ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 23

Question 220

The recurrence-prevention decision is based on this report: An incident involves a shared laboratory where unknown visitors may have handled a suspicious USB drive. What measure strengthens readiness against the observed event?

  1. Use controlled visitor sign-in and removable-media handling protocols
  2. Collect visitor badges, access logs and witness statements for the relevant interval
  3. Label the exhibit with location, collector and first observed condition
  4. Teach note-taking with immutable originals and dated addenda

Explanation

Correct Answer

A:

Better access records strengthen future scene reconstruction; it makes the lesson about who accessed the original evidence part of normal operations.

Incorrect Answers

B:

An access chronology identifies potential handlers and alternative explanations; the goal is custody-procedure prevention for who accessed the original evidence. An investigation is not recurrence prevention.

C:

Context and provenance matter when interpreting later technical findings; case recovery is not future-risk control in the decision about who accessed the original evidence.

D:

Structured documentation reduces unintended reconstruction bias; the relevant condition for that step is which statements are contemporaneous observations, which is not shown for who accessed the original evidence.

Question 221

A long-term control assessment uses this recent event: Several responders entered a restricted office but nobody maintained an access log. Which change provides measurable prevention rather than an emergency workaround?

  1. Interview participants and reconcile badge records with entry times
  2. Establish a controlled entry point and begin logging all further access
  3. Document the original omission and every reconstruction assumption
  4. Assign a scene custodian and maintain entry/exit logs from first contact
  5. Monitor time synchronization status on devices that generate security logs

Explanation

Correct Answer

D:

Explicit responsibility supports reliable custody evidence; this turns the weakness behind whether the scene's integrity can be reconstructed into a measurable prevention requirement.

Incorrect Answers

A:

A reconstructed access list is weaker than contemporaneous logs but still informative; the goal is custody-procedure prevention for whether the scene's integrity can be reconstructed. An investigation is not recurrence prevention.

B:

Immediate perimeter discipline limits additional unexplained changes; one-time protection is not durable prevention in the decision about whether the scene's integrity can be reconstructed.

C:

Transparent gaps are preferable to invented certainty; the case needs custody-procedure prevention addressing whether the scene's integrity can be reconstructed; case recovery is not future-risk control.

E:

Reliable clocks reduce future timeline ambiguity; that method could help with how clock skew affects forensic correlation; the custody-procedure prevention decision here involves whether the scene's integrity can be reconstructed.

Question 222

The incident is resolved, but its root weakness still requires policy attention: A live Linux host is scheduled for shutdown, but investigators need its active connections and processes. What durable process or monitoring change would make a repeat less likely?

  1. Maintain tested live-response toolkits and acquisition procedures
  2. Capture active socket, process and memory state using approved tools
  3. Image persistent storage and document shutdown actions after volatile capture
  4. Require original machine-readable network evidence when available

Explanation

Correct Answer

A:

Prepared collection reduces errors when time is constrained; its effectiveness can be exercised against the warning conditions associated with which artifacts will disappear on shutdown.

Incorrect Answers

B:

Volatile information can expose current sessions and malware that disk imaging misses; the case needs custody-procedure prevention addressing which artifacts will disappear on shutdown; an investigation is not recurrence prevention.

C:

Order-of-volatility handling retains both transient and durable artifacts; when judging which artifacts will disappear on shutdown, case recovery is not future-risk control; this is instead evidence-handling correction.

D:

Complete artifacts support stronger forensic conclusions than pictures alone; this serves what traffic evidence screenshots cannot establish, whereas the requested result is custody-procedure prevention involving which artifacts will disappear on shutdown.

Question 223

A tabletop exercise is being updated using the following real-world failure: A sealed server disk is handed to a courier without any recorded transfer signature. Which improvement should be tracked through the next control-assurance cycle?

  1. Preapprove cross-border forensic transfer pathways and contracts
  2. Require timestamped signatures at every change of possession
  3. Record a truthful corrective custody account without backdating signatures
  4. Identify the last documented holder and reconcile courier tracking records

Explanation

Correct Answer

B:

Continuous records establish who controlled the evidence; the control owner can test whether this reduces repeat conditions affecting where chain of custody lost accountability.

Incorrect Answers

A:

Prepared procedures avoid delays during time-critical investigations; this serves whether cross-border handling is authorized, whereas the requested result is custody-procedure prevention involving where chain of custody lost accountability.

C:

Transparent reconstruction is essential to evidentiary credibility; the case needs custody-procedure prevention addressing where chain of custody lost accountability; case recovery is not future-risk control.

D:

An undocumented handoff creates a custody gap that must be explained; when judging where chain of custody lost accountability, an investigation is not recurrence prevention; this is instead scene or evidence validation.

Question 224

Before any intrusive acquisition, the scene notes state: An investigator collects a cloud audit export but forgets to note the query filters and time zone. Which verification or documentation step is required for the stated evidence uncertainty?

  1. Record firmware version, boot order, secure-boot state and configuration
  2. Use standardized cloud evidence export templates with query provenance
  3. Preserve the exact query, time range, timezone and export job identifier
  4. Stop overwriting the only export and secure the source retention policy

Explanation

Correct Answer

C:

Without collection parameters, missing events cannot be interpreted reliably; the resulting observation can be checked against the evidentiary question: whether the log collection is reproducible.

Incorrect Answers

A:

Boot behavior can be controlled by firmware data not visible in a normal disk image; the activity targets which evidence exists outside the main filesystem; scene or evidence validation here concerns whether the log collection is reproducible.

B:

Consistent metadata makes investigations repeatable; prevention is not incident verification in the decision about whether the log collection is reproducible.

D:

Preservation protects both the current result and ability to re-query; when judging whether the log collection is reproducible, immediate protection does not substantiate findings; this is instead immediate evidence protection.

Question 225

To prevent the next similar event, analysts review this case: A responder takes screenshots of suspicious web traffic but fails to retain packet captures. Which preventive change targets the exact pathway that failed?

  1. Use standardized cloud evidence export templates with query provenance
  2. Hash and archive packet captures with clock and sensor-location notes
  3. Require original machine-readable network evidence when available
  4. Identify the original capture files and full protocol metadata available

Explanation

Correct Answer

C:

Complete artifacts support stronger forensic conclusions than pictures alone; this turns the weakness behind what traffic evidence screenshots cannot establish into a measurable prevention requirement.

Incorrect Answers

A:

Consistent metadata makes investigations repeatable; it is meant to address whether the log collection is reproducible, not custody-procedure prevention for what traffic evidence screenshots cannot establish.

B:

Sensor context explains visibility and timestamp relationships; when judging what traffic evidence screenshots cannot establish, case recovery is not future-risk control; this is instead evidence-handling correction.

D:

Screenshots may omit sequence, headers and payload context needed to validate conclusions; the requirement concerns what traffic evidence screenshots cannot establish, so an investigation is not recurrence prevention.

Question 226

Before completing an evidence transfer, staff must resolve this issue: A laptop evidence drive is transported without anti-static protection and later fails to mount. What must be verified before the evidence handling is complete?

  1. Train custodians on media-specific packaging and environmental controls
  2. Secure remaining components in appropriate anti-static and padded packaging
  3. Re-copy from the verified master and retain transfer audit records
  4. Document damage and use specialized recovery without altering originals

Explanation

Correct Answer

D:

Condition changes and recovery methods must be disclosed; this correction supports an authenticated evidence trail for whether packaging protected fragile electronic components before handling is closed.

Incorrect Answers

A:

Correct materials reduce avoidable loss during transport; for whether packaging protected fragile electronic components, future hardening is not current-state recovery; evidence-handling correction remains necessary.

B:

Physical protection is part of evidence preservation; the requirement concerns whether packaging protected fragile electronic components, so temporary protection does not complete correction.

C:

A controlled retry can resolve corrupted storage or transmission; this serves whether an archived copy retains byte integrity, whereas the requested result is evidence-handling correction involving whether packaging protected fragile electronic components.

Question 227

The initial evidence record needs corroboration after this finding: Investigators find an open notebook with credentials beside a compromised desktop. What case-specific examination makes the evidence record reliable?

  1. Restrict use or movement of the notebook and workstation together
  2. Photograph the notebook's location relative to the workstation
  3. Teach responders to inventory adjacent non-digital artifacts
  4. Package the notebook as a separate labeled exhibit after documentation
  5. Record kiosk time and reference time simultaneously without silently resetting it

Explanation

Correct Answer

B:

Position and visible pages may explain access without requiring casual handling; the first responder needs evidence bearing on how associated physical context should be preserved with source and context recorded.

Incorrect Answers

A:

Protecting both artifacts preserves the relationship of physical and digital evidence; the requirement concerns how associated physical context should be preserved, so immediate protection does not substantiate findings.

C:

Physical context can be relevant to cyber incident reconstruction; prevention is not incident verification in the decision about how associated physical context should be preserved.

D:

Separate tracking protects provenance while maintaining the association; the case needs scene or evidence validation addressing how associated physical context should be preserved; recovery is not factual verification.

E:

The observed offset is necessary to align its artifacts with other logs; that method could help with how clock skew affects forensic correlation; the scene or evidence validation decision here involves how associated physical context should be preserved.

Question 228

An evidence-quality review identifies the need to correct this problem: A responder images a disk through an untested adapter that silently drops read errors. What follow-through step corrects the first-responder evidence gap?

  1. Hash and archive packet captures with clock and sensor-location notes
  2. Reacquire with a validated device and document unreadable regions
  3. Qualify imaging adapters and inspect error reporting during exercises
  4. Set the suspect image aside and preserve the original media

Explanation

Correct Answer

B:

Full logging distinguishes collection limitations from deliberate modification; the custodian can verify that the evidence gap concerning whether the acquisition is complete has been corrected.

Incorrect Answers

A:

Sensor context explains visibility and timestamp relationships; it is meant to address what traffic evidence screenshots cannot establish, not evidence-handling correction for whether the acquisition is complete.

C:

Validated tooling increases repeatability of forensic acquisition; the case needs evidence-handling correction addressing whether the acquisition is complete; future hardening is not current-state recovery.

D:

Avoid relying on a possibly incomplete copy; when judging whether the acquisition is complete, temporary protection does not complete correction; this is instead immediate evidence protection.

Question 229

A responder must safeguard a scene or evidence workflow described as follows: Investigators need to transport wet paper records found with a compromised access badge. How should the responder protect this scene or collection workflow now?

  1. Keep items separated in suitable breathable packaging under expert guidance
  2. Secure remaining components in appropriate anti-static and padded packaging
  3. Include non-electronic evidence specialists in response contacts
  4. Record moisture condition and consult qualified conservation procedures
  5. Apply an approved radio-isolation method that considers power and device behavior
  6. Dry and stabilize records using approved conservation practice before long-term storage

Explanation

Correct Answer

A:

Material-appropriate preservation protects the original evidence; this preserves handling integrity for whether packaging will accelerate physical degradation before detailed collection proceeds.

Incorrect Answers

B:

Physical protection is part of evidence preservation; this serves whether packaging protected fragile electronic components, whereas the requested result is immediate evidence protection involving whether packaging will accelerate physical degradation.

C:

Mixed physical and digital incidents need appropriate handling expertise; the goal is immediate evidence protection for whether packaging will accelerate physical degradation. Prevention cannot replace immediate action.

D:

Sealing wet paper improperly can cause deterioration or contamination; investigation alone does not control current conditions in the decision about whether packaging will accelerate physical degradation.

E:

Proper isolation reduces remote alteration without improvised unsafe modifications; the other incident centers on whether seized devices can receive remote commands, not this immediate evidence protection question about whether packaging will accelerate physical degradation.

F:

Preservation choices must not erase markings or provenance; when judging whether packaging will accelerate physical degradation, corrective follow-through follows initial protection; this is instead evidence-handling correction.

Question 230

Before detailed examination, an evidence-preservation decision concerns: Two sealed evidence bags have identical labels, and the custodian cannot determine which source drive is which. What first-response measure minimizes evidence disturbance under the circumstances?

  1. Use unique barcodes and two-person packaging verification
  2. Stop unsupervised access until the exhibit is resecured
  3. Apply corrected unique identifiers with a documented relabeling history
  4. Quarantine the packages until the identity discrepancy is resolved
  5. Reconcile serial numbers, case inventory and seal records for both packages

Explanation

Correct Answer

D:

Uncertain evidence should not be silently attributed to a device; this preserves handling integrity for whether exhibit identity survives packaging before detailed collection proceeds.

Incorrect Answers

A:

Dual checks prevent mix-ups across similar devices; prevention cannot replace immediate action in the decision about whether exhibit identity survives packaging.

B:

Controlled handling restores accountability following opening; the activity targets whether seal integrity can be tracked after examination; immediate evidence protection here concerns whether exhibit identity survives packaging.

C:

Transparent corrections preserve the chain rather than rewriting it; when judging whether exhibit identity survives packaging, corrective follow-through follows initial protection; this is instead evidence-handling correction.

E:

Ambiguous labels break the reliable link between exhibit and source; the requirement concerns whether exhibit identity survives packaging, so investigation alone does not control current conditions.
