The answer is AWS Schema Conversion Tool (SCT). SCT is the correct choice because it is purpose-built for offline schema conversion, handling the translation of stored procedures, functions, and data types from SQL Server to Amazon RDS for SQL Server without touching the actual data. Since the requirement is to minimize downtime and convert only the schema—not migrate the data—SCT performs this task in a disconnected, offline manner, leaving the source database fully operational. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between schema-focused and data-focused migration tools; a common trap is choosing DMS because it is a continuous replication service, but DMS is designed for ongoing data sync and would require downtime for schema changes. Remember the memory tip: SCT for Schema Conversion Tool—if the task says “schema only,” think SCT.
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 is migrating a 100 GB SQL Server database to Amazon RDS for SQL Server. They need to minimize downtime and ensure that only the schema is converted. Which tool should they use?

Correct answer & explanation
✓
AWS Schema Conversion Tool (SCT)
AWS Schema Conversion Tool (SCT) is the correct choice because it is specifically designed to convert database schemas (including stored procedures, functions, and data types) from one engine to another, such as SQL Server to Amazon RDS for SQL Server. Since the requirement is to minimize downtime and only convert the schema (not migrate data), SCT can perform an offline schema conversion without impacting the source database, whereas DMS is a continuous data replication tool that would incur downtime for schema changes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
AWS Database Migration Service (DMS)
Why it's wrong here
DMS migrates data and schema together; it is not solely for schema conversion.
✓
AWS Schema Conversion Tool (SCT)
Why this is correct
SCT is designed to convert database schema from one engine to another.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

✗
AWS DMS with schema conversion enabled
Why it's wrong here
DMS can perform schema conversion but is typically used for data migration; SCT is the dedicated tool.
✗
SQL Server Management Studio (SSMS)
Why it's wrong here
SSMS is a management tool, not a schema conversion tool.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS DMS (which handles data replication) with AWS SCT (which handles schema conversion), and assume DMS can perform schema-only migrations without realizing it always includes data transfer and potential downtime.
Detailed technical explanation
How to think about this question
AWS SCT works by connecting to the source SQL Server instance, extracting the schema metadata (tables, indexes, constraints, and code objects), and then generating a target schema script for Amazon RDS for SQL Server. It can also assess conversion complexity and provide action items for manual remediation of unsupported features, such as linked servers or CLR assemblies. In a real-world scenario, you would run SCT offline against a backup or read-only replica to avoid any impact on the production database, then apply the converted schema to the target RDS instance before starting data synchronization with DMS if needed.

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.
