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?
- Seek authorized original app data and context where feasible
- Assess precision, timestamp, source, and device attribution
- Use trained procedures to assess isolation, power, and volatile state
- Determine legal authority and practical acquisition options first
- Compare authenticated versions and edit timestamps
- 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?
- Compare authenticated versions and edit timestamps
- Examine authorized backups and file-system remnants
- Treat embedded author metadata as a lead requiring corroboration
- 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?
- Disclose recovery limitations and inspect other data sources
- Examine authorized backups and file-system remnants
- Compare authenticated versions and edit timestamps
- 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.

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?
- Correlate flow logs, process artifacts, and approved business transfers
- Reconstruct email, identity, and payment-approval events
- Check log licensing, event types, retention, and disabled auditing
- 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
