Correct answer & explanation
✓
A target endpoint for the Amazon RDS for Oracle instance
AWS DMS requires a source endpoint to connect to the on-premises Oracle database, a target endpoint for the Amazon RDS for Oracle instance, and a replication instance to perform the data migration and ongoing replication. Option A (SNS topic) is for notifications, not a requirement for DMS replication. Option C (CloudWatch dashboard) is for monitoring, not a requirement. Therefore, the three necessary configurations are the source endpoint (E), the target endpoint (B), and the replication instance (D).
