incident command and business-impact approval roles.
  2. Maintain tested on-call routing and backup contacts in the response plan.
  3. Establish severity thresholds and notification paths tied to business impact.
  4. Separate technical evidence duties from approved communications authority.

Explanation

Correct Answer

A:

Disruptive containment requires clear decision authority before an emergency. Define incident containment authorization.

Incorrect Answers

B:

Time-critical response depends on contact availability beyond business hours. That is relevant to ir plan roles and escalation, not to define incident containment authorization.

C:

Consistent declaration criteria prevent delayed or excessive escalation. It would standardize major incident declaration threshold, but it would not define incident containment authorization.

D:

Specialized roles improve accuracy and reduce unauthorized disclosure. It could help segregate response evidence and public communication roles, but it would not define incident containment authorization.

Question 822

A phishing playbook tells analysts to reset passwords but not to revoke existing sessions. Which action BEST aligns with sound security operations?

  1. Update and test the workflow against deployed tooling before declaring it ready.
  2. Add token/session revocation and verify access invalidation steps.
  3. Add evidence and approval thresholds for disruptive enforcement actions.
  4. Define retention, custody and legal hold pathways with policy owners.

Explanation

Correct Answer

B:

Password resets alone may leave stolen sessions active. Improve phishing playbook token coverage.

Incorrect Answers

A:

Playbooks become unsafe when tooling or APIs change. That is relevant to playbook lifecycle and validation, not to improve phishing playbook token coverage.

C:

Automated containment must match the confidence and risk of detection. It could help constrain SOAR action trigger in playbook, but it would not improve phishing playbook token coverage.

D:

Evidence preservation requirements continue after immediate technical response. That is relevant to playbook lifecycle and validation, not to improve phishing playbook token coverage.

Question 823

A ransomware incident attributes impact entirely to one user click while backups were accessible to attackers. Which response BEST addresses the security problem described?

  1. Compare change sequence and actual failure mechanisms before attributing causation.
  2. Investigate the authentication control gap and policy exceptions separately from the initial lure.
  3. Include privileged backup access and segmentation failures in root cause review.
  4. Continue initial-access investigation or document the unknown entry vector explicitly.

Explanation

Correct Answer

C:

Systemic controls influence severity beyond initial access. Analyze ransomware backup control contribution.

Incorrect Answers

A:

Chronological proximity alone does not prove technical cause. It would validate causal root of patch-induced outage, but it would not analyze ransomware backup control contribution.

B:

Trigger events and systemic enabling weaknesses are not always the same cause. It could help identify underlying control gap in phishing incident, but it would not analyze ransomware backup control contribution.

D:

Naming malware is not equivalent to establishing root cause. It would distinguish malware label from initial access cause, but it would not analyze ransomware backup control contribution.

Question 824

A tabletop audit compares two drills with different scopes but claims percentage improvement. Which investigative or response action BEST fits the evidence?

  1. Define detection-time metrics across all eligible incidents consistently.
  2. Update the impact report with time-stamped revised estimates and evidence.
  3. Measure verified recovery/eradication milestones rather than administrative closure.
  4. Normalize scenario complexity and decision criteria before trend comparison.

Explanation

Correct Answer

D:

Exercise metrics require comparable conditions for meaningful conclusions. Calibrate tabletop performance comparison.

Incorrect Answers

A:

Selection bias can make process improvement look better than reality. It could help avoid biased incident detection metrics, but it would not calibrate tabletop performance comparison.

B:

Incident impact assessment may evolve as downstream losses become known. That is relevant to after-action metric improvement, not to calibrate tabletop performance comparison.

C:

Correct outcome measurement prevents premature success reporting. It would align IR remediation KPI to validation, but it would not calibrate tabletop performance comparison.

Question 825

Executives attend a tabletop but no one records which decisions took too long. What is the MOST appropriate analyst action based on the evidence?

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

Explanation

Correct Answer

A:

Observed exercise performance guides measurable process improvements. Measure tabletop decision bottlenecks.

Incorrect Answers

B:

Exercises expose operational readiness failures needing verified correction. It would repair stale tabletop contact roster, but it would not measure tabletop decision bottlenecks.

C:

A useful exercise tests decision points rather than one scripted outcome. It could help broaden ransomware tabletop response decisions, but it would not measure tabletop decision bottlenecks.

D:

Exercises should involve the functions needed for real containment. That is relevant to tabletop exercise design, not to measure tabletop decision bottlenecks.

Question 826

A response plan includes legal team contacts but no owner for regulator notifications. Which next step is MOST defensible for the security team?

  1. Test authenticated communication and emergency escalation between provider and organization.
  2. Assign notification decision owner and required timing checkpoints.
  3. Establish an out-of-band secure communications plan and exercise it.
  4. Provision approved emergency vault access and prohibit secret sharing.

Explanation

Correct Answer

B:

Regulatory deadlines need explicit accountable workflow. Establish breach regulator-notification ownership.

Incorrect Answers

A:

Response coordination fails when channels are missing or compromised. It would test outsourced SOC communication route, but it would not establish breach regulator-notification ownership.

C:

Compromised communications can leak response strategy to attackers. That is relevant to communication and coordination preparedness, not to establish breach regulator-notification ownership.

D:

Incident urgency does not justify exposing high-value credentials. It would secure emergency access during incident response, but it would not establish breach regulator-notification ownership.

Question 827

A firm wants to restore its customer portal before the database and DNS services it requires. Which action BEST aligns with sound security operations?

  1. Rank recovery using business impact, safety and maximum tolerable downtime.
  2. Add systemic outage scenarios that affect shared authentication and network dependencies.
  3. Use dependency-based recovery order informed by business impact analysis.
  4. Rotate secret material as part of validated clean restoration.

Explanation

Correct Answer

C:

Recovered frontends cannot function without critical upstream services. Sequence recovery according to dependencies.

Incorrect Answers

A:

Risk-based prioritization protects essential services first. It could help apply BIA to recovery restoration order, but it would not sequence recovery according to dependencies.

B:

Single-host tests may miss common-mode failures. That is relevant to recovery dependency and prioritization, not to sequence recovery according to dependencies.

D:

Backup restoration may reproduce credential compromise. It could help eliminate secrets retained in recovery snapshot, but it would not sequence recovery according to dependencies.

Question 828

A tabletop identifies a missing identity log source but the lesson remains a meeting note. Which response BEST addresses the security problem described?

  1. Add a central timestamped response decision log to the playbook.
  2. Validate improvements through follow-up exercises and targeted technical tests.
  3. Address remediation governance and recurring technical debt across the program.
  4. Assign a telemetry owner, deadline and verification criterion to the improvement.

Explanation

Correct Answer

D:

Lessons only reduce future risk when converted into accountable work. Operationalize detection coverage lesson.

Incorrect Answers

A:

Incident decisions require traceable authorization and handoffs. That is relevant to postincident lessons learned, not to operationalize detection coverage lesson.

B:

Written changes do not prove operational effectiveness. It would verify postincident improvement in exercise, but it would not operationalize detection coverage lesson.

C:

Pattern analysis reveals systemic causes across individual incident records. It could help eliminate recurring incident root vulnerability, but it would not operationalize detection coverage lesson.

Question 829

A business continuity plan covers data center loss but omits dependency on an identity provider. Which investigative or response action BEST fits the evidence?

  1. Include identity and authentication dependencies in the impact analysis.
  2. Include trusted network configuration and security-control recovery dependencies.
  3. Revise capability or recovery strategy to meet agreed recovery objectives.
  4. Improve backup frequency or replication to satisfy required data-loss tolerance.

Explanation

Correct Answer

A:

Services cannot recover if their external identity dependencies remain unavailable. Include IAM dependency in business continuity.

Incorrect Answers

B:

Recovered workloads should not return without necessary protective controls. It could help restore security controls in disaster recovery, but it would not include IAM dependency in business continuity.

C:

Recovery-time promises must reflect demonstrated operational capability. That is relevant to business continuity and disaster recovery, not to include IAM dependency in business continuity.

D:

RPO governs acceptable data age, not simply service availability. It would close unacceptable RPO data loss, but it would not include IAM dependency in business continuity.

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.
