PAS-C01 Technology Practice Question
An organization wants to ensure that its SAP HANA database backups are stored in a separate AWS Region for disaster recovery. The backups are currently stored in Amazon S3 in the primary Region. Which AWS service should be used to replicate the backups to another Region automatically?
⚠ Common exam trap
A common mix-up: candidates confuse AWS Backup's cross-region copy capability with S3 CRR, but AWS Backup is a managed backup service that does not automatically replicate existing S3 objects without a backup plan, whereas CRR is a native S3 feature designed specifically for continuous, automatic object replication across Regions.
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
✓
Amazon S3 Cross-Region Replication (CRR).
Amazon S3 Cross-Region Replication (CRR) is the correct choice because it automatically replicates objects from an S3 bucket in one AWS Region to a bucket in another Region, meeting the requirement for storing SAP HANA database backups in a separate Region for disaster recovery. CRR operates asynchronously at the object level, ensuring that backups are continuously copied without manual intervention, and it supports the same storage classes and encryption mechanisms as the source bucket.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon S3 Cross-Region Replication (CRR).
Why this is correct
S3 CRR automatically replicates objects to another Region.
- ✗
AWS Storage Gateway with volume gateway.
Why it's wrong here
Storage Gateway is for hybrid storage, not S3-to-S3 replication.
- ✗
AWS Backup with a cross-region backup plan.
Why it's wrong here
AWS Backup can copy snapshots, but for S3 objects, S3 CRR is more direct and automatic.
- ✗
Amazon S3 Transfer Acceleration.
Why it's wrong here
Transfer Acceleration improves upload speed, not replication.

| 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 |
