Question 630
A supplier reports a breach affecting data hosted for several business units, but each unit plans independent customer communications. During implementation, which action most directly executes the necessary response?
- Correlate shared indicators, affected identities, and business criticality within one incident process
- Establish handoff criteria, evidence capture, and approval roles for response actions
- Document severity triggers, responsible roles, alternates, and approval channels in the response plan
- Create one authoritative fact log, affected-party map, approval chain, and reporting calendar
Explanation
Correct Answer
D:Shared information reduces contradictory external statements.
Incorrect Answers
A:Clustering reduces duplicate work and directs response. That could support coordinating triage under incident volume, but it does not implement the requested coordinating cross-business incident communications.
B:A formal transition protects investigations and operations. That could support separating investigation from authorized response, but it does not implement the requested coordinating cross-business incident communications.
C:Explicit authority reduces delays during crises. That could support establishing crisis decision authority, but it does not implement the requested coordinating cross-business incident communications.
Question 631
A supplier reports a breach affecting data hosted for several business units, but each unit plans independent customer communications. What would provide the strongest practical verification of this requirement?
- Run a tabletop where the incident commander is unavailable and verify a qualified delegate declares the incident
- Restore a representative application and verify integrity, RTO, and RPO performance
- Run a ransomware scenario that requires both isolation and production recovery decisions
- Walk through a multi-jurisdiction notification scenario and verify coordinated timely approvals
Explanation
Correct Answer
D:A scenario tests who speaks and when.
Incorrect Answers
A:The exercise tests continuity of decision authority. This provides evidence for establishing crisis decision authority, not proof of coordinating cross-business incident communications.
B:Business outcomes validate recovery capability. This provides evidence for testing business continuity assumptions, not proof of coordinating cross-business incident communications.
C:An integrated exercise exposes plan conflicts. This provides evidence for aligning incident response with recovery and continuity, not proof of coordinating cross-business incident communications.
Question 632
A supplier reports a breach affecting data hosted for several business units, but each unit plans independent customer communications. Which follow-up is most relevant as the environment changes?
- Amend future contracts to include evidence, notification, and response obligations

- Review notification templates and jurisdictions after changes in service footprint
- Revisit playbook relevance when threat intelligence and platform changes emerge
Explanation
Correct Answer
C:Communication obligations can shift.
Incorrect Answers
A:Corrective action should prevent recurrence. It may help maintain handling an urgent supplier breach despite contract ambiguity, whereas the stated continuing risk concerns coordinating cross-business incident communications.
B:Data inventory quality drives notification readiness. It may help maintain preparing a credible breach notification fact base, whereas the stated continuing risk concerns coordinating cross-business incident communications.
D:Readiness requires current techniques. It may help maintain updating playbooks through incident intelligence, whereas the stated continuing risk concerns coordinating cross-business incident communications.
Question 633
A response plan is reviewed every year but responders cannot locate credentials or tooling during an outage. Which management decision most directly addresses the stated business need?
- Validate availability of emergency access, evidence tools, and communications under degraded conditions
- Create a centralized incident record of facts, evidence, decisions, and chronology
- Establish an incident governance model with legal, communications, business, and technical responsibilities
- Route public communication through authorized incident communications and legal approval
Explanation
Correct Answer
A:A documented plan fails without usable resources.
Incorrect Answers
B:An incident record supports coordination, legal duties, and lessons learned. However, it does not make the decision needed for making incident response resources operationally ready in this scenario.
C:Major incidents affect more than infrastructure and need coordinated decisions. However, it does not make the decision needed for making incident response resources operationally ready in this scenario.
D:Premature disclosure can impede containment, evidence, or legal obligations. However, it does not make the decision needed for making incident response resources operationally ready in this scenario.
Question 634
A response plan is reviewed every year but responders cannot locate credentials or tooling during an outage. Which implementation step best translates the requirement into an operating control?
- Define activation contacts, emergency authorization, evidence sharing, and access boundaries
- Require structured shift briefings, decision logs, and named acceptance of handover
- Define service levels, contact paths, data access, jurisdictional obligations, and authority limits
- Maintain controlled break-glass access and offline runbooks with named custodians
Explanation
Correct Answer
D:Resilience requires secure access when primary systems fail.
Incorrect Answers
A:Readiness needs workable details. That could support making retainer services operational during a crisis, but it does not implement the requested making incident response resources operationally ready.
B:Explicit responsibility supports continuity. That could support improving incident command continuity across shifts, but it does not implement the requested making incident response resources operationally ready.
C:Contract terms should work in a real crisis. That could support governing managed incident response contract boundaries, but it does not implement the requested making incident response resources operationally ready.
Question 635
A response plan is reviewed every year but responders cannot locate credentials or tooling during an outage. Which validation best confirms the control meets the stated need?
- Run a tabletop where the incident commander is unavailable and verify a qualified delegate declares the incident
- Exercise incident activation with primary identity and ticketing systems unavailable
- Verify a controlled exercise isolates the highest-risk hosts within tolerated downtime
- Run a clock-based incident exercise and verify each notification is sent or documented on time
Explanation
Correct Answer
B:A degraded-mode test exposes resource dependencies.
Incorrect Answers
A:The exercise tests continuity of decision authority. This provides evidence for establishing crisis decision authority, not proof of making incident response resources operationally ready.
C:A timed test checks decision and execution speed. This provides evidence for making proportionate urgent containment decisions, not proof of making incident response resources operationally ready.
D:Timing is a real compliance outcome. This provides evidence for coordinating overlapping reporting obligations, not proof of making incident response resources operationally ready.
Question 636
A response plan is reviewed every year but responders cannot locate credentials or tooling during an outage. What continuing control would best preserve the intended outcome?
- Track lessons and retest unresolved readiness gaps after corrective action
- Review untested business dependencies and update continuity plans after each drill
- Review emergency contact reachability and independent access periodically
- Review emergency credentials and tool readiness at scheduled intervals
Explanation
Correct Answer
D:Unused recovery resources can become unusable.
Incorrect Answers
A:Exercises should improve capability rather than generate attendance. It may help maintain making incident exercises test decision readiness, whereas the stated continuing risk concerns making incident response resources operationally ready.
B:Operational reality changes beyond IT diagrams. It may help maintain testing end-to-end business continuity outcomes, whereas the stated continuing risk concerns making incident response resources operationally ready.
C:Alternative channels can fail through stale data. It may help maintain planning alternate emergency communications, whereas the stated continuing risk concerns making incident response resources operationally ready.
Question 637
A business is preparing for ransomware and must choose between its latest backups and verified clean recovery points. What is the MOST appropriate first management decision for this situation?
- Define recovery decisions based on verified backup integrity and compromise timelines
- Assign incident classification and declaration authority with backup escalation paths
- Define when hunting findings trigger incident classification and authorized containment decisions
- Develop a business-continuity fallback for dispatch processes based on BIA priorities
Explanation
Correct Answer
A:The newest copy may contain malware or corrupted data.
Incorrect Answers
B:Timely incident declaration requires a clearly accountable decision-maker. However, it does not make the decision needed for planning clean restoration after destructive compromise in this scenario.
C:Hunting generates leads; disruptive actions require controlled authority. However, it does not make the decision needed for planning clean restoration after destructive compromise in this scenario.
D:Service resilience requires alternate ways to perform essential operations. However, it does not make the decision needed for planning clean restoration after destructive compromise in this scenario.
Question 638
