ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 14

Question 130

A case commander must regain control of an open handling problem: An alert on a production database has high confidence but the scope is unknown and the assigned analyst wants to close it. Which immediate decision would restore control of the ongoing handling process?

  1. Record the final validated scope, disposition and decision rationale
  2. Pause individual account sanctions until attribution is independently validated
  3. Check alert provenance, related events and the database's business criticality
  4. Escalate the case for scoped investigation under the critical-asset rule

Explanation

Correct Answer

D:

Preserving an active investigation prevents premature closure of a high-impact event; the case needs an authorized near-term step for what triage must establish before closure, with longer-term playbook changes handled separately.

Incorrect Answers

A:

Closure requires corroborating evidence and documented review; corrective follow-through follows initial protection in the decision about what triage must establish before closure.

B:

Evidence-based escalation avoids disrupting an innocent user's access; it is meant to address how to attribute network activity reliably, not immediate response coordination for what triage must establish before closure.

C:

Severity and scope cannot be inferred solely from a detector confidence score; when judging what triage must establish before closure, investigation alone does not control current conditions; this is instead process validation.

Question 131

A response-governance owner reviews a documented failure: An incident spans EU customer records and an offshore vendor, but the runbook assumes one universal disclosure deadline. Which targeted review or exercise would most directly validate this process gap?

  1. Map affected data subjects, controllers, processors and relevant jurisdictions
  2. Maintain a reviewed jurisdiction-and-contract notification register
  3. Establish data categories, affected jurisdictions, certainty and exposure timeline
  4. Engage the designated privacy lead for jurisdiction-specific deadlines

Explanation

Correct Answer

A:

Obligations can differ by role, event, and applicable law; the review establishes which legal requirements govern notification timing so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

B:

Legal and vendor requirements can be checked rapidly during an incident; the goal is process validation for which legal requirements govern notification timing. Prevention is not incident verification.

C:

Applicable notice rules depend on governing law and the actual nature of the breach; this serves whether notification requirements are factually triggered, whereas the requested result is process validation involving which legal requirements govern notification timing.

D:

Correct routing prevents imposing a generic timeline on every legal regime; the case needs process validation addressing which legal requirements govern notification timing; immediate protection does not substantiate findings.

Question 132

A tabletop exercise is being updated using the following real-world failure: A compromised application host is still exchanging data with a known command server while forensic acquisition is scheduled. Which improvement should be tracked through the next control-assurance cycle?

  1. Remove persistence and validate the host before controlled reintegration
  2. Correlate egress flows with process connections to confirm active command traffic
  3. Apply egress allowlisting and alert on rare outbound destinations
  4. Add integrity checks and business-owner sign-off to restoration testing

Explanation

Correct Answer

C:

Reducing unneeded paths limits future command-and-control options; the assurance measure is designed around which action limits ongoing exfiltration, rather than hiding the reported activity.

Incorrect Answers

A:

Containment alone does not remove the executable or its scheduled startup path; when judging which action limits ongoing exfiltration, case recovery is not future-risk control; this is instead procedural correction.

B:

Both data sources link the suspicious endpoint to ongoing outbound communication; for which action limits ongoing exfiltration, an investigation is not recurrence prevention; readiness improvement remains necessary.

D:

A functional recovery gate catches failures missed by infrastructure checks; the other incident centers on what recovery validation must include, not this readiness improvement question about which action limits ongoing exfiltration.

Question 133

The case requires an immediate custody or preservation safeguard: A responder takes screenshots of suspicious web traffic but fails to retain packet captures. How should the responder protect this scene or collection workflow now?

  1. Identify the original capture files and full protocol metadata available
  2. Require original machine-readable network evidence when available
  3. Preserve original pcap files and associated capture configuration
  4. Hash and archive packet captures with clock and sensor-location notes
  5. Set the suspect image aside and preserve the original media

Explanation

Correct Answer

C:

Unaltered packet data supports independent reanalysis; this preserves handling integrity for what traffic evidence screenshots cannot establish before detailed collection proceeds.

Incorrect Answers

A:

Screenshots may omit sequence, headers and payload context needed to validate conclusions; for what traffic evidence screenshots cannot establish, investigation alone does not control current conditions; immediate evidence protection remains necessary.

B:

Complete artifacts support stronger forensic conclusions than pictures alone; the requirement concerns what traffic evidence screenshots cannot establish, so prevention cannot replace immediate action.

D:

Sensor context explains visibility and timestamp relationships; corrective follow-through follows initial protection in the decision about what traffic evidence screenshots cannot establish.

E:

Avoid relying on a possibly incomplete copy; the other incident centers on whether the acquisition is complete, not this immediate evidence protection question about what traffic evidence screenshots cannot establish.

Question 134

An improvement plan must address recurrence after this case: Two sealed evidence bags have identical labels, and the custodian cannot determine which source drive is which. What should the owner add to the normal control review to reduce recurrence?

  1. Use unique barcodes and two-person packaging verification
  2. Use evidence check-in forms requiring seal changes and signatures
  3. Reconcile serial numbers, case inventory and seal records for both packages
  4. Apply corrected unique identifiers with a documented relabeling history

Explanation

Correct Answer

A:

Dual checks prevent mix-ups across similar devices; it makes the lesson about whether exhibit identity survives packaging part of normal operations.

Incorrect Answers

B:

Complete custody metadata prevents unexplained openings; the activity targets whether seal integrity can be tracked after examination; custody-procedure prevention here concerns whether exhibit identity survives packaging.

C:

Ambiguous labels break the reliable link between exhibit and source; when judging whether exhibit identity survives packaging, an investigation is not recurrence prevention; this is instead scene or evidence validation.

D:

Transparent corrections preserve the chain rather than rewriting it; for whether exhibit identity survives packaging, case recovery is not future-risk control; custody-procedure prevention remains necessary.

Question 135

After initial scene control, the chain-of-custody owner reviews: Investigators find an open notebook with credentials beside a compromised desktop. What acquisition, packaging, preservation or custody repair is required?

  1. Package the notebook as a separate labeled exhibit after documentation
  2. Update the diagram with measured locations and identification numbers
  3. Teach responders to inventory adjacent non-digital artifacts
  4. Restrict use or movement of the notebook and workstation together

Explanation

Correct Answer

A:

Separate tracking protects provenance while maintaining the association; this correction supports an authenticated evidence trail for how associated physical context should be preserved before handling is closed.

Incorrect Answers

B:

Corrected scene maps reduce confusion during later analysis; the relevant condition for that step is whether the scene diagram accurately describes network context, which is not shown for how associated physical context should be preserved.

C:

Physical context can be relevant to cyber incident reconstruction; when judging how associated physical context should be preserved, future hardening is not current-state recovery; this is instead custody-procedure prevention.

D:

Protecting both artifacts preserves the relationship of physical and digital evidence; for how associated physical context should be preserved, temporary protection does not complete correction; evidence-handling correction remains necessary.

Question 136

A first responder begins a documented assessment of the following: A workstation is on a public-facing counter and customers keep using it after a skimmer alert. Which verification or documentation step is required for the stated evidence uncertainty?

  1. Image relevant storage and preserve peripherals as separate exhibits
  2. Take the terminal out of service through an authorized business process
  3. Photograph the screen, cable connections and device position before changing state
  4. Record user activity, physical attachments and the current system state
  5. Establish transaction-safe scene isolation procedures for customer terminals

Explanation

Correct Answer

D:

Continuing interaction can modify artifacts and confuse timelines; the resulting observation can be checked against the evidentiary question: whether the potential scene is still being altered.

Incorrect Answers

A:

A complete collection can connect the software findings with attached hardware; the goal is scene or evidence validation for whether the potential scene is still being altered. Recovery is not factual verification.

B:

Preventing access limits additional transactions and evidence contamination; immediate protection does not substantiate findings in the decision about whether the potential scene is still being altered.

C:

Images preserve transient context that will be altered during collection; the activity targets the original observable state of a live scene; scene or evidence validation here concerns whether the potential scene is still being altered.

E:

Prepared replacements avoid pressure to keep compromised devices in use; for whether the potential scene is still being altered, prevention is not incident verification; scene or evidence validation remains necessary.

Question 137

The case requires an immediate custody or preservation safeguard: A virtual machine is suspected of compromise and administrators want to copy its virtual disk while it is writing. How should the responder protect this scene or collection workflow now?

  1. Review hypervisor snapshot state, guest quiescence and acquisition timestamps
  2. Coordinate a supported snapshot with storage and forensic owners
  3. Verify the snapshot or exported disks and retain supporting metadata
  4. Restrict firmware updates or resets pending approved capture

Explanation

Correct Answer

B:

Controlled capture limits corruption while maintaining appropriate service continuity; this preserves handling integrity for whether the snapshot is consistent and authenticated before detailed collection proceeds.

Incorrect Answers

A:

Copying active files without consistency controls can produce an internally inconsistent image; for whether the snapshot is consistent and authenticated, investigation alone does not control current conditions; immediate evidence protection remains necessary.

C:

Integrity checks and configuration context make virtual evidence usable; the goal is immediate evidence protection for whether the snapshot is consistent and authenticated. Corrective follow-through follows initial protection.

D:

Configuration changes could remove indicators and change boot behavior; the activity targets which evidence exists outside the main filesystem; immediate evidence protection here concerns whether the snapshot is consistent and authenticated.

Question 138

The recurrence-prevention decision is based on this report: A manager wants an untrained technician to investigate a suspect phone while it remains connected to corporate accounts. What measure strengthens readiness against the observed event?

  1. Verify responder authority, scope and mobile-forensic capability
  2. Include electrical and environmental hazards in first-responder training
  3. Perform an approved mobile acquisition with contemporaneous notes
  4. Train frontline staff to secure devices rather than search through them

Explanation

Correct Answer

D:

Defined role boundaries reduce accidental data alteration; it makes the lesson about whether a collector is authorized and competent part of normal operations.

Incorrect Answers

A:

A lawful and defensible acquisition requires appropriate authorization and technique; the requirement concerns whether a collector is authorized and competent, so an investigation is not recurrence prevention.

B:

Digital investigators need safe escalation paths for unsafe scenes; this serves whether immediate physical safety is assured, whereas the requested result is custody-procedure prevention involving whether a collector is authorized and competent.

C:

Controlled collection preserves tool settings, timestamps and limitations; case recovery is not future-risk control in the decision about whether a collector is authorized and competent.

Question 139

A forensic responder tests an evidence-handling uncertainty: A responder photographs an endpoint but omits the serial number and installed external media. What case-specific examination makes the evidence record reliable?

  1. Compare image metadata, inventory records and device markings
  2. Compare before-and-after photographs and record the exact cable changes
  3. Pause evidence removal until all connected media and device identifiers are recorded
  4. Use standard scene forms that require identifiers and attached-device fields

Explanation

Correct Answer

A:

A device description without distinguishing identifiers risks misattribution; the first responder needs evidence bearing on how an exhibit is uniquely identified with source and context recorded.

Incorrect Answers

B:

Even minor scene alterations can affect the interpretation of network connections; the relevant condition for that step is whether original connections are known, which is not shown for how an exhibit is uniquely identified.

C:

Scene completeness should be established before separating components; immediate protection does not substantiate findings in the decision about how an exhibit is uniquely identified.

D:

Mandatory fields prevent common documentation omissions; the case needs scene or evidence validation addressing how an exhibit is uniquely identified; prevention is not incident verification.

Question 140

Before completing an evidence transfer, staff must resolve this issue: Responders discover a server cabinet unlocked after a possible physical tampering event. What follow-through step corrects the first-responder evidence gap?

  1. Control the room perimeter and maintain a scene-entry log
  2. Record exact equipment identifiers and condition before removal
  3. Require sealed racks and auditable physical access procedures
  4. Document the original omission and every reconstruction assumption

Explanation

Correct Answer

B:

Unique identifiers prevent mix-ups among similar devices; the custodian can verify that the evidence gap concerning which physical conditions must be documented has been corrected.

Incorrect Answers

A:

Documented access helps distinguish responders from potential suspects; the goal is evidence-handling correction for which physical conditions must be documented. Temporary protection does not complete correction.

C:

Physical control reduces tampering opportunities and improves traceability; the case needs evidence-handling correction addressing which physical conditions must be documented; future hardening is not current-state recovery.

D:

Transparent gaps are preferable to invented certainty; that method could help with whether the scene's integrity can be reconstructed; the evidence-handling correction decision here involves which physical conditions must be documented.
