- A
Set up HANA System Replication (HSR) in asynchronous mode from the primary to a secondary EC2 instance in the DR Region. Use the same instance type and EBS configuration. In case of failure, perform a HSR takeover.
HANA System Replication (HSR) in asynchronous mode can achieve an RPO of seconds, well within the 15-minute requirement. The 1 Gbps Direct Connect connection, with HANA's built-in compression, can handle the 200 MB/s write throughput (approximately 1.6 Gbps uncompressed, compressed to ~800 Mbps or less). Using the same instance type and EBS RAID 0 configuration ensures performance parity after takeover. HSR takeover can be completed in minutes, meeting the 4-hour RTO. Option A is correct.
- B
Take EBS snapshots of the RAID array every 15 minutes and replicate them to the DR Region using EBS snapshot copy. In the DR Region, restore the snapshots to new volumes and attach them to a new EC2 instance.
Why wrong: EBS snapshots of a RAID array require stopping I/O for consistency, and taking snapshots every 15 minutes is impractical; restoring 4 TB from snapshots would significantly exceed the 4-hour RTO. Option B is incorrect.
- C
Back up the HANA database to Amazon S3 every 15 minutes using the HANA backup tool, and set up cross-Region replication for the S3 bucket. In the DR Region, restore the latest backup to a new EC2 instance.
Why wrong: Backing up to S3 every 15 minutes can impact database performance, and restoring from S3 takes longer than 4 hours due to data transfer and re-import time. Option C is incorrect.
- D
Use AWS Database Migration Service (DMS) to continuously replicate changes to a target HANA database in the DR Region.
Why wrong: AWS DMS does not natively support SAP HANA as a target for continuous replication; it is designed for heterogeneous migrations, not HANA-specific replication. Option D is incorrect.
SAP HANA Cross-Region Disaster Recovery
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs its SAP HANA database on an EC2 instance (r5.8xlarge) with 8 EBS gp2 volumes (1 TB each) in a RAID 0 stripe. The database is critical and requires high availability. The current architecture uses a single EC2 instance in one Availability Zone. The company wants to implement a disaster recovery solution with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 4 hours. The DR site must be in a different AWS Region. The SAP HANA database size is 4 TB. The company has a 1 Gbps Direct Connect connection between the primary and DR Regions. The database workload is write-intensive with an average write throughput of 200 MB/s. Which solution meets the RPO and RTO requirements?

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Same concept, more angles
3 more ways this is tested on PAS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is deploying SAP S/4HANA on AWS and needs to ensure that the system can be recovered within 4 hours in case of a disaster in the primary region. The secondary region is in a different AWS region. Which approach should be used to meet the recovery time objective (RTO)?
medium- ✓ A.Configure SAP HANA system replication to a secondary region with a pre-provisioned standby instance
- B.Use cross-region EBS snapshots and restore them in the secondary region
- C.Back up SAP HANA to Amazon S3 and restore in the secondary region
- D.Set up a pilot light environment using application-level replication
Why A: Replicating SAP HANA to a standby instance in another region using HANA system replication with pre-provisioned infrastructure allows fast failover. Cross-region EBS snapshots take time to restore. Backup and restore from S3 may be slower. Pilot light with application-level replication is not sufficient for HANA.
Variation 2. A company is designing a disaster recovery plan for SAP S/4HANA on AWS. The plan must have a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 2 hours. Which solutions can meet these requirements? (Choose TWO.)
medium- A.Multi-AZ deployment of SAP HANA within the same region
- B.SAP HANA log shipping to Amazon S3 every 15 minutes and restore in another region
- C.Cross-Region Amazon S3 backup and restore using AWS Backup
- ✓ D.Synchronous storage-level replication using EBS snapshots every 15 minutes and automated restore
- ✓ E.SAP HANA system replication to a secondary region with automatic failover
Why D: SAP HANA system replication with synchronous replication can achieve RPO of seconds and RTO of minutes. Storage-level replication with EBS snapshots scheduled every 15 minutes can achieve RPO of 15 minutes, but RTO may be longer due to restore time. However, with pre-warmed instances and automation, RTO of 2 hours is achievable. Log shipping to S3 may not meet RPO. Cross-Region Amazon S3 backup and restore is slower. Multi-AZ deployment in one region does not protect against region failure.
Variation 3. An SAP customer is running SAP HANA on AWS using m5.8xlarge instances. They want to implement a disaster recovery (DR) strategy using a secondary region with a standby HANA instance. Which TWO options should they consider to replicate the HANA data to the DR region? (Select TWO.)
medium- A.Use AWS Database Migration Service (DMS) to continuously replicate HANA to the DR region.
- ✓ B.Use Amazon EBS Snapshots and copy them to the DR region for periodic restore.
- ✓ C.Configure SAP HANA System Replication (HSR) to replicate data to the secondary region.
- D.Use Amazon EFS to replicate the HANA data directory to the DR region.
- E.Use AWS S3 Transfer Acceleration to continuously upload HANA log files to the DR region.
Why B: Options B and C are correct. SAP HANA System Replication is the standard method for replicating data between HANA instances across regions. Amazon EBS Snapshots can be copied to another region and used to restore volumes. Option A (AWS DMS) is for database migrations, not ongoing replication. Option D (Amazon EFS) is not suitable for HANA data volumes. Option E (S3 Transfer Acceleration) is not a replication method for HANA.
