Question 620
A critical trading platform's BIA reports a four-hour RTO while its largest dependent settlement system needs restoration within one hour. What continuing control would best preserve the intended outcome?
- Revisit playbook relevance when threat intelligence and platform changes emerge
- Review mapping accuracy and response speed after incidents or data-system changes
- Review dependency changes whenever trading or settlement architecture changes
- Update notification playbooks after new contracts, insurers, or legal changes
Explanation
Correct Answer
C:Recovery assumptions must match business workflows.
Incorrect Answers
A:Readiness requires current techniques. It may help maintain updating playbooks through incident intelligence, whereas the stated continuing risk concerns reconciling inconsistent business recovery dependencies.
B:Data inventory quality drives notification readiness. It may help maintain preparing a credible breach notification fact base, whereas the stated continuing risk concerns reconciling inconsistent business recovery dependencies.
D:Obligations evolve across agreements and regions. It may help maintain coordinating overlapping reporting obligations, whereas the stated continuing risk concerns reconciling inconsistent business recovery dependencies.
Question 621
A security leader proposes activating disaster recovery after every phishing alert. What is the MOST appropriate first management decision for this situation?
- Use approved recovery criteria that include integrity, confidentiality, and RTO commitments
- Use business-impact-driven activation criteria to differentiate investigation, incident response, and continuity actions
- Develop a business-continuity fallback for dispatch processes based on BIA priorities
- Design continuity exercises around critical business transactions and their dependencies
Explanation
Correct Answer
B:Overreaction creates avoidable disruption without improving risk management.
Incorrect Answers
A:Rapid restoration is not success if records are corrupted or compromised. However, it does not make the decision needed for selecting proportional incident response activation thresholds in this scenario.
C:Service resilience requires alternate ways to perform essential operations. However, it does not make the decision needed for selecting proportional incident response activation thresholds in this scenario.
D:A restored server does not prove that an end-to-end process works. However, it does not make the decision needed for selecting proportional incident response activation thresholds in this scenario.
Question 622
A security leader proposes activating disaster recovery after every phishing alert. What should the manager arrange during rollout to meet this requirement?
- Document escalation thresholds and decision rights for response and recovery plan activation
- Map critical processing chains and negotiate aligned recovery sequencing and capacity
- Establish handoff criteria, evidence capture, and approval roles for response actions
- Document critical dependency order and failure assumptions before test execution
Explanation
Correct Answer
A:A tiered process matches severity to action.
Incorrect Answers
B:Recovery objectives must be internally consistent. That could support reconciling inconsistent business recovery dependencies, but it does not implement the requested selecting proportional incident response activation thresholds.
C:A formal transition protects investigations and operations. That could support separating investigation from authorized response, but it does not implement the requested selecting proportional incident response activation thresholds.
D:Realistic exercises reflect business architecture. That could support testing multi-service disaster dependencies, but it does not implement the requested selecting proportional incident response activation thresholds.
Question 623
A security leader proposes activating disaster recovery after every phishing alert. Which test most directly verifies the desired managerial outcome?
- Verify a corrective plan assigns owners, due dates, and measurable closure evidence
- Simulate a phishing attempt and a confirmed operational compromise and verify different appropriate responses
- Verify malicious messages are quarantined while approved business mail continues
- Restore a representative application and verify integrity, RTO, and RPO performance
Explanation
Correct Answer
B:A comparison tests proportionality.
Incorrect Answers
A:Lessons need implementation, not only a meeting. This provides evidence for using post-incident review to improve controls, not proof of selecting proportional incident response activation thresholds.
C:Positive and negative tests measure containment quality. This provides evidence for choosing proportional email containment, not proof of selecting proportional incident response activation thresholds.
D:Business outcomes validate recovery capability. This provides evidence for testing business continuity assumptions, not proof of selecting proportional incident response activation thresholds.
Question 624
A security leader proposes activating disaster recovery after every phishing alert. After deployment, what ongoing oversight most directly keeps the requirement effective?
- Review late escalations and update thresholds when classification mistakes recur
- Review false activations and missed escalations to recalibrate criteria
- Review campaign indicators and blocking false positives after the event
- Review criteria after material incidents and changed business dependencies
Explanation
Correct Answer
B:The thresholds should respond to evidence.
Incorrect Answers
A:Learning from missed signs improves triage. It may help maintain updating incident severity during investigation, whereas the stated continuing risk concerns selecting proportional incident response activation thresholds.
C:Threat patterns and legitimate communications change. It may help maintain choosing proportional email containment, whereas the stated continuing risk concerns selecting proportional incident response activation thresholds.
D:Severity scales must reflect current consequences. It may help maintain classifying incidents according to business severity, whereas the stated continuing risk concerns selecting proportional incident response activation thresholds.
Question 625
A government agency needs to preserve incident evidence but its response plan encourages indiscriminate system rebuilding. Which management approach best satisfies the primary requirement?
- Define the incident triage, classification, and escalation process with legal notification triggers
- Conduct a root-cause and control-gap review with accountable remediation owners
- Require evidence-handling and legal-hold decisions before destructive remediation when feasible
- Establish an incident governance model with legal, communications, business, and technical responsibilities
Explanation
Correct Answer
C:Premature rebuilding can destroy material forensic evidence.
Incorrect Answers
A:Consistent interpretation reduces late reporting. However, it does not make the decision needed for incorporating evidence preservation into containment in this scenario.
B:Service recovery alone does not eliminate systemic weaknesses. However, it does not make the decision needed for incorporating evidence preservation into containment in this scenario.
D:Major incidents affect more than infrastructure and need coordinated decisions. However, it does not make the decision needed for incorporating evidence preservation into containment in this scenario.
Question 626
A government agency needs to preserve incident evidence but its response plan encourages indiscriminate system rebuilding. Which concrete action would best operationalize the needed approach?
- Define measures for detection, escalation, containment, recovery, and exception causes
- Define capture order, chain-of-custody records, authorized imaging, and safe containment constraints
- Use business-owned reconciliations and safe transaction replay procedures before normal operations
- Document critical dependency order and failure assumptions before test execution
Explanation
Correct Answer
B:Responders need a defensible sequence.
Incorrect Answers
A:Multiple stages expose bottlenecks. That could support improving incident response performance reporting, but it does not implement the requested incorporating evidence preservation into containment.
C:Controlled data repair reduces secondary losses. That could support managing business validation after technical recovery, but it does not implement the requested incorporating evidence preservation into containment.
D:Realistic exercises reflect business architecture. That could support testing multi-service disaster dependencies, but it does not implement the requested incorporating evidence preservation into containment.
Question 627
A government agency needs to preserve incident evidence but its response plan encourages indiscriminate system rebuilding. Which evidence best demonstrates the intended business and security outcome?
- Test the dependency chain end to end and compare actual completion with the tightest business requirement
- Inspect a test incident for preserved artifacts, timestamps, and documented custody transitions
- Reconstruct a sampled containment decision from the incident log and artifacts
- Restore a representative clean backup in an isolated test and verify business integrity
Explanation
Correct Answer
B:An evidence audit checks admissibility and integrity.
Incorrect Answers
A:An isolated server restore can hide process failure. This provides evidence for reconciling inconsistent business recovery dependencies, not proof of incorporating evidence preservation into containment.
C:Traceability confirms documentation quality. This provides evidence for maintaining auditable incident documentation, not proof of incorporating evidence preservation into containment.
D:A tested point confirms recovery confidence. This provides evidence for planning clean restoration after destructive compromise, not proof of incorporating evidence preservation into containment.
