DBS-C01 Deployment and Migration Practice Question
This DBS-C01 practice question tests your understanding of deployment and migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to migrate its on-premises Oracle database to Amazon Aurora PostgreSQL. The company needs to automatically convert the Oracle schema to PostgreSQL-compatible format. Which AWS service should the company use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Schema Conversion Tool (AWS SCT)
AWS Schema Conversion Tool (AWS SCT) is designed specifically to convert database schemas from one engine to another, including Oracle to Amazon Aurora PostgreSQL. It automatically translates Oracle DDL (tables, indexes, stored procedures, functions, etc.) into PostgreSQL-compatible format, handling data type mappings, PL/SQL to PL/pgSQL conversion, and other schema-level transformations. AWS DMS handles data migration, not schema conversion, making SCT the correct choice for this requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
AWS Database Migration Service (AWS DMS) with the Oracle native dump and load option
Why it's wrong here
Native dump/load does not convert schema; AWS SCT is needed for schema conversion.
✗
AWS Server Migration Service (AWS SMS)
Why it's wrong here
AWS SMS is for migrating on-premises servers to AWS, not for database schema conversion.
✗
AWS Database Migration Service (AWS DMS)
Why it's wrong here
AWS DMS migrates data but does not automatically convert schema; schema conversion must be done separately with AWS SCT.
✓
AWS Schema Conversion Tool (AWS SCT)
Why this is correct
AWS SCT automates schema conversion from Oracle to Amazon Aurora PostgreSQL.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AWS DMS's data migration capability with schema conversion, assuming DMS can automatically transform the schema, when in fact DMS only moves data and requires SCT for schema translation.
Detailed technical explanation
How to think about this question
AWS SCT uses a built-in assessment report to identify incompatible Oracle features (e.g., Oracle-specific data types like BFILE, hierarchical queries with CONNECT BY, or PL/SQL packages) and suggests equivalent PostgreSQL constructs. It can also convert stored procedures by translating PL/SQL to PL/pgSQL, though complex logic may require manual refinement. In a real-world migration, SCT is run first to generate the target schema, then AWS DMS is used for ongoing data replication with change data capture (CDC).
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
