DBS-C01 Deployment and Migration Practice Question
A company is planning to migrate a 2 TB Oracle database to Amazon Aurora PostgreSQL. The database contains large objects (LOBs) and uses stored procedures. Which TWO steps should the company take as part of the migration? (Choose two.)
⚠ Common exam trap
AWS often tests the misconception that DMS can handle schema conversion automatically, but DMS only migrates data; schema conversion requires a separate tool like SCT.
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
✓
Use AWS Schema Conversion Tool (SCT) to convert the Oracle schema and stored procedures to PostgreSQL-compatible format.
The AWS Schema Conversion Tool (SCT) is specifically designed to convert Oracle schema objects, including stored procedures, to PostgreSQL-compatible format. Since the migration involves stored procedures, SCT is necessary to handle the syntax and logic differences between Oracle PL/SQL and PostgreSQL PL/pgSQL, ensuring the target database schema is ready for migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set up AWS DMS ongoing replication to keep the target in sync after migration.
Why it's wrong here
Ongoing replication is for minimal downtime migrations, but not a required step for all migrations.
- ✓
Use AWS Schema Conversion Tool (SCT) to convert the Oracle schema and stored procedures to PostgreSQL-compatible format.
Why this is correct
SCT converts schema and code objects like stored procedures.
- ✓
Configure AWS DMS with full LOB mode to migrate large objects.
Why this is correct
Full LOB mode ensures LOBs are migrated without truncation.
- ✗
Use AWS DMS native Oracle to PostgreSQL endpoint to migrate data without schema conversion.
Why it's wrong here
DMS can migrate data, but schema conversion is typically done separately with SCT.
- ✗
Enable RDS Proxy to reduce connection overhead during migration.
Why it's wrong here
RDS Proxy is for production connection pooling, not a migration step.
