FC0-U71 Practice Question: After a ransomware attack, which step should be…
After a ransomware attack, which step should be taken FIRST in the incident response process?
⚠ Common exam trap
CompTIA often tests the misconception that the first step should be to restore from backups or notify authorities, but the correct first step is always containment to stop the spread of the attack.

Correct answer & explanation
✓
Disconnect affected systems from network
The first step in incident response after a ransomware attack is to contain the threat by disconnecting affected systems from the network. This prevents the ransomware from encrypting additional files on other systems and stops lateral movement, which is critical because ransomware often uses network shares and SMB protocols to spread. Immediate isolation preserves forensic evidence and limits the scope of the incident before any other actions are taken.

Disconnecting stops the spread and limits damage, a crucial first step.
- ✗
Restore from backup
Why it's wrong here
Restoring from backup is part of recovery but should occur after containment and assessment.
