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
✓
AWS Database Migration Service
AWS Database Migration Service (DMS), is the correct answer because it is specifically designed for migrating databases to AWS with minimal downtime, and it supports ongoing replication from Oracle to Aurora PostgreSQL using change data capture (CDC). Option A is incorrect because AWS Application Discovery Service is used for discovering on-premises servers and applications, not for database migration. Option B is incorrect because AWS Server Migration Service (now part of SMS) is for migrating virtual machines, not databases. Option D is incorrect because AWS Schema Conversion Tool (SCT) is used to convert the database schema from one engine to another, not for ongoing replication; it is often used alongside DMS.
