- A
Use SAP ASE replication to replicate data to an EC2 instance running ASE, then cut over.
Correct. Native ASE replication provides continuous, real-time synchronization, allowing a very short cutover window by applying only final transactions.
- B
Create a nightly backup of the on-premises database, copy to AWS, and restore.
Why wrong: Incorrect. Nightly backups result in data loss of up to 24 hours and require a long restore time, not minimizing downtime.
- C
Perform a full database export from on-premises and import into Amazon RDS for ASE.
Why wrong: Incorrect. Full export/import is time-consuming and cannot achieve minimal downtime due to the large data volume and lack of ongoing sync.
- D
Use AWS Database Migration Service (DMS) with ongoing replication.
Why wrong: AWS DMS does support SAP ASE as a source database, but it requires an initial full data load followed by ongoing replication. While this can minimize downtime, native ASE replication typically offers lower latency and a faster cutover because it avoids the full load phase and provides real-time synchronization. Thus, DMS is not the most appropriate strategy for minimizing downtime.
PAS-C01 Native ASE Replication Practice Question
This PAS-C01 practice question tests your understanding of technology. 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. A key principle to apply: native ASE Replication. 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 migrating an SAP ERP system to AWS and needs to minimize downtime during the cutover. The database is SAP ASE. Which migration strategy is most appropriate?

Correct answer & explanation
Use SAP ASE replication to replicate data to an EC2 instance running ASE, then cut over.
SAP ASE native replication (via Sybase Replication Server) allows continuous, real-time data synchronization from the on-premises ASE database to an EC2 instance running ASE in AWS. While AWS DMS supports SAP ASE as a source, it typically performs a full load followed by ongoing replication, which can introduce higher latency and longer cutover windows. In contrast, native replication minimizes downtime by keeping the target closely synchronized, requiring only a brief pause to apply final transactions and redirect clients.

Thus, DMS is not the most appropriate strategy for minimizing downtime.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is assuming AWS DMS is the best choice for minimizing downtime because it supports SAP ASE. However, native ASE replication provides even lower latency and a faster cutover, as it avoids the initial full data load required by DMS. The key is understanding that native replication is purpose-built for ASE-to-ASE synchronization and offers the shortest possible downtime.
Detailed technical explanation
How to think about this question
SAP ASE replication uses Log Transfer Manager (LTM) to capture transaction log records and apply them to the target database via Replication Server. This approach supports near-zero downtime cutover by maintaining a warm standby on EC2, and the final cutover involves a brief transaction log replay to ensure consistency. In practice, organizations often combine this with SAP's own migration tools (e.g., SWPM) to handle schema and application-level changes during the migration window.

Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Native ASE Replication Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
