CHFI Computer Forensics Investigation Process Practice Question
This CHFI practice question tests your understanding of computer forensics investigation 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.
During a forensic investigation, an analyst discovers that the suspect's hard drive was encrypted using BitLocker. The analyst has obtained the recovery key. Which of the following is the best next step to ensure data integrity?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a forensic image of the encrypted drive, then decrypt the image.
Option C is correct because creating a forensic image of the encrypted drive before decryption preserves the original evidence in its pristine, unaltered state. Decrypting the image later using the recovery key ensures that the original encrypted data remains intact and verifiable, maintaining data integrity throughout the investigation.
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.
✗
Decrypt the drive using the recovery key and then create a forensic image.
Why it's wrong here
Decrypting first modifies the drive, potentially altering evidence.
✗
Run a live analysis tool to extract encryption keys from memory.
Why it's wrong here
This does not address the need for a forensic image and may alter memory.
✓
Create a forensic image of the encrypted drive, then decrypt the image.
Why this is correct
This preserves the original encrypted state and allows analysis of the decrypted image.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Boot the suspect computer and copy files to an external drive.
Why it's wrong here
Booting modifies the system and does not preserve the full drive image.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the principle that forensic imaging must occur before any decryption or analysis to preserve evidence integrity, and candidates mistakenly believe decryption first is acceptable because they have the key.
Detailed technical explanation
How to think about this question
BitLocker uses full-disk encryption with AES (128 or 256-bit) and a separate recovery key stored as a 48-digit numerical password. Creating a forensic image of the encrypted drive (e.g., using dd or FTK Imager) captures the entire encrypted volume, including the BitLocker metadata and encrypted sectors. Decrypting the image offline with tools like Passware or Elcomsoft ensures the original drive remains untouched, and the image can be hashed (SHA-256) for integrity verification before and after decryption.
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 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.
