SECTION 1: FUNDAMENTALS OF DIGITAL FORENSICS (Questions 1-30)
Question 1
Which principle establishes that digital evidence must be preserved in its original form to
maintain admissibility in court?
A. Locard's Exchange Principle
B. Best Evidence Rule
C. Chain of Custody Doctrine
D. Forensic Soundness Principle
Correct Answer: B
Explanation: The Best Evidence Rule requires original evidence or verified copies to be
presented, ensuring digital evidence integrity is maintained for legal proceedings. This
principle prevents tampering claims.
Question 2
A forensic investigator arrives at a crime scene where a laptop is running with encrypted files
open. What should be the investigator's FIRST priority?
,A. Immediately shut down the computer to preserve the hard drive
B. Photograph the screen and capture volatile memory
C. Disconnect the network cable and unplug the power
D. Create a forensic image of the hard drive immediately
Correct Answer: B
Explanation: Capturing volatile data and photographing the screen preserves evidence that
would be lost upon shutdown, including encryption keys in RAM. Order of volatility dictates
this priority.
Question 3
Which of the following BEST describes the concept of "order of volatility" in digital forensics?
A. The sequence in which evidence should be presented in court
B. The priority ranking of data collection based on how quickly it disappears
C. The hierarchical structure of file systems during analysis
D. The chronological order of events in a cybercrime incident
Correct Answer: B
Explanation: Order of volatility prioritizes collecting the most perishable data first, such as
CPU registers and RAM, before less volatile storage like hard drives. This preserves critical
evidence.
Question 4
,During a forensic investigation, an examiner discovers that the system clock was
manipulated. What is the PRIMARY concern this creates?
A. The hard drive may have been physically damaged
B. File timestamps become unreliable for timeline reconstruction
C. The operating system will fail to boot properly
D. Network logs will be automatically deleted
Correct Answer: B
Explanation: Manipulated system clocks corrupt timestamps across file systems, making
timeline analysis unreliable and potentially invalidating chronological evidence
reconstruction. Investigators must verify time sources.
Question 5
Which forensic principle states that "every contact leaves a trace"?
A. Daubert Standard
B. Frye Standard
C. Locard's Exchange Principle
D. Principle of Forensic Triangulation
Correct Answer: C
Explanation: Locard's Exchange Principle, fundamental to forensics, posits that perpetrators
leave evidence and take evidence from crime scenes, applicable to digital traces. It guides
evidence search strategies.
, Question 6
A company experiences a data breach. The forensic team must determine if data was
exfiltrated. Which evidence source would BEST reveal data transfer activities?
A. Hard drive slack space
B. Firewall and proxy logs
C. CPU cache memory
D. Printer spool files
Correct Answer: B
Explanation: Firewall and proxy logs record network connections and data transfers,
providing evidence of exfiltration attempts and successful transfers. These logs are crucial
for network forensics.
Question 7
What is the PRIMARY purpose of creating a forensic image rather than examining the
original drive?
A. To compress data for easier storage
B. To preserve original evidence while enabling analysis
C. To encrypt sensitive information
D. To improve processing speed during examination
Correct Answer: B
