Q3. Which principle requires an investigator to avoid unnecessary changes to evidence?
A. Evidence integrity
B. Data compression
C. Screen resolution
D. Network routing
Correct Answer: A. Evidence integrity
Explanation: Evidence integrity requires data to remain complete and unaltered during handling and analysis. Compression and network routing serve unrelated purposes.
Q4. Which phase determines which devices and accounts may contain relevant evidence?
A. Identification
B. Reporting
C. Disposal
D. Formatting
Correct Answer: A. Identification
Explanation: Identification locates potential evidence sources before acquisition begins. Reporting presents findings after examination and analysis.
Chain of Custody, Hashing, and Preservation
Q5. What does chain of custody document?
A. The collection, transfer, storage, and handling of evidence
B. The speed of a processor
C. The size of a monitor
D. The design of a database table

A. The sequence in which rapidly changing evidence should be collected
B. The alphabetical order of file names
C. The colours used in a report
D. The order of user passwords
Correct Answer: A. The sequence in which rapidly changing evidence should be collected
Explanation: More volatile evidence is generally collected before persistent evidence. This reduces the risk of losing important data.
Q11. Live acquisition is performed when the system is:
A. Powered on and operating
B. Physically destroyed
C. Disconnected and permanently erased
D. Replaced by a printed document
Correct Answer: A. Powered on and operating

Q13. Dead acquisition normally examines:
A. A powered-off storage device
B. Only active network sessions
C. A running process in memory
D. A live video call
Correct Answer: A. A powered-off storage device
Explanation: Dead acquisition is generally performed on non-running media in a controlled environment. It cannot recover information that existed only in volatile memory.
Forensic Imaging and File Systems
Q14. A forensic image is best described as:
A. A controlled bit-level copy of evidence media
B. A screenshot of the desktop only
C. A list of visible file names
D. A normal document backup
Correct Answer: A. A controlled bit-level copy of evidence media
Explanation: A forensic image may preserve active files, deleted remnants, unallocated space, and file-system structures. A screenshot or ordinary file copy is less complete.
Q15. What may be found in unallocated space?
A. Remnants of deleted files
B. Only active user accounts
C. The physical keyboard layout
D. The monitor’s colour profile only
Correct Answer: A. Remnants of deleted files
Explanation: Unallocated space is not currently assigned to active files and may contain residual data. It may also contain unused or overwritten areas.
Q16. Slack space is:
A. Unused space within an allocated storage unit
B. The complete free space on a network
C. A type of password database
D. A mobile messaging application only
Correct Answer: A. Unused space within an allocated storage unit
Explanation: A file may not completely fill its final cluster, leaving unused bytes. These bytes may contain residual information.
Q17. File carving recovers data mainly by examining:
A. Content patterns and file signatures
B. User passwords only
C. Screen resolution
D. Folder colours
Correct Answer: A. Content patterns and file signatures
Explanation: File carving searches raw data for recognizable structures such as headers and footers. It may work even when directory records are missing.
Q18. Why may a deleted file still be recoverable?
A. Its storage area may not yet have been overwritten
B. Deletion always creates a second copy
C. The monitor stores every file permanently
D. The keyboard retains file contents
Correct Answer: A. Its storage area may not yet have been overwritten
Explanation: Many file systems mark deleted storage as available without immediately erasing its contents. Recovery becomes difficult after overwriting.
Memory and Network Forensics
Q19. Which artefact is commonly obtained from memory forensics?
A. Running processes
