- A
Test the write blocker on a non-evidence drive before connecting it to the suspect drive
Testing ensures the device is working properly.
- B
Use the write blocker to write data to the suspect drive to verify functionality
Why wrong: Writing to the suspect drive defeats the purpose of the write blocker.
- C
Use the same write blocker for both source and destination drives
Why wrong: The write blocker is only needed on the source drive to protect the original.
- D
Connect the write blocker between the suspect drive and the forensic workstation
The write blocker is placed in the path to prevent writes to the suspect drive.
- E
Bypass the write blocker if the imaging tool supports software write protection
Why wrong: Hardware write blockers provide a higher level of assurance.
CHFI Computer Forensics Fundamentals and Process Practice Question
This CHFI practice question tests your understanding of computer forensics fundamentals and process. 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.
Which TWO of the following are BEST practices when using a hardware write blocker during forensic acquisition? (Select TWO)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.

"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
Test the write blocker on a non-evidence drive before connecting it to the suspect drive
Option A is correct because testing the write blocker on a non-evidence drive verifies that the device is functioning correctly and will not inadvertently allow writes to the suspect drive. This step ensures the integrity of the forensic acquisition by confirming the write blocker's hardware-level protection is operational before it is connected to evidence.
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
The trap here is that candidates may confuse the role of a write blocker as a device that protects both source and destination drives, when in fact it is only used to protect the source (suspect) drive from accidental writes.
Detailed technical explanation
How to think about this question
Hardware write blockers operate at the ATA/SCSI command level, intercepting and blocking write commands (e.g., WRITE DMA, WRITE SECTOR(S)) while allowing read commands (e.g., READ DMA, IDENTIFY DEVICE) to pass through. In a real-world scenario, if a write blocker is not pre-tested, a faulty unit might pass write commands, leading to evidence contamination that could be challenged in court. The write blocker must be connected in series between the suspect drive and the forensic workstation, ensuring that all data flows through it for command filtering.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
