PAS-C01 Technology Practice Question
A company is planning a migration of their SAP ERP system to AWS. They want to use SAP HANA as the database. The current on-premises database size is 2 TB. The migration must have minimal downtime. Which combination of AWS services and methods should be used to achieve a near-zero downtime migration?
⚠ Common exam trap
Candidates often confuse SAP HANA System Replication (HSR) as a native AWS service or assume AWS Backup can handle on-premises continuous backups, when in fact AWS DMS with CDC is the only option that provides a managed, near-zero downtime migration path for SAP HANA to AWS.
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 AWS DMS with a SAP HANA source and target, configuring ongoing replication to minimize downtime
AWS DMS with a SAP HANA source and target, configuring ongoing replication, is correct because it supports near-zero downtime migration by continuously replicating changes from the on-premises HANA database to the target HANA database on AWS until cutover. DMS uses log-based change data capture (CDC) to capture ongoing transactions, allowing the source to remain operational during the bulk load and then switch with minimal interruption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use AWS DMS with a SAP HANA source and target, configuring ongoing replication to minimize downtime
Why this is correct
DMS supports ongoing replication to keep data in sync with minimal downtime.
- ✗
Use AWS Database Migration Service (DMS) with an SAP HANA source and S3 as target
Why it's wrong here
DMS cannot directly replicate to S3 as a target for HANA.
- ✗
Use SAP HANA System Replication (HSR) to replicate data to an EC2 instance in AWS
Why it's wrong here
HSR requires HANA setup on both sides and can be complex for migration.
- ✗
Use AWS Backup to perform a continuous backup of the on-premises HANA database and restore to AWS
Why it's wrong here
Backups are not real-time and involve downtime.
