Question 50
Response staff seek a controlled first step after this problem: Incident owners repeatedly close cases without documenting root cause or detection gaps. The manager needs a check that verifies the issue AND an immediate controlled assignment or safeguard. Which TWO case-specific steps fulfill those distinct roles? (Choose TWO.)
- Reopen the improvement review and assign corrective-action owners
- Track detection and control fixes to evidence-backed completion
- Track root-cause remediation as a required closure dependency
- Require intake forms with time, source, severity, affected assets and owner
- Review closed case records for corrective actions and unresolved causal factors
- Make a blameless post-incident review a required high-severity milestone
Explanation
Correct Answers
A:A documented follow-up prevents recurring problems from being buried at closure; within the combined response for what post-incident learning is missing, this supplies immediate response coordination: this protective or assignment decision directly addresses what post-incident learning is missing while response governance is still active.
E:A complete lessons-learned record should identify why controls failed or succeeded; within the combined response for what post-incident learning is missing, this supplies process validation: this provides an auditable basis for the disputed finding: what post-incident learning is missing.
Incorrect Answers
B:Measured remediation converts the review into preventive change; the requirement concerns what post-incident learning is missing, so corrective follow-through follows initial protection.
C:Technical closure should include all enabling weaknesses, not just file removal; this serves whether eradication removed the attack's persistence, whereas the requested result is immediate response coordination involving what post-incident learning is missing.
D:Consistent minimum fields improve triage and handoff; this serves how incident recording supports traceability, whereas the requested result is immediate response coordination involving what post-incident learning is missing.
F:Structured learning improves response without punishing accurate reporting; when judging what post-incident learning is missing, prevention cannot replace immediate action; this is instead readiness improvement.
Question 51
A procedural case requires a near-term protective assignment: An analyst wants to notify affected customers immediately after a suspected personal-data leak without consulting legal counsel. Select TWO actions covering procedural assessment and an authorized near-term response—not full process redesign. (Choose TWO.)
- Document the notification decision, recipients, deadlines and legal basis
- Embed jurisdiction-specific privacy triggers in the response notification matrix
- Restore business operations only from an authorized clean replacement
- Maintain a reviewed jurisdiction-and-contract notification register
- Escalate to privacy and legal owners while preserving factual incident details
- Establish data categories, affected jurisdictions, certainty and exposure timeline
Explanation
Correct Answers
E:Authorized review avoids an inaccurate or prematurely broad external disclosure; within the combined response for whether notification requirements are factually triggered, this supplies immediate response coordination: the immediate coordination decision concerns whether notification requirements are factually triggered; it keeps the response process under explicit control.
F:Applicable notice rules depend on governing law and the actual nature of the breach; within the combined response for whether notification requirements are factually triggered, this supplies process validation: the review establishes whether notification requirements are factually triggered so that responsibility and next decisions rest on a recorded result.
Incorrect Answers
A:A reviewable decision trail supports timely compliance when duties apply; when judging whether notification requirements are factually triggered, corrective follow-through follows initial protection; this is instead procedural correction.
B:Preplanned legal routing minimizes missed deadlines and unauthorized statements; for whether notification requirements are factually triggered, prevention cannot replace immediate action; immediate response coordination remains necessary.
C:Separating working systems from retained evidence avoids destroying potentially material data; the other incident centers on how to reconcile evidence preservation with operational recovery, not this immediate response coordination question about whether notification requirements are factually triggered.
D:Legal and vendor requirements can be checked rapidly during an incident; it is meant to address which legal requirements govern notification timing, not immediate response coordination for whether notification requirements are factually triggered.
Question 52
The owner is reconciling responder actions with the approved plan after: A response plan cites NIST SP 800-61 Revision 2 as the latest guidance in a 2026 audit. Which follow-up would repair the reported response-management failure?
- Update the plan's references and map its workflow to CSF 2.0 functions
- Map incident response capabilities to CSF functions and forensic SOPs
- Schedule periodic review of external standard references and change notices
- Check the publication revision and supersession notice in NIST CSRC
- Flag the reference for governance correction without abandoning active response procedures
Explanation
Correct Answer
A:Revision 3 is a CSF 2.0 community profile rather than a mere renumbering of the old phase list; the correction restores accountability or sequence for whether cited incident-response guidance is current before case sign-off.
Incorrect Answers
B:Complementary guidance avoids treating a framework as a detailed tool runbook; this serves what CSF 2.0 actually organizes, whereas the requested result is procedural correction involving whether cited incident-response guidance is current.
C:Document owners can update playbooks when authoritative guidance changes; the goal is procedural correction for whether cited incident-response guidance is current. Future hardening is not current-state recovery.
D:NIST finalized Revision 3 in April 2025, replacing the 2012 guide; verification is not the corrective step in the decision about whether cited incident-response guidance is current.
E:A citation update must not interrupt evidence preservation during a live incident; the case needs procedural correction addressing whether cited incident-response guidance is current; temporary protection does not complete correction.
Question 53
An immediate process decision is needed for the following concern: Before a breach, the organization has no access to offline recovery credentials or responder contact numbers. Select TWO actions covering procedural assessment and an authorized near-term response—not full process redesign. (Choose TWO.)
- Validate break-glass credentials and store approved recovery materials offline
- Revise and exercise the playbook against current network dependencies
- Exercise loss-of-domain and loss-of-email scenarios on a schedule
- Run a tabletop test using only resources available during network isolation
- Establish a secure out-of-band contact and emergency access procedure
Explanation
Correct Answers
D:The exercise exposes dependencies on systems likely to be unavailable during an attack; within the combined response for whether preparation includes out-of-band access, this supplies process validation: the review establishes whether preparation includes out-of-band access so that responsibility and next decisions rest on a recorded result.
E:Separating response communications from affected infrastructure sustains coordination; within the combined response for whether preparation includes out-of-band access, this supplies immediate response coordination: the immediate coordination decision concerns whether preparation includes out-of-band access; it keeps the response process under explicit control.
Incorrect Answers
A:Tested access restores operational capability without relying on compromised identity systems; when judging whether preparation includes out-of-band access, corrective follow-through follows initial protection; this is instead procedural correction.
B:Tested updates restore confidence that specified actions will work; that method could help with whether playbooks match current architecture; the immediate response coordination decision here involves whether preparation includes out-of-band access.
C:Practical drills expose hidden dependencies earlier than a paper review; the requirement concerns whether preparation includes out-of-band access, so prevention cannot replace immediate action.
Question 54
After technical restoration, responders document the weakness exposed by: The SOC calls every ATT&CK technique observed in logs a separate incident and loses the attack narrative. Which long-term control would reduce exposure to this specific pattern?
- Train analysts to separate analytic technique tags from incident identifiers
- Maintain clear mappings between strategic frameworks and tactical procedures
- Build a cohesive intrusion timeline with mapped ATT&CK techniques
- Correlate technique observations by actor activity, time and affected assets
Explanation
Correct Answer
A:Consistent taxonomy prevents misleading case counts; this turns the weakness behind how technique mapping relates to incident grouping into a measurable prevention requirement.
Incorrect Answers
B:Document clarity prevents responders from expecting nonexistent implementation instructions; that method could help with what CSF 2.0 actually organizes; the readiness improvement decision here involves how technique mapping relates to incident grouping.
C:A technique map helps explain behavior without replacing incident evidence; when judging how technique mapping relates to incident grouping, case recovery is not future-risk control; this is instead procedural correction.
D:ATT&CK classifies behavior, while incident scope depends on connected events and impact; for how technique mapping relates to incident grouping, an investigation is not recurrence prevention; readiness improvement remains necessary.
Question 55
Before revising the playbook, the incident manager checks the following: A SIEM identifies a phishing indicator but responders copy it manually between five security products. Which audit, correlation or test best verifies the reported governance weakness?
- Trigger an approved indicator-distribution playbook from the correlated alert
- Measure alert-to-block latency across the ticket and tool audit trails
- Reconcile identity audit events with the playbook's callback and error logs
- Verify each downstream control acknowledged and applied the block
- Use tested SOAR integrations with access-scoped service identities
Explanation
Correct Answer
B:Timestamped actions reveal which manual transfer created the largest exposure window; this provides an auditable basis for the disputed finding: where manual coordination delays indicator response.
Incorrect Answers
A:Automated propagation shortens the delay while maintaining change records; when judging where manual coordination delays indicator response, immediate protection does not substantiate findings; this is instead immediate response coordination.
C:A missing acknowledgement can leave the case stale despite an executed revocation; the activity targets why orchestration status differs from control state; process validation here concerns where manual coordination delays indicator response.
D:Execution evidence distinguishes a submitted workflow from actual protection; the goal is process validation for where manual coordination delays indicator response. Recovery is not factual verification.
E:Controlled integrations reduce transcription errors without granting unnecessary privileges; prevention is not incident verification in the decision about where manual coordination delays indicator response.
Question 56
A post-incident audit examines the following failure mode: Law enforcement requests original disk evidence while the business intends to overwrite the device for restoration. What recurring check or restriction would best address the weakness?
- Define legal-hold and release procedures in incident playbooks
- Restore business operations only from an authorized clean replacement
- Confirm the lawful request, evidence scope and authorized custodian
- Establish data minimization and third-party sharing controls in playbooks
Explanation
Correct Answer
A:Clear handoffs reduce conflict between investigation and service recovery; it closes a repeatable gap revealed by how to reconcile evidence preservation with operational recovery without removing useful monitoring.
Incorrect Answers
B:Separating working systems from retained evidence avoids destroying potentially material data; the case needs readiness improvement addressing how to reconcile evidence preservation with operational recovery; case recovery is not future-risk control.
C:The legal process and collection requirements determine what must be retained; when judging how to reconcile evidence preservation with operational recovery, an investigation is not recurrence prevention; this is instead process validation.
D:Preauthorized paths prevent ad hoc disclosure during emergencies; it is meant to address what authorization governs external evidence sharing, not readiness improvement for how to reconcile evidence preservation with operational recovery.
Question 57
A documented handling problem requires corrective follow-through: A payroll server shows a new administrator login immediately before confidential reports appeared on an unknown share. What is the appropriate procedural remediation for the gap described?
- Correlate privileged sign-in records with file-share audit events
- Suspend the suspect privileged session while preserving its session identifiers
- Revalidate privileged grants and remove unauthorized share access
- Alert on abnormal privileged logins followed by bulk file-share access
- Close the record with corroborating telemetry and a documented disposition
Explanation
Correct Answer
C:Eliminating the access path addresses the control failure before sensitive workflows resume; the correction restores accountability or sequence for whether a security event involved unauthorized access before case sign-off.
Incorrect Answers
A:The joined timeline can connect an identity, access to protected files, and the suspicious destination; verification is not the corrective step in the decision about whether a security event involved unauthorized access.
B:Revoking the active access path limits further disclosure without discarding the account activity already logged; the case needs procedural correction addressing whether a security event involved unauthorized access; temporary protection does not complete correction.
D:A behavioral correlation catches the combined access pattern rather than either event alone; for whether a security event involved unauthorized access, future hardening is not current-state recovery; procedural correction remains necessary.
E:A justified false-positive closure preserves auditability and allows recurrence analysis; the activity targets whether an alert is a confirmed incident; procedural correction here concerns whether a security event involved unauthorized access.
Question 58
Response staff seek a controlled first step after this problem: A compromised application host is still exchanging data with a known command server while forensic acquisition is scheduled. The manager needs a check that verifies the issue AND an immediate controlled assignment or safeguard. Which TWO case-specific steps fulfill those distinct roles? (Choose TWO.)
- Apply egress allowlisting and alert on rare outbound destinations
- Correlate egress flows with process connections to confirm active command traffic
- Remove persistence and validate the host before controlled reintegration
- Remove persistence, rotate compromised credentials and verify clean scanning
- Block the malicious egress path while retaining appropriate forensic access
Explanation
Correct Answers
B:Both data sources link the suspicious endpoint to ongoing outbound communication; within the combined response for which action limits ongoing exfiltration, this supplies process validation: the review establishes which action limits ongoing exfiltration so that responsibility and next decisions rest on a recorded result.
E:Selective isolation stops active communication without deliberately wiping the system; within the combined response for which action limits ongoing exfiltration, this supplies immediate response coordination: the immediate coordination decision concerns which action limits ongoing exfiltration; it keeps the response process under explicit control.
Incorrect Answers
A:Reducing unneeded paths limits future command-and-control options; the goal is immediate response coordination for which action limits ongoing exfiltration. Prevention cannot replace immediate action.
C:Containment alone does not remove the executable or its scheduled startup path; the case needs immediate response coordination addressing which action limits ongoing exfiltration; corrective follow-through follows initial protection.
D:Complete eradication addresses both malware artifacts and associated identity compromise; the relevant condition for that step is whether eradication removed the attack's persistence, which is not shown for which action limits ongoing exfiltration.
Question 59
Before revising the playbook, the incident manager checks the following: Two analysts independently investigate the same suspicious endpoint and each issues conflicting containment instructions. Which audit, correlation or test best verifies the reported governance weakness?
- Audit ticket ownership changes and responder action timestamps
- Compare shift-change tickets against active incident action logs
- Require a named owner and change log for every high-severity incident
- Reconcile both timelines and publish one approved response plan
- Assign a single incident commander and freeze contradictory changes
Explanation
Correct Answer
A:The case history reveals parallel work and the absence of an authoritative incident owner; this provides an auditable basis for the disputed finding: how incident ownership and assignments broke down.
Incorrect Answers
B:Unassigned tasks and incomplete status fields show where ownership information was lost; this serves the missing continuity of incident response, whereas the requested result is process validation involving how incident ownership and assignments broke down.
C:Formal accountability prevents duplicated actions and untraceable decisions; the requirement concerns how incident ownership and assignments broke down, so prevention is not incident verification.
D:A consolidated record restores situational awareness and defines next responsibilities; the goal is process validation for how incident ownership and assignments broke down. Recovery is not factual verification.
E:Central coordination prevents simultaneous actions from damaging the investigation; immediate protection does not substantiate findings in the decision about how incident ownership and assignments broke down.
Question 60
A long-term control assessment uses this recent event: A SOC manager assesses responder performance only by how quickly tickets are closed. Which change provides measurable prevention rather than an emergency workaround?
- Sample fast-closed cases for evidence completeness and recurrence
- Use containment time, detection lag, evidence quality and recurrence together
- Mandate a minimum handoff checklist and acknowledged ownership transfer
- Introduce quality checks and track repeat compromise after closure
Explanation
Correct Answer
B:Balanced metrics discourage speed at the expense of correctness; it closes a repeatable gap revealed by whether speed metrics reward poor incident decisions without removing useful monitoring.
Incorrect Answers
A:Closure time alone cannot establish whether the attack was actually resolved; when judging whether speed metrics reward poor incident decisions, an investigation is not recurrence prevention; this is instead process validation.
C:Standardized continuity reduces delays during overnight escalation; this serves the missing continuity of incident response, whereas the requested result is readiness improvement involving whether speed metrics reward poor incident decisions.
D:Outcome measures reveal cases prematurely marked resolved; the goal is readiness improvement for whether speed metrics reward poor incident decisions. Case recovery is not future-risk control.
