CHFI Computer Forensics Fundamentals and Process Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  The evidence must have been obtained with a warrant.

  Why it's wrong here

  The warrant requirement arises under the Fourth Amendment and governs how law enforcement may lawfully seize evidence; it is a constitutional constraint on searches, not a scientific admissibility standard. Frye v. United States (1923) asks whether the scientific technique itself is generally accepted by the relevant scientific community, regardless of how the evidence was acquired. Evidence obtained without a warrant may still be admissible if an exception applies, and warrantless acquisition does not automatically taint the scientific method used.

• ✗

  The evidence must be relevant and more probative than prejudicial.

  Why it's wrong here

  This describes the Rule 403 balancing test, which permits exclusion of otherwise relevant evidence if its probative value is substantially outweighed by unfair prejudice, confusion, or waste of time. That test applies to all evidence at trial, not specifically to scientific expert testimony. Frye, in contrast, is a pre-admissibility gatekeeping standard focused on the consensus of the scientific community about the reliability of a particular technique, not on the weighing of probative value against prejudice.

• ✗

  The evidence must have been peer-reviewed and published.

  Why it's wrong here

  Peer review and publication are explicit factors in the Daubert standard (adopted by the Supreme Court in 1993), not requirements under Frye. Frye's sole inquiry is whether the technique has gained general acceptance in the relevant scientific field, which may occur without formal peer review or publication. While peer review can be evidence of acceptance, it is neither necessary nor sufficient under Frye; conversely, an unpublished technique can still be generally accepted among practitioners.

• ✓

  The evidence must be based on techniques generally accepted in the scientific community.

  Why this is correct

  Under the Frye standard, scientific evidence is admissible only when the methodology or technique on which it is based has achieved general acceptance within the relevant scientific community. This standard, established in Frye v. United States, does not require universal agreement but rather substantial consensus among experts in the applicable field. It is a threshold test for the admissibility of novel scientific evidence, separate from rules about relevance, prejudice, or constitutional procedure.
