Part I: Foundations of Digital Forensics & Legal Compliance
Q1: An investigator receives a sealed envelope containing a USB flash drive from the
company's legal department. The envelope is labeled with a case number but has no
other documentation. What is the investigator's very first priority?
A. Plug the USB into a forensic workstation to check its contents.
B. Create a chain-of-custody entry documenting who transferred the drive, when, and the
condition of the seal. [CORRECT]
C. Photograph the USB drive and then place it in an evidence locker.
D. Email the legal department asking for a copy of the case number.
Correct Answer: B
Rationale: The best answer is B. Chain of custody starts the instant evidence changes
hands. You record who gave it to you, when, where, and what condition it was in. That
documentation is what keeps the evidence admissible if the case ever sees a
courtroom. Jumping into technical steps before paperwork is a classic way to
compromise an investigation.
,Q2: A judge is evaluating whether to admit testimony about a novel forensic technique
for recovering data from damaged SSDs. The defense argues the method has not been
independently tested. Under which standard is the judge most likely evaluating this
challenge?
A. The Frye standard
B. The Daubert standard [CORRECT]
C. The Federal Rules of Civil Procedure
D. The Brady Rule
Correct Answer: B
Rationale: The best answer is B. Daubert specifically evaluates whether expert
testimony and the underlying methods are reliable, testable, and have known error rates.
Independent testing is one of the key Daubert factors. If the technique hasn't been
vetted, a judge may rule it inadmissible.
Q3: A first responder enters a server room and finds a rack-mounted system that is
powered on, a tablet on a shelf, and a backup tape in a drive. According to standard
order of volatility, which evidence should be addressed first?
A. The backup tape because magnetic media degrades quickly.
B. The tablet because it has a limited battery.
C. Volatile data from the running server, including RAM and active processes.
[CORRECT]
D. The server's hard drives because they contain the most persistent data.
,Correct Answer: C
Rationale: The best answer is C. Volatile data—RAM, running processes, open network
sockets—disappears the moment you disturb the system. You capture that first, then
secure the mobile devices, then deal with non-volatile storage. If you start with the tape
or the tablet, the live system state evaporates forever.
Q4: An employee works in an open-plan office with no assigned desk. The employer
wants to search the employee's assigned company laptop for policy violations. Which
statement is most accurate?
A. The employer needs a search warrant because the open office creates privacy rights.
B. The employer may generally search company-owned equipment without a warrant
based on ownership and policy. [CORRECT]
C. The employer must obtain consent from every employee in the open-plan area.
D. The Fourth Amendment prohibits all workplace searches without judicial approval.
Correct Answer: B
Rationale: The best answer is B. When the employer owns the hardware and has a clear
policy stating equipment is subject to monitoring or search, they generally don't need a
warrant or consent. The employee's expectation of privacy on company equipment is
typically reduced. State laws and union agreements can add wrinkles, but the general
principle holds.
Q5: After imaging a suspect's drive, the examiner computes SHA-256 hashes of both
the original and the image. The hashes match perfectly. What has the examiner
definitively established?
A. The suspect is guilty of the alleged crime.
, B. The forensic image is a bit-for-bit duplicate of the original source. [CORRECT]
C. The original drive has been write-protected since the imaging.
D. No malware exists on the drive.
Correct Answer: B
Rationale: The best answer is B. Matching hashes prove integrity—they confirm the copy
is bit-for-bit identical to the source. It doesn't tell you anything about the content being
good or bad, and it certainly doesn't freeze the original drive in time. Hashing verifies the
copy, not the nature of the evidence.
Q6: A forensic expert wants to testify about the results of a proprietary steganography
detection tool. The defense objects on the grounds that the tool is not generally
accepted in the digital forensics community. Which standard is most relevant?
A. The Daubert standard
B. The Frye standard [CORRECT]
C. The Best Evidence Rule
D. The Hearsay Rule
Correct Answer: B
Rationale: The best answer is B. Frye asks whether the method is generally accepted in
the relevant scientific community. If steganography detection techniques are widely
used and recognized by other forensic professionals, they pass Frye. It's about
consensus in the field, not about the expert's personal credentials.
