ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 21

Question 200

The first-response lead needs an authorized protection step for this case: A floor plan used for evidence collection omits a wireless access point behind a cabinet. What first-response measure minimizes evidence disturbance under the circumstances?

  1. Compare the diagram to a documented room walkthrough and equipment inventory
  2. Secure and photograph the newly identified access point before manipulation
  3. Pause evidence removal until all connected media and device identifiers are recorded
  4. Update the diagram with measured locations and identification numbers

Explanation

Correct Answer

B:

This preserves its position and visible cabling for investigation; this preserves handling integrity for whether the scene diagram accurately describes network context before detailed collection proceeds.

Incorrect Answers

A:

A missing device may explain connectivity and attack reachability; investigation alone does not control current conditions in the decision about whether the scene diagram accurately describes network context.

C:

Scene completeness should be established before separating components; that method could help with how an exhibit is uniquely identified; the immediate evidence protection decision here involves whether the scene diagram accurately describes network context.

D:

Corrected scene maps reduce confusion during later analysis; for whether the scene diagram accurately describes network context, corrective follow-through follows initial protection; immediate evidence protection remains necessary.

Question 201

A forensic responder tests an evidence-handling uncertainty: Responders discover a server cabinet unlocked after a possible physical tampering event. What case-specific examination makes the evidence record reliable?

  1. Require sealed racks and auditable physical access procedures
  2. Control the room perimeter and maintain a scene-entry log
  3. Photograph seals, rack positions, cabling and cabinet access controls
  4. Photograph the notebook's location relative to the workstation

Explanation

Correct Answer

C:

These details may show unauthorized physical interaction before equipment is moved; the first responder needs evidence bearing on which physical conditions must be documented with source and context recorded.

Incorrect Answers

A:

Physical control reduces tampering opportunities and improves traceability; the requirement concerns which physical conditions must be documented, so prevention is not incident verification.

B:

Documented access helps distinguish responders from potential suspects; the goal is scene or evidence validation for which physical conditions must be documented. Immediate protection does not substantiate findings.

D:

Position and visible pages may explain access without requiring casual handling; the activity targets how associated physical context should be preserved; scene or evidence validation here concerns which physical conditions must be documented.

Question 202

Before detailed examination, an evidence-preservation decision concerns: A responder finds an encrypted laptop that is currently logged in and has a mounted decrypted volume. Which controlled first action preserves the relevant evidence and authority?

  1. Delay shutdown briefly under approved risk controls while collection completes
  2. Avoid a routine power-off until approved live collection decisions are made
  3. Document mounted volumes and capture authorized memory and key context
  4. Acquire relevant plaintext data with authorized methods and verify copies

Explanation

Correct Answer

B:

A controlled state decision can preserve decrypted evidence while managing risk; the first-response protection addresses which volatile access material could be lost without prematurely altering the scene.

Incorrect Answers

A:

Authorized sequencing balances continued compromise risk against evidence loss; the other incident centers on which artifacts will disappear on shutdown, not this immediate evidence protection question about which volatile access material could be lost.

C:

Powered-off encryption may block later access to a currently unlocked device; the requirement concerns which volatile access material could be lost, so investigation alone does not control current conditions.

D:

Working access may enable defensible acquisition without bypass attempts; the goal is immediate evidence protection for which volatile access material could be lost. Corrective follow-through follows initial protection.

Question 203

After technical restoration, responders document the weakness exposed by: An investigator ships an exhibit internationally without checking restrictions on sensitive data and custody documentation. Which long-term control would reduce exposure to this specific pattern?

  1. Identify applicable data-transfer restrictions, legal authority and shipping custody terms
  2. Maintain tested mobile-device isolation storage and handling methods
  3. Preapprove cross-border forensic transfer pathways and contracts
  4. Use approved routes with sealed packaging and documented transfers

Explanation

Correct Answer

C:

Prepared procedures avoid delays during time-critical investigations; the control owner can test whether this reduces repeat conditions affecting whether cross-border handling is authorized.

Incorrect Answers

A:

Physical shipment may trigger privacy, customs and contractual obligations; for whether cross-border handling is authorized, an investigation is not recurrence prevention; custody-procedure prevention remains necessary.

B:

Equipment readiness prevents improvised collection errors; this serves whether seized devices can receive remote commands, whereas the requested result is custody-procedure prevention involving whether cross-border handling is authorized.

D:

Legitimate movement must maintain both legal compliance and provenance; case recovery is not future-risk control in the decision about whether cross-border handling is authorized.

Question 204

A control owner is preparing preventive actions after observing: A virtual machine is suspected of compromise and administrators want to copy its virtual disk while it is writing. What tested hardening or process measure follows from the lessons learned?

  1. Exercise VM snapshot collection in the incident response runbook
  2. Verify the snapshot or exported disks and retain supporting metadata
  3. Review hypervisor snapshot state, guest quiescence and acquisition timestamps
  4. Train teams to choose logical versus physical acquisition deliberately

Explanation

Correct Answer

A:

Rehearsal reveals guest-consistency and retention limitations; the ongoing control is targeted at whether the snapshot is consistent and authenticated, rather than a one-time emergency fix.

Incorrect Answers

B:

Integrity checks and configuration context make virtual evidence usable; for whether the snapshot is consistent and authenticated, case recovery is not future-risk control; custody-procedure prevention remains necessary.

C:

Copying active files without consistency controls can produce an internally inconsistent image; the requirement concerns whether the snapshot is consistent and authenticated, so an investigation is not recurrence prevention.

D:

Method selection should follow the evidentiary question; the relevant condition for that step is whether a logical copy covers the suspected artifacts, which is not shown for whether the snapshot is consistent and authenticated.

Question 205

After initial scene control, the chain-of-custody owner reviews: A facility camera captured equipment removal but its footage retention is only twenty-four hours. What acquisition, packaging, preservation or custody repair is required?

  1. Confirm recording coverage and preservation deadline with the camera custodian
  2. Normalize event timestamps in analysis while retaining original values
  3. Hash the exported recording and record export settings and custodian
  4. Request an authorized export and suspend scheduled overwrite of relevant footage
  5. Add short-lived physical security feeds to immediate evidence-preservation checklists

Explanation

Correct Answer

C:

Integrity and provenance allow later verification of the digital video; this correction supports an authenticated evidence trail for what time-sensitive contextual evidence exists before handling is closed.

Incorrect Answers

A:

Short retention makes delay a direct threat to evidence availability; verification is not the corrective step in the decision about what time-sensitive contextual evidence exists.

B:

Separate raw and adjusted times preserve evidentiary transparency; the relevant condition for that step is how clock skew affects forensic correlation, which is not shown for what time-sensitive contextual evidence exists.

D:

Preserving a copy protects the incident timeline without altering source devices unnecessarily; for what time-sensitive contextual evidence exists, temporary protection does not complete correction; evidence-handling correction remains necessary.

E:

Early coordination prevents avoidable footage loss; the requirement concerns what time-sensitive contextual evidence exists, so future hardening is not current-state recovery.

Question 206

Before completing an evidence transfer, staff must resolve this issue: An imaging technician forgets to capture firmware settings on a machine suspected of boot-level tampering. What must be verified before the evidence handling is complete?

  1. Collect supported firmware artifacts and storage images as separate evidence
  2. Document tool footprint and verify captured memory integrity
  3. Add boot and firmware checks to relevant acquisition playbooks
  4. Restrict firmware updates or resets pending approved capture

Explanation

Correct Answer

A:

Multiple sources help distinguish disk infection from firmware compromise; this correction supports an authenticated evidence trail for which evidence exists outside the main filesystem before handling is closed.

Incorrect Answers

B:

Collection side effects must be recorded even with careful tooling; the other incident centers on how the collection method can destroy artifacts, not this evidence-handling correction question about which evidence exists outside the main filesystem.

C:

Risk-based collection covers low-level persistence cases; the goal is evidence-handling correction for which evidence exists outside the main filesystem. Future hardening is not current-state recovery.

D:

Configuration changes could remove indicators and change boot behavior; temporary protection does not complete correction in the decision about which evidence exists outside the main filesystem.

Question 207

The initial evidence record needs corroboration after this finding: A responder records witness recollections days later as though they were observations from the initial visit. What case-specific examination makes the evidence record reliable?

  1. Teach note-taking with immutable originals and dated addenda
  2. Verify responder authority, scope and mobile-forensic capability
  3. Separate time-stamped first-hand notes from later interviews in the case record
  4. Stop editing original notes and append dated clarifications instead

Explanation

Correct Answer

C:

Evidence quality depends on preserving when and how each statement arose; the first responder needs evidence bearing on which statements are contemporaneous observations with source and context recorded.

Incorrect Answers

A:

Structured documentation reduces unintended reconstruction bias; the requirement concerns which statements are contemporaneous observations, so prevention is not incident verification.

B:

A lawful and defensible acquisition requires appropriate authorization and technique; the other incident centers on whether a collector is authorized and competent, not this scene or evidence validation question about which statements are contemporaneous observations.

D:

Append-only correction protects the history of the investigation; the case needs scene or evidence validation addressing which statements are contemporaneous observations; immediate protection does not substantiate findings.

Question 208

An evidence-quality review identifies the need to correct this problem: A responder plans to capture only the Documents folder from a server suspected of covert persistence. What follow-through step corrects the first-responder evidence gap?

  1. Train teams to choose logical versus physical acquisition deliberately
  2. Acquire relevant plaintext data with authorized methods and verify copies
  3. Preserve the source drive while a proportionate acquisition plan is approved
  4. Acquire a forensic image or targeted system artifacts that answer the scope question

Explanation

Correct Answer

D:

Collection should cover the suspected behavior and legal authorization; the custodian can verify that the evidence gap concerning whether a logical copy covers the suspected artifacts has been corrected.

Incorrect Answers

A:

Method selection should follow the evidentiary question; the goal is evidence-handling correction for whether a logical copy covers the suspected artifacts. Future hardening is not current-state recovery.

B:

Working access may enable defensible acquisition without bypass attempts; the activity targets which volatile access material could be lost; evidence-handling correction here concerns whether a logical copy covers the suspected artifacts.

C:

Prematurely narrowing collection can permanently lose relevant artifacts; the case needs evidence-handling correction addressing whether a logical copy covers the suspected artifacts; temporary protection does not complete correction.

Question 209

A forensic responder tests an evidence-handling uncertainty: A volatile memory capture tool writes its output to the same nearly full disk being investigated. What case-specific examination makes the evidence record reliable?

  1. Measure target free space and expected image size before execution
  2. Document tool footprint and verify captured memory integrity
  3. Redirect acquisition to a verified external destination under the approved method
  4. Document mounted volumes and capture authorized memory and key context
  5. Standardize memory acquisition methods using external targets and integrity checks

Explanation

Correct Answer

A:

Writing a memory image locally may overwrite unallocated data or exhaust storage; the first responder needs evidence bearing on how the collection method can destroy artifacts with source and context recorded.

Incorrect Answers

B:

Collection side effects must be recorded even with careful tooling; the goal is scene or evidence validation for how the collection method can destroy artifacts. Recovery is not factual verification.

C:

External storage reduces additional writes to the evidence disk; immediate protection does not substantiate findings in the decision about how the collection method can destroy artifacts.

D:

Powered-off encryption may block later access to a currently unlocked device; it is meant to address which volatile access material could be lost, not scene or evidence validation for how the collection method can destroy artifacts.

E:

Prepared destinations prevent avoidable evidence alteration; when judging how the collection method can destroy artifacts, prevention is not incident verification; this is instead custody-procedure prevention.

Question 210

Before detailed examination, an evidence-preservation decision concerns: A USB drive was acquired bit for bit, but the stored image cannot be matched to the source. What immediate custody or scene safeguard matches this constraint?

  1. Quarantine the unverified image from downstream conclusions until checked
  2. Calculate and compare cryptographic hashes for source and forensic image
  3. Preserve the source drive while a proportionate acquisition plan is approved
  4. Repeat acquisition or explain verification failure with full records

Explanation

Correct Answer

A:

Analysts should not treat an uncertain copy as authoritative evidence; the immediate evidence or scene safeguard follows from whether evidence integrity is demonstrable; additional acquisition requires separate authorization.

Incorrect Answers

B:

Matching digests support that the copied bytes are unchanged within hashing assumptions; the goal is immediate evidence protection for whether evidence integrity is demonstrable. Investigation alone does not control current conditions.

C:

Prematurely narrowing collection can permanently lose relevant artifacts; that method could help with whether a logical copy covers the suspected artifacts; the immediate evidence protection decision here involves whether evidence integrity is demonstrable.

D:

A new verified copy may repair the gap if the source remains available; the case needs immediate evidence protection addressing whether evidence integrity is demonstrable; corrective follow-through follows initial protection.
