The correct answer is to capture volatile data first, then shut down normally, remove the drive, and image with a write blocker. This sequence follows the order of volatility in forensic acquisition, which prioritizes collecting the most ephemeral data—like RAM, active network connections, and running processes—because it vanishes the instant the laptop loses power. A graceful shutdown preserves file system integrity, while the write blocker ensures the drive is imaged without any alteration. On the CHFI exam, this principle tests your understanding of evidence preservation hierarchy; a common trap is to immediately pull the plug or remove the drive while the system is still running, which destroys volatile data and risks file corruption. Remember the mnemonic “V-S-D-I”: Volatile data, Shutdown, Drive removal, Image with blocker.
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.
A forensic examiner needs to acquire an image of a suspect's laptop hard drive. The laptop is running, and the examiner wants to capture volatile data first. According to best practices, which order of steps should the examiner follow?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "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.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Capture volatile data, then shut down normally, remove the drive, and image with a write blocker.
Option D is correct because forensic best practices mandate capturing volatile data (e.g., RAM, network connections, running processes) first, as this data is lost on power loss. After capturing volatile data, the examiner should perform a graceful shutdown to preserve file system integrity, then remove the drive and acquire a forensic image using a write blocker to prevent any modification to the original evidence.
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.
✗
Unplug the laptop, remove the drive, and boot the drive in a forensic workstation.
Why it's wrong here
Unplugging loses volatile data.
✗
Immediately remove the hard drive, then capture RAM from the drive.
Why it's wrong here
RAM is lost when power is removed; capture RAM first.
✗
Create a full disk image over the network while the laptop is running.
Why it's wrong here
Network imaging may alter the system and is not standard for first response.
✓
Capture volatile data, then shut down normally, remove the drive, and image with a write blocker.
Why this is correct
Volatile data first, then safe shutdown, then imaging.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think immediate power-off (Option A) preserves the disk state, but they forget that volatile data is lost and an unclean shutdown can corrupt the filesystem, making the image less reliable.
Detailed technical explanation
How to think about this question
Volatile data capture typically involves tools like FTK Imager, WinPmem, or LiME to dump RAM, followed by recording network connections (netstat), running processes (pslist), and open handles. The order of volatility (RFC 3227) dictates that CPU registers, routing tables, and ARP cache are captured before disk data. A graceful shutdown (not hard power-off) allows the OS to flush buffers and close files, reducing the risk of filesystem corruption that could hinder analysis.

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 practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
