Correct answer & explanation
✓
AWS Database Migration Service (DMS)
AWS Database Migration Service (DMS) can migrate the Oracle database to RDS, while the AWS Schema Conversion Tool (SCT) assesses the source database and converts the schema to target format. Option A (AWS Migration Hub) tracks migrations but does not assess databases. Option B (CloudEndure Disaster Recovery) is for server-level disaster recovery, not database assessment. Option C (AWS Snowball) is for offline data transfer, not assessment or migration planning.

Variation 1. A company is migrating a large on-premises Oracle database to Amazon RDS for Oracle. The database is 5 TB in size, and the migration must be completed within a week. The company has a dedicated 10 Gbps AWS Direct Connect connection. Which TWO AWS services should the company use to minimize downtime during the migration?
medium- ✓ A.AWS Schema Conversion Tool (AWS SCT)
- B.AWS DataSync
- C.AWS Snowball
- ✓ D.AWS Database Migration Service (AWS DMS)
- E.Amazon RDS for Oracle
Why A: AWS DMS can handle ongoing replication to minimize downtime. AWS SCT can convert the schema if needed, and AWS DMS can migrate data. AWS Snowball is for offline data transfer, which may not be needed with Direct Connect. RDS is the target, not a migration service. AWS DataSync is for file data, not databases. The correct options are A and D.
