- A
Use HANA System Replication to replicate the database to an EC2 instance running HANA in the target AWS environment, then perform a takeover.
HSR provides continuous replication with minimal downtime during the final switchover.
- B
Export the HANA database to flat files using SAP HANA Studio, upload the files to Amazon S3, and import them into an EC2 HANA instance.
Why wrong: Export/import is time-consuming and requires significant downtime.
- C
Use AWS Database Migration Service (DMS) with ongoing replication to migrate the database to Amazon RDS for SAP HANA.
Why wrong: DMS does not support SAP HANA as a source or target.
- D
Use AWS Backup to take a full backup of the on-premises HANA database and restore it to an EC2 instance in AWS.
Why wrong: Backup and restore involves longer downtime due to backup and restore times.
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 planning to migrate its SAP ERP system to AWS. The database is SAP HANA with a size of 3 TB. The company wants to minimize downtime during the migration. Which migration strategy should the company use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Use HANA System Replication to replicate the database to an EC2 instance running HANA in the target AWS environment, then perform a takeover.
HANA System Replication (HSR) is the optimal strategy for minimizing downtime because it continuously replicates data from the on-premises HANA database to an EC2 instance running HANA in AWS. When the migration window opens, a simple takeover (failover) occurs, typically completing in minutes, which meets the requirement for minimal downtime. This approach avoids the lengthy export/import or backup/restore processes that would take hours for a 3 TB database.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use HANA System Replication to replicate the database to an EC2 instance running HANA in the target AWS environment, then perform a takeover.
Why this is correct
HSR provides continuous replication with minimal downtime during the final switchover.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept

- ✗
Export the HANA database to flat files using SAP HANA Studio, upload the files to Amazon S3, and import them into an EC2 HANA instance.
Why it's wrong here
Export/import is time-consuming and requires significant downtime.
- ✗
Use AWS Database Migration Service (DMS) with ongoing replication to migrate the database to Amazon RDS for SAP HANA.
Why it's wrong here
DMS does not support SAP HANA as a source or target.

Why it's wrong here
Backup and restore involves longer downtime due to backup and restore times.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume AWS DMS or backup/restore services are suitable for SAP HANA migrations, but DMS does not support HANA as a target, and backup/restore methods cause significant downtime, whereas HANA System Replication is the only AWS-recommended approach for near-zero downtime migrations.
Detailed technical explanation
How to think about this question
HANA System Replication works at the persistence layer, using log-based replication to synchronize data between the source and target HANA systems. It supports both synchronous and asynchronous replication modes; for migration with minimal downtime, asynchronous mode is typically used to avoid latency impact on the source, with a final switch to synchronous mode before takeover to ensure zero data loss. The takeover process involves stopping replication, performing a log replay on the target, and activating it as the new primary, which can be completed in under 5 minutes for a 3 TB database if the network bandwidth is sufficient.
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.
