Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Preventive: Firewall rules that block unauthorized traffic
Why this is correct
Preventive controls are designed to prevent incidents from occurring; blocking unauthorized traffic is a prime example.
- ✓
Detective: Intrusion detection system alerts on suspicious activity
Why this is correct
Detective controls identify and report ongoing or past incidents; IDS alerts serve this purpose.
- ✓
Corrective: Restoring data from backup after a ransomware attack
Why this is correct
Corrective controls remediate the effects of an incident; data restoration is a typical corrective action.
- ✓
Deterrent: Security warning banners on login screens
Why this is correct
Deterrent controls discourage malicious behavior by raising the perceived risk; warning banners are a common deterrent.
- ✗
Preventive: Restoring data from backup after a ransomware attack
Why it's wrong here
Incorrect — this describes a corrective control, not preventive. Preventive controls act before an incident.
- ✗
Detective: Firewall blocks unauthorized traffic
Why it's wrong here
Incorrect — this describes a preventive control, not detective. Detective controls identify, not block.
