This CHFI practice question tests your understanding of computer forensics fundamentals and process. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 THREE of the following are essential steps in the digital forensics investigation process? (Select three.)
Examination
Examination involves searching for relevant data.
Analysis
Analysis interprets the data to reach conclusions.
Encryption
Why wrong: Encryption is a technique, not a process step.
Collection
Collection involves gathering digital evidence.
Destruction
Why wrong: Destruction is not a standard step in the process.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Examination
Option A (Examination) is correct because it is a core phase in the digital forensics process where investigators identify and extract potential evidence from collected data without altering it. This step involves techniques such as hashing (e.g., SHA-256) to verify integrity and using tools like FTK Imager or EnCase to preview files, ensuring the evidence is preserved in a forensically sound manner. Without examination, the raw collected data cannot be systematically reviewed for relevant artifacts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
EC-Council often tests the distinction between the forensic process steps and unrelated technical concepts like encryption or destruction, so candidates may mistakenly select 'Encryption' because they confuse a common obstacle with a required phase, or 'Destruction' because they think evidence must be destroyed after analysis.
Detailed technical explanation
The digital forensics process is often modeled after the NIST SP 800-86 framework, which includes Collection, Examination, Analysis, and Reporting. During examination, tools like Autopsy or X-Ways Forensics parse file systems (e.g., NTFS, ext4) to recover deleted files and metadata, while maintaining a chain of custody via cryptographic hashes. A real-world scenario is examining a suspect's hard drive for hidden partitions or slack space, where the examiner must avoid modifying timestamps or file attributes.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
