PAS-C01 Migration Practice Question
A company is migrating a large-scale SAP environment to AWS. Which THREE AWS services can be used to optimize storage costs for SAP workloads? (Choose three.)
⚠ Common exam trap
Many candidates confuse AWS Storage Gateway (a hybrid caching service) with a cost optimization tool for native AWS SAP workloads, or assume that S3 Standard is sufficient for all data without considering lifecycle transitions to lower-cost tiers like Glacier.
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 Lifecycle policies to transition data
Amazon S3 Lifecycle policies (Option B) allow you to automatically transition SAP backup and archival data from S3 Standard to lower-cost storage classes like S3 Standard-IA or S3 Glacier, reducing storage costs without manual intervention. This is critical for SAP workloads where large volumes of backup data accumulate over time and do not require immediate access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Storage Gateway for on-premises caching
Why it's wrong here
Storage Gateway is for hybrid, not directly for SAP cost optimization.
- ✓
Amazon S3 Lifecycle policies to transition data
Why this is correct
Lifecycle policies move data to cheaper tiers.
- ✗
Amazon S3 Standard for all data
Why it's wrong here
Standard is costly for infrequently accessed data.
- ✓
Amazon S3 Glacier for long-term backup
Why this is correct
Glacier is low-cost archive storage.
- ✓
Amazon EBS Snapshots for incremental backups
Why this is correct
Snapshots are incremental and cost-effective.

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 |
