ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 2

Question 10

Before revising the playbook, the incident manager checks the following: An intrusion drill finds that the isolation runbook references network ports moved during last quarter's redesign. Which targeted review or exercise would most directly validate this process gap?

  1. Confirm the correct enforcement point before pushing emergency blocks
  2. Treat infrastructure changes as triggers for playbook maintenance
  3. Run a tabletop test using only resources available during network isolation
  4. Compare the runbook network map with live segmentation and routing inventory

Explanation

Correct Answer

D:

Outdated topology can make otherwise sound containment instructions ineffective; the review establishes whether playbooks match current architecture so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

A:

Targeted network action avoids isolating unrelated services; the requirement concerns whether playbooks match current architecture, so immediate protection does not substantiate findings.

B:

Change-driven review prevents stale emergency instructions; the goal is process validation for whether playbooks match current architecture. Prevention is not incident verification.

C:

The exercise exposes dependencies on systems likely to be unavailable during an attack; it is meant to address whether preparation includes out-of-band access, not process validation for whether playbooks match current architecture.

Question 11

A case commander must regain control of an open handling problem: A monitoring alert is copied into email threads but never receives an incident identifier or accountable owner. Which immediate decision would restore control of the ongoing handling process?

  1. Reconcile all prior messages and artifacts into the case timeline
  2. Reopen the improvement review and assign corrective-action owners
  3. Open a central incident record and assign an authorized handler
  4. Search the ticket queue for an immutable case identifier and assignment history

Explanation

Correct Answer

C:

A single case record makes containment and escalation attributable; the case needs an authorized near-term step for how incident recording supports traceability, with longer-term playbook changes handled separately.

Incorrect Answers

A:

A complete record prevents decisions and evidence references from being lost; corrective follow-through follows initial protection in the decision about how incident recording supports traceability.

B:

A documented follow-up prevents recurring problems from being buried at closure; the relevant condition for that step is what post-incident learning is missing, which is not shown for how incident recording supports traceability.

D:

Unstructured emails do not provide the consistent audit trail needed for response governance; for how incident recording supports traceability, investigation alone does not control current conditions; immediate response coordination remains necessary.

Question 12

For the next control cycle, the responder supplies this incident history: A restored server passes a boot test but its business transactions fail integrity checks. Which ongoing safeguard should be implemented and tested?

  1. Reconcile data, test dependent services and obtain application-owner acceptance
  2. Keep the server in a restricted validation segment until data integrity passes
  3. Compare application transactions against known-good reconciliation results
  4. Add integrity checks and business-owner sign-off to restoration testing
  5. Exercise loss-of-domain and loss-of-email scenarios on a schedule

Explanation

Correct Answer

D:

A functional recovery gate catches failures missed by infrastructure checks; a periodic review of this safeguard can track the risk described by what recovery validation must include.

Incorrect Answers

A:

Recovery completes only when usable and trusted business functionality returns; the goal is readiness improvement for what recovery validation must include. Case recovery is not future-risk control.

B:

Controlled access prevents unreliable service from affecting production users; one-time protection is not durable prevention in the decision about what recovery validation must include.

C:

Boot success does not prove that business data and dependent workflows remain correct; the case needs readiness improvement addressing what recovery validation must include; an investigation is not recurrence prevention.

E:

Practical drills expose hidden dependencies earlier than a paper review; it is meant to address whether preparation includes out-of-band access, not readiness improvement for what recovery validation must include.

Question 13

A tabletop exercise is being updated using the following real-world failure: A containment change was implemented on an internet router without notifying the network duty officer and broke partner connectivity. Which improvement should be tracked through the next control-assurance cycle?

  1. Preassign spokespersons, approval gates and communication templates
  2. Compare the incident change ticket with the designated approval and escalation matrix
  3. Validate the mitigation and partner connectivity before closing the change
  4. Predefine emergency network-change authorities and rollback criteria

Explanation

Correct Answer

D:

A tested authorization path prevents uncontrolled containment disruption; it closes a repeatable gap revealed by the control approval missing from the change without removing useful monitoring.

Incorrect Answers

A:

A rehearsal-tested plan makes crisis messages consistent; the relevant condition for that step is what made external incident messaging inconsistent, which is not shown for the control approval missing from the change.

B:

The record shows whether emergency authority and network coordination were followed; for the control approval missing from the change, an investigation is not recurrence prevention; readiness improvement remains necessary.

C:

Both threat containment and service availability must be checked; the requirement concerns the control approval missing from the change, so case recovery is not future-risk control.

Question 14

The recurrence-prevention decision is based on this report: A vendor asks a responder to forward raw incident logs containing personal identifiers to an unrelated external consultant. What measure strengthens readiness against the observed event?

  1. Establish data minimization and third-party sharing controls in playbooks
  2. Embed jurisdiction-specific privacy triggers in the response notification matrix
  3. Log recipient, purpose, content and secure deletion or retention terms
  4. Determine data sensitivity, contractual scope and approved recipients

Explanation

Correct Answer

A:

Preauthorized paths prevent ad hoc disclosure during emergencies; it makes the lesson about what authorization governs external evidence sharing part of normal operations.

Incorrect Answers

B:

Preplanned legal routing minimizes missed deadlines and unauthorized statements; the activity targets whether notification requirements are factually triggered; readiness improvement here concerns what authorization governs external evidence sharing.

C:

A complete disclosure record supports accountability after the incident; for what authorization governs external evidence sharing, case recovery is not future-risk control; readiness improvement remains necessary.

D:

Evidence sharing can itself create unnecessary exposure when recipient authority is unverified; the requirement concerns what authorization governs external evidence sharing, so an investigation is not recurrence prevention.

Question 15

A case commander must regain control of an open handling problem: A team deletes suspicious files immediately after receiving a legal request to preserve material from the affected server. Which immediate assignment, safeguard or coordination decision is justified?

  1. Recover deleted artifacts from approved sources and document irretrievable gaps
  2. Compare deletion times with evidence acquisition records and case directives
  3. Halt destructive steps and secure remaining evidence with documented custody
  4. Block the malicious egress path while retaining appropriate forensic access

Explanation

Correct Answer

C:

Preservation protects evidentiary value while investigators assess what remains; the immediate coordination decision concerns why evidence collection must precede destructive remediation; it keeps the response process under explicit control.

Incorrect Answers

A:

Transparent reconstruction distinguishes recovered data from missing original evidence; the requirement concerns why evidence collection must precede destructive remediation, so corrective follow-through follows initial protection.

B:

The timeline can show that potentially relevant bytes were removed before a verified image; the goal is immediate response coordination for why evidence collection must precede destructive remediation. Investigation alone does not control current conditions.

D:

Selective isolation stops active communication without deliberately wiping the system; the other incident centers on which action limits ongoing exfiltration, not this immediate response coordination question about why evidence collection must precede destructive remediation.

Question 16

An immediate process decision is needed for the following concern: A service provider receives an alert but its contract lacks clear escalation and evidence-retention responsibilities. What response coordination or restriction step should take priority?

  1. Include notification SLAs, evidence access and rehearsal requirements in agreements
  2. Compare contract clauses, contact trees and tested vendor response procedures
  3. Record shared responsibilities and preserve both parties' case artifacts
  4. Invoke emergency vendor contacts and establish a joint incident coordinator
  5. Establish a secure out-of-band contact and emergency access procedure

Explanation

Correct Answer

D:

Named decision makers enable immediate scope and evidence coordination; this protective or assignment decision directly addresses whether third-party handoffs are executable while response governance is still active.

Incorrect Answers

A:

Specific obligations reduce dependency ambiguity during incidents; the goal is immediate response coordination for whether third-party handoffs are executable. Prevention cannot replace immediate action.

B:

Missing duties can delay notification, collection and containment across boundaries; investigation alone does not control current conditions in the decision about whether third-party handoffs are executable.

C:

A unified timeline supports investigation despite separate infrastructures; the case needs immediate response coordination addressing whether third-party handoffs are executable; corrective follow-through follows initial protection.

E:

Separating response communications from affected infrastructure sustains coordination; the relevant condition for that step is whether preparation includes out-of-band access, which is not shown for whether third-party handoffs are executable.

Question 17

The organization needs to repair the response procedure after: A routine vulnerability scan triggered a sensor alarm but no authenticated access or system modification occurred. Which follow-up would repair the reported response-management failure?

  1. Close the record with corroborating telemetry and a documented disposition
  2. Route the event to documented triage instead of declaring a breach
  3. Tune detection exceptions to scanner identity and approved maintenance windows
  4. Revalidate privileged grants and remove unauthorized share access

Explanation

Correct Answer

A:

A justified false-positive closure preserves auditability and allows recurrence analysis; the correction restores accountability or sequence for whether an alert is a confirmed incident before case sign-off.

Incorrect Answers

B:

Classification prevents unnecessary destructive response while retaining evidence of the observed activity; the requirement concerns whether an alert is a confirmed incident, so temporary protection does not complete correction.

C:

A narrowly scoped suppression reduces noise without hiding scans from unapproved hosts; the goal is procedural correction for whether an alert is a confirmed incident. Future hardening is not current-state recovery.

D:

Eliminating the access path addresses the control failure before sensitive workflows resume; this serves whether a security event involved unauthorized access, whereas the requested result is procedural correction involving whether an alert is a confirmed incident.

Question 18

Before revising the playbook, the incident manager checks the following: An automated credential-revocation workflow succeeded in the identity provider but the ticket still reads pending. Which audit, correlation or test best verifies the reported governance weakness?

  1. Monitor action completion receipts rather than workflow invocation alone
  2. Reconcile identity audit events with the playbook's callback and error logs
  3. Manually verify the session is invalid before triggering another revocation
  4. Measure alert-to-block latency across the ticket and tool audit trails

Explanation

Correct Answer

B:

A missing acknowledgement can leave the case stale despite an executed revocation; this provides an auditable basis for the disputed finding: why orchestration status differs from control state.

Incorrect Answers

A:

End-to-end confirmation catches silent integration and acknowledgement failures; when judging why orchestration status differs from control state, prevention is not incident verification; this is instead readiness improvement.

C:

State checking prevents duplicate disruptive steps and allows safe incident progression; the requirement concerns why orchestration status differs from control state, so immediate protection does not substantiate findings.

D:

Timestamped actions reveal which manual transfer created the largest exposure window; the relevant condition for that step is where manual coordination delays indicator response, which is not shown for why orchestration status differs from control state.

Question 19

A post-incident audit examines the following failure mode: Two separate departments discover related compromise indicators but use incompatible severity labels. What recurring check or restriction would best address the weakness?

  1. Map both case records against a common impact-and-urgency matrix
  2. Publish severity definitions with worked examples and training
  3. Include data sensitivity and regulatory triggers in triage scoring
  4. Reclassify affected cases using the agreed business-impact scale

Explanation

Correct Answer

B:

Common interpretation reduces repeated classification disputes; the assurance measure is designed around how to normalize severity across organizational units, rather than hiding the reported activity.

Incorrect Answers

A:

Shared criteria permit consistent escalation despite different local terminology; an investigation is not recurrence prevention in the decision about how to normalize severity across organizational units.

C:

Impact criteria prevent host-count-only severity mistakes; this serves whether incident priority reflects business impact, whereas the requested result is readiness improvement involving how to normalize severity across organizational units.

D:

Consistent severity supports defensible reporting across teams; for how to normalize severity across organizational units, case recovery is not future-risk control; readiness improvement remains necessary.

Question 20

An immediate process decision is needed for the following concern: A payroll server shows a new administrator login immediately before confidential reports appeared on an unknown share. Before long-term corrections, which authorized response action fits the current need?

  1. Correlate privileged sign-in records with file-share audit events
  2. Revalidate privileged grants and remove unauthorized share access
  3. Route the event to documented triage instead of declaring a breach
  4. Suspend the suspect privileged session while preserving its session identifiers

Explanation

Correct Answer

D:

Revoking the active access path limits further disclosure without discarding the account activity already logged; the immediate coordination decision concerns whether a security event involved unauthorized access; it keeps the response process under explicit control.

Incorrect Answers

A:

The joined timeline can connect an identity, access to protected files, and the suspicious destination; the case needs immediate response coordination addressing whether a security event involved unauthorized access; investigation alone does not control current conditions.

B:

Eliminating the access path addresses the control failure before sensitive workflows resume; when judging whether a security event involved unauthorized access, corrective follow-through follows initial protection; this is instead procedural correction.

C:

Classification prevents unnecessary destructive response while retaining evidence of the observed activity; the other incident centers on whether an alert is a confirmed incident, not this immediate response coordination question about whether a security event involved unauthorized access.
