ACFE CFE - Investigation (Certified Fraud Examiner - Investigation) Practice Test 55

Question 540

A witness supplies images of alleged bribery messages without underlying conversation data. Which investigative method is best suited to verify the authenticity of a chat screenshot from a phone?

  1. Seek authorized original app data and context where feasible
  2. Assess precision, timestamp, source, and device attribution
  3. Use trained procedures to assess isolation, power, and volatile state
  4. Determine legal authority and practical acquisition options first
  5. Compare authenticated versions and edit timestamps
  6. Image the media through a controlled forensic workflow

Explanation

Correct Answer

A:

Screenshots can be edited or selectively cropped. Native metadata and independent accounts improve reliability.

Incorrect Answers

B:

Location services have accuracy limits; that is the consideration when a team tries to interpret mobile location data responsibly. Correlate the reading with account activity, device ownership, time accuracy, and independent sources; the record instead calls for an action that would verify the authenticity of a chat screenshot from a phone.

C:

Remote connectivity can change or delete evidence, but powering down may also lose data; that is the consideration when a team tries to preserve device state at seizure. The choice should be documented by qualified personnel; it is not a substitute for a step that would verify the authenticity of a chat screenshot from a phone.

D:

Personal-device ownership and encryption complicate access; this responds to a different operational need to plan acquisition of a locked smartphone. Forensic tools cannot bypass the need for lawful permission; it serves another purpose, not the immediate need to verify the authenticity of a chat screenshot from a phone.

E:

Version differences can reveal changed values and timing; this is primarily relevant when the objective is to reconstruct file version history after a disputed edit. The actor behind each change may still need audit corroboration; the examiner still needs to verify the authenticity of a chat screenshot from a phone.

F:

A normal file-browser view may write metadata or omit deleted information; it protects the separate goal to acquire removable media without changing it. Acquisition should preserve source integrity; the priority under these facts is to verify the authenticity of a chat screenshot from a phone.

Question 541

A suspect claims a vendor-reconciliation workbook never existed, but backup logs show a prior file. Which procedure would best allow investigators to look for deleted spreadsheet remnants?

  1. Compare authenticated versions and edit timestamps
  2. Examine authorized backups and file-system remnants
  3. Treat embedded author metadata as a lead requiring corroboration
  4. Inspect verified file type and acquisition context safely

Explanation

Correct Answer

B:

Deleted data may persist in backups or unallocated space. Recovery depends on storage behavior and retention, not a guarantee.

Incorrect Answers

A:

Version differences can reveal changed values and timing; it can be useful for efforts to reconstruct file version history after a disputed edit. The actor behind each change may still need audit corroboration; the current question is about how to look for deleted spreadsheet remnants.

C:

Document properties can be inherited, edited, or copied from templates; that is the consideration when a team tries to interpret document authorship metadata cautiously. They are not conclusive proof of who drafted the file; that would leave unresolved the present need to look for deleted spreadsheet remnants.

D:

Display settings can mask extensions; that is why it can help to interpret hidden file extensions correctly. Content inspection in a controlled environment prevents unsafe execution and false classification; it would not by itself meet the stated need to look for deleted spreadsheet remnants.

Question 542

A Word file lists an employee name in its author property. How should the examiner proceed to interpret document authorship metadata cautiously?

  1. Disclose recovery limitations and inspect other data sources
  2. Examine authorized backups and file-system remnants
  3. Compare authenticated versions and edit timestamps
  4. Treat embedded author metadata as a lead requiring corroboration

Explanation

Correct Answer

D:

Document properties can be inherited, edited, or copied from templates. They are not conclusive proof of who drafted the file.

Incorrect Answers

A:

Overwrite behavior and SSD garbage collection may remove recoverable bytes; it belongs to a different stage of work: trying to avoid claiming successful recovery from overwritten space. Failure to recover is not proof a file never existed; this case asks for a means to interpret document authorship metadata cautiously instead.

B:

Deleted data may persist in backups or unallocated space; it protects the separate goal to look for deleted spreadsheet remnants. Recovery depends on storage behavior and retention, not a guarantee; the immediate evidentiary task here is to interpret document authorship metadata cautiously.

C:

Version differences can reveal changed values and timing; this addresses a different question: how to reconstruct file version history after a disputed edit. The actor behind each change may still need audit corroboration; the priority under these facts is to interpret document authorship metadata cautiously.

Recovery depends on storage behavior and retention, not a guarantee; it is not a substitute for a step that would avoid claiming successful recovery from overwritten space.

C:

Document properties can be inherited, edited, or copied from templates; this is a sensible safeguard where the issue is to interpret document authorship metadata cautiously. They are not conclusive proof of who drafted the file; it does not address the specific requirement to avoid claiming successful recovery from overwritten space.

E:

Version differences can reveal changed values and timing; it supports the separate objective to reconstruct file version history after a disputed edit. The actor behind each change may still need audit corroboration; it serves another purpose, not the immediate need to avoid claiming successful recovery from overwritten space.

Question 545

Question 546

An employee denies viewing a confidential cloud folder after termination notice. Which investigative method is best suited to establish whether a suspect account accessed cloud data?

  1. Correlate flow logs, process artifacts, and approved business transfers
  2. Reconstruct email, identity, and payment-approval events
  3. Check log licensing, event types, retention, and disabled auditing
  4. Review available provider access audit logs and authentication context

Explanation

Correct Answer

D:

Cloud logs may identify sessions and actions, subject to retention and configuration. They do not automatically identify a unique human operator.

Incorrect Answers

A:

Network volume is a screening indicator; that is the consideration when a team tries to trace a suspicious outbound network transfer. Application context is required to determine whether the transfer was legitimate; the examiner still needs to establish whether a suspect account accessed cloud data.

B:

A timeline may link account compromise to diverted payment; it belongs to a different stage of work: trying to assess a phishing-related diversion of funds. Mere temporal proximity does not establish causation; the examiner still needs to establish whether a suspect account accessed cloud data.

C:

Missing records can reflect collection limitations rather than no activity; it belongs to a different stage of work: trying to confirm what a SaaS audit log actually covers. Logging capabilities vary by platform and configuration; it does not address the specific requirement to establish whether a suspect account accessed cloud data.

Question 547
