The answer is contents of system memory (RAM), current network connections, and running processes. These three pieces of volatile data must be collected first because they represent the most ephemeral evidence on a system, governed by the order of volatility principle in first responder collection. RAM holds active processes, encryption keys, and malware that vanish instantly upon power loss, while network connections and running processes reveal live exfiltration channels and malicious activity that cease the moment the system is disconnected or shut down. On the Computer Hacking Forensic Investigator CHFI exam, this concept tests your understanding of the Locard’s Exchange Principle applied to digital forensics, often appearing as a scenario-based multiple-choice question where a common trap is to prioritize hard drive imaging over RAM capture. Remember the mnemonic “RCN” for RAM, Connections, Network processes—collect these before pulling the plug.
CHFI Incident Response and First Responder Skills Practice Question
This CHFI practice question tests your understanding of incident response and first responder skills. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 the initial response to a suspected data exfiltration, which THREE pieces of volatile data should be collected first? (Choose three.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
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
✓
Current network connections.
Current network connections (A) are volatile because they show active communication channels that could indicate data exfiltration in progress. If the system is shut down or disconnected, this evidence is lost immediately, making it a top priority for collection during initial response.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Current network connections.
Why this is correct
Network connections are transient and may disappear.

✓
List of running processes.
Why this is correct
Processes can start/stop quickly; must be captured early.

✓
Contents of system memory (RAM).
Why this is correct
Memory contains the most volatile data including encryption keys and active malware.

✗
Windows registry hives.
Why it's wrong here
Registry is stored on disk and is less volatile.
✗
Forensic image of the hard drive.
Why it's wrong here
Disk is non-volatile and can be collected later.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the Order of Volatility principle, and the trap here is that candidates mistakenly prioritize persistent data like registry hives or disk images over transient evidence that disappears immediately upon shutdown.
Detailed technical explanation
How to think about this question
Volatile data collection follows the Order of Volatility (RFC 3227), which prioritizes data that disappears when power is lost. Network connections (netstat -an), running processes (ps -ef or tasklist), and RAM contents (using tools like FTK Imager or LiME) are at the top because they vanish within milliseconds to seconds of shutdown. In a real-world scenario, an attacker might use encrypted tunnels (e.g., SSH or HTTPS) to exfiltrate data; capturing netstat output before the connection drops can reveal the remote IP and port.
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.

Variation 1. You are responding to a suspected malware infection on a Windows 10 system. The system is still running. Which of the following should you collect FIRST?
medium
✓ A.Acquire a memory dump using a tool like WinPmem.
B.Collect the Windows Event Logs.
C.Export the contents of the Windows Registry.
D.Create a forensic image of the hard drive.
Why A: When a system is still running and suspected of malware infection, the first priority is to capture volatile data, which includes the contents of RAM. WinPmem is a tool designed to acquire a memory dump from a live Windows system, preserving critical evidence such as running processes, network connections, and injected code that would be lost on shutdown. This follows the order of volatility (RFC 3227), which mandates collecting memory before any non-volatile data like logs, registry, or disk images.
