PAS-C01 Design of SAP Workloads on AWS Practice Question
Which THREE of the following are valid strategies for disaster recovery (DR) of SAP workloads on AWS? (Select THREE.)
⚠ Common exam trap
Candidates often confuse 'warm standby' with 'pilot light' because both involve a scaled-down environment, but the key distinction is that pilot light requires manual scaling of compute resources during DR, whereas warm standby typically runs a continuously running, reduced-capacity environment that can be promoted without manual scaling.

Correct answer & explanation
✓
Pilot light environment with replicated data volumes that can be attached to EC2 instances in DR.
A pilot light DR strategy for SAP on AWS involves replicating data volumes (e.g., using EBS snapshots or storage replication) to a secondary region and keeping a minimal set of core services running. In a disaster, EC2 instances are launched and the replicated volumes are attached, allowing the SAP application stack to be started quickly. This approach balances cost and recovery time by avoiding a fully scaled environment during normal operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Warm standby with a fully scaled-down environment that is manually scaled up during DR.
Why it's wrong here
Warm standby typically involves automatic scaling and replication.
- ✓
Pilot light environment with replicated data volumes that can be attached to EC2 instances in DR.
Why this is correct
Pilot light uses replicated data that can be quickly activated.
- ✓
Regular backup of SAP systems to Amazon S3 and restore in another region.
Why this is correct
Backup and restore is a valid DR method.
- ✓
SAP HANA System Replication across AWS Regions.
Why this is correct
HSR can replicate data to a DR region for failover.
- ✗
Multi-site active-active with real-time replication and automatic failover.
Why it's wrong here
This is an HA strategy, not DR.

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 |
