- A
Shut the laptop down immediately to prevent further encryption activity.
Why wrong: Powering off may stop malware activity, but it can destroy volatile evidence such as memory contents and active network sessions.
- B
Isolate the laptop from the network while keeping it powered on for volatile evidence collection.
The best first action is to contain the threat without destroying live evidence. Disconnecting network access limits further spread or command-and-control activity, while keeping the system powered on preserves memory, running processes, and other volatile artifacts that may be critical to the investigation. This balances containment with evidence preservation, which is exactly what responders need at the start of an incident.
- C
Ask the user to close all open applications and log off normally.
Why wrong: Logging off can destroy session data, running-process context, and other volatile artifacts needed for later investigation.
- D
Start deleting suspicious files to reduce the impact of the ransomware.
Why wrong: Deleting files risks destroying evidence and does not reliably remove the threat or stop encryption activity already in progress.
SY0-701 Security Operations Practice Question
This SY0-701 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.
An employee reports a ransomware note on a finance laptop. The laptop is still powered on, connected to Wi-Fi, and the user says they were just working in a spreadsheet. Management wants the fastest safe response that also preserves evidence. What should the responder do first?

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
Isolate the laptop from the network while keeping it powered on for volatile evidence collection.
Option B is correct because the immediate priority is to contain the ransomware while preserving volatile evidence (e.g., memory contents, running processes, network connections) that could be critical for forensic analysis. Powering off the laptop (Option A) would destroy volatile data and may allow the ransomware to persist or trigger additional encryption on reboot. Isolating the network connection stops the ransomware from communicating with its command-and-control server or spreading laterally, while keeping the system powered on allows a responder to capture memory with tools like FTK Imager or LiME before performing a controlled shutdown.
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.
- ✗
Shut the laptop down immediately to prevent further encryption activity.
Why it's wrong here
Powering off may stop malware activity, but it can destroy volatile evidence such as memory contents and active network sessions.
- ✓
Isolate the laptop from the network while keeping it powered on for volatile evidence collection.
Why this is correct
The best first action is to contain the threat without destroying live evidence. Disconnecting network access limits further spread or command-and-control activity, while keeping the system powered on preserves memory, running processes, and other volatile artifacts that may be critical to the investigation. This balances containment with evidence preservation, which is exactly what responders need at the start of an incident.
Clue confirmation
The clue word "first" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that shutting down a compromised system is the safest immediate action, but the trap here is that volatile evidence is lost and the ransomware may have anti-forensic shutdown triggers, making network isolation the correct first step.
Detailed technical explanation
How to think about this question
Ransomware often operates in memory, holding encryption keys or decryption tools in RAM until the system is rebooted. Network isolation (e.g., disabling the Wi-Fi adapter or unplugging the Ethernet cable) stops C2 beaconing and lateral movement, but the system remains powered so that a memory dump can be performed using tools like WinPmem or Magnet RAM Capture. In real-world incidents, responders may also capture a full disk image before shutdown to preserve evidence of the encryption process and any remnants of the ransomware binary.
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 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.
