20+ practice questions focused on Computer Forensics Fundamentals and Process — one of the most tested topics on the Computer Hacking Forensic Investigator CHFI exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Computer Forensics Fundamentals and Process PracticeA forensic investigator is preparing to acquire the contents of a live system's RAM. Which of the following tools is specifically designed for this purpose and captures memory without altering the system state?
Explanation: FTK Imager is specifically designed for live memory acquisition on Windows systems, capturing RAM contents via a kernel-level driver (e.g., win32dd or FTK Imager's own memory capture module) that reads physical memory without modifying the system state. It creates a forensic image (e.g., .mem or .raw) while maintaining data integrity through hashing (MD5/SHA1). This makes it the correct choice for acquiring RAM from a live system without altering evidence.
Which of the following best describes the 'Best Evidence Rule' as it applies to digital evidence?
Explanation: The Best Evidence Rule requires that the original evidence be presented, but in digital forensics, a forensic image is considered the best evidence if the original is not practical.
Which THREE of the following are considered rules of evidence that digital evidence must satisfy to be admissible in court? (Select THREE)
Explanation: Authenticity (B) is a core rule of evidence: digital evidence must be shown to be what it purports to be, typically via hash values (e.g., MD5/SHA-256), chain of custody, and witness testimony, so it is correctly included. Completeness (D) is also a recognized evidentiary rule requiring that when part of a recording, file, or communication is introduced, the opposing party may require introduction of any other part needed in fairness, so it is correct. Admissibility (E) is the overarching requirement that evidence be relevant, material, and not excluded by rules such as hearsay or privilege before the court will accept it, making it correct. Best evidence (A) is a real doctrine but it is not one of the three rules listed here as the selected set, and Hearsay (C) is an exclusionary rule rather than a rule digital evidence must satisfy, so neither belongs among the marked correct answers.
During an investigation, an analyst creates a forensic image of a hard drive using FTK Imager and computes the MD5 hash of the image. Later, the hash is re-computed and found to match. What does this confirm?
Explanation: A matching MD5 hash confirms that the forensic image is bit-for-bit identical to the original drive at the time of acquisition and has not been modified since. MD5 is a cryptographic hash function that produces a 128-bit digest; any change to the image, even a single bit, would produce a completely different hash. This integrity verification is a foundational step in the forensic process to ensure the evidence is admissible and untampered.
A first responder arrives at a scene where a computer is powered on and the user is present. According to standard forensic first responder procedures, what should the responder do FIRST?
Explanation: The first priority at a live scene is to preserve volatile evidence and establish a chain of custody. Photographing the scene and documenting the system state (e.g., running processes, open network connections, logged-in users) captures critical volatile data before any action is taken. This aligns with the order of volatility (RFC 3227), which mandates capturing memory and system state before altering the system.
