ISC2 CC Business Continuity, DR & Incident Response Practice Question
A small business with limited budget wants to ensure critical business functions can resume within 24 hours of a disaster. Their data changes infrequently. Which recovery solution is MOST cost-effective?
⚠ Common exam trap
ISC2 often tests the misconception that a warm site is the 'middle ground' for cost and recovery, but they ignore that cloud backup can achieve the same RTO at a fraction of the cost when data changes infrequently.

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
✓
Cloud backup with instant restore
Cloud backup with instant restore (Option B) is the most cost-effective solution because the business has a limited budget, data changes infrequently, and the RTO is 24 hours. Cloud backup eliminates the need for maintaining physical infrastructure, and instant restore from cloud snapshots can meet the 24-hour RTO without the high costs of a warm or hot site.
