Quick Answer
The answer is LiME, the Linux Memory Extractor, which is the correct choice because it is a loadable kernel module specifically designed for full system memory acquisition on a running Linux system. Unlike user-space tools that cannot access kernel memory directly, LiME loads into the kernel to capture RAM with minimal footprint, ensuring a forensically sound image. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your understanding of Linux-specific acquisition tools versus general-purpose utilities like dd or memdump, which lack the kernel-level access required for complete RAM capture. A common trap is confusing LiME with FTK Imager or DumpIt, but those are Windows-focused; LiME is the standard for Linux memory forensics. Remember the mnemonic: LiME is the key to Linux Memory Extraction.
This CHFI practice question tests your understanding of storage forensics and file system analysis. 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, you need to acquire the RAM of a running Linux system. Which tool is specifically designed for memory acquisition on Linux?
Memdump
Why wrong: Memdump is a generic term, but there is no standard Linux tool called Memdump.
Volatility
Why wrong: Volatility is an analysis framework, not an acquisition tool.
WinPmem
Why wrong: WinPmem is for Windows memory acquisition, not Linux.
LiME
LiME is the recommended tool for Linux memory acquisition.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
LiME
LiME (Linux Memory Extractor) is a loadable kernel module that allows full system memory acquisition from Linux systems. It is the standard tool for Linux memory forensics.
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.
Memdump
Why it's wrong here
Memdump is a generic term, but there is no standard Linux tool called Memdump.
Volatility
Why it's wrong here
Volatility is an analysis framework, not an acquisition tool.
WinPmem
Why it's wrong here
WinPmem is for Windows memory acquisition, not Linux.
LiME
Why this is correct
LiME is the recommended tool for Linux memory acquisition.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
