Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Document the breach, its effects, and the remedial actions taken.
GDPR requires notification to the supervisory authority within 72 hours, communication to affected data subjects without undue delay, and documentation of the breach. Conducting a BIA is not a GDPR breach notification requirement, and restoring systems is part of recovery but not a specific GDPR requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Document the breach, its effects, and the remedial actions taken.
Why this is correct
Correct. GDPR requires documentation of all breaches.
- ✗
Restore all affected systems from the latest full backup.
Why it's wrong here
Incorrect. Restoring systems is an operational step, not a specific GDPR requirement.
- ✓
Communicate the breach to affected data subjects without undue delay if it poses a risk to their rights and freedoms.
Why this is correct
Correct. GDPR Article 34 requires communication to data subjects.
- ✗
Conduct a Business Impact Analysis (BIA) to determine the financial impact.
Why it's wrong here
Incorrect. BIA is not a GDPR requirement for breach notification.
- ✓
Notify the relevant supervisory authority within 72 hours of becoming aware of the breach.
Why this is correct
Under GDPR Article 33, a controller must notify the competent supervisory authority of a personal data breach without undue delay and, where feasible, within 72 hours of becoming aware of it. This requirement applies directly because the breach involves PII of EU residents, triggering the territorial scope of the GDPR. The 72-hour notification window is a mandatory procedural obligation distinct from the separate duty to communicate the breach to affected data subjects under Article 34.
