Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Maintaining an unbroken chain of custody

Chain of custody documents every person who handled the evidence, from collection to presentation in court, ensuring that evidence has not been tampered with. This is essential for admissibility.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Storing evidence in a secure locker

    Why it's wrong here

    Secure storage is part of chain of custody but not the entire process.

  • ✓

    Maintaining an unbroken chain of custody

    Why this is correct

    Chain of custody is the foundational process for evidence integrity.

  • ✗

    Using write-blockers when imaging drives

    Why it's wrong here

    Write-blockers prevent modification but are part of the process; chain of custody ensures accountability.

  • ✗

    Hashing the evidence with SHA-256

    Why it's wrong here

    Hashing verifies integrity but does not prove handling history.
