ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 7

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?

  1. Sample fast-closed cases for evidence completeness and recurrence
  2. Use containment time, detection lag, evidence quality and recurrence together
  3. Mandate a minimum handoff checklist and acknowledged ownership transfer
  4. 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.

Question 61

A response-governance owner reviews a documented failure: A containment change was implemented on an internet router without notifying the network duty officer and broke partner connectivity. Which audit, correlation or test best verifies the reported governance weakness?

  1. Compare the runbook network map with live segmentation and routing inventory
  2. Predefine emergency network-change authorities and rollback criteria
  3. Activate the emergency change coordination path and assess immediate rollback
  4. Compare the incident change ticket with the designated approval and escalation matrix
  5. Validate the mitigation and partner connectivity before closing the change

Explanation

Correct Answer

D:

The record shows whether emergency authority and network coordination were followed; this provides an auditable basis for the disputed finding: the control approval missing from the change.

Incorrect Answers

A:

Outdated topology can make otherwise sound containment instructions ineffective; this serves whether playbooks match current architecture, whereas the requested result is process validation involving the control approval missing from the change.

B:

A tested authorization path prevents uncontrolled containment disruption; for the control approval missing from the change, prevention is not incident verification; process validation remains necessary.

C:

Controlled action restores oversight while limiting further incident exposure; the requirement concerns the control approval missing from the change, so immediate protection does not substantiate findings.

E:

Both threat containment and service availability must be checked; recovery is not factual verification in the decision about the control approval missing from the change.

Question 62

During lessons learned, the security owner reviews this completed incident: A responder removes one malicious executable but leaves its service configuration and remote credentials active. Which repeatable safeguard best prevents this failure mode in the future?

  1. Track root-cause remediation as a required closure dependency
  2. Make a blameless post-incident review a required high-severity milestone
  3. Remove persistence, rotate compromised credentials and verify clean scanning
  4. Examine service configuration, scheduled starts and account-use records

Explanation

Correct Answer

A:

Technical closure should include all enabling weaknesses, not just file removal; the assurance measure is designed around whether eradication removed the attack's persistence, rather than hiding the reported activity.

Incorrect Answers

B:

Structured learning improves response without punishing accurate reporting; the activity targets what post-incident learning is missing; readiness improvement here concerns whether eradication removed the attack's persistence.

C:

Complete eradication addresses both malware artifacts and associated identity compromise; case recovery is not future-risk control in the decision about whether eradication removed the attack's persistence.

D:

Persistence and stolen credentials can sustain access after one file is deleted; the case needs readiness improvement addressing whether eradication removed the attack's persistence; an investigation is not recurrence prevention.

Question 63

Before revising the playbook, the incident manager checks the following: Two separate departments discover related compromise indicators but use incompatible severity labels. Which targeted review or exercise would most directly validate this process gap?

  1. Map both case records against a common impact-and-urgency matrix
  2. Appoint a cross-functional incident lead and merge correlated scope findings
  3. Reclassify affected cases using the agreed business-impact scale
  4. Review affected data classification together with host criticality and exposure
  5. Publish severity definitions with worked examples and training

Explanation

Correct Answer

A:

Shared criteria permit consistent escalation despite different local terminology; the review establishes how to normalize severity across organizational units so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

B:

One coordinated response reduces contradictory containment measures; the goal is process validation for how to normalize severity across organizational units. Immediate protection does not substantiate findings.

C:

Consistent severity supports defensible reporting across teams; recovery is not factual verification in the decision about how to normalize severity across organizational units.

D:

Business sensitivity can outweigh the number of visibly impacted machines; the relevant condition for that step is whether incident priority reflects business impact, which is not shown for how to normalize severity across organizational units.

E:

Common interpretation reduces repeated classification disputes; when judging how to normalize severity across organizational units, prevention is not incident verification; this is instead readiness improvement.

Question 64

The owner is reconciling responder actions with the approved plan after: A triage analyst has only an IP address from an old NAT gateway log and assigns the incident to the wrong user. Which follow-up would repair the reported response-management failure?

  1. Correct the case attribution and document uncertain mappings
  2. Reconcile data, test dependent services and obtain application-owner acceptance
  3. Pause individual account sanctions until attribution is independently validated
  4. Retain synchronized NAT, DHCP and authentication logs at adequate granularity

Explanation

Correct Answer

A:

Traceable assumptions keep an investigation from building on false identity claims; the correction restores accountability or sequence for how to attribute network activity reliably before case sign-off.

Incorrect Answers

B:

Recovery completes only when usable and trusted business functionality returns; the other incident centers on what recovery validation must include, not this procedural correction question about how to attribute network activity reliably.

C:

Evidence-based escalation avoids disrupting an innocent user's access; the goal is procedural correction for how to attribute network activity reliably. Temporary protection does not complete correction.

D:

Correlated records make future attribution defensible; future hardening is not current-state recovery in the decision about how to attribute network activity reliably.

Question 65

A documented handling problem requires corrective follow-through: Night-shift responders repeatedly miss handoffs for unresolved lateral-movement cases. What is the appropriate procedural remediation for the gap described?

  1. Create an ordered outstanding-actions list with deadlines and evidence links
  2. Use a formal shift handoff with a current incident commander
  3. Reconcile both timelines and publish one approved response plan
  4. Mandate a minimum handoff checklist and acknowledged ownership transfer

Explanation

Correct Answer

A:

A verified handoff enables the incoming team to act without recreating the timeline; the correction restores accountability or sequence for the missing continuity of incident response before case sign-off.

Incorrect Answers

B:

Explicit transfer retains command responsibility while the investigation continues; the case needs procedural correction addressing the missing continuity of incident response; temporary protection does not complete correction.

C:

A consolidated record restores situational awareness and defines next responsibilities; it is meant to address how incident ownership and assignments broke down, not procedural correction for the missing continuity of incident response.

D:

Standardized continuity reduces delays during overnight escalation; for the missing continuity of incident response, future hardening is not current-state recovery; procedural correction remains necessary.

Question 66

A tabletop exercise is being updated using the following real-world failure: A routine vulnerability scan triggered a sensor alarm but no authenticated access or system modification occurred. Which improvement should be tracked through the next control-assurance cycle?

  1. Close the record with corroborating telemetry and a documented disposition
  2. Compare the alert with approved scanner inventory and change-window records
  3. Tune detection exceptions to scanner identity and approved maintenance windows
  4. Alert on abnormal privileged logins followed by bulk file-share access

Explanation

Correct Answer

C:

A narrowly scoped suppression reduces noise without hiding scans from unapproved hosts; the assurance measure is designed around whether an alert is a confirmed incident, rather than hiding the reported activity.

Incorrect Answers

A:

A justified false-positive closure preserves auditability and allows recurrence analysis; when judging whether an alert is a confirmed incident, case recovery is not future-risk control; this is instead procedural correction.

B:

Authorized source and timing explain why the detection may be a benign true positive; for whether an alert is a confirmed incident, an investigation is not recurrence prevention; readiness improvement remains necessary.

D:

A behavioral correlation catches the combined access pattern rather than either event alone; the relevant condition for that step is whether a security event involved unauthorized access, which is not shown for whether an alert is a confirmed incident.

Question 67

During lessons learned, the security owner reviews this completed incident: An automation service account can modify security policies across every tenant despite serving one investigation workspace. Which repeatable safeguard best prevents this failure mode in the future?

  1. Use preproduction simulation and privileged-action guardrails for playbooks
  2. Rotate its secret and reissue role grants after approval testing
  3. Enumerate the integration identity's effective permissions and target scopes
  4. Review SOAR identities and permissions whenever playbooks change

Explanation

Correct Answer

D:

Continuous access governance prevents authorization drift; the control owner can test whether this reduces repeat conditions affecting whether orchestration violates least privilege.

Incorrect Answers

A:

Validation limits damage from poorly scoped automated response; that method could help with whether destructive automation has preservation safeguards; the readiness improvement decision here involves whether orchestration violates least privilege.

B:

Credential replacement and entitlement review restore trust in the integration; the goal is readiness improvement for whether orchestration violates least privilege. Case recovery is not future-risk control.

C:

Excessive cross-tenant grants increase the impact of automation mistakes; an investigation is not recurrence prevention in the decision about whether orchestration violates least privilege.

Question 68

A procedural case requires a near-term protective assignment: A SIEM identifies a phishing indicator but responders copy it manually between five security products. Before long-term corrections, which authorized response action fits the current need?

  1. Measure alert-to-block latency across the ticket and tool audit trails
  2. Trigger an approved indicator-distribution playbook from the correlated alert
  3. Manually verify the session is invalid before triggering another revocation
  4. Verify each downstream control acknowledged and applied the block

Explanation

Correct Answer

B:

Automated propagation shortens the delay while maintaining change records; the immediate coordination decision concerns where manual coordination delays indicator response; it keeps the response process under explicit control.

Incorrect Answers

A:

Timestamped actions reveal which manual transfer created the largest exposure window; the case needs immediate response coordination addressing where manual coordination delays indicator response; investigation alone does not control current conditions.

C:

State checking prevents duplicate disruptive steps and allows safe incident progression; the other incident centers on why orchestration status differs from control state, not this immediate response coordination question about where manual coordination delays indicator response.

D:

Execution evidence distinguishes a submitted workflow from actual protection; the requirement concerns where manual coordination delays indicator response, so corrective follow-through follows initial protection.

Question 69

To prevent the next similar event, analysts review this case: A team deletes suspicious files immediately after receiving a legal request to preserve material from the affected server. Which preventive change targets the exact pathway that failed?

  1. Recover deleted artifacts from approved sources and document irretrievable gaps
  2. Add integrity checks and business-owner sign-off to restoration testing
  3. Halt destructive steps and secure remaining evidence with documented custody
  4. Add evidence-preservation decision points before eradication steps
  5. Compare deletion times with evidence acquisition records and case directives
  6. Include notification SLAs, evidence access and rehearsal requirements in agreements

Explanation

Correct Answer

D:

A documented hold gate prevents remediation from destroying needed artifacts; the assurance measure is designed around why evidence collection must precede destructive remediation, rather than hiding the reported activity.

Incorrect Answers

A:

Transparent reconstruction distinguishes recovered data from missing original evidence; the requirement concerns why evidence collection must precede destructive remediation, so case recovery is not future-risk control.

B:

A functional recovery gate catches failures missed by infrastructure checks; the activity targets what recovery validation must include; readiness improvement here concerns why evidence collection must precede destructive remediation.

C:

Preservation protects evidentiary value while investigators assess what remains; one-time protection is not durable prevention in the decision about why evidence collection must precede destructive remediation.

E:

The timeline can show that potentially relevant bytes were removed before a verified image; when judging why evidence collection must precede destructive remediation, an investigation is not recurrence prevention; this is instead process validation.

F:

Specific obligations reduce dependency ambiguity during incidents; that method could help with whether third-party handoffs are executable; the readiness improvement decision here involves why evidence collection must precede destructive remediation.

Question 70

A response-governance owner reviews a documented failure: Law enforcement requests original disk evidence while the business intends to overwrite the device for restoration. Which targeted review or exercise would most directly validate this process gap?

  1. Confirm the lawful request, evidence scope and authorized custodian
  2. Determine data sensitivity, contractual scope and approved recipients
  3. Define legal-hold and release procedures in incident playbooks
  4. Preserve a verified forensic image and secure the original under chain of custody

Explanation

Correct Answer

A:

The legal process and collection requirements determine what must be retained; the review establishes how to reconcile evidence preservation with operational recovery so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

B:

Evidence sharing can itself create unnecessary exposure when recipient authority is unverified; the relevant condition for that step is what authorization governs external evidence sharing, which is not shown for how to reconcile evidence preservation with operational recovery.

C:

Clear handoffs reduce conflict between investigation and service recovery; prevention is not incident verification in the decision about how to reconcile evidence preservation with operational recovery.

D:

Maintaining evidentiary integrity permits separate operational restoration decisions; the case needs process validation addressing how to reconcile evidence preservation with operational recovery; immediate protection does not substantiate findings.
