PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP administrator is setting up a new SAP HANA system on AWS and needs to ensure that the system can recover from an Availability Zone failure. Which strategy should they implement for high availability?
⚠ Common exam trap
Candidates often confuse backup strategies (like EBS snapshots) with high availability, or mistakenly think that RDS Multi-AZ can be applied to SAP HANA, when in fact SAP HANA requires its own native replication mechanism (HSR) for cross-AZ failover.

Correct answer & explanation
✓
Set up HANA System Replication across two Availability Zones
HANA System Replication (HSR) is the native SAP mechanism for achieving high availability across Availability Zones (AZs). By replicating data synchronously or synchronously in-memory to a standby instance in a different AZ, it ensures automatic failover with minimal data loss in the event of an AZ failure. This directly meets the requirement for recovery from an AZ failure without relying on storage-level or database-agnostic approaches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Attach multiple Elastic Network Interfaces (ENIs) to the HANA instance
Why it's wrong here
Multiple ENIs do not provide HA for the database.
- ✗
Configure the HANA database with Amazon RDS Multi-AZ
Why it's wrong here
RDS Multi-AZ is for RDS databases, not HANA on EC2.
- ✓
Set up HANA System Replication across two Availability Zones
Why this is correct
HANA System Replication synchronously replicates data to a secondary system in another AZ for HA.
- ✗
Take EBS snapshots every hour and restore in another AZ
Why it's wrong here
Snapshots are for backup, not HA; recovery time would be too long.

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 |
