Question 190
The case requires an immediate custody or preservation safeguard: An imaging technician forgets to capture firmware settings on a machine suspected of boot-level tampering. The first response requires a documented observation AND evidence or scene protection. Which TWO case-specific measures address those separate needs? (Choose TWO.)
- Add boot and firmware checks to relevant acquisition playbooks
- Record firmware version, boot order, secure-boot state and configuration
- Collect supported firmware artifacts and storage images as separate evidence
- Exercise VM snapshot collection in the incident response runbook
- Restrict firmware updates or resets pending approved capture
Explanation
Correct Answers
B:Boot behavior can be controlled by firmware data not visible in a normal disk image; within the combined response for which evidence exists outside the main filesystem, this supplies scene or evidence validation: the first responder needs evidence bearing on which evidence exists outside the main filesystem with source and context recorded.
E:Configuration changes could remove indicators and change boot behavior; within the combined response for which evidence exists outside the main filesystem, this supplies immediate evidence protection: the immediate evidence or scene safeguard follows from which evidence exists outside the main filesystem; additional acquisition requires separate authorization.
Incorrect Answers
A:Risk-based collection covers low-level persistence cases; when judging which evidence exists outside the main filesystem, prevention cannot replace immediate action; this is instead custody-procedure prevention.
C:Multiple sources help distinguish disk infection from firmware compromise; the requirement concerns which evidence exists outside the main filesystem, so corrective follow-through follows initial protection.
D:Rehearsal reveals guest-consistency and retention limitations; the other incident centers on whether the snapshot is consistent and authenticated, not this immediate evidence protection question about which evidence exists outside the main filesystem.
Question 191
The first-response lead needs an authorized protection step for this case: A laptop evidence drive is transported without anti-static protection and later fails to mount. Which TWO actions establish relevant evidence and immediately protect the material from further disturbance? (Choose TWO.)
- Train custodians on media-specific packaging and environmental controls
- Dry and stabilize records using approved conservation practice before long-term storage
- Review packaging material, shock exposure and condition at each transfer
- Use unique barcodes and two-person packaging verification
- Secure remaining components in appropriate anti-static and padded packaging
- Document damage and use specialized recovery without altering originals
Explanation
Correct Answers
C:Improper transport can damage hardware and compromise recoverability; within the combined response for whether packaging protected fragile electronic components, this supplies scene or evidence validation: the resulting observation can be checked against the evidentiary question: whether packaging protected fragile electronic components.
E:Physical protection is part of evidence preservation; within the combined response for whether packaging protected fragile electronic components, this supplies immediate evidence protection: the first-response protection addresses whether packaging protected fragile electronic components without prematurely altering the scene.
Incorrect Answers
A:Correct materials reduce avoidable loss during transport; for whether packaging protected fragile electronic components, prevention cannot replace immediate action; immediate evidence protection remains necessary.
B:Preservation choices must not erase markings or provenance; this serves whether packaging will accelerate physical degradation, whereas the requested result is immediate evidence protection involving whether packaging protected fragile electronic components.
D:Dual checks prevent mix-ups across similar devices; this serves whether exhibit identity survives packaging, whereas the requested result is immediate evidence protection involving whether packaging protected fragile electronic components.
F:Condition changes and recovery methods must be disclosed; when judging whether packaging protected fragile electronic components, corrective follow-through follows initial protection; this is instead evidence-handling correction.
Question 192
A long-term control assessment uses this recent event: A first responder reaches an unlocked laptop displaying a suspected extortion note in a busy office. Which change provides measurable prevention rather than an emergency workaround?
- Use a scene documentation checklist with initial-state photographs
- Photograph the screen, cable connections and device position before changing state
- Establish transaction-safe scene isolation procedures for customer terminals
- Acquire authorized volatile data before deciding on power removal
Explanation
Correct Answer
A:Consistent records support later reconstruction and testimony; the control owner can test whether this reduces repeat conditions affecting the original observable state of a live scene.
Incorrect Answers
B:Images preserve transient context that will be altered during collection; an investigation is not recurrence prevention in the decision about the original observable state of a live scene.
C:Prepared replacements avoid pressure to keep compromised devices in use; that method could help with whether the potential scene is still being altered; the custody-procedure prevention decision here involves the original observable state of a live scene.
D:A live machine may hold keys and process artifacts not present on disk; when judging the original observable state of a live scene, case recovery is not future-risk control; this is instead evidence-handling correction.
Question 193
A first responder begins a documented assessment of the following: Investigators need to transport wet paper records found with a compromised access badge. Which initial forensic observation or acquisition check is supported by these facts?
- Record moisture condition and consult qualified conservation procedures
- Include non-electronic evidence specialists in response contacts
- Keep items separated in suitable breathable packaging under expert guidance
- Review packaging material, shock exposure and condition at each transfer
Explanation
Correct Answer
A:Sealing wet paper improperly can cause deterioration or contamination; this informs the initial finding about whether packaging will accelerate physical degradation without unnecessary disturbance of evidence.
Incorrect Answers
B:Mixed physical and digital incidents need appropriate handling expertise; the requirement concerns whether packaging will accelerate physical degradation, so prevention is not incident verification.
C:Material-appropriate preservation protects the original evidence; the goal is scene or evidence validation for whether packaging will accelerate physical degradation. Immediate protection does not substantiate findings.
D:Improper transport can damage hardware and compromise recoverability; the activity targets whether packaging protected fragile electronic components; scene or evidence validation here concerns whether packaging will accelerate physical degradation.
Question 194
The custodian is restoring a defensible collection record following: An investigator ships an exhibit internationally without checking restrictions on sensitive data and custody documentation. What acquisition, packaging, preservation or custody repair is required?
- Record a truthful corrective custody account without backdating signatures
- Preapprove cross-border forensic transfer pathways and contracts
- Hold shipment pending legal and evidence-custodian approval
- Use approved routes with sealed packaging and documented transfers
Explanation
Correct Answer
D:Legitimate movement must maintain both legal compliance and provenance; this correction supports an authenticated evidence trail for whether cross-border handling is authorized before handling is closed.
Incorrect Answers
A:Transparent reconstruction is essential to evidentiary credibility; it is meant to address where chain of custody lost accountability, not evidence-handling correction for whether cross-border handling is authorized.
B:Prepared procedures avoid delays during time-critical investigations; the case needs evidence-handling correction addressing whether cross-border handling is authorized; future hardening is not current-state recovery.
C:Preservation is preferable to an unauthorized international transfer; when judging whether cross-border handling is authorized, temporary protection does not complete correction; this is instead immediate evidence protection.
Question 195
An evidence-quality review identifies the need to correct this problem: A sealed server disk is handed to a courier without any recorded transfer signature. What must be verified before the evidence handling is complete?
- Record a truthful corrective custody account without backdating signatures
- Secure the item and suspend further informal transfers
- Require timestamped signatures at every change of possession
- Use approved routes with sealed packaging and documented transfers
Explanation
Correct Answer
A:Transparent reconstruction is essential to evidentiary credibility; this correction supports an authenticated evidence trail for where chain of custody lost accountability before handling is closed.
Incorrect Answers
B:Controlled custody limits new uncertainty; the requirement concerns where chain of custody lost accountability, so temporary protection does not complete correction.
C:Continuous records establish who controlled the evidence; the goal is evidence-handling correction for where chain of custody lost accountability. Future hardening is not current-state recovery.
D:Legitimate movement must maintain both legal compliance and provenance; the other incident centers on whether cross-border handling is authorized, not this evidence-handling correction question about where chain of custody lost accountability.
Question 196
To prevent the next similar event, analysts review this case: A forensic examiner copies files using an ordinary desktop file manager and unintentionally changes metadata. Which preventive change targets the exact pathway that failed?
- Reacquire with a validated write blocker and record earlier alterations
- Use forensic write protection and operator training for media acquisitions
- Qualify imaging adapters and inspect error reporting during exercises
- Compare source metadata and acquisition logs for unintended writes
Explanation
Correct Answer
B:Controlled tooling reduces accidental modifications; the control owner can test whether this reduces repeat conditions affecting whether the acquisition modified evidence.
Incorrect Answers
A:A defensible process documents limitations rather than hiding them; the case needs custody-procedure prevention addressing whether the acquisition modified evidence; case recovery is not future-risk control.
C:Validated tooling increases repeatability of forensic acquisition; the activity targets whether the acquisition is complete; custody-procedure prevention here concerns whether the acquisition modified evidence.
D:Ordinary file operations can change access timestamps and other properties; the requirement concerns whether the acquisition modified evidence, so an investigation is not recurrence prevention.
Question 197
Before detailed examination, an evidence-preservation decision concerns: A responder plans to capture only the Documents folder from a server suspected of covert persistence. Which TWO actions establish relevant evidence and immediately protect the material from further disturbance? (Choose TWO.)
- Train teams to choose logical versus physical acquisition deliberately
- Identify relevant system partitions, startup entries and deleted-space needs
- Acquire a forensic image or targeted system artifacts that answer the scope question
- Verify the snapshot or exported disks and retain supporting metadata
- Preserve the source drive while a proportionate acquisition plan is approved
Explanation
Correct Answers
B:Persistence may reside outside user files and require broader forensic scope; within the combined response for whether a logical copy covers the suspected artifacts, this supplies scene or evidence validation: the first responder needs evidence bearing on whether a logical copy covers the suspected artifacts with source and context recorded.
E:Prematurely narrowing collection can permanently lose relevant artifacts; within the combined response for whether a logical copy covers the suspected artifacts, this supplies immediate evidence protection: the immediate evidence or scene safeguard follows from whether a logical copy covers the suspected artifacts; additional acquisition requires separate authorization.
Incorrect Answers
A:Method selection should follow the evidentiary question; the goal is immediate evidence protection for whether a logical copy covers the suspected artifacts. Prevention cannot replace immediate action.
C:Collection should cover the suspected behavior and legal authorization; the case needs immediate evidence protection addressing whether a logical copy covers the suspected artifacts; corrective follow-through follows initial protection.
D:Integrity checks and configuration context make virtual evidence usable; this serves whether the snapshot is consistent and authenticated, whereas the requested result is immediate evidence protection involving whether a logical copy covers the suspected artifacts.
Question 198
During lessons learned, the security owner reviews this completed incident: Responders discover a server cabinet unlocked after a possible physical tampering event. Which repeatable safeguard best prevents this failure mode in the future?
- Record exact equipment identifiers and condition before removal
- Teach responders to inventory adjacent non-digital artifacts
- Photograph seals, rack positions, cabling and cabinet access controls
- Require sealed racks and auditable physical access procedures
Explanation
Correct Answer
D:Physical control reduces tampering opportunities and improves traceability; the assurance measure is designed around which physical conditions must be documented, rather than hiding the reported activity.
Incorrect Answers
A:Unique identifiers prevent mix-ups among similar devices; the case needs custody-procedure prevention addressing which physical conditions must be documented; case recovery is not future-risk control.
B:Physical context can be relevant to cyber incident reconstruction; it is meant to address how associated physical context should be preserved, not custody-procedure prevention for which physical conditions must be documented.
C:These details may show unauthorized physical interaction before equipment is moved; for which physical conditions must be documented, an investigation is not recurrence prevention; custody-procedure prevention remains necessary.
Question 199
After technical restoration, responders document the weakness exposed by: A sealed evidence bag is opened for analysis, then returned to storage without a new seal identifier. Which long-term control would reduce exposure to this specific pattern?
- Record examiner, purpose, condition and replacement seal number
- Use evidence check-in forms requiring seal changes and signatures
- Automate hash verification on every evidence repository migration
- Match entry logs against the original seal and examination schedule
Explanation
Correct Answer
B:Complete custody metadata prevents unexplained openings; the control owner can test whether this reduces repeat conditions affecting whether seal integrity can be tracked after examination.
Incorrect Answers
A:Re-sealing history allows later reviewers to understand every opening; for whether seal integrity can be tracked after examination, case recovery is not future-risk control; custody-procedure prevention remains necessary.
C:Continuous integrity checks detect later bit-level changes; it is meant to address whether an archived copy retains byte integrity, not custody-procedure prevention for whether seal integrity can be tracked after examination.
D:Broken seals require a clear documented reason and a new custody sequence; an investigation is not recurrence prevention in the decision about whether seal integrity can be tracked after examination.
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?
- Compare the diagram to a documented room walkthrough and equipment inventory
- Secure and photograph the newly identified access point before manipulation
- Pause evidence removal until all connected media and device identifiers are recorded
- 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.
