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
✓
The source database must have binary logging enabled (for CDC).
For ongoing replication (CDC) with AWS DMS, binary logging must be enabled on the source database (Option B). Additionally, the source database must be accessible from the DMS replication instance (Option C). Option A is incorrect because the source does not need to be running on EC2; any supported database can be used. Option D is incorrect because the target database in this migration scenario is SAP HANA on AWS, not Amazon RDS for Oracle. Option E is incorrect because AWS Schema Conversion Tool (SCT) is used for schema conversion, not a prerequisite for DMS replication.
