The answer is to capture the contents of volatile memory (RAM) first using a memory acquisition tool. This is correct because the order of volatility in forensic evidence collection dictates that data which is most easily lost—such as running processes, active network connections, and encryption keys residing in RAM—must be preserved before any non-volatile storage like hard drives. In the context of the ISC2 Certified in Cybersecurity CC exam, this question tests your understanding of incident response procedures and the forensic principle that volatile data is irrecoverable after a power loss. A common trap is to start imaging the hard drive or copying logs, but that would destroy the most transient evidence. Remember the mnemonic “RAM before ROM” to reinforce that memory capture always comes first in the acquisition sequence.
ISC2 CC Security Operations Practice Question
This CC practice question tests your understanding of security operations. 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 forensic analyst responding to a reported compromise of a Linux web server. The server hosts a public-facing web application and is part of a DMZ. The initial investigation shows that unauthorized outbound connections were made to a known malicious IP address during the previous night. The server is still running and connected to the network, but the web application has been taken offline for maintenance. The incident response team wants to preserve evidence for potential legal action. You have a forensic workstation with tools like dd, netcat, and memory acquisition tools. Which of the following should be your FIRST step in the forensic acquisition process?

Correct answer & explanation
✓
Capture the contents of volatile memory (RAM) using a memory acquisition tool.
Volatile memory (RAM) contains critical evidence such as running processes, network connections, encryption keys, and in-memory malware that would be lost when the system is powered off. In a forensic response, the order of volatility dictates that RAM must be captured first before any non-volatile data. Option D is correct because it follows the established forensic principle of preserving the most volatile data first.
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.
✗
Create a bit-for-bit copy of the hard drive using dd and a write blocker.
Why it's wrong here
Disk imaging is important but volatile data should be captured first.
✗
Capture network traffic from the server for analysis.
Why it's wrong here
Network traffic captures current connections but memory contains more contextual evidence.
✗
Run a full antivirus scan to identify malware.
Why it's wrong here
Running antivirus may alter evidence and is not a forensic preservation step.
✓
Capture the contents of volatile memory (RAM) using a memory acquisition tool.
Why this is correct
Memory is most volatile and contains critical evidence.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the 'order of volatility' principle, and the trap here is that candidates mistakenly prioritize disk imaging (Option A) because it is a familiar step, ignoring that RAM holds the most ephemeral and critical evidence.
Detailed technical explanation
How to think about this question
The order of volatility (RFC 3227) prioritizes capturing CPU registers, routing tables, and RAM before disk data. Memory acquisition tools like LiME or FTK Imager use kernel modules to dump RAM without altering the system state, preserving artifacts such as active network sockets (e.g., established connections to the malicious IP) and hidden processes. In a real-world scenario, failing to capture RAM first could lose evidence of a rootkit or memory-resident payload that disappears on reboot.

→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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
