Pass your Western Governors University performance
assessment on the first attempt with this fully completed and
verified D829 Digital Forensics Incident Report. This high-yield
document provides a comprehensive unauthorized activity
analysis, featuring step-by-step forensic investigation
methodologies, evidence chain-of-custody documentation, and
critical remediation recommendations. It is an indispensable
resource for cybersecurity and digital forensics students looking to
understand report structures, align with grading rubrics, and
secure an A+ pass.
Question #1
During an incident response, which of the following is the FIRST step in the
digital forensics process?
A. Analysis of evidence
B. Reporting findings
C. Identification and preservation of the scene
D. Data acquisition
Correct Answer: C
Rationale: The forensic process begins with identification of potential
evidence and securing the scene to prevent alteration. Analysis (A),
acquisition (D), and reporting (B) come after the scene has been secured and
preserved.
,Question #2
A forensic investigator is called to a scene where a computer is powered on.
What is the MOST critical action to take first?
A. Pull the power plug immediately
B. Photograph the screen and system connections
C. Boot the system from a forensic USB drive
D. Begin running a virus scan
Correct Answer: B
Rationale: The first step at a live scene is to document everything
photographically (screen, cables, connections) before any physical interaction.
Pulling the plug (A) may lose volatile memory data. Booting from a USB (C)
alters the system state.
Question #3
Which of the following is the PRIMARY purpose of establishing a chain of
custody?
A. To ensure evidence is stored in a locked safe
B. To document every person who handled the evidence from collection to
court
C. To compress evidence files for storage efficiency
D. To generate a hash value of the evidence
Correct Answer: B
Rationale: Chain of custody documents the chronological history of the
evidence—who collected it, transferred it, and analyzed it. This ensures
admissibility by proving the evidence is authentic and unaltered. Hashing (D)
verifies integrity, not custody.
,Question #4
A forensic examiner creates a disk image using the dd command in Linux.
Which of the following is a critical parameter to ensure a bit-for-bit copy?
A. if=/dev/sda of=/dev/sdb bs=4096
B. cp /dev/sda /mnt/backup
C. dd if=/dev/sda of=/mnt/evidence.dd conv=noerror,sync
D. gzip /dev/sda > evidence.dd
Correct Answer: C
Rationale: The conv=noerror,sync option ensures that the dd command
continues reading despite read errors and pads blocks with zeros, creating a
complete bit-for-bit image. cp (B) and gzip (D) do not produce forensic-grade
images.
Question #5
A forensic image is hashed using SHA-1 and MD5. What is the purpose of
generating multiple hash values?
A. To speed up the imaging process
B. To increase the file size of the image
C. To provide redundant verification; if one algorithm is broken, the other
remains valid
D. To encrypt the image for security
Correct Answer: C
Rationale: Using both MD5 and SHA-1 provides a collision-resistant
redundancy. If one hash algorithm is compromised, the other still verifies
integrity. Speed (A) and file size (B) are not improved. Encryption (D) is a
separate process.
, Question #6
An investigator has seized a powered-off computer. What is the proper
order for evidence collection?
A. Hard drive → RAM → USB devices → printed materials
B. RAM → hard drive → USB devices → printed materials
C. Printed materials → USB devices → hard drive → RAM
D. Hard drive → printed materials → RAM → USB
Correct Answer: A
Rationale: If the system is off, volatile data (RAM) is already lost. The priority
is non-volatile storage: hard drive first, then external media (USB), then other
physical evidence. Printed materials are collected last in the order.
Question #7
Which of the following is an example of volatile data that should be
captured FIRST if a system is running?
A. Hard drive contents
B. Network configuration and current connections
C. Registry hives
D. Deleted files on the hard drive
Correct Answer: B
Rationale: Volatile data includes current network connections, running
processes, and RAM contents. These are lost upon power-off. Hard drive
contents (A), registry hives (C), and deleted files (D) are non-volatile and can
be recovered later.
Question #8
A first responder encounters a laptop that is locked with a password. The
screen is on and the user is logged in. The BEST action is:
