CCSP Practice Question: Which THREE of the following are key…
Which THREE of the following are key considerations when designing a disaster recovery plan for a cloud-based application?
⚠ Common exam trap
ISC2 often tests the misconception that disaster recovery planning can skip security controls or infrequent testing, but the exam emphasizes that DR must maintain security posture and be validated through regular, automated testing to meet compliance and operational requirements.
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
✓
Implementing cross-region replication for critical data.
Cross-region replication ensures that critical data is asynchronously or synchronously copied to a geographically separate cloud region, providing resilience against regional outages. This design directly supports disaster recovery by enabling failover to a secondary site with minimal data loss, often leveraging cloud-native services like AWS S3 Cross-Region Replication or Azure Geo-Redundant Storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Performing manual failover testing only once a year.
Why it's wrong here
Testing should be automated and frequent.
- ✗
Eliminating all security controls to speed up recovery.
Why it's wrong here
Security must not be compromised.
- ✓
Implementing cross-region replication for critical data.
Why this is correct
Cross-region replication ensures availability.
- ✓
Defining the Recovery Time Objective (RTO) for critical services.
Why this is correct
RTO is a key DR metric.
- ✓
Ensuring data consistency and integrity across replicated environments.
Why this is correct
Data consistency is vital.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
