PAS-C01 Migration Practice Question
A company is migrating a SAP system to AWS and needs to ensure that the database migration from SAP ASE to Amazon Aurora is successful with minimal downtime. Which AWS service should be used?
⚠ Common exam trap
It's easy for candidates to confuse AWS DMS with AWS DataSync, assuming DataSync can handle database migrations, but DataSync is strictly for file-based data transfers and lacks the heterogeneous database replication capabilities required for SAP ASE to Aurora.

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
✓
AWS Database Migration Service (DMS)
AWS Database Migration Service (DMS) is the correct choice because it supports heterogeneous migrations from SAP ASE (Sybase) to Amazon Aurora with minimal downtime. DMS can continuously replicate ongoing changes from the source database to the target using change data capture (CDC), allowing the source system to remain operational during the migration and enabling a cutover with only a brief outage.
