ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 24

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.

Question 231

The case requires an immediate custody or preservation safeguard: A technician repositions monitor cables while taking photographs of a suspect workstation. How should the responder protect this scene or collection workflow now?

  1. Document all further changes and stop unnecessary repositioning
  2. Compare before-and-after photographs and record the exact cable changes
  3. Create a corrected connection diagram showing original and altered states
  4. Secure and photograph the newly identified access point before manipulation

Explanation

Correct Answer

A:

Disciplined scene control prevents avoidable ambiguity; this preserves handling integrity for whether original connections are known before detailed collection proceeds.

Incorrect Answers

B:

Even minor scene alterations can affect the interpretation of network connections; the requirement concerns whether original connections are known, so investigation alone does not control current conditions.

C:

Separate depictions avoid presenting a reconstructed scene as untouched; the goal is immediate evidence protection for whether original connections are known. Corrective follow-through follows initial protection.

D:

This preserves its position and visible cabling for investigation; the other incident centers on whether the scene diagram accurately describes network context, not this immediate evidence protection question about whether original connections are known.

Question 232

The custodian is restoring a defensible collection record following: A floor plan used for evidence collection omits a wireless access point behind a cabinet. Which authorized evidence-handling correction is most defensible?

  1. Validate scene mapping against a physical walkthrough before exit
  2. Update the diagram with measured locations and identification numbers
  3. Record exact equipment identifiers and condition before removal
  4. Secure and photograph the newly identified access point before manipulation

Explanation

Correct Answer

B:

Corrected scene maps reduce confusion during later analysis; the resulting custody or acquisition record should be tested against whether the scene diagram accurately describes network context.

Incorrect Answers

A:

Cross-checking plans minimizes omitted exhibits; the requirement concerns whether the scene diagram accurately describes network context, so future hardening is not current-state recovery.

C:

Unique identifiers prevent mix-ups among similar devices; that method could help with which physical conditions must be documented; the evidence-handling correction decision here involves whether the scene diagram accurately describes network context.

D:

This preserves its position and visible cabling for investigation; the case needs evidence-handling correction addressing whether the scene diagram accurately describes network context; temporary protection does not complete correction.

Question 233

An evidence-quality review identifies the need to correct this problem: The system clock on a compromised kiosk is seven minutes behind a trusted time source. Which handling correction restores reliability of the evidence record?

  1. Package the notebook as a separate labeled exhibit after documentation
  2. Avoid altering system time before documenting the discrepancy
  3. Normalize event timestamps in analysis while retaining original values
  4. Record kiosk time and reference time simultaneously without silently resetting it
  5. Monitor time synchronization status on devices that generate security logs

Explanation

Correct Answer

C:

Separate raw and adjusted times preserve evidentiary transparency; the resulting custody or acquisition record should be tested against how clock skew affects forensic correlation.

Incorrect Answers

A:

Separate tracking protects provenance while maintaining the association; it is meant to address how associated physical context should be preserved, not evidence-handling correction for how clock skew affects forensic correlation.

B:

A premature correction may obscure how recorded timestamps were generated; when judging how clock skew affects forensic correlation, temporary protection does not complete correction; this is instead immediate evidence protection.

D:

The observed offset is necessary to align its artifacts with other logs; the requirement concerns how clock skew affects forensic correlation, so verification is not the corrective step.

E:

Reliable clocks reduce future timeline ambiguity; the goal is evidence-handling correction for how clock skew affects forensic correlation. Future hardening is not current-state recovery.

Question 234

A forensic responder tests an evidence-handling uncertainty: A responder takes screenshots of suspicious web traffic but fails to retain packet captures. What case-specific examination makes the evidence record reliable?

  1. Identify relevant system partitions, startup entries and deleted-space needs
  2. Preserve original pcap files and associated capture configuration
  3. Identify the original capture files and full protocol metadata available
  4. Require original machine-readable network evidence when available

Explanation

Correct Answer

C:

Screenshots may omit sequence, headers and payload context needed to validate conclusions; the first responder needs evidence bearing on what traffic evidence screenshots cannot establish with source and context recorded.

Incorrect Answers

A:

Persistence may reside outside user files and require broader forensic scope; the activity targets whether a logical copy covers the suspected artifacts; scene or evidence validation here concerns what traffic evidence screenshots cannot establish.

B:

Unaltered packet data supports independent reanalysis; the goal is scene or evidence validation for what traffic evidence screenshots cannot establish. Immediate protection does not substantiate findings.

D:

Complete artifacts support stronger forensic conclusions than pictures alone; the case needs scene or evidence validation addressing what traffic evidence screenshots cannot establish; prevention is not incident verification.

Question 235

The team wants a measurable hardening change following this situation: An imaging technician forgets to capture firmware settings on a machine suspected of boot-level tampering. What improvement best addresses the root weakness in a future incident?

  1. Record firmware version, boot order, secure-boot state and configuration
  2. Add boot and firmware checks to relevant acquisition playbooks
  3. Collect supported firmware artifacts and storage images as separate evidence
  4. Train teams to choose logical versus physical acquisition deliberately

Explanation

Correct Answer

B:

Risk-based collection covers low-level persistence cases; it makes the lesson about which evidence exists outside the main filesystem part of normal operations.

Incorrect Answers

A:

Boot behavior can be controlled by firmware data not visible in a normal disk image; the requirement concerns which evidence exists outside the main filesystem, so an investigation is not recurrence prevention.

C:

Multiple sources help distinguish disk infection from firmware compromise; case recovery is not future-risk control in the decision about which evidence exists outside the main filesystem.

D:

Method selection should follow the evidentiary question; that method could help with whether a logical copy covers the suspected artifacts; the custody-procedure prevention decision here involves which evidence exists outside the main filesystem.

Question 236

The case requires an immediate custody or preservation safeguard: A volatile memory capture tool writes its output to the same nearly full disk being investigated. Which immediate preservation, authorization or scene-control decision is safest?

  1. Avoid a routine power-off until approved live collection decisions are made
  2. Document tool footprint and verify captured memory integrity
  3. Measure target free space and expected image size before execution
  4. Redirect acquisition to a verified external destination under the approved method

Explanation

Correct Answer

D:

External storage reduces additional writes to the evidence disk; the immediate evidence or scene safeguard follows from how the collection method can destroy artifacts; additional acquisition requires separate authorization.

Incorrect Answers

A:

A controlled state decision can preserve decrypted evidence while managing risk; it is meant to address which volatile access material could be lost, not immediate evidence protection for how the collection method can destroy artifacts.

B:

Collection side effects must be recorded even with careful tooling; when judging how the collection method can destroy artifacts, corrective follow-through follows initial protection; this is instead evidence-handling correction.

C:

Writing a memory image locally may overwrite unallocated data or exhaust storage; for how the collection method can destroy artifacts, investigation alone does not control current conditions; immediate evidence protection remains necessary.

Question 237

The first-response lead needs an authorized protection step for this case: A responder records witness recollections days later as though they were observations from the initial visit. What immediate custody or scene safeguard matches this constraint?

  1. Annotate each account with source, time and confidence limitations
  2. Separate time-stamped first-hand notes from later interviews in the case record
  3. Stop editing original notes and append dated clarifications instead
  4. Restrict entry and record who already touched the device

Explanation

Correct Answer

C:

Append-only correction protects the history of the investigation; the immediate evidence or scene safeguard follows from which statements are contemporaneous observations; additional acquisition requires separate authorization.

Incorrect Answers

A:

Clear provenance prevents a memory from being presented as direct observation; the requirement concerns which statements are contemporaneous observations, so corrective follow-through follows initial protection.

B:

Evidence quality depends on preserving when and how each statement arose; the goal is immediate evidence protection for which statements are contemporaneous observations. Investigation alone does not control current conditions.

D:

Access control limits additional contamination of potential evidence; that method could help with the original observable state of a live scene; the immediate evidence protection decision here involves which statements are contemporaneous observations.

Question 238

A long-term control assessment uses this recent event: A responder plans to capture only the Documents folder from a server suspected of covert persistence. Which change provides measurable prevention rather than an emergency workaround?

  1. Identify relevant system partitions, startup entries and deleted-space needs
  2. Train teams to choose logical versus physical acquisition deliberately
  3. Standardize memory acquisition methods using external targets and integrity checks
  4. Preserve the source drive while a proportionate acquisition plan is approved
  5. Acquire a forensic image or targeted system artifacts that answer the scope question

Explanation

Correct Answer

B:

Method selection should follow the evidentiary question; the control owner can test whether this reduces repeat conditions affecting whether a logical copy covers the suspected artifacts.

Incorrect Answers

A:

Persistence may reside outside user files and require broader forensic scope; the goal is custody-procedure prevention for whether a logical copy covers the suspected artifacts. An investigation is not recurrence prevention.

C:

Prepared destinations prevent avoidable evidence alteration; this serves how the collection method can destroy artifacts, whereas the requested result is custody-procedure prevention involving whether a logical copy covers the suspected artifacts.

D:

Prematurely narrowing collection can permanently lose relevant artifacts; when judging whether a logical copy covers the suspected artifacts, one-time protection is not durable prevention; this is instead immediate evidence protection.

E:

Collection should cover the suspected behavior and legal authorization; for whether a logical copy covers the suspected artifacts, case recovery is not future-risk control; custody-procedure prevention remains necessary.

Question 239

A first responder begins a documented assessment of the following: A virtual machine is suspected of compromise and administrators want to copy its virtual disk while it is writing. Which initial forensic observation or acquisition check is supported by these facts?

  1. Identify the original capture files and full protocol metadata available
  2. Exercise VM snapshot collection in the incident response runbook
  3. Review hypervisor snapshot state, guest quiescence and acquisition timestamps
  4. Coordinate a supported snapshot with storage and forensic owners

Explanation

Correct Answer

C:

Copying active files without consistency controls can produce an internally inconsistent image; this informs the initial finding about whether the snapshot is consistent and authenticated without unnecessary disturbance of evidence.

Incorrect Answers

A:

Screenshots may omit sequence, headers and payload context needed to validate conclusions; that method could help with what traffic evidence screenshots cannot establish; the scene or evidence validation decision here involves whether the snapshot is consistent and authenticated.

B:

Rehearsal reveals guest-consistency and retention limitations; the requirement concerns whether the snapshot is consistent and authenticated, so prevention is not incident verification.

D:

Controlled capture limits corruption while maintaining appropriate service continuity; immediate protection does not substantiate findings in the decision about whether the snapshot is consistent and authenticated.

Question 240

The case requires an immediate custody or preservation safeguard: An evidence vault stores collected phones beside powered-on radios that may communicate with them. Which protective evidence-handling step should precede detailed acquisition?

  1. Verify preservation state and document any network exposure after seizure
  2. Apply an approved radio-isolation method that considers power and device behavior
  3. Restrict analytical use of the new copy until verification completes
  4. Inspect device state, radio isolation measures and chain records

Explanation

Correct Answer

B:

Proper isolation reduces remote alteration without improvised unsafe modifications; the first-response protection addresses whether seized devices can receive remote commands without prematurely altering the scene.

Incorrect Answers

A:

A clear record identifies possible changes to phone evidence; the goal is immediate evidence protection for whether seized devices can receive remote commands. Corrective follow-through follows initial protection.

C:

A suspect transfer should not be promoted as a trusted master; that method could help with whether an archived copy retains byte integrity; the immediate evidence protection decision here involves whether seized devices can receive remote commands.

D:

Uncontrolled connectivity may permit new data, wipes or notifications; when judging whether seized devices can receive remote commands, investigation alone does not control current conditions; this is instead scene or evidence validation.
