The answer is to capture a full memory dump using a forensic tool like FTK Imager or WinPmem. This is correct because the order of volatility dictates that the most volatile data—system memory (RAM)—must be preserved first, as it contains running processes, active network connections, and encryption keys that vanish the instant the system is powered down or disconnected. In the Computer Hacking Forensic Investigator CHFI exam, this scenario tests your understanding of live incident response priorities, specifically the principle that memory capture first is non-negotiable when malware is actively exfiltrating data. A common trap is to immediately unplug the network cable or shut down the laptop, but that destroys the very evidence of the breach. Remember the mnemonic: “RAM before the RAM-ifications”—capture memory before any other action to avoid losing the volatile clues.
CHFI Incident Response and First Responder Skills Practice Question
This CHFI practice question tests your understanding of incident response and first responder skills. 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.
You are a first responder for a medium-sized company with 500 employees. The incident response team has been alerted to a possible data breach involving the CEO's laptop, which is a Windows 10 system. The CEO reports that the laptop has been acting strangely, with unusual pop-ups and slow performance. The laptop is currently powered on and connected to the corporate network via Wi-Fi. The CEO is logged in and has several applications open, including email and a web browser. The security team suspects malware may be exfiltrating sensitive documents. As the first responder, you must decide the best course of action to preserve evidence and contain the threat while minimizing impact on business operations. Which action should you take FIRST?

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 a full memory dump using a forensic tool like FTK Imager or WinPmem.
The correct first action is to capture a full memory dump using a forensic tool like FTK Imager or WinPmem. Since the laptop is powered on and malware is suspected, volatile data (including running processes, network connections, and encryption keys) is at risk of being lost. Preserving RAM is the highest priority in live incident response because it contains evidence of active malware and ongoing exfiltration that would be lost upon shutdown or disconnection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Capture a full memory dump using a forensic tool like FTK Imager or WinPmem.
Why this is correct
Memory capture preserves the most volatile evidence and should be the first step.

The clue words "best", "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disconnect the laptop from the corporate network immediately to stop any ongoing data exfiltration.
Why it's wrong here
Disconnecting first may lose volatile evidence such as active network connections and memory contents.
✗
Create a forensic image of the hard drive using a write blocker.
Why it's wrong here
Disk imaging is important but should be done after memory capture to preserve the most volatile data.
✗
Shut down the laptop to prevent further damage and preserve the disk.
Why it's wrong here
Shutting down destroys volatile evidence in memory.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the principle of 'order of volatility' (RFC 3227), where candidates mistakenly prioritize network disconnection or disk imaging over capturing volatile memory, which is the most fragile and time-sensitive evidence.
Detailed technical explanation
How to think about this question
Memory forensics relies on capturing the contents of RAM, which includes kernel objects, process lists, network sockets, and decrypted data. Tools like WinPmem use a kernel driver to read physical memory without altering the system state. In a real-world scenario, malware often runs entirely in memory (fileless malware) and would be lost if the system is powered off; capturing RAM first ensures that artifacts like injected code, encryption keys, and active network connections are preserved for analysis.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An analyst receives an alert indicating a suspicious process (PID 3342) is making outbound connections on port 443 to an unknown IP. The system is a Windows 10 workstation. Which first responder action is MOST appropriate?
easy
✓ A.Capture a full memory dump using a tool like FTK Imager (Memory Capture) or DumpIt.
B.Immediately disconnect the system from the network to contain the threat.
C.Check the Windows Event Logs for related entries.
D.Reboot the system to clear any malicious processes from memory.
Why A: Capturing a full memory dump (option A) is the most appropriate first responder action because it preserves the volatile state of the suspicious process (PID 3342) and its associated artifacts (e.g., network connections, loaded DLLs, encryption keys) before any further system changes occur. This allows forensic analysis to identify the malware's behavior, such as command-and-control (C2) communication over port 443 (HTTPS), without altering evidence. Tools like FTK Imager (Memory Capture) or DumpIt acquire a raw .mem file that can be analyzed with Volatility or Rekall to extract process details, network sockets, and injected code.
Variation 2. A security team suspects a data breach via an external attacker. The incident response plan requires preservation of evidence for legal proceedings. Which order of volatility should the first responder follow?
medium
A.Capture disk image, then memory, then network connections.
B.Record network connections, capture disk image, then memory.
✓ C.Capture memory, record network connections, acquire disk image, then collect backups.
D.Collect backups first, then disk image, then memory.
Why C: Option C is correct because the order of volatility (OOV) dictates that the most volatile data (memory/registers) must be captured first, followed by network connections, then disk images, and finally backups. This sequence minimizes data loss and ensures evidence integrity for legal proceedings, as volatile data is lost when power is removed.
Variation 3. During the initial response to a suspected data breach, a first responder discovers a live system with active network connections. The responder needs to preserve evidence while minimizing alteration. Which of the following is the MOST appropriate first step?
medium
✓ A.Use a memory acquisition tool to capture the contents of RAM.
B.Run a full disk imaging tool to capture the hard drive contents.
C.Disconnect the network cable to isolate the system from the network.
D.Immediately shut down the system by pulling the power cord.
Why A: A is correct because in a live system with active network connections, the most volatile evidence is in RAM (e.g., running processes, network connections, encryption keys). Using a memory acquisition tool (like FTK Imager or WinPmem) captures this volatile data before any other action, preserving evidence that would be lost on shutdown or disconnection. This aligns with the order of volatility (RFC 3227), which prioritizes memory over disk.
