The correct answer is to document who collected the evidence, when and where it was collected, cryptographic hash values, transfer details, and the storage location. This is because chain of custody documentation for forensic acquisition must establish a complete, unbroken record that proves evidence integrity and admissibility in legal proceedings; every transfer or handling action must be logged to prevent claims of tampering. On the CompTIA CySA+ CS0-003 exam, this concept tests your understanding of forensic procedures during post-compromise review, often appearing in scenario-based questions where a common trap is to focus only on the hash value while omitting the collector’s identity or transfer method. A useful memory tip is the acronym “WWHHT” — Who, When, Where, Hash, and Transfer — which covers the five critical elements that make your documentation defensible during post-incident improvement and before case closure.
CS0-003 Incident Response and Management Practice Question
This CS0-003 practice question tests your understanding of incident response and management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a post-compromise review, a laptop may contain evidence for a legal investigation. What should the responder document during acquisition? During post-incident improvement, which decision is most defensible? which action should be prioritized before closure?
Why wrong: Device description alone is inadequate.
B
Only the ticket priority
Why wrong: Ticket priority is not chain-of-custody documentation.
C
Only the user's job title
Why wrong: A job title does not preserve evidence integrity.
D
Who collected it, when, where, hash values, transfer details, and storage location
Chain of custody records evidence handling and integrity from collection onward. In post-incident improvement, responders need action that reduces risk while preserving the investigation record.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Who collected it, when, where, hash values, transfer details, and storage location
Option D is correct because forensic acquisition requires a complete chain of custody to ensure evidence integrity and admissibility in legal proceedings. Documenting who collected the evidence, when and where it was collected, cryptographic hash values (e.g., SHA-256) to verify data integrity, transfer details (e.g., write-blocker used, network path), and storage location provides a defensible record that meets legal and organizational standards.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that minimal documentation (like color or job title) is sufficient, when in fact comprehensive chain-of-custody details are required for legal defensibility.
Detailed technical explanation
How to think about this question
Forensic acquisition typically uses tools like FTK Imager or dd with a write-blocker to create a bit-for-bit copy, and hash values (MD5, SHA-1, or SHA-256) are computed before and after transfer to verify integrity. Chain-of-custody documentation must include timestamps with timezone offsets, hardware serial numbers, and the exact command syntax used, as even minor omissions can lead to evidence being challenged under Daubert or Frye standards.

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.

What is the correct answer to this question?
The correct answer is: Who collected it, when, where, hash values, transfer details, and storage location — Option D is correct because forensic acquisition requires a complete chain of custody to ensure evidence integrity and admissibility in legal proceedings. Documenting who collected the evidence, when and where it was collected, cryptographic hash values (e.g., SHA-256) to verify data integrity, transfer details (e.g., write-blocker used, network path), and storage location provides a defensible record that meets legal and organizational standards.

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. In a regulated payment environment, a laptop may contain evidence for a legal investigation. What should the responder document during acquisition? During post-incident improvement, which decision is most defensible? which action best reduces risk without losing evidence?
easy
A.Only the laptop colour
B.Only the ticket priority
C.Only the user's job title
✓ D.Who collected it, when, where, hash values, transfer details, and storage location
Why D: Option D is correct because legal and regulatory requirements demand a complete chain of custody for digital evidence. Documenting who collected the laptop, when, where, hash values (e.g., SHA-256), transfer details, and storage location ensures the evidence is admissible and tamper-proof. This aligns with NIST SP 800-86 and ISO 27037 forensic best practices.
Variation 2. While supporting a hybrid workforce, a laptop may contain evidence for a legal investigation. What should the responder document during acquisition? During post-incident improvement, which decision is most defensible? which evidence should guide the decision?
medium
A.Only the laptop colour
B.Only the ticket priority
C.Only the user's job title
✓ D.Who collected it, when, where, hash values, transfer details, and storage location
Why D: Option D is correct because forensic acquisition requires a complete chain of custody to ensure evidence admissibility in legal proceedings. Documenting who collected the evidence, when and where it was collected, hash values (e.g., SHA-256) for integrity verification, transfer details (e.g., using a write-blocker and forensic imaging tool like FTK Imager), and the storage location (e.g., secure evidence locker or encrypted NAS) satisfies legal and organizational standards such as NIST SP 800-86.
Variation 3. A laptop may contain evidence for a legal investigation. What should the responder document during acquisition? During post-incident improvement, which decision is most defensible?
hard
A.Only the laptop colour
B.Only the ticket priority
C.Only the user's job title
✓ D.Who collected it, when, where, hash values, transfer details, and storage location
Why D: Option D is correct because proper chain of custody documentation is critical for evidence admissibility in legal proceedings. The responder must record who collected the evidence, the exact date and time, the physical location, cryptographic hash values (e.g., SHA-256) to verify integrity, transfer details (e.g., chain-of-custody forms), and the secure storage location. This ensures the evidence is not tampered with and can be defended in court.
