CCOA Securing Assets Practice Question
You are conducting an asset inventory and discover a device communicating with a known malicious IP address. The device is a corporate laptop. What is the most immediate, effective containment action?
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
✓
Use the 'Isolate Endpoint' feature in your EDR (e.g., CrowdStrike or Defender) to restrict network communication.
Isolating the endpoint via the EDR platform is the industry-standard 'containment' step to prevent lateral movement while maintaining a forensic connection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Power off the laptop immediately to preserve volatile memory.
Why it's wrong here
Powering off destroys volatile memory, which is critical for incident response forensics.
- ✗
Delete the user account associated with the laptop in Active Directory.
Why it's wrong here
Deleting the account will not prevent the malicious process from running on the local device.
- ✓
Use the 'Isolate Endpoint' feature in your EDR (e.g., CrowdStrike or Defender) to restrict network communication.
Why this is correct
Endpoint isolation via EDR allows for continued management of the device while blocking all network traffic except to the management console.
- ✗
Physically disconnect the ethernet cable from the building patch panel.
Why it's wrong here
This is impractical for remote users and doesn't stop Wi-Fi or cellular connections.
