- A
Configure HANA System Replication to a secondary Region.
HANA System Replication provides near real-time replication.
- B
Use S3 cross-Region replication (CRR) to copy HANA backups.
Why wrong: S3 CRR is for S3 objects, not for HANA database replication.
- C
Copy EBS snapshots to another Region using cross-Region snapshot copy.
Cross-Region EBS snapshot copies can be used for DR.
- D
Use AWS Backup with cross-Region copy.
Why wrong: This is a backup method, not a DR approach by itself.

Use Amazon RDS cross-Region read replicas for HANA.
Why wrong: Amazon RDS does not support SAP HANA.
Question 1,146 of 1,733
Which Disaster Recovery Approaches are Valid for SAP HANA on AWS?
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is designing a disaster recovery (DR) strategy for SAP HANA on AWS. Which TWO of the following are valid DR approaches? (Choose two.)
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
✓
Configure HANA System Replication to a secondary Region.
Option A is correct because HANA System Replication (HSR) is a native SAP feature that asynchronously replicates the in-memory database to a secondary Region, enabling a full DR failover with minimal data loss. This approach is fully supported on AWS by deploying HANA instances in different Availability Zones or Regions, and it meets the RPO/RTO requirements for enterprise SAP HANA workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse backup replication (S3 CRR, AWS Backup) with live database replication (HSR), assuming any cross-Region copy mechanism qualifies as DR for HANA, when only HSR provides the required near-real-time data consistency and failover capability.
Detailed technical explanation
How to think about this question
HANA System Replication uses log shipping to keep a secondary system synchronized, with the option for synchronous or asynchronous replication; on AWS, you must configure the secondary instance in a different Region using a separate VPC and inter-Region VPC peering or AWS Transit Gateway. The replication relies on the HANA internal network protocol (TCP port 3xx41) and requires careful tuning of network latency (typically <10 ms RTT for synchronous mode) to avoid performance impact on the primary.
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.
TExam Day Tips
- 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
4 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 running SAP on AWS and needs to design a disaster recovery (DR) solution with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 4 hours. The primary region is us-east-1 and the DR region is us-west-2. The SAP application uses an SAP HANA database with a size of 2 TB. Which combination of AWS services should be used to meet the DR requirements most cost-effectively?
medium- A.Use AWS Database Migration Service (DMS) with continuous replication from the primary HANA database to a target in us-west-2.
- B.Use AWS Backup with continuous backups and cross-region copy to achieve RPO of 15 minutes.
- C.Use AWS Backup to take hourly backups of the HANA database and restore in us-west-2 during a disaster.
- ✓ D.Configure HANA System Replication (HSR) across regions and use a standby HANA instance in us-west-2 with a smaller instance size.
Why D: Option D is correct because HANA System Replication (HSR) is the native SAP HANA replication technology that can achieve an RPO of 15 minutes or less by asynchronously replicating data across regions. By using a smaller standby instance in us-west-2, the solution meets the RTO of 4 hours (since the standby can be scaled up or promoted quickly) while minimizing ongoing DR costs. This approach is purpose-built for SAP HANA and avoids the overhead of third-party tools or backup-based restores.
Variation 2. A company is designing a disaster recovery (DR) strategy for its SAP environment on AWS. The primary site is in us-east-1, and the DR site must be in us-west-2. The Recovery Point Objective (RPO) is 15 minutes, and the Recovery Time Objective (RTO) is 4 hours. Which TWO AWS services should be used to meet these objectives?
medium- A.Amazon Route 53 health checks to fail over DNS to the DR site.
- B.Amazon EC2 Auto Scaling groups to launch instances in us-west-2 on failover.
- ✓ C.SAP HANA System Replication configured with asynchronous replication to a HANA instance in us-west-2.
- ✓ D.AWS Elastic Disaster Recovery (AWS DRS) to continuously replicate SAP servers to us-west-2.
- E.AWS Backup to copy EBS snapshots to us-west-2 every 15 minutes.
Why C: SAP HANA System Replication with asynchronous mode can achieve an RPO of 15 minutes or less by continuously replicating log buffers from the primary HANA database in us-east-1 to a secondary HANA instance in us-west-2. This is the native SAP replication mechanism and directly meets the database-level RPO requirement. AWS Elastic Disaster Recovery (AWS DRS) continuously replicates entire SAP servers (including OS, applications, and data) to us-west-2, enabling full server failover within the RTO. Together, HANA replication handles database consistency while DRS covers the application and infrastructure layer, meeting both the RPO and RTO objectives.
Variation 3. A company is designing a disaster recovery (DR) strategy for its SAP environment on AWS. The primary site is in us-east-1 and the DR site in us-west-2. The SAP HANA database is 3 TB and uses HANA System Replication (HSR) in async mode. The RPO requirement is 15 minutes. What is the most cost-effective way to meet the RPO?
easy- A.Take full database backups to Amazon S3 every 15 minutes.
- B.Use EBS snapshots every 5 minutes to replicate data to DR region.
- C.Use HANA System Replication in synchronous mode to ensure zero data loss.
- ✓ D.Configure HANA System Replication in asynchronous mode over AWS Direct Connect.
Why D: Option D is correct because HANA System Replication (HSR) in asynchronous mode over AWS Direct Connect provides a low-latency, reliable network path that can achieve an RPO of 15 minutes without the performance penalty of synchronous replication. Asynchronous replication sends committed transactions to the DR site without waiting for acknowledgment, which is suitable for the 3 TB HANA database and meets the RPO requirement cost-effectively by avoiding the need for expensive, high-bandwidth dedicated connections or frequent full backups.
Variation 4. A company is designing a disaster recovery solution for SAP HANA on AWS using HANA System Replication. The primary site is in us-east-1 and the DR site is in us-west-2. Which TWO components are required to enable replication across Regions? (Choose two.)
hard- ✓ A.AWS Site-to-Site VPN or AWS Direct Connect between the two Regions
- B.VPC peering between the two VPCs
- C.Automated EBS snapshots of /hana/data and /hana/log volumes in us-east-1, copied to us-west-2
- D.AWS Global Accelerator
- E.Amazon S3 Transfer Acceleration
Why A: To enable HANA System Replication (HSR) across AWS Regions, the only required component from the options is reliable, low-latency network connectivity between the two regions. AWS Site-to-Site VPN or AWS Direct Connect provides a dedicated, secure network path that meets SAP's latency and stability requirements, avoiding the public internet. Option C (automated EBS snapshots) is not required because HSR performs an initial data synchronization automatically when the secondary HANA instance is started; manual snapshot replication is unnecessary and would only add complexity. VPC peering (B) is limited to same-region or does not guarantee the required performance, and Global Accelerator (D) and S3 Transfer Acceleration (E) are not designed for block-level replication of HANA data.
