1. A computer forensics examiner is imaging a seized hard drive for
analysis. Which technique ensures the image is a forensically sound
bit-for-bit copy without altering the original evidence?
A. Using the operating system’s copy command to duplicate files
B. Creating a logical extraction of important documents
C. Utilizing a write-blocker and forensic imaging software to create a
bitstream image
D. Copying only active files to save space
Rationale: Utilizing a hardware or software write-blocker and
specialized forensic imaging software produces a full bit-for-bit
image while protecting the integrity of the original drive, which is
foundational in digital forensics.
2. During a forensic acquisition, MD5 and SHA-256 hashes are calculated
for both the original drive and the image. What is the primary purpose
of generating these hashes?
A. To speed up the imaging process
B. To identify the file types on the drive
C. To verify that the forensic image is an exact, unaltered duplicate of
the original
D. To compress the data for storage
Rationale: Cryptographic hashes such as MD5 and SHA-256 create
unique fingerprints of data that allow the examiner to confirm that
, the acquired image matches the original bit for bit, which is critical
for evidentiary integrity.
3. A suspect’s laptop is seized in powered-off state. What is the most
appropriate immediate action to preserve volatile data?
A. Leave the system powered off and begin imaging
B. Remove the battery and hard drive before imaging
C. Boot into safe mode to disable encryption
D. Document the state, photograph settings, then perform live
capture of volatile memory if legally authorized
Rationale: Volatile data such as RAM contents are lost on power off;
a properly authorized live capture preserves this data, but should be
preceded by thorough documentation.
4. In a case involving encrypted drives, the examiner encounters full disk
encryption with pre-boot authentication. What should the examiner
attempt first?
A. Reformat the drive to access hidden partitions
B. Use brute force tools without suspect credentials
C. Obtain credentials or keys from lawful sources to decrypt the drive
D. Ignore encrypted drives and proceed with other evidence
Rationale: Full disk encryption protects data until proper credentials
or keys are provided; obtaining them through legal means preserves
evidence and avoids destructive cracking attempts.
5. While analyzing a Windows system, the examiner finds recently
accessed documents in the “Recent” registry keys. Which registry hive
contains this information?
A. SYSTEM
B. NTUSER.DAT
C. BOOT.DAT
D. SAM
Rationale: The NTUSER.DAT hive within each user profile stores
user-specific information, including MRU lists and recently accessed
documents.
6. What is the significance of the Master File Table (MFT) in NTFS file
systems for digital forensic analysis?
A. It stores only deleted files
, B. It contains metadata for every file and directory on the volume
C. It encrypts the file contents
D. It speeds up file access for users
Rationale: The MFT is a central structure in NTFS that stores
attributes and metadata of every file, which is invaluable for timeline
reconstruction and recovering deleted files.
7. An examiner uses keyword searching in a forensic tool and receives
numerous false positives. What is the best next step?
A. Exclude keyword search from analysis
B. Only search at the file system level
C. Re-image the drive
D. Refine the search terms and use proximity and context filters
Rationale: Refined search terms and contextual filters improve
precision, reducing false positives and focusing on relevant hits.
8. What forensic artifact on an iOS device can reveal the last network
connections made by the device?
A. Photos database
B. Wi–Fi association logs and connection history
C. SMS messages
D. Keyboard cache
Rationale: Network artifacts such as Wi–Fi associations and
connection history provide insight into recent networks the iOS
device joined, which can be vital for investigations.
9. What do file slack and unallocated space represent in forensic
investigation?
A. Active program execution memory
B. Temporary internet files only
C. Areas that can contain remnants of deleted or overwritten data
D. System registry backups
Rationale: File slack and unallocated space often hold fragments of
files that were deleted or partially overwritten, offering valuable
remnants during analysis.
10. In forensic analysis, which timeline analysis can best help
identify the sequence of events on a system?
A. Virus scan logs
, B. System BIOS settings
C. Correlation of file system timestamps, logs, and artifacts
D. User manual documentation
Rationale: Building a timeline by correlating timestamps from
various sources is key to understanding the sequence of actions on a
system.
11. What type of evidence is an email message stored on a forensic
image?
A. Testimonial evidence
B. Digital documentary evidence
C. Physical evidence
D. Demonstrative evidence
Rationale: Digital artifacts like email messages are documentary
evidence recorded in electronic form that can support facts about the
case.
12. An examiner finds a USB device connected to a workstation.
Where would the Windows registry store information about this
connection?
A. HKCU\Software\Microsoft
B. HKLM\SYSTEM\CurrentControlSet\Enum\USB
C. HKCR\CLSID
D. HKU.DEFAULT
Rationale: The registry key under
HKLM\SYSTEM\CurrentControlSet\Enum\USB stores details of USB
devices that have been connected, aiding in identifying removable
media usage.
13. Which of the following best describes hashing in digital
forensics?
A. Encrypting the hard drive
B. Backing up all files
C. Generating a fixed-length value representing data content
D. Deleting duplicate files
Rationale: Hashing produces a unique fixed-length value based on
data contents, enabling integrity verification and duplicate
detection.
