Question 270 of 1,152
Security OperationsmediumMultiple ChoiceObjective-mapped

Quick Answer

The correct approach is to use a hardware write blocker and create a bit-by-bit forensic image with hashes. This is because a hardware write blocker physically intercepts and blocks any write commands at the bus level, ensuring the original media remains completely unaltered—a foundational requirement for forensic soundness. The bit-by-bit image captures every sector, including slack space and unallocated clusters, while generating cryptographic hashes (such as SHA-256 or MD5) before and after imaging provides a verifiable chain of custody and integrity check for court admissibility. On the Security+ SY0-701 exam, this concept tests your understanding of evidence preservation and the difference between logical and forensic imaging; a common trap is choosing a software write blocker, which relies on the operating system and can be bypassed. Remember the mnemonic “HWB + Hash = Court-Proof Evidence” to recall that hardware protection paired with cryptographic verification is the gold standard.

SY0-701 Security Operations Practice Question

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

Use a hardware write blocker and create a bit-by-bit forensic image with hashes.

Option B is correct because forensic best practice requires preserving the original media in an unaltered state. A hardware write blocker physically prevents any write commands from reaching the drive, ensuring the original evidence is not modified. Creating a bit-by-bit forensic image (e.g., with `dd` or FTK Imager) captures the entire drive, including slack space and unallocated sectors, and generating cryptographic hashes (SHA-256 or MD5) before and after imaging verifies the image's integrity for court admissibility.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • Mount the drive read-write so the investigator can browse it quickly.

    Why it's wrong here

    Read-write mounting risks modifying metadata, timestamps, or file system structures. That weakens the ability to prove the original drive was not altered.

  • Use a hardware write blocker and create a bit-by-bit forensic image with hashes.

    Why this is correct

    This is the best practice because a hardware write blocker prevents any accidental writes to the source drive, and a bit-by-bit image captures the exact data structure for analysis. Hashing the source or image before and after acquisition provides integrity verification, which is essential when evidence may be challenged later. Together, these steps protect the original media and support chain of custody and courtroom admissibility.

    Clue confirmation

    The clue word "best" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Copy only the user profile folders with a file manager to save time.

    Why it's wrong here

    A file copy omits slack space, deleted data, and other artifacts that may be crucial in a forensic investigation. It also provides weaker integrity assurance than a complete forensic image.

  • Boot the laptop normally and use backup software to duplicate the disk.

    Why it's wrong here

    Booting the system changes the evidence state, and backup software is not the same as forensic acquisition. The goal here is preservation, not convenience.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may think booting the laptop or using a file manager is acceptable for a quick preview, but any write access—even seemingly harmless metadata updates—renders the evidence inadmissible under Daubert or Frye standards.

Detailed technical explanation

How to think about this question

A hardware write blocker operates at the SATA or USB bridge level, intercepting ATA commands and blocking any non-read commands (e.g., WRITE DMA, SECURITY ERASE). This ensures that even if the forensic tool or OS attempts a write, the command never reaches the drive. The bit-by-bit image includes host-protected area (HPA) and device configuration overlay (DCO) regions, which standard file copies miss. In real-world cases, courts have rejected evidence when hash values did not match due to inadvertent writes, making the write blocker and hash verification non-negotiable.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. An investigator receives a suspect laptop that may be needed in court. The goal is to create a forensic image without changing the original drive contents. Which three actions best support chain of custody and evidence integrity? Select three.

hard
  • A.Use a hardware write blocker during acquisition so the original disk cannot be modified.
  • B.Record cryptographic hash values for both the original media and the forensic image.
  • C.Document every transfer of the laptop, including who had custody, when, and why.
  • D.Browse the original disk using the operating system file explorer to confirm the case folder is present.
  • E.Store the suspect drive and the forensic copy in the same unlocked folder to simplify access.

Why A: A hardware write blocker is essential because it physically prevents any write commands from reaching the suspect drive at the SATA/IDE or USB level, ensuring the original disk's contents remain unaltered during acquisition. This is a foundational requirement for maintaining evidence integrity in forensic imaging, as any modification could render the evidence inadmissible in court.
