- A
Pull the power cord from the laptop to immediately shut down the system and prevent any further system writes.
This is correct because powering off by unplugging immediately stops the operating system from writing any additional data to the hard drive, preserving the current state. After the system is off, the analyst can safely remove the drive and image it using a hardware write-blocker.
- B
Boot the laptop from a forensic boot CD that loads a write-blocker driver and then create a forensic image.
Why wrong: This is incorrect because booting from any media (even a forensic CD) will cause the BIOS and potentially the running forensic OS to write data to the suspect hard drive (e.g., creating temporary files or modifying the registry) before the write-blocker driver becomes active. The drive could be altered before the write-blocker is enforced.
- C
Perform a live acquisition of the hard drive using a network forensic tool while the system is still running.
Why wrong: This is incorrect because live acquisition involves interacting with the running system, which can modify file timestamps, memory, and temporary files. It also may not capture deleted or hidden data reliably. The goal is to preserve the hard drive's contents without any changes, so a live acquisition is not appropriate when a static image is required.
- D
Ask the suspect to log off and shut down the laptop normally, then remove the hard drive and image it using a write-blocker.
Why wrong: This is incorrect because a normal shutdown allows the operating system to perform writes, such as flushing disk caches, writing event logs, and updating registry hives. These writes can modify or destroy potential evidence. The analyst should never rely on a normal shutdown when the device is already on.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
A digital forensics analyst is investigating a suspected insider threat. The analyst has acquired a laptop used by the suspect. The analyst needs to obtain a forensic image of the hard drive without altering any data. The laptop is running and logged into the suspect's user account. Which of the following is the most appropriate first step for the analyst to take?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Pull the power cord from the laptop to immediately shut down the system and prevent any further system writes.
Option A is correct because immediately removing power (hard shutdown) stops all system writes and preserves the current state of the hard drive without any further changes. This is critical in forensic acquisition to maintain data integrity and avoid altering evidence, especially when the system is logged in and actively writing to the disk.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose live acquisition (Option C) thinking it preserves volatile data, but the question specifically asks for a forensic image of the hard drive without altering data, and a hard shutdown is the only method that guarantees no further writes to the disk.
Detailed technical explanation
How to think about this question
A hard shutdown (pulling the power cord) ensures that no further writes occur to the disk, which is essential for maintaining a forensic image that can be verified with a hash (e.g., SHA-256). In contrast, a live acquisition uses tools like dd or FTK Imager over a network, but the running OS continues to write to the disk (e.g., logs, temp files, and prefetch), making the image non-forensically sound. For SSDs, even a reboot can trigger TRIM commands that permanently erase deleted data, so a hard shutdown is preferred to preserve unallocated space.
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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
